Reverse osmosis water systems

Reverse osmosis (RO) pushes water through a semi-permeable membrane to strip out dissolved solids, lead, fluoride, nitrates, sodium and most contaminants — producing the cleanest drinking water available at home. Choose by where you need it and how much you use.

Which RO is right for you?

Under-sink RO — the standard for clean drinking and cooking water at one tap. See under-sink RO systems.
Whole-house RO — for very high TDS, salty or brackish supplies where every tap needs treatment.
Commercial RO — for restaurants, labs, car washes and light industry rated by gallons per day; see commercial reverse osmosis.

Sizing & maintenance

Match the membrane's GPD rating to your daily demand and feed-water TDS. Soften hard water before an RO to protect the membrane, and plan on periodic pre-filter and membrane changes. We stock replacement membranes and pre/post filters too.

FAQ

Does RO remove healthy minerals? It removes most minerals; many users add a remineralization stage for taste. Do I need a softener with RO? On hard water, yes — it dramatically extends membrane life.
