We purchased the ULTRA-UC water filter for our kitchen. I installed the filter system myself and it was very easy to follow the instructions. We purchased a brushed nickel water filter faucet from Lowes to match our main faucet and everything worked seamlessly. It did take a little over a week for the white sediment to dissipate but we just cycled the water off and on per the instructions and now that is history! We previously used a Berkey water system but after performing the red dye test on the black elements, we discovered that the filters weren't functioning properly. We are super pleased with the water from this system and feel much happier knowing everything that is being safely removed- more than the Berkey for sure! Thank you so much for a great system! We'll be recommending this system to friends and family!
