The CuZn UC-200 is an easy-to-install under sink water filter that, according to the manufacturer, processes up to 50,000 gallons of water without needing replacement.
Sounds too good to be true?
Let’s explore the features of the CuZn UC-200 Under Counter Water Filter in detail. We’ll also discuss its not-so-fascinating side and decide if it’s worth a shot!
The CuZn UC-200 Under Counter Water Filter features three filtration stages combined in one cartridge:
The system features a flow rate of 2 gallons per minute, which is enough for an under sink filter, and a 50,000 gallons filtration capacity, which (as claimed) you can use for five years.
The CuZn UC-200 may not be the cheapest under sink filter out there, but it’s pretty affordable.
Also, the system is made in the USA. So we can assume that it was designed under strict quality control measures.
Besides, we love the simple installation process. You can easily DIY and save the costs of hiring a plumber.
There’s also the 5-year warranty that covers a wide range of issues as long as you use the filter correctly (5-year comprehensive pro-rated warranty).
Lastly, we like CuZn’s customer support base. If you have issues installing your filter, you can contact them through email, phone, or live chat, and they’ll help you figure out what you need. Not just that, they’ll also send a free kit containing everything you need to install your filter.
The CuZn UC-200 Under Counter Water Filter removes sediments, chlorine taste and odor, organic chemicals, and a few water-soluble heavy metals like lead.

This system is easy to install, and we’ve outlined the installation steps here.
First, you’ll need:
Then:
This system has a 5-year life span, after which you’ll need to replace it. If you need to change the filter earlier than that, CuZn provides a replacement as long as you meet the requirements in the warranty.
Here is a link to the official manual:

This product has no NSF certifications.
This filter has no earlier versions.
The CuZn UC-200 under sink filter uses activated carbon. How exactly will activated carbon attract contaminants to its surface for 5 years without needing replacement? We don’t see how.
Realistically, this filter can only remain effective for about one year unless your water contains little to no contaminants to begin with. If you really need to filter your water, we won’t advise using it for five years as advertised. We even found users who complained of poor water quality after using the filter for about a year.
To add to our doubts, this filter has no NSF certifications or testing (only the filter media is tested against NSF 42).
Another con is that you can only use the filter for city-treated water, not private well water.
Finally, some customers had leaks. We also read about carbon particles that someone found in the filtered water.
Pricing is okay for what the CuZn UC-200 Under Counter Water Filter does: Basic filtration of city water removing chlorine taste and odor, sediment, and maybe a bit of other organics and possibly heavy metals. But don’t expect crazy results, and definitely don’t expect 50,000 gallons filter capacity as advertised. Sure, you can use the system for 5 years, but it won’t do anything after around 1 year maybe, depending on water quality.
Let’s compare the CuZn UC-200 filter to the Clearly Filtered and Epic Smart Shield under sink filtration systems.
The Clearly Filtered 3-Stage (get the full review here) processes your water through three filter stages to remove most contaminants, including chlorine/chloramine, PFAS, heavy metals, VOCs, fluoride, and arsenic. You can trust its reduction claims because they’ve been tested against NSF standards 42, 53, and 401. The system is also made in the USA, is easy to install, and comes with a 30-day guarantee and a limited lifetime warranty. Its only downside is its relatively high price.
The other under sink filter system, the Epic Smart Shield (review), uses a single carbon block to remove chloramine, chlorine, asbestos, cyst, lead, mercury, MTBE, turbidity, VOCs, Bisphenol A, pharmaceuticals, and other water pollutants. It has NSF testing and certifications, and comes with a lifetime warranty and money-back guarantee. The Epic is also made in the USA and is pretty easy to install and maintain. The only downside is its lower flow rate (1.25 gpm).
Bottom line: The Clearly Filtered has the best features and broadest contaminant removal, so we’d recommend it if it meets your budget. If you have a lower budget, your ideal option is the Epic Smart Shield — it removes more contaminants than the CuZn UC-200.
