Aquasana Under Sink Filter

No more plastic pitchers and/or lugging cases of bottled water into the house! This is the best thing I've done for my family in a long time! This filter is rated tops by any number of reviewers- I use Wirecutter . Walmart delivered it quickly and our plumber installed it easily. I've also read that others installed it themselves with no issues. My water tastes great- my coffee is fresher and I couldn't be happier knowing the reports of toxins leaching from all the plastic we use in our daily lives will not be in our drinking/cooking water! I highly recommend this Aquasana under sink system.

Better than a Britta.

Easy, delicious water! Had to replace one of the plastic gaskets with a metal one from the hardware store for 75 cents, but other than that , it's fantastic and better than a stand alone Brita.

Very nice looking faucet, and filter system

We're really using the new filtered water system a lot more than the sink one. I used to get my water from there till recently, now I don't want regular water anymore. It's not tasteful anymore. Can't believe I used to drink that. Now my coffee and tea are even better. It was easy to install, all the parts you needed came with the kit. I'm glad I spent the money on this water filter system. Because I was tired of buying bottles and jugs of water. Now I can Just open up the valve when I want great water.
