The impressive Amazon rating should tell you a lot about how well this filter works. Almost all customers who have reviewed it say, it has made a huge difference in their water quality.
The UC-200 uses three filters to clean up the water and give it a fresh natural taste.
Micro sediment membranes: These filter out particulates like rust, silt and sediment.
Coconut Shell Carbon filter: Filters out chlorine, heavy metals and various organic chemicals.
KDF-55: This is a bacterio static filter, meaning it prevents bacteria from reproducing. Unlike carbon-only water filters, there is no risk of mold or bacteria growing on the filter and entering into your water.
To ensure the highest performance, the UC-200 adheres to two important standards:
NSF standard 42: meaning it is certified to enhance aesthetic qualities of water (appearance, smell and taste) by removing substances like chlorine and sediment.
NSF standard 61: a standard that ensures materials and components used in water treatment products are high quality and safe.
If you live in one of the several cities that disinfect their water using chloramine, do not buy this under counter water filter.
The UC-200 is designed to remove chlorine only.
Luckily, the company also sells a model specifically for chloramine reduction. Look for the model name, CuZn UC-200-85.
Something else this filter does not remove is TDS or total dissolved solids. These are dissolved minerals and salts in water.
They are not a problem with most city water but can cause scaling and staining issues if you use well water.
If you want to filter well water, look for another under counter filter.
Do not use this water filter with untreated water. That’s because the water might contain waterborne microbes, which the filter does not remove.
You should only filter chlorinated city water. If you are concerned about harmful bacteria and germs in your water, I recommend a reverse osmosis filter instead.
High Filter Capacity
Most under sink filter cartridges last between 6 and 12 months, meaning you have to replace them once or twice a year.
The Cuzn UC-200 under counter water filter uses a high capacity cartridge that lasts for 5 years.
It has a capacity of 50,000 gallons, which breaks down into around 10K gallons a year for the average family.
Unfortunately, there is no filter life indicator. You have to note down the date you install the filter and remember to replace the cartridge after 5 years.
But even if you forget, you’ll know when you need a new cartridge. Your water will start tasting unusually bad.
Installation & Maintenance
You don’t need to call a plumber to install the UC-200 filter under the sink. It’s a simply DIY project that takes less than an hour.
The only complaint customers have is that it is bigger than they expected. Many struggled a bit to get it to fit under the sink.
But other than that, installation is a cinch.
The filter connects directly to the cold water line under your sink. There’s no need to drill a hole for a separate faucet on the sink.
But if you’d prefer a filtered water-only faucet, they can modify the installation kit just for you.
The filter comes with all the fittings you’ll need to hook up the unit to your water line. If you have non-standard plumbing, contact customer support and they will send you the right installation kit.
As several customers found out, they’ll even custom make certain components specifically for you to make sure your filter works. That’s great customer service.
The UC-200 is virtually maintenance-free. Once you install it, you can forget about it for 5 years when you’ll need to replace the cartridge.
Replacing the cartridge is easy. Unlike other filters where you have to open up the housing and remove the cartridge, you replace the entire unit minus the fittings.
The main unit is the cartridge. So you just remove the hoses that connect to it and connect them to a new cartridge.
In fact, Cuzn doesn’t sell a replacement filter for the UC-200 as far as we can tell. You simply order the entire 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.
It comes to around $20 per years of use.

More importantly, we love the filtering performance. This is one of the best under counter water filters for removing chlorine, chemicals, sediment and heavy metals.
If you are tired of buying expensive bottled water, get this filter. Your tap water will taste as good as bottled water if not better.
We also love the easy DIY 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. It saves you the hassle of going to the local store to look for them.
What We Don't Like About This Water Filter
Our only complaint is the size. It makes installation a bit tedious but not impossible. You might need someone to help you fit it properly under the sink.But the larger size is understandable. This is a 5-year filter meaning the cartridge must be big enough to last that long.
