The purification system comprises

° KD 55 filter media

°Catalytic carbon filter media

° micro sediment membrane

Micro sediment membrane :

Sediment membrane removes all visible solid dirt from your water which otherwise would clog your faucets. Removal of solid waste in the water at the first level of filtration protects the next media from the build up of dirt and dust.



KD filter media mainly reduces chlorine, heavy metals, and bacteria using redox reactions. This gold colored media is recyclable and can control the growth of bacteria and molds.


Catalytic carbon media contains activated carbon that helps remove odor and VOCs. Carbon media improves water smell and color so you get totally bottled water like looking water from your tap. This media has been tested to NSF standard 42 and 61. Industry-standard water filtration process gives better tasting water that is free from any health affecting substance.

NSF standard 42 :

These filters remove chlorine, taste, and odor from water and are used either under the sink or with a whole house filtration system.

NSF standard 61:

This certification makes sure the product is designed using high-quality food-grade material so no harmful elements will leach out of the system into water. This sets a standard for what material can be used for water portability and how safe it is.

With 20 more years of experience, cuZn has become a pro in manufacturing the best filter system for uninterrupted water supply to the whole family.

Installation process :

Filter performance testing :

This is not a fancy system with indicator lights or digital monitors so how to know about filter life or performance? Using chlorine test strips you can assess your water filtration system’s functioning. If you detect chlorine in your filtered water it’s time to replace the unit. Using sensitive test strips that can detect 0.25 or 0.5ppm chlorine water level you will earlier detect the need for replacement.

Drawbacks :

No unit is perfect. Every system lacks in one way or another. Until now we have listed all beneficial features of this filtration unit but it does have some lags which you should be aware of as well. What are the drawbacks of this filtration system? There are some but even yet the product is the best amount the options available and most positive reviewed by users.

Use only with municipal water:

Manufacturers have made it clear to use this system only with chlorine treated municipal water. So if you own a private well you’ll need to purchase a separate filter for that.

Can’t soften water:

Hard water stains clothes, sink, dishes, expensive appliances. Heavy mineral content dissolved in water is a major issue for many but the sad news is this unit can remove those excesses of minerals. As this filter system can’t soften water using a hard water supply will harm the filter system as minerals will be built up and hinder the filtration process so buying a water softener becomes necessary. But if your water supply doesn’t have hard water then it won’t be a concern for you.

Larger than expected :

Don’t be fooled by the images. The unit is heavy and larger than it appears in pictures. Installing this unit under your sink will be a tedious job for some especially elderly. Yet if someone installs this unit for you then you will face no more water issues for the next 5 years. This unit requires no maintenance like filter replacement or cleaning so you don’t need to worry about water quality deteriorating if you forget to clean the filter on time. After 5 years you need to replace the whole unit.

Not a TDS reducer :

You will get the same TDS reading with both filtered and unfiltered water why? Cause cuZn uc-200 purifies water without altering natural mineral balance so the healthy mineral content in your water supply remains undisturbed. Using TDS meters to judge the filter’s performance efficiency is not an apt criterion in the case of this filter system.  If you need a TDS reducer then you can look for other cuZn products.
