We have filtered (RO) water in the kitchen; I bought this to add a second faucet to our basement sink (for cat bowls - spoiled kitties). I didn't want to spend a lot; it worked well and was good value for money. I don't think I would install it in my kitchen; I'm not sure if it's reliable enough for everyday use. They sell two models and didn't actually send me the one I ordered. The connection is a little different, but I got it.
