GE Osmonics TFM-50EB Encapsulated RO Membrane is a 13.25" x 2.5" replacement filter with a 50 gallons per day capacity of pure drinking water. The TFM-50EB membrane is encased in a polypropylene housing built with a permeate check-valve, control valve and flow control, that eliminates additional fittings and potential leaks. This RO membrane reduces many pollutants and contaminants such as lead, barium, cadmium, chromium, mercury, nitrate, nitrite, TDS, and more from your water. The Osmonics TFM-50EB will fit many Reverse Osmosis systems that use standard TFM encapsulated membranes between 18 and 100 gallons per minute.* (If your system requires TFM-18EB membrane (which produces 18 gallons per day), this membrane will have identical dimensions and would fit.)

We have newer , TFM-50EN membranes in stock, they come without built-in flow restrictors. Older models . TFM-50EB, had built-in restrictors. Consult your RO system manual to see if you need one or already have it. Contact us if you need a restrictor and can't find one.

GE Desal TFM-50 (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. Crossflow 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.
