Upgrade your reverse osmosis system's efficiency with the Pentair FreshPoint GRO75-RC replacement membrane (Item #655122-96). Built with an industry-leading Thin Layer Composite (TLC) design, this 75 gallon-per-day (GPD) membrane delivers a 1:1 recovery ratio — producing 1 gallon of purified RO water for every 1 gallon sent to drain, compared to the 3:1 ratio (25% recovery) typical of standard RO membranes.

This dramatic improvement in water efficiency means less wasted water and more usable purified water from every gallon that enters your system, without sacrificing filtration performance. The GRO75-RC is a direct-fit replacement membrane for the Pentair FreshPoint GRO-475 and GRO-575 reverse osmosis systems, making it simple to maintain peak performance in your existing setup.

For best results, replace the GRO75-RC every 1–2 years if your water supply is chlorinated, or every 2–4 years for non-chlorinated water, to maintain optimal contaminant rejection and consistent RO water production.
