Long overdue and pleased!

For quite a number of years, we had an on faucet filter. It did a pretty good job and certainly was way better than straight water for the tap. It was confusing to guess however but we always got it worked out going to be wanted a free stuff filter system it just never got around to it and with Corian and we always had a concern that the hole be drilled correctly. But we got it good plumber and he had installed a number of them including one of his own home and we are very happy. The water tastes fantastic. Spaghetti has got a new life as do other pastas as we use filtered water to boil them in We are very happy and will not look back!

Overall impression of the Aquasana 3-stage filter

I had my 3-stage Aquasana water filter installed at the line that feeds my refrigerator and ice maker instead of under my sink. Installation was very easy and the water tastes great. It brings me peace of mind knowing that harmful contaminants are being removed from the town water supply and I'm no longer recycling all those plastic spring water jugs.

Happy with the Claryum 3-Stage

We are enjoying our Claryum 3-Stage filtration system. The installation was straightforward, and we had fresh, clean water in less than half an hour. I'm really impressed with the strong water flow from the dedicated faucet. We're delighted that we chose Aquasana and the Claryum 3-Stage filtration system.
