DOW FILMTEC™ reverse osmosis (RO) membranes for home drinking water treatment units are one of the most reliable and consistent elements available in the industry. Advanced membrane technology and automated fabrication allow Dow to produce each and every element to tight, pre-defined specifications. Dow’s advanced consistent RO element quality helps customers develop, and maintain, brand recognition along with a reputation for building systems that reliably provide low impurity drinking water. DOW FILMTEC elements are shipped dry for convenient handling and long shelf-life. DOW FILMTEC TW30-1812-100 is rated at 50 psi and will purify about 20 percent more water than competitive elements rated at 60 psi.

Dow’s next generation elements have been precisely designed and are a fully compatible replacement for existing DOW FILMTEC residential RO elements.
