H2O Recommends Pentair Membranes as the best membrane value. Pentair provides high rejection (removal) rates at a lower price: Pentair 50 GPD RO Membrane
This Standard Size Reverse Osmosis Membrane fits in a standard membrane housing like the one on the RO unit shown here.
The same standard membrane housing can accommodate RO membranes with capacities ranging between 18-100 gallons per day (GPD).
FILMTEC™ reverse osmosis membrane elements for home drinking water are the industry's most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. FILMTEC elements are shipped dry for convenient handling and long shelf-life. These elements are NSF/ANSI Standard 58 listed. Equipment suppliers can take advantage of FilmTec's Standard 58 listing and participation in the NSF Data Transfer Protocol to reduce costs for reduction claims for their systems.
FILMTEC home drinking water elements are rated at 50 psi and will purify about 20% more water than competitive elements rated at 60 psi (please see the datasheet for more information).
If you would like to change your membrane to a capacity other than what was originally in your Reverse Osmosis System, you must change the drain flow control also. The membrane and drain flow restrictor are sized to go together. Click here to view the drain flow restrictors we have available.
