DOW FILMTEC™ Tap Water Reverse Osmosis < 4" Elements

DOW FILMTEC™ Tap Water Reverse Osmosis Elements feature advanced membrane technology and offer outstanding reliability and consistency. Our automated fabrication process allows precise production of every element to tight, pre-defined specifications, helping customers develop and maintain brand recognition along with a reputation for building systems that reliably provide low-impurity drinking water.

DOW FILMTEC™ TW30-1812-100HR

DOW FILMTEC™ TW30-1812-100HR Elements for home drinking water treatment units produce 100 GPD (15.8 L/h) of permeate with 98% stabilized salt rejection at standard test conditions. They are the most reliable and consistent elements in the industry. They are shipped dry for convenient handling and long shelf-life. DOW FILMTEC TW30-1812-100HR 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.
