Pentair Freshpoint Gro50-Rc High-Efficiency Reverse Osmosis Membrane - 50 GPD | Pentair

The Pentair FreshPoint GRO50-RC is a high-efficiency reverse osmosis replacement membrane engineered for the Pentair FreshPoint GRO-350B undersink RO system. Built with an industry-leading Thin Layer Composite (TLC) membrane, it delivers a 50 GPD (gallons per day) production rate while reducing dissolved solids and a wide range of contaminants for cleaner, great-tasting drinking water.

While most standard RO membranes operate at a 3:1 waste-to-product ratio (25% recovery), the GRO50-RC achieves a 1:1 ratio - 50% recovery - meaning for every gallon of water sent to the drain, you get a full gallon of purified RO water. This significantly reduces water waste compared to conventional membranes without sacrificing filtration performance.

As a drop-in compatible replacement for the FreshPoint 161110 (GRO-350B) system, the GRO50-RC features a color-coded, click-in design for quick, tool-free installation - keeping maintenance simple for both DIY customers and technicians.
