150GPD Water Saver 4-Stage Reverse Osmosis Filtration System — DOW Membrane

Pure water, less waste. Our highest-capacity water-saving reverse osmosis system delivers premium purification while conserving water — featuring advanced DOW membrane technology.

This 150GPD 4-Stage RO system produces up to 150 gallons of pure water per day — twice the output of standard systems — while dramatically reducing water waste. Removes up to 99% of contaminants including chlorine, fluoride, lead, arsenic, and dissolved solids. Learn how reverse osmosis works on our blog →

Why This System?

Standard RO systems waste 3-4 gallons of water for every gallon they produce. This water-saving design dramatically reduces waste while delivering even higher production capacity. If you care about water quality AND water conservation, this is the system for you.

Clean Water Is Step One — Bring It to Life with a Crystal Charging Chamber

At Rius Water, we believe truly exceptional water is a two-step journey. Step one is purification — that's what this RO system does beautifully. Step two? Bringing water back to life.

Our Crystal Charging Chambers restructure, remineralize, and energetically amplify purified RO water — transforming it from "clean" to "alive." The Chamber connects directly to your RO system via standard 1/4" tubing. No electricity, no maintenance, no filters to replace. Explore Crystal Charging Chambers →
