400 Litre per day Genuine Dow Filmtec reverse osmosis membrane water filter.

Globally regarded as the most advanced reverse osmosis membrane manufacturer, it is no wonder there are a million cheap rip off copies of membranes that try to look as similar as possible to these (minus the new holographic labels). Cheap membranes are cheap for a reason, they just don't perform like the genuine thing.

The expected serviceable lifespan of a Genuine Dow Filmtec Thin Film Composite (TFC) membrane is 3-5 years depending on a number of factors which include:

• Feed water quality
• Volume of water treated
• Preceeding filter cartridges and thier ability to remove membrane damaging chemicals such as Chlorine
• Presence of bacteria in Feed water. Can greatly shorten the lifespan to a couple of months. Bacteria just loves to eat the membrane so please contact our office on 1300 879 283 if you plan to treat non chlorinated water such as bore water or tank water with your reverse osmosis water filter. Pre filtering the water with a Doulton Ceramic 0.2 micron sterisyl filter will greatly reduce bacteria in feed water.
