DuPont is a leader when it comes to water treatment and filtration. Their 75 GPD membrane has a 99% rejection ratio, and most other membranes cannot make that same claim. Along with meeting NSF/ANSI standards the 75 GPD DuPont (formerly Dow Chemical) membrane is hands down the best membrane for our hobby.

Up to 99% rejection Dow membrane* - NSF certified

Compatible with all 10" RO Membrane Housings. Be sure to change the flow restrictor if you change the flow of your membrane.

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.
