The CuZn UC-200 is one of the best 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.
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.
