The
Pentair Pentek GRO-50EN replacement reverse osmosis membrane is a premium, high-efficiency RO element engineered for residential and light commercial under-sink water filtration systems. Part of the advanced
GRO membrane series, this 50 gallons per day (GPD) membrane offers outstanding purification performance with improved water recovery and extended membrane life compared to standard reverse osmosis elements.
This encapsulated RO membrane features a **Thin Layer Composite (TLC)** design with a 100% dry membrane for maximum shelf life and consistent performance. With superior rejection stability even at high total dissolved solids (TDS), the GRO-50EN delivers reliable reduction of dissolved impurities so you get cleaner, fresher drinking water from your existing RO system.
Engineered for easy replacement and drop-in compatibility with systems like the Pentek GRO-2550, this membrane is ideal for kitchens, offices, and point-of-use water purification applications. Its encapsulated design simplifies installation and helps minimize leaks, while maintaining durable performance over time.
