Update: I wrote a great review within the first week of having it. However, for several months, water was sprayed onto the filtration system from random locations. Every time I use it my entire meter gets wet inside and out. I wish I'd called Revane or arranged a return while I still could, but reluctantly put up with it, thinking maybe I screwed up like that. It started with the fact that there was a leak at the faucet tightening point, but because water leaks from the seams of the product. Made super cheap. Really disappointed! As for water filtration, it takes maybe 1/3 the time recommended for any filter. Therefore, we need to change the filter at least every month, but after 2-3 weeks you will begin to notice changes in the purity of the water. Doesn't even deserve 1 star. Very happy with this filter system! Our water looks disgusting, it's really cloudy when poured, it has chemicals in it. The photo shows what water looks like immediately after pouring from the tap. The one on the right is our regular tap water and the glass on the left uses a polyurethane filter. Water does not have an unpleasant taste, it does not contain chemical residues. While we get alkaline water for our drinking water, I wanted clean, filtered water for my animals, forage crops, and for my baby's bath. I feel much better in life :)
