- 100 GPD Membrane - DOW Filmtec
DOW Filmtec 100 GPD membrane features a 98% rejection rate at 50 PSI which makes it the most commonly used 100 GPD membrane used 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 on them to help preserve the membrane until it is ready for use. It is recommended to discard all water that is produced by the new membrane for the first hour of operation.

Great product By Japple on 3/25/2018Japple would recommend this product to a friendI have very hard water starting at over 530. I purchased 2 of these for my duel membrane filter and getting 26 ppm out to my di resin which is awesome. my last off brand membrane was getting 86 at best so this will greatly improve my di resin life.
Awesome water saver! By Dustin on 2/22/2017Dustin would recommend this product to a friendI should have done this a LONG time ago! Saves water and time!
Works great! By aquanut on 10/26/2016aquanut would recommend this product to a friendI purchased this to use in conjunction with the BRS 800 mL Flow Restrictor ( I purchased previously). I have a Coralife Pure-Flo II 50GPD 4 stage RO System that has a 1/4" Aquatec 8800 Booster Pump Kit installed on it. I wanted to increase my throughput though and this did the job. I needed to remove the exiting flow restrictor that I discovered was located in the 90 degree output elbow of my system and replace it with an 1/8" MPT to 1/4" push to connect elbow. My throughput has dropped from 30 minutes to 18 minutes (2 1/2 gal. jug). I'm glad it worked and thanks to BRS for carrying what I needed for my upgrade.
Awesome Product By TJ on 6/4/2016TJ would recommend this product to a friendThis replaced a 150 GPD RO membrane that I previous had. I had bought the unit used from someone else and I was going thru DI resin so fast it wasnt even funny. Changed out my RO membrane with this one and its working great!
Working well oninitial installation By James on 4/9/2016James would recommend this product to a friendI have just concluded a build up of my own design system. A Staged 2X100 GPD RO Membrane system and with the addition of a booster pump these unit are performing exceptionally well.

Can this 100 GPD membrane be used in other RO system? Such as the water general ro6100DINT? Thanks!
Will this work in your 75gallon system
Will the dow 100g membrane fit my aqua fx 100gpd unit
Your 100 GPD filter is listed as TW30-1812-100HP. Dows sight has it listed as TW30-1812-100HR. What is the difference between the two?
There is no difference in the membrane. It appears as if the HR vs HP may be a typo on our side. Feel free to let us know if you have any further questions!
