Works with both Pentair GRO and conventional RO systems
The Pentair GRO-75EN (4005460) is a 75 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.
