Reverse Osmosis RO Filter Replacement Set with 75GPD Membrane-Pack of 5

We love ours!

Works great! Had a couple issues at first. But after finding the correct fitting to work with our water inlet, it works like a dream and I want to get one for our bathroom too because I get super thirsty at night.

Olive Ornum
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.

Debbie Davanzo
Great deal

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

James Lopez
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.
