You’re here looking for a water filter means you are worrying about what’s present in the water after a long journey through the pipeline to your faucet.

Or, you just always smell chlorine whenever you take a sip from a tap (faucet), even after you boil the water…

… and you hate it.

Installing a water filter system is the solution.

But choosing the right filter system is not easy for everyone, especially when you are shopping online.

That’s the reason why we created this ultimate guide.

In this guide, you will learn about your drinking water, you can decide what type of filter you want to have, and what price range you can afford.

In short, you will find the answer to your query: “what is the best water filter system for me?”.

Know your Water

We drink and cook with water from kitchen sink faucets. But few people know about the type of water they are using. Even fewer know what’s present in the water.

Well Water

If you are using water from a well, you should know that it contains many elements such as metals and dissolved salts.

Their concentrations pose a health concern.

Geologists recently checked wells nationwide for two-dozen trace elements. They found trace elements in most of them.

Thirteen percent had one or more elements surpassing federal health recommendations (Scientific American, 2011).

Tap Water

You can feel safe drinking tap water in most parts of the United States.

However, some of it contains chemicals such as chlorine and pesticide residues.

Some states also have to contend with high levels of nitrates, lead, and arsenic.

And who can forget the water crisis in Flint, MI? Cost-cutting measures in 2014 led to the contamination of the city’s water supply (CNN, 2018).

Now you may have an idea about the type of water you are using and what you have in the water.

Hard Water

Water is soft as it leaves the heavens in the form of rain, which means it is free of contaminants.

But as it falls, it picks up impurities such as carbon dioxide in the air. It also dissolves magnesium salts and calcium as it penetrates through the earth.

These elements remain as it runs off into lakes or rivers and gathers in wells or reservoirs.

The US Geological Survey calculates that 89.3 percent of homes have hard water (The Salt Institute, 2013).

The belt from Kansas and Texas to Southern California has the hardest water in the nation.


If you are living near the seaside and you are using water from a well, your water may contain salt.

Saltwater is corrosive, and it ruins appliances.

The taste of saltwater is also undesirable, leading many to buy bottled water.

You may also be ready to install a water filter.

But keep reading.

We still have a lot more useful info in the short form right here. Read it first before you go digging on the Internet and get confused.

Demand for Filtration

First, you need to know your needs.

Do you want a commercial water filter system or one for home use?

Water Filters for Home Use

Most people buy a home using a water filter because they care about the health and quality of life of their family.

Water filter and filtration technologies are growing fast. Thus, you will see many types of filtration systems on the market.

The water is of a much higher quality as the filter removes salt, iron, fluoride, chlorine, and bacteria. It also balances the pH levels and adds alkaline and flavor.

You can buy a whole house filter system, a countertop or under-sink model, or a dispenser. You can even get a pitcher with a filter within a reasonable price range.

Commercial/Industrial Water Filters

Restaurants, buildings, and hotels often use commercial water filter systems. You can also find them in schools, hospitals, and factories.

A commercial water filter system can filter most contaminants. These systems filter large amounts of water to provide for many people.

The cost of a commercial filter system is prohibitive, but the result is worth it.

Usually, municipalities use this type of filter for well water or saltwater. Factories also use them to clean water for production.

You may ask: “What does a water filter system do?”

Let’s take a glance at the water filter functions before we go through all the types of home-use filters one by one.

Functions of Water Filters

Water filters use two different methods to remove impurities.

Some use physical filtration and strain the water to remove larger particles.

The other process is chemical filtration. With this method, the water passes through an active material such as charcoal.

These systems must act as filters, softeners, and purifiers.

Water Filters & Purifiers

A water filter is a system that can remove most contaminants to provide a better quality of water.

Viruses are too minuscule for most filters to catch. Water purifiers fight these pathogens.

Like water filters, purifiers include an internal cartridge or element with microscopic pores. These pores grab bacteria, protozoa, and debris. They also use chemicals such as iodine to kill viruses.

There are many options to choose from, such as a pump, gravity, ultraviolet, and bottles. Each type has its pros and cons.

Let’s look at the different water filter types, to decide which one is for you.

Water Softeners

Water softeners are a type of filter that softens water by removing or neutralizing minerals. These minerals cause scale and make water hard (known as hard water).

The filtration system treats hard water by using ion exchange and salt resins. This process removes magnesium and calcium hardness.

Most of the water softeners are designed for whole-house uses, not specific for under sink or point-of-use.

There are 2 most popular types of water softeners: salt-based and salt-free

Salt-based Water Softeners

Salt-based water softeners remove minerals like magnesium & calcium to make your hard water “be soft”.

This type of water softener also reduces limescale in the water, limescale is a  chalky off-white crust that stains on surfaces or lurks inside your kettle after a while of boiling water.

Using and maintaining a salt-based water softener will cost you a little bit more than most other water filters.

Salt-free Water Softeners or Water Descalers

In fact, these options are known as water conditioners or descalers (Electric or magnetic water descalers), but they are called softeners even if they don’t make the water softer (less than 1 grain/gallon).

With a salt-free water softener, contaminants like magnesium and calcium will not be completely removed but neutralized to prevent limescale deposits from hard water.

You may spot limescale build-up from your water but Salt-free Water Softeners are the best options for people who don’t want to add sodium and other chemicals to their water.

One pro of this type of water softener is low installation and maintenance cost compare to salt-based systems.

Whole House Water Filtration

Filtering your water for home use is more a necessity than a choice nowadays if you care about your health. It’s not only for drinking water but also for showering or washing clothes.

Water with contaminants can leave stains on clothes (especially whites) after a while, and hard water destroys pipes and sewer systems over time.

Another way you can tell if your water has contaminants is by lather. If the lather from shampoo or soap disappears fast, your water may have contaminants.

Also, as we have seen, there are lots of other things to deal with besides hard water when your source is a well. There’s dirt, chlorine, pesticides, and sediments, and these too can cause problems.

The best thing to do is to decontaminate the water you use at home. In that way, you won’t have to put up with these complications.

That’s the reason why we have whole house water filter systems.

So, who should use a whole house filter system?

The answer is anyone, especially if your water is hard or sourced from a well.

There are whole house water filters designed for wells. They reduce iron, catch sediment, soften the water, and remove the sulfur smell. They also reduce the levels of bacteria growth, chlorine, pesticides, and herbicides.

A typical whole house water filter system removes 95-97% of VOCs and chlorine. It also removes sediment and other contaminants without wasting water.

Some of them do not reduce Total Dissolved Solids (TDS). But this point is not a significant factor. Reverse osmosis makes your water clean enough. The RO process makes it much better for drinking and general home use.

As for drinking water quality, you can use a Reverse Osmosis system as a whole house water filter. And it is, without doubt, the best option for this purpose.

The downside of a RO system for use as a whole house filter is the amount of GDP and water pressure. You may need an extra booster pump to gain water pressure.

Filter Material

The primary material inside a whole house water filter is charcoal. This material is also known as activated carbon.

These materials help cleanse water by capturing impurities.


The typical whole house water filter system costs more than a RO system.

You can find some under $200, but most of them go for more than $500. The prices even go into the thousands.

Most of the RO systems cost on average about $200 – $300.

Both standard whole house filters and RO will have long-term maintenance costs.


Of course, you must install the whole house filter system on the main pipeline. Once it’s connected, you will get filtered water from any faucet in your house.

You have two options for installing your reverse osmosis (whole house) filtration system. You can do it yourself or hire a professional.

People often have a plumber install their water treatment systems. They may also use an electrician to do the wiring.

Most of the filtration systems available online have step-by-step instructions. They are easy to install.

You won’t need contractors with special training: a regular handyman plumber will do.

Cartridge Replacement

You should replace your whole house water filter cartridges every three months. You can do it yourself. First, turn the water supply off. Next, relieve the water pressure on the lines before unscrewing the holder for the filter. Remove the old filter and clean the inside of the holder with paper towels. Put in the new one and screw the holder back in place.

Top Brands For a Good Whole House Water Filter System


Aquasana water filter systems remove up to 97 percent of chlorine or chloramines from your water. These chemicals take a toll on your plumbing system, and they’re also not good for you. Aquasana systems come equipped with Claryum filters. These filters remove all the things you can’t see, taste, or smell. Included in the list are undesirables like chromium and fluoride.


Culligan offers several different whole house filtration solutions. They have filters for houses with well water. They also have filtration systems to deal with arsenic, acid water, and discoloration problems. Culligan also offers Iron-Cleer and Sulfur-Cleer® filters. Both these filters work as their names suggest.


GE Appliances has developed an extensive collection of filtration products. Buyers have a range of options from which to choose. One of the advantages is that their filters are easy to replace and cost only about $10 ($50 for high-end models). GE has rigorous testing standards. Third parties also certify their products. This process ensures that customers are getting the best deal.


Whirlpool lets you experience the benefits of filtered water with whole-house systems. These systems do not need maintenance. They also come equipped with FilterSense technology. This technology flushes the internal filter and cleans and drains it every 14 days. The filtration system is also NSF-certified to reduce the chlorine smell and taste of your water.

Pros & Cons of Whole House Water Filters

The biggest pro of these filters is their health benefits. They filter out dangerous concentrations of sediments, chlorine, and chemicals.

The filters have a long life – five to ten years is typical. Whole house systems also need little or no maintenance.

The filters last long and upkeep is negligible. Thus, a whole house filter is a cost-effective solution.

The disadvantage is that you cannot fine-tune your water filtration (Point-of-use filters allow you to take a more targeted approach. You can install these filters under sinks, in showers, or as freestanding units in the kitchen).

You might have to get a plumber to put in your whole house water filter. It requires more plumbing skills than installing a simple under-sink or countertop filter.

Under-Sink Water Filter

Under-sink variety can filter lots of water. They deprive you of space from the cupboard underneath the sink, they don’t clutter the counter.

You may have to drill a hole through the countertop or sink for the dispenser. You may also have to make other specialized plumbing adjustments.

Inline Under Sink Filters

You can use some inline filters for more than one appliance.

For example, you might be able to connect your filtration system to your fridge, water cooler, and kitchen tap. Inline filters are also an inexpensive option.

Most have quick-connect or push fittings that allow a seamless replacement process. They are also known for their durability.

On the downside, inline water filters are not reusable after the end of their service life.

You will have to replace it in full when that time comes. This replacement does not amount to high annual costs, given the durability and low cost of the filter.

Another con is that you must have some basic plumbing knowledge. Installing your inline water filter is technical, so you might have to hire a plumber if it’s too much for you.

Reverse Osmosis System (RO)

A reverse osmosis system is the best type of under-sink water filter available. These units produce pure, great-tasting water at a very reasonable cost.

They are automatic and trouble-free. They run on water pressure, not electricity.

They remove solids like sodium. They also remove organic impurities, including chlorine and its byproducts.

Reverse osmosis occurs when water moves across a membrane. The water must run against the normal concentration gradient for RO to occur.

To illustrate, imagine a membrane separating freshwater from orange juice. With normal osmosis, the freshwater will cross the membrane to dilute the juice. Reverse osmosis forces the water content from the juice to cross over to the freshwater side.

You can pay as little as $70 for an inline reverse osmosis water filtration system. The better-quality brands cost a few hundred dollars (between $200 and $400).

You’ve got a few crucial factors to consider when looking for the right reverse osmosis system.

One of the first questions you’ll have to ask yourself is how much you’re willing to spend.

The space you have available for your filter is also an important consideration.

Another factor is how much water the RO system can filter.

Other factors are effectiveness, ease of installation, and ease of use.

Number of Stages

A reverse osmosis system has between three and seven stages. True reverse osmosis begins when the water gets through the RO membrane during the third stage, the RO membrane removes most of the contaminants that are present in the water including lead, fluoride, and chromium. The first 2 stages remove sediments and chloride to protect the RO membrane while the states 4th, 5th, 6th, and 7th will polish the water, add the necessary minerals, or kill the remaining bacteria and viruses with a UV light.

The most popular RO system is the five-stage model.

Normal or Full Contact?

You should also think about whether you should get a standard filter with separate filter cartridges and housings. The other option is to get one that uses “full contact” technology. A full contact filter circulates pure water through the re-mineralization filter. It does this circulation twice to restore minerals.

Gallons Per Day

The makers of RO units state the amount of water they expect to produce in gallons per day (GPD). Several factors affect production. These factors include water temperature and pressure. They also include the condition of pre-filters and total dissolved solids.

  • The reverse osmosis process takes away most of the minerals from water. You can counter this with a six-stage filter, which remineralizes water.
  • The purification process uses a lot of water. Your filter flushes about 20 gallons of water down the drain for every gallon it produces.
  • RO systems take a long time to filter water.
  • Reverse osmosis filters are costly.

Point Of Use Water Filters

Countertop Water Filter

Want a convenient source of high-quality water in the remote areas of your home? A good countertop filter can be your primary source of drinking water, even when you’re away from the kitchen. Another use is as a portable filter for travel. Several options are available, including the ubiquitous reverse osmosis type.

Faucet Filter

As its name suggests, you mount this type of filter on your kitchen faucet. The water first passes through a non-woven screen around the filter. This screen traps sediments like dirt and sand. Next, the water passes through a compressed block of zeolite and carbon. These elements remove chemicals such as chlorine. RO faucet filters use a combination of carbon and sediment to remove a wide range of pollutants.

Pur is superior to Brita when it comes to getting rid of sediments and chemicals. Only Pur is guaranteed to remove cryptosporidium and giardia from the water. According to Consumer Reports, people prefer the taste of Pur over Brita. They conducted blind tests, and most of the participants showed a preference for Pur. One point on which Brita comes out on top is the speed with which its filters work.


  • Low initial cost
  • Ability to shift between filtered and unfiltered water
  • Easy to install
  •  Ideal for cooking and drinking


  • Susceptible to leaks
  • Some filters clog easily
  • May not fit on all faucets
  • Decreases flow rate
  • The homeowner must change the filter every couple of months

Water Dispenser

Water dispensers have become office staples, but they’re great for use at home too. They’re a pro for the environment because their bottles are reusable. They’re also attractive to look at and come in a variety of shapes, sizes, and materials. It’s easy to find a unit that’s the perfect fit for your space. You also save money. Small disposable bottles are way more expensive than large reusable ones.

A water dispenser can be useful almost anywhere. Some offices prefer them because they provide employees and clients with convenient access to water. They are also common in homes where people do not have access to good drinking water from the tap, or for those who do not like the taste of tap water. Water dispensers can also be used in commercial settings.

You have several options if you’re looking for a home water dispenser. One of the most common types is the bottled water cooler. You will need to place a 5-gallon bottle at the top of this dispenser. If your space is tight, you can get a countertop water dispenser. Another common type is the point-of-use dispenser. This dispenser does not need a bottle, because it has a continuous water supply.

For awake, healthy, less fatigued employees, it’s a good idea for offices to install a water cooler. Like home dispensers, there are several options from which to choose. These options include point-of-use, countertops, and bottle dispensers. They are more sanitary than water fountains and are durable. Besides, they are eco-friendly.

Also available are commercial-grade water dispensers. These dispensers look like ordinary office coolers but often come with filtration systems. Some keep the bottle design, but they dispense water much faster than regular coolers.

Countertop/Tabletop Water Dispenser

These water coolers have small footprints and fit on a counter or tabletop. The compact design is big enough to house a compressor to cool the water. Some models have only one spigot for cold water, while others have two. Some models need a bottle while others are of the point-of-use variety. The advantage of countertop models is that they don’t take up valuable floor space.

Free-Standing Water Dispenser

Freestanding water dispensers are a bit more expensive than countertop models. They are a good option for spacious offices and homes. You will need an electrical outlet for both types. The water in a freestanding unit tends to get colder than that in a countertop model. It gets colder because the former has a larger compressor.

Hot & Cold (Water Cooler Dispenser)

Most of the water dispensers on the market are hot and cold models. The hot water is warm enough to make coffee or soup. That is why these appliances need an electrical outlet: to heat and cool the water. Some models have a room temperature option. However, it’s easy to achieve room-temperature water by mixing hot and cold together.

Bottled vs. Bottleless

Bottled dispensers are a convenient alternative to bottled water. You just have to flip the tab to access cold water. They are also cheaper and eco-friendly. The average person drinks 167 small bottles of water per year. Only 38 of these bottles will get recycled. The rest will end up in landfills. Bottled dispensers reduce landfill waste. They also give you immediate access to cold, clean water.

Bottleless water dispensers have even more advantages than their bottled counterparts. Although the bottles are reusable, at some point they will reach the end of their useful lives. Bottleless dispensers are better for the environment. Plus, you won’t have to strain to lift a heavy 5-gallon jug of water onto the machine!

In-the-door ice and water dispensers are now almost standard on refrigerators. Side-by-side and bottom-freezer models are most likely to have these dispensers. It’s nice to press a lever and have your glass filled with cold water and fresh ice. The water line on most dispensers runs through a built-in filter. This filter should capture impurities like lead and mercury. This filtration system should also improve the taste of your water.

Bottom-loading water coolers tuck the water bottle out of sight. It stays in the cabinet under the cooler. This type of cooler uses a pump to push the water up to the dispenser. Some dispensers feature an empty bottle indicator that will light up when it’s time to change the bottle. You can also buy one with a built-in nightlight that will make the water spouts visible in low light.

Water coolers and dispensers come in different sizes. Consider where you will place the cooler. You also need to take the size of your household or office into account. A five-gallon bottle might be too much if you live alone or if you have a small office. It might be better to get an 18-cup dispenser instead.

Water Dispenser Size

An 18-cup dispenser can fit in your fridge for quick, easy access to clean drinking water. These dispensers contain filters to get rid of contaminants in your water. This option is more affordable than bottled water and safer than drinking pure tap water.

3-gallon and 5-gallon water dispensers come in countertop and freestanding models. They occupy less than a square foot of space. Thus, you can place your cooler wherever it best serves your family or employees. You can also put it in the customer area of your business. They come in many different styles, so wherever you place your dispenser, it will fit your décor.

Mini water coolers come in many different designs. These coolers hold about 2.5 liters of water – equal to eight glasses. They are great for personal use at home or in the office. Some of the designs are appealing to children. For example, there are penguins, elephants, and TV characters like Hello Kitty. The water in mini dispensers is at room temperature.

Large water dispensers are the most common option for offices. Many homeowners buy them as well. These large coolers can be bottom-loading, but most of them have a gravity feed with the bottle placed on top. Large dispensers are also an excellent option for commercial use.


Plastic water coolers are very common, especially in offices and commercial spaces. It’s also common to see stainless steel. Homeowners seem to prefer stainless steel because it goes well with their kitchen décor. You can also find water dispensers made from materials such as glass and ceramics.

Plastic is by far the most prevalent material used for producing water dispensers. Most people are familiar with white plastic dispensers, with a blue spigot for cold water and a red one for hot. The plastic is durable and needs cleaning only about once per month. Though white is standard, other colors are available.

Many point-of-use dispensers are made of stainless steel. This material has several advantages over plastic. It goes better with the aesthetics of most spaces. It’s also more durable than plastic. The water is even better tasting, with no plasticky aftertaste.

Glass water dispensers are also available. Caterers often use these dispensers. They are also becoming more popular in hotel lobbies. This newfound popularity may be due to their aesthetic appeal. Glass dispensers are an excellent option for upscale houses or apartments.

The idea behind ceramic water dispensers (or crocks, as they are also called) is centuries old. People used ceramic goblets to keep their water cold in the nineteenth century. Even today, ceramic water dispensers are attractive alternatives to bottle coolers. Finding countertop and freestanding ceramic water dispensers available for sale is not always easy, but worth the search.

  • Provide easy access to fresh, chilled water
  • Also provide access to hot water on demand
  • Encourage people to drink water instead of sugary beverages


  • Most dispensers must have a supply of electricity to work
  • Some dispensers are made from cheap plastic. This defeats the purpose of drinking chemical-free water

Filter Pitcher

Water filter pitchers are great for removing the smell and taste of chlorine from your water. They can also get rid of other chemicals such as fluoride, and heavy metals like lead. Most pitchers are plastic, but stainless-steel options are also available. Pitchers are great for improving the taste of your water. They also remove harmful substances.


Filter pitchers remove chlorine and fluoride. But they also add alkaline, infuser, and ionizer. The makers of filter pitchers have thought of everything. They’ve even placed covers over the pouring spout. These caps ensure that particles from the rest of the fridge do not end up in your filtered water. Pitcher filters can fit in most refrigerators.


Water filter pitchers start at the 5-cup size. This size is manageable for even a child to pour and refill. It’s space-efficient, and perfect for small families. Some models feature a useful status indicator to tell you when you need to change your filter. The average household needs to change the filter on a 5-cup pitcher about once every two months.

Pitchers are also available in the 10-cup size. This larger size has all the features of the 5-cup pitcher but can serve more people. It’s excellent for large families and small offices. The 10-cup model also fits in most refrigerators. Choose a BPA-free model for the best results.

The largest water filter pitcher option is the 18-cup model. Despite their large size, they are space-efficient and fit in most refrigerators. Most models have a spigot for ease in dispensing water. Their flip-top lids make refilling a breeze. The 18-cup option holds 1.13 gallons of water and is also perfect for large families and small offices.

Slim water filter pitchers have all the features of regular pitchers. They remove impurities and chemicals, and they make your water taste lovely. Their advantage is their shape. They’re made to fit on one side of the fridge, freeing up the rest of the shelf for your other stuff. Or, you can store your slim pitcher on your refrigerator door. It’s a good option for people with full refrigerators, and it’s also very convenient.


Water filter pitchers come in several different materials. The most common are plastic, glass, and stainless steel. Each has its pros and cons. Below we discuss the merits of the different pitcher materials.

Most water filter pitchers are made from food-grade BPA-free plastic. Making sure your pitcher is BPA-free is essential. You don’t want to introduce carcinogens and other contaminants into your body.

Glass is an excellent option for water filter pitchers. It has a pleasing aesthetic, and it’s safer than plastic. Glass can also last a long time (once you don’t drop it). Buying a glass pitcher also ensures that your water does not have a plasticky aftertaste.

The aesthetic of the stainless-steel water filter is also pleasing. Like glass pitchers, they give you great-tasting water without the aftertaste. They also reduce chlorine taste and odor.

Refrigerator Water Filter

Setting up a good quality filter in your refrigerator is a cost-effective option. There is the extra advantage that your filtered water will be cold too. A good fridge water filter will remove the impurities from your ice or water. It will also give you fresh-tasting water dispensed straight from your fridge. The lifespan of refrigerator water filters is also much longer than that of pitchers.

Personal Water Filter

Water treatment is essential to maintaining your health when backpacking, hiking, or traveling. When buying, you should know the difference between a water filter and a purifier. Water filters strain out protozoans (such as Cryptosporidium) and bacteria (like E. coli). Water purifiers also fight viruses, which are too tiny for most filters to catch. Filters are usually enough for backpacking or hiking. Purifiers are excellent for travel to less-developed parts of the world.
