Description
The 100US KDF/GAC Under Sink water filter is our most convenient, practical, and popular water treatment system. This commercial grade. in-line water treatment unit is designed for municipally treated COLD WATER ONLY. Simply attach this unit to the cold water line underneath your sink and enjoy clean, clear, good tasting water directly from the faucet. 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. They reduce contaminants in water using oxidation/reduction (redox). KDF media provides extended life, decreased maintenance, control of micro-organisms, and improved performance. GAC - Granular Activated Carbon filtration media bed reduces impurities, heavy metals, bad tastes, odors, colors, etc.

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.

Rating 100US Undersink Water Filter
 
We are very happy with the filter. At first we were not sure about the new quick connection (and reversed inlet/outlet ports), until we re-read the small addendum slip. The quick connection system worked great. Also appreciate that now bubbles flow uphill, rather than downhill to clear it initially.
