CuZn UC-200 Under Counter Water Filter Reviews

The CuZn UC-200 is one of the best top rated under sink water filters on the market. What makes it highly popular is its impressive filtration features, advanced design, quality, super efficiency and convenience all at a relatively fair price. More importantly, it has the most long-lasting filter offering the highest capacity on our list.

Filtration Performance

The CuZn UC-200 model utilizes a 3-stage filtration process which consists of a micro sediment membrane, KDF-55 filtration media, and virgin acid washed catalytic carbon filtration media made from coconut shell carbon.

This impressive filtration process and advanced materials remove a wide range of contaminants from your water both inorganic and organic.

The first media which is the micro sediment membrane helps clear out sediments and tiny particles from the water.

The KDF-55 media and catalytic coconut shell carbon combination, on the other hand, work effectively to remove many different kinds of harmful chemical contaminants found in the water and the pipes.

The first main items they eliminate are chlorine, chloramines and chlorine byproducts like chloromethanes and bromoform. The robust catalytic coconut shell carbon filtration media is also capable of reducing most types of pharmaceutical and perfluorinated (PFOA) compounds.

It can reduce Glyphosate too and several volatile organic compounds found in municipal water.  In short, it will basically remove almost all chemical contaminants that often affect the taste, odor, and quality of water.

The UC-200 KDF-55 filtration media stage, in particular, does a great job of reducing up to 98% of all the water-soluble cation heavy metals like lead, chromium, nickel, mercury, cadmium and other dissolved metals.

Another commendable thing about this unit’s filtration process is that it purifies the water selectively. It will not remove the beneficial hardness minerals such as calcium and magnesium. Therefore, you get clean filtered water with the healthy minerals present.

Bacteriostatic Filtration System

One of the best features of the CuZn UC-200 model is its bacterial growth prevention. It is bacteriostatic which means bacteria can’t grow within the unit like is the case with carbon only filters which are susceptible to building up of microorganisms over time when not changed frequently.

The inclusion of the KDF-55 media helps create a bacteriostatic environment in the unit which limits any possibility of microorganism growth and also kills any bacteria present in the water.

By direct electrochemical contact and flash formation of hydrogen peroxide and hydroxyl radicals, this KDF redox media causes cellular damage to the microorganism lingering inside the unit by disrupting their ability to function thereby destroying them completely.

As such, there’s almost zero chance of bacteria, mold, and algae building up within the system thereby preventing any further contamination of the water and the potential spread of water-borne diseases.

Capacity and Efficiency

The CuZn UC-200 offers an incredibly high capacity as it is able to filter a maximum of 50,000 gallons of water on demand throughout its lifespan. Basically, you will be using it for nearly 5 years or even longer if it’s only for drinking water and cooking.

The unit is also built to withstand a great deal of pressure. It’s capable of handling up to 130 psi operating pressure which is a big bonus considering that the city water pressure in most homes is around 60 psi.

The flow rate is equally high as the system can produce about 2 gallons of filtered water per minute and the best part is no wastewater is generated in the process, so it’s 100% water efficient.

Installation and Maintenance

Installing this CuZn system is super easy. All the necessary parts required to hook it up under your home or office sink are provided.

The unit is designed to filter cold water from the municipal/city water treatment supplies alone. It’s not recommended for use with private well water suppliers. 

A separate dedicated faucet for the filtered water is not required since it can work with an existing cold water faucet. However, if you prefer to install it, the manufacturer provides a complementary alternative installation kit for the dedicated filtered water faucet setup upon request at no additional cost.

Almost no maintenance is needed because the filter it uses is long-lasting. You will only have to change the system after around 5 years and the process is simple as the first time you install it.

One downside we noted with this unit is that it does not consistently reduce a high percentage of fluoride. It reduces the levels by just 20 to 30% on average.

It’s also not the right choice for dealing with excessively hard water issues brought about by extremely high mineral content since most of these minerals are allowed to pass through the filter.

Overall, this CuZn UC-200 model is a top under sink water filter that offers reliable general purification of municipal water issues. If you want a more basic yet effective low maintenance and long-lasting water filtration system, then this an option worth investing in.

Pros

  • Removes a wide range of organic and inorganic contaminants
  • Kills and restricts the growth of bacteria and mold within the system
  • Incredibly high capacity (50,000 gallons) and flow rate (2 GPM)
  • 100% efficient with zero wastewater generation
  • Setting it up is a breeze and almost no maintenance needed
  • Long-lasting filter offering up to 5 years of service
  • Comes with a 5-year limited warranty

Cons

  • The “in” and “out” flow not indicated on the unit

Frizzlife MK99 1-Stage Under Sink Water Filter Reviews

The Frizzlife MK99 takes the second spot on our list and like CuZn UC-200 model above, this is an under sink water filter that has earned high ratings from many different users due to its fantastic performance and water flow production after installation.

Filtration Performance

The filtration system of the MK99 is a 2-stage process involving a sediment filter and an advanced carbon filter that work together to effectively eliminate contaminants in the water.

The 1st stage employs a pleated polypropylene (PP) sediment filter with 5-micron precision and it clears out particles and sediments such as silt, sand, rust, and scales from the water.

The filter is 100% constructed using polypropylene media hence it won’t degrade even when exposed to many different chemicals.

On top of that, it’s made up of multiple membrane layers that are thermally bonded together, and as such, it provides consistent pore sizes and a much better dirt-rejection capacity than other sediment filters.

The 2nd stage consists of a highly effective carbon block filter which does the heavy lifting removing more than 58 contaminants commonly found in unfiltered water.

This advanced carbon filtration media with 0.5-micron precision which is by far smaller than most other similar under sink filters can remove up to 99.99% of chlorine, lead, chloramines and other chemical contaminants. In the same process, unpleasant tastes and odors are also cleared out of the water.

Volatile organic compounds, carcinogens, chromium 6 and heavy metals like mercury are all removed by this filter too. If you are looking for a unit that’s good at clearing out heavy metals, then this will make an excellent choice.

A key feature we also liked about the MK99 is that it’s intentionally designed such that it leaves the essential minerals intact. Therefore, calcium, potassium, magnesium, and sodium which are all important building blocks for achieving a healthy body will remain in the water while it strips the other contaminants.

Capacity and Efficiency

The filtration capacity of this MK99 is not the highest out there but it’s pretty decent. It offers a filtration capacity of 5000 gallons for chlorine and 1000 gallons for lead reduction.

The overall capacity is 1,600 gallons which means it can serve you for up to 2 years depending on your feed water quality and daily usage. However, Frizzlife recommends changing the filter after every 6 to 8 months to ensure better filtration throughout.

The unit is generally super-efficient like most other under sink water filters since it produces no wastewater. Furthermore, although it delivers water on demand, the flow rate is quite high.

It can deliver 1.5 gallons of filtered water per minute at 40 psi and up to 2 gallons at the standard municipal water pressure of 60 psi, so no long waiting times when filling a large container.

Installation and Maintenance

Featuring the quick twist-in installation design, setting up this unit and replacing the filters is easy-peasy. It will take less than 5 minutes to install it and the package comes with all the supplies required to complete the installation including the system mount, tubing, and a plastic filter wrench.

The unit can fit either the 1/2” or 3/8” cold water line under your sink hence no extra adaptors needed and it connects directly to any standard faucet.

Alternatively, you can order one with a dedicated faucet if you prefer to have a separate dispenser for the filtered water but you will have to drill another hole in your sink to accommodate it.

As I mentioned earlier, the manufacturer recommends replacing the filter every 6 to 8 months. It’s not the longest lifespan but the good thing is that replacing the filters is really cost-effective.

Unlike other brands, the unit designed with the core filter cartridge placed inside the plastic housing. Therefore, you simply change the inner cartridge alone without tossing out the housing which cuts down the cost of replacing the filter periodically.

The filter head itself has a built-in shut off valve and this is a thoughtful addition that will allow you to carry out the filter cartridge replacement without having to turn off the water supply which is very convenient.

On the downside, besides the filter cartridge having a short lifespan, this model although is designed for use with only city water. It’s not for heavy-duty filtration needs like purifying totally untreated water from a well source.

With that said, the Frizzlife MK99 might not have the highest capacity, but it does provide an effective filtration system that’s capable of removing many contaminants and producing clean and better-tasting water.

Pros

  • Filters out contaminants down to 0.5 microns
  • Leaves essential minerals intact in the water
  • Decent filtration capacity of up to 1,600 gallons
  • Has a high flow rate of about 24 gallons per minute
  • Installation and filter replacement is quick and easy

Cons

  • Shorter filter life although much cheaper to replace than other brands
  • Designed to purify only city water

The SK99 is yet another under sink water filter model from Frizzlife that stands out on our list when it comes to filtering contaminants in municipal water. It’s a quality unit offering superb functionality and filtration ability that guarantees great results.

Filtration Performance

The Frizzlife SK99 is equipped with 3 stages of filtration comprising of a sediment filter and two carbon filters that provide high precision filtration of harmful contaminants. 

Stage 1 of the system is a pleated PP sediment filter cartridge and it delivers much better performance than conventional filter cartridges in removing sediments and particles from the water.

It has multiple layers on its surface that facilitate greater surface area and with 5-10 filtration precision, it will eliminate tiny to large particles present in the water including sand, silt, dirt and rust thereby ensuring better protection for the later 2 stages.

Stage 2 is made up of a carbon filter cartridge which serves as the initial filtration stage for most of the chemical contaminants. With a 3 to 5-micron precision, this filter performs well to significantly reduce the amount of chlorine, chloramine and other chemicals in the water.

It also removes volatile organic compounds (VOCs) as well as residual particles that may have made past the sediment filter.

At the final stage is the Frizzlife top-grade carbon block filter cartridge providing up to 0.5-micron filtration precision which is almost 10 times higher than many other brands as most of them with similar filters often have an average precision of 3 microns.

This remarkable contaminant removal performance allows the filter to clear out over 99.99% of lead, chlorine and the remaining VOCs and chloramine.

The filter will also remove fluoride, cysts and other heavy metals like arsenic, mercury, and cadmium thereby producing cleaner water with no unpleasant odor, taste or color.

Same to the Frizzlife MK99 model, the filtration process of this SK99 system does not touch the essential minerals. Calcium, potassium, magnesium, sodium, and phosphorus are some of the health-benefiting minerals it leaves behind which means the water that comes out is both clean and healthy with a fresh, natural taste.

Capacity and Efficiency

According to Frizzlife, they have not provided the exact capacity for this model because of the variation in the level of usage and quality of water amongst different users.

Nonetheless, you can expect to get a decent capacity plus the flow rate is fairly high. It’s rated to produce 1.7 gallons per minute but it can go up to 2 GPM at 60 psi feed water pressure and there’s zero water wastage, so it’s highly efficient too.

Installation and Maintenance

Even if you are completely inexperienced, installing the SK99 will pose no challenge whatsoever. It’s a DIY installation system that requires just following the straightforward instructions provided to set it up within a few minutes and it connects to the existing faucet.

It will fit both the 3/8” and ½” water line.  A housing wrench and everything you need to install it is provided as well as two extra 3/8” to ½” converters. Furthermore, the system utilizes the twist-in filter design which allows you to change filter cartridges effortlessly.

Only the inside filter cartridges are replaced, not the filter housing which is a notable feature of most of Frizzlife under sink water filters and it means you will benefit from lower costs with regards to filter replacement.  

The service life of the sediment filter is 6 to 12 months while that of the 2nd stage carbon filter is 8 to 12 months. For the last carbon filter, you will need to change it every 12 to 18 months.

Compared to many 3-stage under sink water filters out there, the exceptional performance and overall quality of this Frizzlife SK99 unit undoubtedly make it one of the best models. It’s a unit you can rely on to give you clean drinking water without any fuss.

APEC Water WFS-1000 Under-Sink Water Filter Reviews

APEC Water is a reputable manufacturer of water filtration systems with a long history of producing quality products. Their WFS-1000 under sink water filter system does not disappoint either as it’s amongst their top products with much positive reception. 

It’s a basic under sink water filter designed purposely for removing chemical contaminants from the water, especially chlorine. If your water is already good but you just want to refine it and protect yourself against any potential contamination, then this is a nice option to check out.

Filtration Performance

The APEC Water WFS-1000 has 3 filtration stages consisting of a sediment filter and two carbon block filters which together provide a commendable filtration performance.

At the 1st stage is the high-grade 10″ polypropylene sediment filter which extracts as many sediments as possible from the water including dust, rust, silt, and other tiny and major particles in order to protect and maintain the filtering ability of the next stages.

The water then goes through an extruded carbon block filter in the 2nd stage which is typically made up of activated carbon particles fused together into a single block.

This serves as the first point of carbon filtration where a majority of the chlorine, VOCs and other chemical contaminants like pharmaceuticals, pesticides, and herbicides are initially removed from the water. Unwanted tastes, odors, cloudiness and residual sediments are cleared out as well at this stage.

The 3rd stage has the same extruded carbon filter which performs the final refining by further removing the remaining chlorine, odor, tastes, color, cloudiness and other chemicals.

The use of these dual carbon filters significantly boosts the filtration performance of the unit allowing it to get rid of almost all the chlorine, tastes and VOCs from the water, and also organic chemicals.

The mineral composition and alkalinity of the water do not change throughout the filtration process. The result is mineral-rich water that’s clean, looks clear and tastes fresh.

Capacity and Efficiency

APEC has not specified the total gallon rating for this WFS-1000 model but if we have to give an estimate, it will process more than 1,000 gallons of water before needing replacement.  

For a lot of households with regular normal usage, this means it’s likely to last 1 to 2 years provided your water is not highly contaminated. It’s a decent lifespan compared to most similar systems.

Although the unit uses three filtration stages, you won’t notice a big change in the water flow. It has a maximum flow rate of 1.6 gallons per minute, thereby it will filter the water quickly and provide a continuous on-demand supply of clean purified water to your faucet. Furthermore, no water is wasted, so your monthly water cost won’t change much.

Installation and Maintenance

The WFS-1000 comes fully assembled for installation. What’s required is to mount it in the desired location, insert the filter cartridges, and connect the tubing.

The challenging part may be to install the faucet as it’s designed to work with a separate dedicated faucet for dispensing the filtered water.

The package comes with 100% lead-free chrome faucet, hence if there’s no pre-made hole in your kitchen counter, you might have to drill one to install this faucet.

The unit falls in the medium to large size end and as such, it should fit under most standard kitchen cabinets. If it’s small, then you will have to adjust some stuff to create room for it.  

There’s little work to do with regard to maintenance because it’s just replacing the filters at least after every 12 months and it’s equally an easy and quick process.

Now one of the setbacks of this unit is that despite having dual activated carbon filters, it still cannot eliminate chloramine from water which might be a concern for those living in cities that utilize chloramine to treat water instead of chlorine.

According to APEC, the filter will also not remove fluoride, bacteria and heavy metals like lead and arsenic. Total dissolved solids as well pass right through the filters. What this generally means is that it’s not ideal at all for filtering well water.

In conclusion, as long as you are seeking to purify only municipal water that’s treated with chlorine, the APEC WFS-1000 will be a better fit for you. It will serve you for long and deliver the water quality you desire.

Pros

  • Designed for removal of sediments and chemical contaminants
  • Eliminates unpleasant tastes, odors and water cloudiness
  • Doesn’t interfere with essential minerals or water alkalinity
  • Can process more than 1,000 gallons of water before replacement
  • Installation is fairly easy as well as changing the filters
  • Comes with a 1-year limited warranty and a dedicated standard faucet

Cons

  • It’s not able to filter out chloramine, fluoride and heavy metals
  • Not the most compact under sink water filter system
