Dow Filmtec 100GPD Reverse Osmosis Membrane

The DuPont (formerly Dow Chemical) Filmtec 100 GPD membrane boasts a remarkable 98% rejection rate at 50 PSI, making it the most widely used 100 GPD membrane in the aquarium industry. If you prioritize slightly faster water production and have adequate water pressure, this membrane emerges as an excellent choice.

 TIP: New membranes have a slight coating to preserve them until ready for use. Discard all water produced during the first hour of operation.
