Quick Overview

GE Osmonics 100 GPD membrane features a 96% rejection rate at 65 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.

BRS generally recommends the use of the 75 GPD DOW membranes because it offers 98% rejection at easier to obtain water pressures. The higher rejection will result in better quality water and lower DI resin consumption.

  • Great Membrane By John on 4/1/2014

    Lasted me over a year with moderate use so im happy with that. Definitely one of the best prices around.
  • 100GPD By Avfreq on 3/8/2014

    Worked great for about a year!
  • Best Price, Works Well By Shannon on 7/19/2012

    Bought this one last year when the 150 GPD Membrane was out of stock. It worked well.

    Don't forget to check if the right flow ristrictor is on your system.

    BRS had the best price I could find.
  • Will not buy again. By Mark on 4/18/2012

    Used this membrane for less than 6 months and TDS shot to 64!
  • Will not buy again. By Mark on 4/18/2012

    Used this membrane for less than 6 months and TDS has shot to 84! Must have gotten a bad membrane:(
  • Best price for top quality By Mark on 3/26/2011

    Thanks to my Dual Inline TDS Meter (DM-1 HM Digital) I could clearly see that it was time to replace my membrane. This is the best price I have seen for this top quality membrane. BRS does it again.
  • Perfect for my RO/DI system! By Erika on 2/10/2011

    I purchased this replacement membrane for my RO/DI unit and it was less expensive than where I was buying it previously but the exact same product. Thanks BRS!
  • On my system its great By Todd on 3/24/2010

    It must be that my water is very clean to begin with because the most TDS I have seen leave this is 1 and is usually 0 . I will probably go with a fimtec 75gpd when this one expires but for now I am completely happy. My water pressure is 100 psi coming out of the tap so I have to regulate it down to 80. This membrane when my water is at spec(77 deg.) puts out about 150-160 a day of water.If the water is the usual 55-60 degrees it puts out 100 a day.This is because of my water pressure.If it is lower you might not get the performance
