I'd buy again.

It takes some set up and getting the filter ready, but it's easily done within an hour at most.

This system produces the

This system produces the best-tasting water. I didn't believe it would eliminate the well water taste, but it doesn't disappoint. We have completely stopped purchasing bottled water. I do not miss hauling those large, heavy packages of bottled water. The cold & hot water feature works perfectly. I highly recommend this product. The only drawback is that the tank that holds the water can be a little difficult to remove when the tank is ready to be refilled.

This machine solved my problem

This machine solved my problem for safe clean drinking water. I current rent and did not want a permanent solution installed in the home Iam in. When I saw this machine and its features I decided to give it a try. I've gone from dragging water bottles in the home weekly filled with fresh spring water to the convenience of filling the tank from my sink. Most of all, itis unbelievable what this machine filters out. The residue that sits on the water in the debris tank is beyond disgusting and really makes you think about the quality, or lack there of, of drinking water in America. Water drop, thank you for this solution and making my life easier!
