CuZn UC-200 Review


What is great for under sink filtration systems is that they don’t produce wastewater. You don’t need much space under your sink to place them. And the CuZn UC-200 Under Counter Water Filter shows they can be efficient and convenient enough so you don’t need to buy a reverse osmosis system.


Made in the USA, this product is one of the highest-rated under sink filtration systems available. What makes it so popular is its fair price, high capacity, and super efficiency. Along with that, it has a definitely long-lasting filter. It can produce 50 000 gallons of water what for most people would mean using the system for nearly 5 years.

Above all, it is very easy to install and needs almost no maintenance. You can’t ask for more.


CuZn UC-200 Under Counter Water FilterThe CuZn UC-200 is a 3 stage filtration system with a micro sediment membrane. It also has KDF-55 & Coconut Shell Carbon. The KDF-55 is simply a way to keep your water safe from the harmful chemicals found in pipes. We are talking about water-soluble lead, mercury, nickel, chromium, and other dissolved metals. It also controls the build-up of bacteria.

On the other hand, the coconut shell carbon filtration is bacteriostatic and not responsive to mold or bacteria growth. Another great thing about this system is that the process purifies your water while it’s not removing the healthy hardness minerals. What it removes is a wide range of contaminants including but not limited to chlorine, water-soluble cation heavy metals, herbicides, pesticides, sediment, algae, molds, bad taste, odors and other. In other words – everything that causes your water to taste different and affects the quality of your water.

We should note here that this product doesn’t reduce TDS readings, so a PPM or TDS meter will be of no use to you. To Monitor The UC-200 you should utilize DPD#1 Chlorine Test Strips and replace it when chlorine breakthrough is identified.

Another thing that you want to know is that the device is designed to work with city water and not well water. The flow rate of the system is 2 GPM.


The UC-200 comes with all you need to install it. It is very simple, yet does its job wonderfully. The set includes the KDF-55 filtration media and the acid-washed catalytic coconut shell carbon.

Installation and maintenance

This system is super easy to install. You would not need anything more than an adjustable wrench to put it under your sink. You will need to disconnect the cold water line and simply connect it to the UC-200. Then you connect the stainless steel hose, which is included in the set, to the cold water valve and the inlet of the system. That is pretty much all.

There is video instruction, provided by the manufacturer. You can easily find it on their website. An additional thing is that the company will provide all extra parts or adapters if you need any. For any unusual plumbing systems, you can always call tech support.

No maintenance is needed. And when 50 000 gallons of water is filtered or in 5 years you simply change the system. With the easy as you first install it.
