Filter Cartridge Reverse Osmosis 1.8x12 100GPD FI-TFM-100 GE Osmonics

This membrane is rated at 100 Gallons Per Day. It will fit in the majority of standard membrane housings and work in the majority of residential reverse osmosis systems. If you have chlorinated water, we recommend you use an activated carbon pre-filter as the residual chlorine in municipal or "city" water will destroy the Thin Film Composite ( TFC ) membrane. ClearChoice reverse osmosis membrane elements are for home drinking water. The semi-permeable membrane produces pure water for drinking, cooking, and other applications.
