Filmtec Membrane - 50 GPD

DOW FILMTEC™ TW30-1812-50 Elements for home drinking water treatment units produce 50 GPD (7.9 L/h) of permeate with 98% stabilized salt rejection at standard test conditions. They are shipped dry for convenient handling and long shelf-life. Dow’s next generation elements are a fully compatible replacement for existing DOW FILMTEC residential RO elements. DOW FILMTEC TW30-1812-50 elements have been tested and certified by NSF International against NSF/ANSI Standard 58 for material requirements only for safe use in drinking water applications.
