The 100 GPD Dow Filmtec RO Membrane is an innovative water filtration technology that utilizes reverse osmosis to purify water. Reverse osmosis is when water is forced through a semi-permeable membrane, removing impurities, such as dissolved solids, heavy metals, bacteria, and viruses.

This membrane delivers high-quality water filtration, making it ideal for residential, commercial, and industrial applications.

DOW Filmtec 100 GPD membrane features a 98% rejection rate at 50 PSI, making it the most commonly used 100 GPD membrane in the aquarium industry. If you require slightly faster water production and have good water pressure, this is one of the better options.

TIP –Brand new membranes will have a slight coating to help preserve the membrane until it is ready for use. Discarding all water produced by the new membrane for the first hour of operation is recommended.
