It’s an effective filter that removes contaminants and pollutants from the water and also reduces the taste of water to almost neutral providing us with natural tasting contaminant-free water.

This is one of the reasons why the majority of homeowners choose the CuZn UC-200 over the competitors. 

So if you are looking for a water filter for your home, you might want to take a closer look at this one and find out more reasons why it should clean your home’s water.

The installation process of the CuZn UC-200 filter is super simple and can be done by anyone with the use of an adjustable wrench tool.

You don’t need to hire a professional to install the UC-200 filter under the sink. 

The manufacturer explains the installation process and gives excellent customer support.

The filter comes with all the fittings you’ll need to hook up the unit to your water line.

There are only two faucets involved in the filter attachment, so there is no need to drill a hole for a separate faucet on the sink.

First, we need to open the cold-water line run, to make sure that all the media fines are removed and any air in the filtration system is purged.

Then we must determine the cold-water line and turn it off and disconnect the supply line.

The filter connects directly to the standard plumbing cold water line under your sink.

But if you’d prefer a filtered water-only faucet, they can modify the installation kit just for you.

If you have non-standard plumbing, contact customer support and they will send you the right installation kit, they’ll even make certain parts for you to make sure your filter fits and works.

This is great customer service and support provided by the manufacturer.

The only complaint customers have is about the size that is bigger than they expected and requires a bit more space to fit under the sink.


Once you install it, you are done thinking about it, if anything unexpected doesn’t happen.

You will need to change the cartridge in about 5 years or when 50 000 gallons of water go through the filter.

Replacing this model cartridge is easy, comparing to other filters where you have to open up the housing and remove the cartridge.

The cartridge is the main part of this model, so it is simple to replace it, you just remove the hoses that connect to it and connect them to a new cartridge.

But the CuZn UC-200 company doesn’t sell replacement cartridges only, so you will have to order the whole unit again. 

It’s more expensive than most filter replacements but when you consider it’s good for up to 5 years, it’s actually very affordable.

However, this is a long-lasting filter system, which makes it very affordable, when compared to other models that require more maintenance. 

Full replacement of the unit will cost you $120, but again that may only be needed after five years.


The UC-200 uses three stages of filtration to clean up the water and give it a fresh and pure taste. There are micro sediment membranes that prevent particles like rust, silt, sediment, and other heavy metals to pass at this stage. The coconut shell carbon filter eliminates the bad taste and odor from the water, organic contaminants, and chlorine, and the KDF-55 filtration media prevents bacterial growth and filters out inorganic contaminants. 

This is especially useful as the UC-200 is bacteriostatic and not susceptible to mold or bacteria.

If you are concerned about microbes, TDS, and chloramine and you want to remove them from the water you want to drink, this model is not performing well against them.


The CuZn UC-200 is certified to these standards to ensure its high performance

NSF standard 42: for removing substances like chlorine and sediment, meaning it is certified to enhance aesthetic qualities of water (appearance, smell, and taste) 

NSF standard 61: a standard that ensures materials and components used in water treatment products are high quality and safe.


The CuZn UC-200 filter is backed by a behemoth of 50,000 gallons of water, a 90-day trial period, and a 5-year pro-rated performance warranty.

That warranty is useful for getting a discount on another unit if your filter stops operating properly before hitting the 5-year mark.

Why should you have the Cuzn UC-200 at your home?

The CuZn UC-200 filtration system is an impressive product with many satisfied customers and a fantastic Amazon rating.

Customer service is easily one of the best parts about buying this water filter.

We love the easy installation process. Though it’s not as quick as setting up a faucet filter, you can still get it done in under an hour.

It’s great that the company includes all parts and fittings. 

If you encounter any problem installing or using your water filter, do not hesitate to contact them,  they will provide excellent support.

We love the filtering long-lasting performance. 

This is one of the best under-counter water filters for removing chlorine, chemicals, sediment, and heavy metals.

When to avoid the CuZn UC-200?

This model is larger of its size because of its capacity. This is a 5-year filter meaning the cartridge must be big enough to last that long.

If you don’t have enough free space to fit the CuZn UC-200, you should probably avoid this model.

It makes installation a bit tricky, but not impossible, as you might need someone to help you fit it properly under the sink.

If you live in one of the several cities that disinfect their water using chloramine, do not buy this under-counter water filter.

You also want to avoid using the CuZn UC-200 filter with untreated water, because the water might contain waterborne microbes, which the filter does not remove.

And the filter is not effective against TDS, so you better use a Reverse Osmosis filtration system against TDS.

Final Verdict

If you are looking for a long-lasting under-sink water filter we highly recommend the CuZn UC-200.

You will get a high-performance filter that is very effective in removing chlorine and other organic contaminants from the water and by improving the water taste. 

And you will be amazed by the manufacturer service that they are providing for their customers.
