AMFOR TW30-1812-100 is a 12" x 2" Domestic Reverse Osmosis Membrane that will provide 10US Gallons per day, 15.8 Litres per hour (0.38cubic meters) per day at optimum output. It is an Ultra Low Pressure Domestic Reverse Osmosis Membrane that can be used in most types of RO filters.

The Amfor membrane has a 50Psi output, which is the same pressure as most homes. This means you can expect to achieve a much higher RO water output than most other membranes that need a pressure of 60-70Psi, making them less suitable to the average home.

Other Reverse Osmosis membranes are difficult to remove from their housing, with pliers or grips need to be struggled with to break the seal. The Amfor membrane has a hexagonal thread on the end, so you simply insert an Allen key, turn, and remove the membrane. On top of this, the American Membrane technology means a 20% increased water output at lower water pressures.

AMFOR® reverse osmosis membrane elements for home drinking water are the most reliable. Advanced membrane technology and automated fabrication allow these elements to keep consistent performance and suitable for long distance transportation. AMFOR home drinking water elements are rated at 50psi and will purify about 20% more water than competitive elements rated at 60psi.

Operating conditions:
- Elements contain preservative solution, therefore the permeate from the first hour of operation should be discarded, to flush the protective solution in the elements.

- Keep elements moist at all times after initial wetting

- CSM elements should be immersed in a protective solution during storage, shipping or system shutdowns to prevent biological growth and frost damage.

If the operating conditions are not followed appropriately , we can not honor the warranty of the element as you will be unnecessarily reducing the life of the filters.


  • The standard storage solution contains one weight percent sodium bisulfite or sodium metabisulfite (food grade). For short term storage of one week, one weight percent sodium metabisulfite solution is adequate for inhibiting biological growth.
