Pentair Freshpoint Gro75-Rc High-Efficiency Reverse Osmosis Membrane - 75 GPD | Pentair

The Pentair FreshPoint GRO75-RC is a high-efficiency reverse osmosis membrane built around industry-leading Thin Layer Composite (TLC) technology, delivering a 75 GPD (gallons per day) flow rate with exceptional water efficiency. While most standard RO membranes operate at a 3:1 waste-to-product ratio (25% recovery), the GRO75-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. No other membrane in the industry matches this efficiency claim.

The GRO75-RC is NSF certified to reduce PFOA/PFOS ("forever chemicals"), giving it meaningful protection against persistent contaminants in addition to standard RO filtration performance. As a direct replacement membrane for the FreshPoint GRO-475 and GRO-575 RO systems, it's a straightforward swap for maintaining system performance over time.

Key Features:
- Thin Layer Composite (TLC) membrane technology
- 75 GPD (gallons per day) flow rate
- 1:1 purified-to-wastewater ratio - 50% recovery, double the efficiency of standard RO membranes
- NSF certified to reduce PFOA/PFOS ("forever chemicals")
- Direct replacement membrane for FreshPoint GRO-475 and GRO-575 systems
- Significantly reduces water waste compared to conventional RO membranes
