Replacement RO membranes-Dow Filmtec

Removes Fluoride!

Available from 50 to 200 gallons per day replacements for most residential and commercial reverse osmosis systems.Reverse osmosis is among the most effective technologies for removing perfluorochemicals (PFCs), trace pharmaceuticals and disease-causing bacteria and viruses from drinking water. –

The DOW FILMTEC elements help remove contaminants that can lead to health risks, and reduce impurities such as calcium, magnesium, and iron. With a stabilised salt rejection rate of 99 percent at 75 GPD and 98 percent at 100 gallons per day, in standard sizes (1812 configuration), DOW FILMTEC BW-60-1812-75 and TW30-1812-100HR home drinking water elements offer premium water – faster. The new 75 GPD membrane uses new Dow membrane chemistries which have been customised to maximize element performance. The 75 and 100 GPD elements offer a balance of flow and high rejection, producing more water with 20 percent higher flow rates at standard test conditions. –

DOW FILMTEC residential elements feature longer lifetimes that can potentially reduce operating costs for OEMs and brand owners, as well as National Safety Foundation (NSF) safety certification and the ability for NSF data transfer to help reduce certification costs.

DOW FILMTEC RO elements are manufactured in an ISO certified facility in the United States. They are NSF/ANSI 58 listed for material safety requirements, which means their safety and performance have been evaluated by NSF International, the leading global provider of public health and safety risk management solutions. NSF is an independent, not-for-profit organization that tests millions of consumer, commercial and industrial products around the world.


DOW FILMTEC reverse osmosis (RO) membranes for home drinking water treatment units are the most reliable and consistent elements in the industry. Advanced membrane technology and automated fabrication allow Dow to precisely produce each and every element to tight, pre-defined specifications. Dow’s advanced and consistent RO element quality helps customers deliver systems that reliably provide low impurity drinking water. DOW FILMTEC elements are shipped dry for convenient handling and long shelf-life. The membranes should  be used  with activated carbon or carbon block pre-treatment. Post carbon polishing of the purified water is also recommended.

Used In:

  • Under the sink water treatment
  • Point-of-use reverse osmosis water treatment systems
  • Production of home drinking water from various sources


  • High flux results in greater yield (more water)
  • Shipped dry for long shelf life
  • FilmTec performance and quality
