75 GPD MEMBRANE (98% REJECTION RATE) Hands down the best membrane for our hobby.


Compatible with all RO systems


FILMTEC reverse osmosis membrane elements for home drinking water are the industry's most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. FILMTEC elements are shipped dry for convenient handling and long shelf-life. These elements are NSF/ANSI Standard 58 listed. Equipment suppliers can take advantage of FilmTec's Standard 58 listing and participation in the NSF Data Transfer Protocol to reduce costs for reduction claims for their systems.

  • Rated at 50 psi
  • Will purify about 20% more water than competitive elements rated at 60 psi


1. Permeate flow and salt rejection based on the following test conditions: 250 ppm softened tap water, 77°F (25°C), 50 psi (3.4 bar), and 15% recovery.
2. Permeate flow rates for individual elements may vary +/-20%.



  • Does the job, easy to install By Mr. Microscope on 1/26/2015

    After three years with my RODI unit doing the job, I decided it was time for a refresh on the RO membrane (in addition to my yearly update on the rest of the unit (filter, carbon blocks, DI resin)). I received my RO membrane and was like, "...uh, what now?" I quickly found this article from BRS explaining every aspect of replacing the unit with all sorts of tips for getting the job done.
    Just a few minutes later, I had it installed and was running water though it. Thanks for the write-up BRS! Great product.
  • Best membranes on the market By chromiumlux on 1/19/2015

    I have used these membranes from day one and will continue to use them.
  • CLEAN WATER By Mark on 1/14/2015

    wasn't sure this would fit since i had got my rodi unit at another site. Well if DID and the new membrane i feel works even better, was easy to change, and a great value and allowed me to order other items at once from same site.....bulk reef supply is really a one stop shop for reef keeping..
  • Excellent fit and finish By Sympley on 1/13/2015

    So far so good. I was going through DI cartridges at a rate of 1 per week. It was time to replace the membrane. This one seems very well build and good quality.
  • Price! By Tim on 1/8/2015

    My local store charges almost 3 times as much as BRS. BRS has great service, great price!
  • Great product better customer service By Thomas on 12/30/2014

    Called with a question about my ro unit and BRS got me exactly what Ineeded. Great price and easy to change out.
  • Works perfect By Ryan on 12/10/2014

    My TDS is 0, RO membrane from last year is still working strong and I know my water was filthy because the city recently did work on the piping and had an outbreak of algae. Their response was to bomb the city system with enough chlorine and chloramines to kill a horse. That being said, the fish never knew! Highly recommend these membranes, they last.
  • Good quality product By Tony on 12/7/2014

    This is a good quality product that is very easy to replace. I would not hesitate to recommend to others.
  • great membrane By matt on 11/12/2014

    This is the second one I've purchased from BRS. Brought my tds right back down to 3,so after it goes through the di chamber the tds is zero. Can't go wrong with using this membrane.
  • Quick and easy By Keith on 11/7/2014

    Very simple to swap.
  • Works Like A CHAMP By JCulmo on 8/8/2014

    First of all anyone concerned about the compatibility of this membrane with a Coral Life II 24GPD system, don’t be. This 75 GPD membrane fits perfectly with no problems to speak of. Make sure if you are upgrading the output (in my case 24 GPD to 75 GPD) membrane, be sure to get the matching flow restrictor and put the restrictor on the waste side of the membrane (in my case it is the red waste water side). It took be all of about 10 minutes to install and upgrade, of which 5 minutes was spent trying to get the old membrane out LOLOLOL. If you are considering this upgrade, just do it. The price is the best out there and of course, it comes with the best service and prices that we all love BRS for.
  • EASY and RELIABLE By rppvt on 6/3/2014

    BRS doesn't cut corners. this is the best company for RO membranes out there. And it's easy to install (comes with instructions!)
