For those who want more than just filtered water, a reverse osmosis system provides clean purified drinking water. Having a purified drinking water system in your home can save you $100’s of dollars every year compared to buying bottled water. Plus you will help reduce the wasted plastic being dumped into the landfills.

Pentair GRO-50EN High Efficiency 50 GPD Encapsulated Membrane. Upgrade your reverse osmosis today! Most reverse osmosis membranes have a 3 to 1, 4 to 1 or a 5 to 1 ratio.
