Customer Reviews:
Wanted to be sure to get the correct filter. Looked through Amazon, and difficult to see if you are actually getting the right thing. The price was about what anyone else was selling it for. Multi-order discount would be nice - maybe on two or more. Came quickly with no delivery problems.
Collected by Trustpilot.comThis is the best water filter we've tried. We use RO for drinking, but this filter removes the chloramines and other chemicals, making our cooking and cleaning water of higher quality and safer to consume. Plus, it has no affect on our rate of water flow.
Collected by Trustpilot.comShipping was prompt and price was good.
