I added this water filter to our home to stop relying on bottled water as the city water is super hard. The system was pretty easy to install and leaves the water tasting like fresh spring water.

Michael · 9 days ago

Arrived quickly. Install is not too bad as long as you are comfortable drilling into a drain pipe, and drilling a hole in the top of the sink. The push connection from the unit to the faucet is a bit tricky. Make sure you really push it on, or it will suddenly begin leaking sometime after install. Once up and running the unit is great, and the water tastes excellent.

David · 12 days ago

Installation was easy. I did use a different faucet, that better matched my kitchen faucet color scheme. The rate of flow lessens, after a few seconds but still provides water with only minor delay. I haven't had the filtered water tested, so can only assume that it is as pure as would be expected. On a side note, Your customer support staff are very kind and responsive.
