About it

The Pentair GRO-36EN (4005458) is a 36 gallon per day encapsulated reverse osmosis (RO) membrane used in many residential and small commercial reverse osmosis systems. It is an exceptionally water-efficient membrane typically offering up to 100% water savings compared to conventional membrane technologies. It accomplishes this while still offering excellent purification performance. It is a “dry packed” membrane to maximize shelf life.

The GRO-36EN (4005458) can be used both with Pentair GRO Reverse Osmosis systems and with RO systems that use conventional membranes. When using a GRO membrane in a conventional system, be sure to use the product drop-down selector to choose the membrane that ships with the matched drain-line-flow-control. Please see the retro-fit instructions in the resources section of this page to learn how to fit the GRO membrane to your non-GRO RO system.
