Almost perfect!

We’re having issues with regard to the flow of water. It’s too slow. It takes a very long time to fill up any size of container. What are we going to do? It is only strong on the initial flow right after we turn on the faucet. After a fee seconds, the water flow becomes super slow.

Great deal

We love our Geek Pure system and these replacement filters are a great deal.

Great filters and system

We love our Geekpure system had it for three years but we needed a bigger tank so we bought 4 1\2 gallon rather than 2 1/2 gallon that came with the system we use the water for cooking, drinking, and give it to our pets for drinking also.

Margie Kemp

I have been running my RO for 2 years now always having trouble with the Name brand membrane failing after 5 months and TDS running around the 300ppm Range From new. I have high TDS from my well, 900ppm +.These geek pure filters have been installed for over a month now and running at 34ppm by far the lowest of other providers. So far I am very happy for the performance the quality and the price. I will update my review once my membrane starts to fail. (Installed Aug 28, 2021)
