Customer Reviews

2 Stage QuickTwist Undersink Water Filtration System is rated 3.0 out of 5 by 3.
Rated 4 out of 5 by from Undersink Filter Set The filter was easy to install, but the adapter provided did not work with my faucet. I had to buy and install a double outlet isolation valve. I also provided my own faucet matching my kitchen set so the set had a lot of hardware I did not use. Even so, I think this unit is a good value for this type of filtration system.

Rated 1 out of 5 by from I was skeptical of this, since it uses quick connections, on the unit. I was right. They leak. If you have to remove the 1/4" tube, for any reason, you cannot re-connect it. It will leak. Dupont should've used REAL 1/4" male connectors, with threads. I now have to replace the entire top part, of the filter system. Home Depot does not have a replacement connector.
