This unit is also compatible with water coolers, fountains, and ice makers. It features state-of-the-art engineering and design that has surpassed the most rigorous and demanding quality assurance testing. Patented KDF Process Media are high-purity copper-zinc formulations.

Rating Great filter for the kitchen
Our tap water has been contaminated by algues fow a few years now and the town isn't able to solve the issue. This water filter makes a difference in how the water tastes without significantly reducing the water pressure.

It took 3 days to finally get my filter installed. Called family for help since the install was completely different from the one I did before by myself. Couldn't understand "IF IT AIN'T BROKE, DON'T FIX IT!!!! After all is said and done, I am happy I have a new filter for my water.

I have used these filters since they were marketed by NSA. They are easy to install and last at least 3 years. Really make a difference in the taste of the water.

Rating Great product without compression valve
This is another of many NSA water filters we have owned over the years and are never disappointed except for the demand that we install the compression valve this time. We had to take it off as the water pressure was impossible to deal with.

Great product, as always. We've been using this kind of filter for many years. The instructions didn't match the unit this time. Hopefully the engineers flipped the guts to make the water flow do what it should inside. When I contacted the company, they seemed to be unaware of the issue.
