Water Distillers

Distillation is one of the surest ways to have clean water for home use. There are no added chemicals and it effectively gets rid of water pollutants including disease-causing micro-organisms.

What Is A Water Distiller?

Distillation is a process that occurs naturally on our planet and has been simulated in a machine. A water distiller purifies water by boiling it to its evaporation point, separating water from impurities such as chemicals, minerals, and dissolved solids. Here is an in-depth look at how this actually works.

best water distiller

How A Water Distiller Works

A water distiller can either be connected directly to your water supply, or you have to manually fill the machine with water. Either way, the same working mechanism applies.

Distillation starts with a heating element that boils water into steam. Steam has a higher boiling point than almost all water contaminants that are separated from the water as it evaporates. Steam is then directed to another chamber and cooled through condensation for clean, purified water.

Distillation is one of the most effective ways to purify water of harmful chemical substances. Distilled water usually has a pH of 7 but reacts with carbon dioxide and becomes slightly acidic with a 5.8 pH. Water distillers with a carbon filter can help alkalinize the water after distillation.

Who Will Need A Water Distiller?

Water distillers are recommended wherever you need highly purified water. They are most beneficial when you need water that does not have any hard minerals.

Domestically, it is good for watering plants and filling aquariums since you can control what minerals are present in the water. Machines that use a heat element and water, for example, steam iron or humidifier also require distilled water that will not clog up moving parts with mineral deposits. Distilled water is also great for drinking but lacks health minerals that are good for you.

Commercially, water distillers are used in cooling systems as it does not leave any mineral deposits on metallic surfaces, improving durability and efficiency.

Whether you are a new or experienced buyer, a good water distiller will serve you for years and work efficiently to constantly produce clean and pure water. We have identified the best water distillers available based on budget and features. This will help you pick a distiller that is high quality and made to serve your needs.

Water Distillers’ Buyer’s Guide

Water filtration is a wide topic that can easily get overwhelming to digest. To help you along, here are tips on how we chose the above water distillers so you can find one that suits your situation. There is no one size fits all solution but preference will vary according to need and budget.


This is a measure of how much your water distiller can hold at once before you need a refill. The capacity of your distiller should match your water demands depending on how many people use it.

The capacity of your water distiller will influence the size and style of your unit. Large capacity units generally take up more space and may not fit in your kitchen. They have an undesirable industrial finish that is better fitted in a basement and are generally noisy.

Small countertop water distillers need to be refilled but produce less heat while in use. They are generally cheaper and are designed to match modern kitchen décor.

Flow rate

Distillation is generally a slow process unless when done on an industrial scale. The fastest filter rate of water distillers available is 2 and a half hours with other units taking double the time. This consideration is only important for large families that will require a constant flow of purified water.

There are units that have a carbon filtration stage after distillation. Though this may considerably reduce your flow rate, it will improve the taste of water by adding alkalinity.


This is probably the most important feature to consider when buying a water distiller. Distillers come with a heating element which requires a material that can withstand high temperatures. Stainless steel is the most highly recommended material because it can get hot but does not leach any toxins to your water, unlike plastic.

Stainless steel is durable under high temperatures though it is more costly. Glass jars and non-plastic components for example the carafe and nozzle respectively, ensure water stays pure without contact with metal or plastic.


Water distillers require regular cleaning to avoid mineral deposits settling in your unit. Ensure you find one that is easy to clean and has large openings so you can get to all the little nooks and crannies.

All replaceable parts on a water distiller will also need regular maintenance especially if it comes with carbon filters. Ensure you can easily access replacement water filter cartridges if need be and also factor in the maintenance cost in your budget.


Water distillers are heavy-weight machines that work for long hours at a time and require professional expertise to run in case it breaks down. Look out for one with a warranty that is as long as possible so you do not have to incur recent maintenance costs.


Whether you are a geek looking to have pure water for science experiments or need it for your aquarium, distillers are effective for having clean water around the home. Installing a water distiller in your home is cost-efficient and will pay for itself after long years of use.

Distilled water is free of all minerals which can affect the taste of water and reduce its health benefits. For maximum functionality, remineralize your distilled water with healthy compounds such as calcium if it is intended for drinking.

Aquasana EQ-1000-AST Whole House Water Conditioner and Filter System

Key Features:
  • It can handle water hardness levels of up to 25 GPG
  • Remarkably effective at reducing chlorine levels
  • Larger capacity of up to 1,000,000 gallons

Aquasana is a brand that’s very famous for its durable, complex systems that can be customized to address various water treatment needs. The EQ-1000-AST model stands out as one of the best water treatment systems from the company as well as on the market.

It’s an innovative whole-house unit that combines an effective water conditioner with an advanced water filter system to provide a comprehensive solution to a broad range of water quality issues.

This system is part of Aquasana’s EQ-1000 series which consists of two other models, the EQ-1000 and EQ-1000-AST-UV. In this review, we look at the EQ-1000-AST model which is our top pick on this list and you are going to see why we consider it as the best whole house water conditioner.

System Design and Performance

The Aquasana EQ-1000-AST is a water conditioner and a filter system in one unit. It features 4-stages of water treatment which include, a sediment pre-filter, salt-free water conditioner, activated carbon filter, and a post filter.

The EQ-1000 which is the base model of the Aquasana EQ-1000 series is only a filter system without the salt-free water softener. The EQ-1000-AST-UV, on the other hand, is the more advanced model of the series equipped with the water conditioner and filter system plus an extra UV sterilization filter.

Softening Capability

The Aquasana EQ-1000-AST offers an entirely salt-free water treatment process using its Simply Soft descaling system.

Simply Soft descaling system is an innovative and proven SCM (Scale Control Media) softening technology that naturally conditions water without using added sodium.

First, the water from your main supply line goes through a pre-filter that clears out sediments, silt, sand, and rust.

Once filtered, it’s sent through the Aquasana salt-free water conditioner tank where the SCM technology modifies the structure of the minerals that cause water hardness (calcium and magnesium) by transforming them into a crystal structure which inhibits the minerals from bonding and creating scale build-up.

It’s an all-natural and chemical-free approach to preventing scale from forming and at the same time, it also protects your plumping and pipes from corrosion in the long run.

The descaler will also not demineralize your water. The beneficial calcium and magnesium minerals will not be removed, but you will still get the benefits similar to soft water.

In terms of water harness level, this Aquasana descaler can handle water hardness levels of up to 25 GPG. However, it works well at 15 GPG or below. If your water hardness level is above 15GPG, then it may not be that effective.

Filter System Performance

When it comes to the filtration system, the EQ-1000-AST uses a four-stage filtration process that efficiently removes a wide range of common contaminants found in water.

The 1st stage consists of a sediment filter that strips out dust, dirt, rust, silt, and any other particle or sediment larger than 5 microns to protect the media in the later filtration stages. From there, the water is sent through the water conditioner tank for descaling.

After the softening process, the now descaled water enters the 2nd stage of the filtration process which takes place in the top tank right after the descaler.

Inside this tank is a combination of a copper-zinc oxidation media (KDF-55 medium) and crushed mineral media which effectively draw out 97% of chlorine in the water, and also reduce scale along with some water-soluble heavy metals such as lead and mercury.

Both media are bacteriostatic too meaning they will prevent bacteria and algae growth within the system. Moreover, they can equally enhance the pH of the water like an alkaline filter in an RO system making it slightly alkaline which is commendable as alkaline water is an antioxidant and considered better for our bodies.

The 3rd stage is an activated carbon filter that sits in the bottom tank below the 2nd stage. The activated carbon media is sourced from coconut shells and it helps in further removal of chlorine alongside other harmful chemical contaminants like VOCs, herbicides, pesticides, and industrial solvents.

The 4th and final stage is made up of a 0.35-micron post-filter which is an important if not necessary addition to the system. It’s the finest filter you will find in any conventional whole house water system and ensures no sediment, organic particle or microscopic cysts remains in your water.

With this really impressive filtration process coupled with a reliable descaling technology, the EQ-1000-AST is not only capable of stopping limescale buildup within your plumbing system, but will also give you cleaner, great-tasting drinking water.

The only thing missing is the UV sterilization filter which is an optional upgrade you can get if your water has high bacterial or microorganism contamination.

However, it’s included in the EQ-1000-AST-UV model and it’s the only feature that differentiates it from this EQ-1000-AST model. It does drive up the price a little bit, but it will destroy up to 99.99% of all microorganisms in your water supply.

System Capacity

Besides the highly-effective water treatment system, the Aquasana EQ-1000-AST offers one of the largest filtration capacities out there for a whole-house unit.

Its descaler system can process up to 1,000,000 gallons of water which translates to about 10 years of service for small to medium-sized families with average water consumption.

What’s more, the multiple stages of the unit don’t have a significant effect on the water flow. The system maintains a maximum flow rate of 7 GPM which is sufficient for small to large homes.

Installation and Maintenance

Installing the EQ-1000-AST is relatively easy, but it will need a bit of plumbing knowledge because it may require doing some little changes on the piping for most houses.

You can do it yourself although it’s not advisable because according to Aquasana, the installation must be done by professional plumper in order to engage the warranty.

Once installed, maintaining this system is pretty simple. There is no backflushing or draining needed. The only maintenance needed is replacing the filters.

The pre-filter, KDF-55, and carbon filter require changing every 3 to 6 months depending on your water quality. The post-filter should last about 12 months while the water conditioner tank will last for 10 years.

In addition, the unit comes with brass fittings and shut-off valves to enable more straightforward and mess-free filter changes. Its unique up-flow dual-tank design also does well to prevent any chances of clogging.

Final Thought

There are no serious drawbacks to worry about with this Aquasana system. You should, however, bear in mind that it will require professional installation so as to engage the maximum 10-years warranty which is the longest we’ve encountered in our reviews.

The other thing is that this system is not ideal for well water treatment due to high levels of iron and other contaminants that require specialized filters like an iron filtration tank and UV sterilization filter.

To sum it all, from our thorough assessment, the Aquasana EQ-1000-AST indeed has all it takes to stand out as the best whole house water conditioner in a crowded market. Its price may fall on the high end, but what you get is one of the most effective and long-lasting units that’s worth every penny.

APEC Water Systems FUTURA-10 Water Conditioner System

Key Features:
  • Faster water flow at 10 GPM
  • Robust and very durable construction
  • Advanced ceramic media removes hardness of up to 25 GPG

APEC Water Systems enjoys a high reputation in the industry for making water systems that are specially tailored for performance, durability, and reliability. These include the whole house salt-free water softeners and the FUTURA-10 water conditioner system is one of them.

It’s amongst the most robust salt-free water softeners on the market with an excellent softening capability. The unit comes as a water conditioning system only, but APEC offers two other similar models in the same category that are equipped with extra filters.

There’s the APEC WH-SOLUTION-MAX10 which is a two-stage whole house water system and the APEC WH-SOLUTION-10 which is a three-stage system.  

With that in mind, we will analyze the key features of this APEC FUTURA-10 model and also highlight the complementary filters that the two other options come with to give you a better comparison of the three models.

Softening Capability

The FUTURA 10 employs a salt-free water softening approach using advanced ceramic media that provides an all-natural solution to scale prevention and reduction.

When water from the main supply line comes into contact with the surface of the media, the minerals that cause hardness, calcium (CaCO3) and magnesium, get attracted and attached to the ceramic granules where they become converted into a crystalline form.

In this crystal stage, the minerals are harmless, neutral, and completely stable hence are unable to attach to any surfaces such as pipes. When the crystals become too big in the range of nanometers, they detach from the granules and then get carried away as the water flows through the system.

This advanced ceramic media can remove water hardness by as much as 25 GPG and it will also effectively reduce the existing scale already in your plumbing system and fixtures like water heaters and showerheads.

It will neutralize the hard water properties without removing the minerals which is another benefit if you prefer taking water that contains natural essential minerals like magnesium and calcium. Another advantage is that the catalytic ceramic granules are not consumed during the conversion process, so they can last for a very long period.

There are no additional filtration stages in this FUTURA-10 model but as I mentioned earlier APEC Water Systems has two other options under this category that come with extra filters.

The APEC WH-SOLUTION-MAX10 is one of them and it’s a two-stage whole house water system featuring a catalytic granular activated carbon filtration system in the 1st stage for removing chlorine and other chemical contaminants, and the Futura salt-free water conditioner in the second stage.

The APEC WH-SOLUTION-10 is the other option and the most comprehensive of the three models. It’s a three-stage system featuring a whole house sediment pre-filter in the 1st stage that clears out particles and sediments in the water.

The 2nd stage consists of a catalytic carbon filter that removes common chemical contaminants like chorine while the third and final stage is the Futura salt-free water conditioner.

Therefore, depending on your particular needs and the condition of your water, you have the option to choose a water conditioner with filters or without filters.


The Futura 10 is perfect for the average family home. It can soften up to 10 gallons of water per minute which is an impressive flow rate, sufficient enough to provide adequate water to an entire home without a drop in pressure.

You can take a shower while running the dishwasher and doing laundry at the same time, yet you won’t experience any drop in pressure. It’s designed to work with up to 3 bathrooms simultaneously.

Installation and Maintenance

Like the AO Smith Water Descaler above, the FUTURA-10 is a single tank system that’s easy to install and would fit anywhere with ease. You just need to connect it to your house’s main water supply line and you are good to go.

The system has no backwash function nor does it require electricity and drainage for wastewater. It’s a maintenance-free unit that you install and let it run. The media will, however, require replacement once every 3 to 5 years.

Overall, the Futura-10 is a robust system and an effective solution for families looking to solely combat limescale in their water. It’s a premium product that’s worth checking out if you are after great quality and performance plus it comes with a long 10 –year limited warranty.


  • Advanced ceramic media removes hardness of up to 25 GPG
  • Retains the hardness minerals in the water
  • Faster water flow at 10 GPM
  • Robust and very durable construction
  • Installation is a breeze and requires minimum maintenance
  • Comes with a 10-year limited warranty and life-time support


  • Not ideal for use with well water

LiquaGen Salt-Free Water Conditioner System

Key Features:
  • Filters out dust, rust, sand and other particles
  • Large capacity of up to 1,000,000 gallons
  • Impressive 12 GPM water flow rate

The LiquaGen salt-free water conditioner is another large capacity system on our list that presents high efficiency as well as great results with regards to descaling and filtering water at home. It’s a combination of a water conditioner with a filtration system which makes it a good choice for those who want a unit that can address more than just water hardness.

Softening and Filtration Capability

This LiquaGen unit comes as a two-stage system consisting of a sediment pre-filter tank and the LiquaGen water conditioner tank.

When installed, the water first goes through the 1st stage tank which features a polypropylene sediment pre-filter that removes dust, rust, silt, and other particles present in the water down to 5-microns. This filter is 100% melt-blown polypropylene filtration media which is amongst the best in the market and provides exceptional dirt-holding capacity. 

From the sediment pre-filter, the water enters the LiquaGen water conditioner tank which contains a salt-free scale removal media that neutralizes the hardness minerals calcium and magnesium.

Once neutralized, the media further transforms the hardness minerals into a crystallized form hence preventing them from sticking to internal pipes and plumbing as scale deposits. This media is so effective that it can prevent limescale build-up up to 99.6%.

Besides that, the scale deposits already inside your pipes and fixtures will dissolve and detach from the pipes over time thereby enhancing the flow and efficiency of your plumbing system. The conditioner also retains the minerals, so you get healthy water for drinking and other applications.

System Capacity

In all the 8 units on this list, this LiquaGen system and the Aquasana EQ-1000-AST model are the only options that give you a pretty large capacity.

The LiquaGen’s scale prevention media can process as much as 1,000,000 gallons of water before needing replacement which means you will be able to use it for about 5 to 7 years. It’s a large tank that’s designed to serve the entire water supply of a home.

The water flow is equally high as it can soften up to 12 gallons of water per minute. This, in fact, is the second-highest flow rate we’ve covered and it’s capable of meeting the demands of any medium to a large house or 3 bathrooms simultaneously.

Installation and Maintenance

The installation process of this water conditioning system from LiquaGen is fairly easy as long as you have some plumbing knowledge or you are an experienced DIY installer.

Otherwise, you may have to get a professional plumber to set it up because it’s designed to be installed outdoors with weatherproofing and the package includes all the parts required for installation.

As for maintenance, the only work involved is replacing the sediment pre-filter every 6 to 12 months based on the condition of your feed water. The media inside the conditioning tank will last up to 7 years before needing replacement.

In general, with the large capacity, fast flow rate, and an effective water conditioning process, this LiquaGen salt-free softener is a unit that would work well with larger homes. It’s also bound to satisfy the needs of anyone who is after efficiency.

Simplicity is what defines best this Triple Action salt-free water conditioner. However, while it may have a pretty simple design, this unit comes packed with some amazing and unique features that set it apart from the rest. It performs three separate functions within one compact system.

Softening Capability

As its name suggests, the Triple Action PSC1 water softener is a 3-in-1 water treatment system that includes a combination of scale control, water filtration, and iron/bacteria filtration.

The incoming water first goes through the scale control core (Hard Water Bullet) which breaks down calcium carbonate and other hard minerals in the water into aragonite crystals.

These aragonite crystals are a much smaller, softer, and harmless form of calcium that can’t build up limescale like the normal calcium in the water. This unique softening process is the main difference between the Triple Action PSC1 and the other standard salt-free water conditioners on this list. There are no grains involved here.

From the scale control core, the water passes through a polyphosphate capsule that contains about 6 oz of food-grade polyphosphate crystals.

The phosphate dissolves slowly into the water as it passes through the crystals coating the aragonite and hard water minerals and making it impossible for them to precipitate out of water and form limescale build-up. It ties them up and keeps them in suspension.

The conditioned water then goes through the stainless steel 25-micron screen filter and finally through the 2-micron bacteria/iron outer filter which clears out iron as well as intestinal parasites such as cryptosporidium and giardia.

With these four stages of water treatment, this unit will be able to give you clean water that’s naturally conditioned as Watts OneFlow Plus the treated calcium is not removed in the process.

It’s kept in suspension by the polyphosphate crystals, thereby you get the additional health benefits of having the essential minerals retained in the water. The system can remove water hardness of up to 25 GPG and it can work with either city or private well water.


The Triple Action PSC1 water softener gives you a capacity of at least 10, 000 gallons of water which is amongst the lowest on our list. This is because it can only support around 10 oz of polyphosphate crystals which is enough to last you about 6 months after which you have to refill it again.

Despite this low capacity, the PSC1 has one of the fastest flow rates when it comes to water conditioning units. It can process up to 30 gallons of water per minute which is quite impressive and certainly means you will hardly experience any decrease in water pressure.

Installation and Maintenance

Setting up the Triple Action PSC1 is not that hard if you are a handy person. It’s a compact unit that you can even install in an RV and the mounting bracket plus the housing wrench are included in the package. These are vital additions that will make the installation process significantly easier.

The best part about this unit is that you can also install it outside as its body is made of strong BPA-free plastic. It’s a high-impact, waterproofing housing that’s built to last many years and withstand outdoor conditions provided it does not freeze.

Like any other filter-based system, the PSC1 will require some little maintenance which is recharging the polyphosphate crystals after about every 8 to 12 months.

The only other thing you will need to do is clean up the scale control core (Hard Water Bullet) and the stainless steel screen filter. That’s all and the polyphosphate comes already preloaded in the system.

If there are any setbacks to point out it would probably be the fact that the inlet is 1-inch thick which means you may need to get some connectors to ensure proper fitting.

Considering both the unique yet very effective scale control process and additional filtration stages, it’s clear that the Triple Action PSC1 is a decent unit that’s not only functional but well-built and durable. It can even be installed outdoors and won’t eat up huge space.

Hardness NG Lotus Whole House Water Conditioner

Key Features:
  • Removes sediments and particles down to 2 microns
  • Maintains high water flow of up to 30 GPM
  • Compact design with robust construction

The Hardness NG Lotus system closes our top 8 whole house water conditioners list. Featuring an almost similar design and water conditioning process to that of the Triple Action PSC1 model above, this is another unit that guarantees you remarkable results when it comes to preventing scale buildup in water and plumbing systems. 

Softening Capability

Like the Triple Action PSC1, this system features a 3-stage whole house water treatment concept that ensures clean, safe, and healthy water in every outlet of your house.

First, the incoming water goes through the water conditioning cartridge which contains crystals that alter the structure of the hard minerals so that they are unable to create limescale buildup inside the pipes and fixtures.

The conditioner also helps eliminate existing scale deposits in your water plumbing system and there’s no reduction in the essential minerals, it only changes their structure. This unit will basically handle both well and municipal water because it’s designed to withstand extreme water hardness.

The already conditioned water then flows through a stainless-steel mesh filter that captures dust, sediments, and other impurities larger than 25 microns.

From there, it goes through the final filtration process which is an extra post filter that further removes any remaining sediment or particle that’s larger than 2-microns.


Unlike other conditioners and filters on our list, the Hardness NG system does not have a limit on the number of gallons of water it can filter. This is possible because the stainless-steel mesh filter can be easily removed and cleaned every month.

When installed, this system does not affect water pressure in your plumbing system. Instead, it ensures a flow rate of 30 GPM is maintained so that you can get an adequate flow of water to taps, showers, and all fixtures.

Installation and Maintenance

The tiny size of this unit makes it easy to install, plus it does not occupy much space. However, if you are not skilled in this kind of installation, it’s important to hire a professional plumber. You can install it either indoor or outdoor without any damage to the unit.

You do not need to worry much when it comes to maintenance either. It’s an easy process, requiring only monthly washings to keep the filter clean. Apart from that, the cartridge and post-filter need replacement after every 6 months to keep the system working properly.

Unfortunately, this unit will not be able to remove chlorine, heavy metals, bacteria, viruses or germs from the water. However, if combined with under sink reverse osmosis system, then you are assured the best results.

In short, this small but mighty Hardness NG Lotus whole house water filter and conditioner can get you clean, scale-free water at half the price of larger units. It’s a water treatment system to go for if you are looking for something reliable and affordable.  


  • Effectively prevents limescale buildup
  • Removes sediments and particles down to 2 microns
  • Retain beneficial minerals
  • Maintains high water flow of up to 30 GPM
  • Easy to install and maintain
  • Compact design with robust construction


  • The cartridge and post-filter need to be changed every 6 months
  • It does not remove chlorine, bacteria or viruses

Water Conditioner

Hard water has been a very common problem for a long time and we can all agree that its effects are annoying and irritating especially when it comes to plumping systems and appliances.

Fortunately today, there are several types of water softeners in the market and one very convenient and affordable option is none other than salt-free water softeners.

These growing water treatment systems are great alternatives to the traditional salt-based (ion-exchange) water softeners.

They are effective and can combat the harmful effects of water hardness without requiring frequent monitoring and replenishment every week like salt-based systems.

Understanding how they function is a great advantage when making a purchase decision and our comprehensive reviews below will throw more light and help you easily narrow down to the right unit for you.

So if you struggling with extreme water hardness and you are searching for the best salt-free water softener, you are not out of luck. Read on for a list of top models and more information to make your purchase process easier.

A water conditioner is an alternative water softening device that’s equipped with some type of cartridge or tank containing a special scale control media that help transform hardness mineral ions in the water into a stable and harmless form that won’t adhere to surfaces.

best water conditioner

Water Conditioner Working Process

Water conditioners are usually made up of a single cartridge or tank system filled with resin beads or another descaling media. Most work through a physical process known as Template Assisted Crystallization (TAC) to alter the way hardness minerals in water behave.

In this template-assisted crystallization process, water is passed through a tank/cartridge of TAC media which consists of tiny polymer/ceramic beads that are covered in craters called nucleation sites that act as templates to create micro-crystals.

When the hard water from the mains supply comes into contact with the TAC media in the tank/cartridge, the calcium and magnesium ions get caught by the nucleation sites.

Therefore, as the water flows into the cartridge, more magnesium and calcium ions continue to build up within the sites upon which they are changed into small micro-crystals.

Eventually, when these micro-crystals reach a certain size, they break off of the media where they are then released into the water.

These crystals are stable and flow through the water and the plumbing system with their crystalline structure intact. They don’t break off and are unable to attach themselves to water pipes or appliances as scale as the regular hard minerals do.

The result is complete prevention against scale build-up, but the minerals remain present in the water which is a great advantage since they are healthy to humans and in this crystalline form, they can’t damage the plumbing system.

However, it’s important to note that, the scale control media used by whole house water conditioners may vary greatly from one brand to another. Furthermore, several models come equipped with extra filters to help tackle other issues aside from water hardness like removal of contaminants

They can come with a sediment pre-filter and/or a carbon filter to take care of particulates and chemical contaminants like chlorine.  Others even include more advanced filters like a UV sterilization filter or an iron filtration tank that can help soften and treat well water.

Benefits Of A Water Conditioner

There are several advantages and benefits to using salt-free water conditioners that make them stand out from traditional water softeners. Some of these benefits include:

A Variety of Applications

Water conditioners come in different cartridge sizes and flow rates. If you don’t wish to install a whole-house water conditioner you have a variety of other options to choose from like a single-cartridge system that you can set up in line with other water filtration systems or in front of a tankless water heater.

Aside from that, there are other whole house water conditioners that offer more extensive filtration abilities. They come with additional filter media along with the salt-free conditioner cartridge.

Therefore, aside from inhibiting scale build-up and removing existing scale in pipes, these water conditioner systems will tackle other water issues. A good example is a whole-house water conditioner and chlorine reduction system which not only prevents scale accumulation but also improves the odor and taste of your water supply. 

Low Maintenance and Media Consumption

Another key benefit you get from using a water conditioner is the maintenance-free aspect. They are very low maintenance systems as the tank/cartridge of resin beads doesn’t need ongoing regeneration.

It takes very little TAC media to sustain a whole-house water conditioner system as many units only require about 5 to 10 liters of media which can last several years. Generally, you will be replacing the media once every 3 to 5 years.

Installing a water conditioner system is also remarkably simple since most come as a single tank or cartridge. No wastewater is generated, so they don’t require drain connections. They also don’t need electricity to operate and have no dramatic effect on the water flow rate.

Healthy Mineral Remain in Water

Water conditioners prevent the formation of limescale but at the same time leave healthy minerals in the water which are beneficial for your health. Furthermore, they won’t raise the sodium content in the water like salt-based water softeners.

Soft Water Alternative

Soft water tends to have a “slippery” feel which not most people like. Other people also complain that showering in soft water often leaves one feeling like the soap is still sticking to the skin or the shampoo never completely washes out of their hair.

Although all these are purely preferential, if you don’t like how soft water feels but still want to ensure scales are removed from your plumbing, then a water conditioner can give you exactly that. It doesn’t eliminate the hardness minerals, instead, it only makes them ineffective such that they can’t adhere to surfaces.

Environmentally Friendly  

Water conditioners don’t produce any wastewater as they don’t go through regeneration cycles. Therefore, no salt or other chemicals will get dumped into the waste stream.

In addition to that, they save water because all the water that gets processed through the system flows right into your home water supply or tankless heater.


One of the major impacts of limescale build-up is the reduction of the efficiency of your plumbing system and water heating appliances. By installing a quality and reliable water softening system, you can eliminate and help prevent these problems.

Salt-free water softeners, both water descalers, and water conditioners provide a great alternative option to traditional salt-based systems. They are effective, relatively affordable, and reduce the need for expensive salts as well as frequent monitoring and brine washing.

If you have read our reviews above and compared the different options we’ve listed, then we believe you will have little difficulty evaluating and choosing the best salt-free water softener that will meet your needs.

One thing you want to make sure though is that you take into consideration the water condition in your home before settling on a particular model.

What is a faucet water filter?

A faucet water filter is a small point-of-use system that attaches directly to your tap. It removes several water contaminants, ensuring water is safe for drinking, cooking, and cleaning.

Faucet filters mainly rely on activated charcoal filters and are easy to install.

best faucet water filter

How does a faucet water filter work?

Faucet water filters enhance the taste and smell of water by flowing it through a series of layers.

First, there is a filter screen that safeguards the filter system and traps large pollutants such as rust, sand, and debris.

Most models use chemical filtration to absorb contaminants, often through an activated carbon filtration stage. The activated carbon is porous and attracts contaminants as water flows through it. This requires a significant amount of time, hence a noticeably reduced flow rate when using a faucet filter.

Who will need a faucet water filter?

Faucet mount water filters are a great solution for renters who cannot install a permanent whole house filtration system in their homes. You can always carry it with you and it does not make permanent changes to your water system.

If you spend lots of time outdoors, a faucet filter can be beneficial. It is easily portable and lets you access clean, safe water for cooking and drinking from any source.

Faucet mount water filters are ideal for those looking for an easy to maintain and install water filtration system. They do not require any plumbing systems and can be installed by anyone. Additionally, they are cost-effective compares to reverse osmosis or whole house filtration systems.

Buying Guide

Most faucet mount water filters work in the same way though they are built differently. To find one that works for you, there are a few things to consider, and below are a few to get you started.

Filter Quality

Filter cartridges are the biggest consideration before you purchase a faucet water filtration system. They remove water contaminants from water and can eliminate more than 70 pollutants, depending on the brand.

Once you test your tap water, look for a filter unit that removes most of the contaminants you find. It may be impossible to find one that is 100% efficient, but most will get the contaminants below EPA standard limits.


Faucet water filters are generally small compared to other water filters. The size and design of your filter will determine how much space it will occupy. In case you have a small sink, a bulky unit would be hard to maneuver especially when cleaning dishes.

Size is directly proportional to the capacity of your faucet mount filter. Most range from 100 to 300 gallons, a feature to take note of when buying for a large family.

Finish and Durability

When choosing the right water filter, consider how long it will last and it’s fit in the kitchen. Filters with stainless steel housing are usually favored over plastic ones as they last longer and are aesthetically pleasing.

There are faucets that can rotate around their horizontal and vertical axis. This style is convenient for unhindered use of your kitchen sink when you need the space.

Ease Of Setup & Maintenance

Faucet mount water filters are easy to install and do not require the services of a plumber. They connect directly to your faucet and come with installation hardware if needed. An easy-to-install water filtration system is reliable in case you need to move it or change the filter cartridges.


Faucet mount water filtration is one of the most affordable ways to have clean, freshwater. When considering your budget, it is important to factor in added costs such as the cost of replacement filters and the filter’s lifespan.

How Does A Countertop Water filter work?

Countertop filters are really simple to install as all you need is to attach your filter’s tubing to your kitchen faucet with a diverter connector and you are ready to go.

When you turn your tap on, water goes through the tubing, through the filter layers, and out of the dedicated faucet.

The diverter lets water comes out of your regular faucet or lets water goes through the filter with a switch.

Who Will Need A Countertop Water Filter?

A safe and pure water option is important because tap water is considered unsafe. An effective water filter is one of the easiest ways to keep a healthier lifestyle for any home type.

It is an ideal option for renters and people who are looking to save on space. Countertop filters are easy to install and do not require any permanent changes to your plumbing system.

Countertop filters are convenient. They are easy to maintain and can be installed by anyone. If you are looking for an affordable and quick solution, this may work well for you.

Choosing The Best Countertop Water Filter

There are lots of water filter systems and this makes it a task to look for one that you like and fits you.

Before you get overwhelmed, here are a few pointers on what to look for and how to narrow down your choices to the best one for you.


The easiest place to start when looking for a water filter for your home is the capacity of the unit you wish to buy.

Not to be confused with the filter life, this refers to how many people the filter you intend to purchase can serve.

Countertop filters offer more volume than pitchers and do not need constant refilling. However, they are meant for fair use and may not be ideal for large families.

This is because larger systems are more effective in removing contaminants from larger water supplies without slowing the water’s flow rate.

Fit Your Needs

Before going out to purchase a filter, find out what is in your tap water.

You can test with a water test kit or ask your water supplier for detailed information. This is because water filters are designed to filter specific contaminants that need to suit your location.

At a minimum, countertop water filters are made to filter the chlorine and make your water taste better. The best rule of thumb is to look for a countertop filter that removes at least 90% of all contaminants in your water.

That said, always ensure the filter comes with an NSF certification as this is the only way to validate a manufacturer’s removal claim before purchase.

Ease Of Use

Countertop filters are really easy to install and require low maintenance. However, there are some that are simpler than others, hence easier to maintain.

All countertop water filtration systems use filter elements that do require you to replace them. This is easy to do and the filter’s lifespan is usually indicated on the product.

This is however an estimate and will vary depending on the quality and amount of water you use.


Budget is important when buying anything, even a water filter. A countertop water filtration system runs for as low as $20 to $1000. This is considerably cheaper than large whole house filter systems.

Added to the initial cost, is a maintenance expense in filter replacement that you should consider before making your final decision. Paying more does not always mean better and you should therefore do in-depth research and get one that is affordable but matches your requirements.

Size & Design

With all the above in mind, determine where your water filter will sit so as to buy one of the appropriate sizes.  Countertop filters are generally small but there are some that would not be considered portable.

Lastly, keep aesthetics in mind. Though it may not be essential, countertop filters can be an eyesore unless you find one that matches your décor.


Truly, there is no one-size-fits-all when it comes to the right countertop water filter since all models are made to remove specific pollutants.

Once you know what’s in your water, it is easy to choose a model that is effective and works for you.

Clean water is a basic need of life and should be accessible to all. Unsafe drinking water is estimated to cause 502 000 diarrhoeal deaths each year and has long-term negative effects on our societies.

Keep your families safe and enjoy clean, healthy tap water from the comfort of your home using any of the countertop filter systems above.

iSpring FA15 Alkaline Water Filter

iSpring FA15 is a high-quality inline alkaline water filter and it comes in two versions, a new upgraded version, and an older version.

In this review, we look at the new iSpring FA15 version which comes with a few upgrades that makes it much better than its older version and most other alkaline water filters in the market today.

The first thing that makes this upgraded iSpring FA15 model stand out is the set of media that it comes with. It’s a 3-lay mineralization filter cartridge made up of red mineral stone, calcite, and courses.

The purified RO water first goes through the mineral stone side (red), then moves through the calcite media side (white/clear) where it exits towards the RO faucet.

As the RO water passes through the filter, the three media restore back the lost minerals which include calcium, potassium, magnesium, and sodium ions which in turn improve the pH level of the RO water.

The filter is capable of raising the pH level by 0.5 to 1.2 which makes it quite effective for use in areas where the source water has a very low pH level.

All the media and material used in making this iSpring FA15 filter are all-natural and FDA grade hence they are not only safe. They will leave no residues behind or further contaminate the water as the synthetic alkaline filters do.

The updated FA15 alkaline filter can work with any under-sink RO system. Unlike the older version, this one features a very secure push-fit quick connection for quick installation or replacement at the end of your RO system as the last stage.

You just need to screw the push-in connector on each end then attach a ¼” water tube on both sides. However, the flow direction arrow is not that well labeled like in the older FA15 alkaline filter but it can be installed in either direction.

The filter does not affect the normal flow rate of water and considering that it’s an inline filter, you won’t need to buy housing. It can last from 6 to 8 months depending on the pH level of your RO water.

Aquasana AQ-RO3-RM Remineralizer Filter

In the second position, we have the Aquasana AQ-RO3-RM which is another quality remineralizing filter that’s built to effectively restore back minerals stripped from water by the RO filtration process.

This remineralizing cartridge is made out of ground limestone and flow may which are the media responsible for adding the lost minerals back into RO water as it passes through it.

The filter is capable of putting back healthy amounts of magnesium, calcium, and potassium into purified water, a mixture which helps balance the pH levels of the RO water.

It can raise the pH to near 7.0 which is an ideal level that ensures healthy drinking water that tastes much better than pure RO water.

Installing the Aquasana AQ-RO3-RM is also pretty straightforward. It features a unique compression fitting that allows you to easily hook it directly in line after the post-filter in the RO system. 

It uses 3/8” tubing, so you will have to get a 3/8” to ¼” reducer if your system uses a ¼” hose. The filter also offers a decent life service as it can last up to 1 year before requiring replacement.

The only unfortunate thing is that it’s not quite ideal for use with RO systems from other brands. It’s designed to work best with Aquasana RO systems.  


HIKINS is a reputable high-tech manufacturer of water filtration systems as well as air purifiers. Their PH+ alkaline filter is one of the best models in the market and this is attributed to its efficiency with regards to remineralizing RO water.

This high-performance filter is made up of natural mineral stone and calcite media that restore back the essential minerals to pure water.

The filter adds back calcium, potassium, magnesium, and potassium ions into the water which was removed while purifying the water.

This mineral mixture can improve the pH level of the RO water to around 7.5 to 8.5 which helps balance your water hence giving you a much healthier and safer home drinking water. Another commendable thing about this HIKINS alkaline filter is that it’s designed to work with a wide range of systems. It’s fully compatible with any under sink RO system.

It can work with APEC, iSpring, Express Water, and other systems. The installation is very simple and the package comes with two connector fittings alongside the alkaline filter. In general, if you are looking for a universal alkaline filter that can work with any RO system, then the HIKINS PH+ alkaline filter is worth considering. It can last from 3 to 6 months based on the quality of your feed water.

The filter will give you 1 year of service before changing out. It’s certainly a great add-on to any RO system for those looking to boost the mineral content and pH of their RO water.

Water Filter Tec Alkaline Filter

This Water Filter Tec model is a fully packed alkaline water filter cartridge that features 5 different media that restore back all the essential minerals into the purified water after going through the reverse osmosis filtration process.

The Water Filter Tec filter offers the ultimate natural blend of ionically activated stones to turn pure water into good alkaline water.

It’s a five in one alkaline filter consisting of a mixture of alkaline calcite, bioceramic, tourmaline, mineral stone, and ORP ball.

The first mineral stone, alkaline calcite is very effective at boosting the RO water pH to a higher level than regular alkaline filters. It can raise the pH from as low as 5.5 to 8 with only small contact.

The tourmaline stones are yet another precious stones that are included in this Water Filter Tec alkaline filter. It releases 0.06mAbiolectectricity into the RO water and generates negative ions.

It also electrolyzes the RO water as well as narrows the molecular beams. All these accounts for numerous benefits you will get from drinking the water remineralized by this alkaline filter which includes detoxification, reducing the lactic acids, liver and kidney support, and toxic metal elimination.

The fourth minerals in the lineup are the mineral stones which equally aid in activating water molecules within the body cells and blood to improve blood circulation.

ORP balls are the last media in this filter and they further help to clean the RO water by reducing its Oxidant Reduction Potential which not only helps to maintain healthy body cells but also boosts metabolism and immune system.

In short, the Water Filter Tec filter is one of the best alkaline filters out there that offers a perfect blend of natural alkaline contents.

It will effectively balance the pH of your RO water and on top of that add all the essential mineral supplements into it and make it much tastier water than your regular RO water. You also get an all-around, anti-oxidation effect and more oxygen than in normal RO water.

The installation has also been simplified for you as the filter comes with quick connect fittings plus filter clips that make connection it quick and easy.

It uses ¼” fittings, so you will need a 3/8” adapter if your system uses 3/8” tubes. Depending on the quality of your source water, it can give you a service life of around 6 to 12 months or 4000L.

Geekpure C-R05-MF

The sixth spot in our list is taken by the Geekpure C-RO5-MF mineral filter. This is a pretty decent alkaline filter that’s built nothing but what the work is intended for which is to balance the pH level of the water and add back essential minerals.
