GE Osmonics Pentair TFM-50A RO Membrane is a 12" x 2" standard replacement cartridge with a 50 gallons per day capacity of pure drinking water. Culligan Compatible TFM-50-A RO replacement water filter membrane, made by Pentair reduces many pollutants and contaminants such as fluoride, lead, barium, cadmium, chromium, mercury, nitrate, nitrite, TDS, and more from your water. GE TFM-50A Reverse Osmosis membranes were originally designed for Culligan RO systems, and they will also fit many RO systems that use standard TFM membranes with double o-rings at the top tip, and that process between 24 and 150 gallons per day.

Original GE membrane TFM-50A has been discontinued. Pentair may be available, pls inquire. 

GE Desal TFM-50A (Thin Film Composite) is manufactured with "Membrane-Separation Technology" which employs crossflow filtration where captured impurities on the membrane are constantly swept away by the concentrate stream. Cross-flow filtration across the membrane then divides the flow into two outflow streams: the cleansed permeate feed and the concentrate or reject stream. This flow provides continuous cleaning that prolongs membrane life and reducing maintenance costs.

Membrane elements by GE are the brand of choice for most demanding applications. GE drinking water filters reduce many pollutants and contaminants with a premium membrane process that removes particles 100,000 smaller than human hair. The elements deliver outstanding performance and long-lasting operation.

  • Thin Film Composite Membrane for efficient purification.
