Dow FilmTec BW60-1812-75: 75 GPD TFC Membrane for Undersink RO Systems

Enhance your home water system with the Dow FilmTec BW60-1812-75 reverse osmosis membrane. This 75 GPD element is designed for undersink installations, delivering reliable performance with industry-leading membrane technology and automated fabrication that residential users can depend on. The membrane is compatible with standard 1.8" x 12" housings and is NSF/ANSI Standard 58 listed for drinking water applications. While environmental conditions vary, this element is engineered to provide consistent water treatment across a range of residential setups.

Key benefits and capabilities

• 75 GPD (7.9 L/hr) capacity for daily water production.
• 98% stabilized salt rejection (minimum around 96%), helping reduce impurities in filtered water.
• NSF/ANSI Standard 58 listed for safety and performance in home filtration.
• Compact dimensions: 11.75 inches long, 1.75 inches diameter, fitting standard 2" ID housings.

Important usage notes: the membrane is rated at 50 psi. In many setups, it can deliver roughly 20% more water than comparable elements rated at 60 psi under favorable conditions, though actual output depends on feed water quality and system configuration. If your water is chlorinated, a carbon/sediment pre-filter is recommended to protect the membrane’s Thin Film Composite (TFC) layer and extend life. Environmental factors such as water temperature and pressure can influence actual performance.

Compatibility and replacement guidance

The TW30-1812-75 and BW60-1812-75 are functionally interchangeable in most undersink RO applications. This element fits standard 1.8" x 12" residential membranes housings and can serve as a direct replacement. Our part designation MB-1812-75F identifies this specific membrane variant.

What to expect in real-world use

Users often notice clearer water and consistent production when used with a well-designed undersink system. Dow FilmTec’s automated manufacturing supports dependable performance across many home setups, while real-world results will vary with feed water quality and household usage.

Setup and maintenance tips

• Use a carbon/sediment pre-filter if your supply contains residual chlorine.
• Ensure correct housing fit and verify the 2" ID housing is compatible with the membrane.
• Monitor system pressure and temperature to align with the 50 psi rating and environmental conditions.

Note: The original manufacturer part number may appear as TW30-1812-75 or BW60-1812-75 in listings. Both refer to the same membrane element; MB-1812-75F is our current part identifier.
