Drinking Water Reverse Osmosis & Aquarium Membranes

We use Axeon or Dow Filmtec membranes in every system we build for you. Our 50, 75 and 100 GPD Dow Filmtec membranes are rated at 50 PSI (US average is 65 PSI in our homes). Our Axeon 150 GPD membranes are rated at 65 PSI. Membranes last 3-5 years if you change your prefilters at least every year...If you missed a prefilter change you can expect about 1.5-2.5 years out of the membrane depending on usage. We replace aquarium membranes when they do not get at least a 90% rejection. Click here to find out how to perform a TDS test
