Pentair reverse osmosis membranes are developed for residential water filtration and feature advanced Thin Layer Composite (TLC) membrane technology. Designed to deliver consistent filtration performance, these elements are available in multiple capacities to suit different household RO systems.

The TLC membrane series offers permeate flow rates of 24, 36, 50, 75, and 100 gallons per day (GPD), making it suitable for a wide range of residential reverse osmosis applications.
The GRO (Green Reverse Osmosis) membrane series is available in 36, 50, and 75 GPD options. These membranes are designed to produce high-quality drinking water while reducing water waste by up to four times compared with traditional RO membranes, as stated by the manufacturer.
