Love these membranes!
I switched to these membranes a while back. I use them at work with DI after the RO system. Most importantly they always reject at least at 99%. I use the 100 gpd. With a permeate pump it will perform better and make water faster by about 80% when used on a drinking water system. I consistently see the tds at 1 or 2 ppm out of the membrane. Not the case with a lot of other membranes.These hold at 99% for a long time like a year or longer. Really depends on the incoming tap water temperature. tds, pressure and a water softener really helps RO systems run really pure. Then for drinking I use a mineral cartridge to add back in higher ph, Calcium and magnesium. So it will go from 1 or 2ppm to around 40ppm after the mineral cartridge. My customers tell me I turn them into water snobs..That’s how much they like the water including myself.

Solid budget performance
This is the second geekpure membrane I've used and both produced water in the 3-5 ppm range TDS from my 600ish ppm well water. This last go around I bought another brand thinking they were all the same. Major headache, as the first was passing 250 ppm after the initial flush. The replacement was slightly better at 220 ppm. Did a full return and bought this one as I'd done in the past and I'm back to 3-5 ppm. The first membrane was in service for 2 years and had finally crept up to 20 ppm.

good filtration but a little slow
my tap water is around 300ppm. I'm getting it down to 9ppm with these filters. I'm running two 100gpd membranes which is making about 140 gallons per day at my regulated 40psi of household pressure. I kinda wish i bought the 150gpd membranes so i could be closer to a true 200gpd. I'm sure if i hooked it up to my unregulated hose bib on the side of my house which is 80psi i would get that but last time i bought 150gpd membranes i had much higher ppm for my filtered water, so I'll stick with these for now. Biggest thing for me is they work and get me very close to 0ppm

Works as it should
Great price for a quality product. Fit my generic RO system perfectly. This is a higher capacity filter than what I replaced and id definitely go that route the next time around.

Works but not at the listed rate
I have hard tap water and pretty high PSII checked my TDS coming it at 256-259 TDS. After the Geekpure membrane I am reading 13-15 tds. Average Rejection rate of about 94.92% okay rejection rate for this cheap membrane.

Works great
Water parameters are great

99% rejection at 8 gph
I was very skeptical, as I usually use Dow membranes, and they claim to be identical in performance at a fraction of the cost but these membranes have far exceeded expectations. My tds in is about 110 and tds out is reading 0 so it has nearly a 100% rejection rate and is producing 8 gal of water an hour, that’s 192 gal per day. I am running it at 100psi and the water is probably about 60F. With the Dow membrane having the same rejection rate but only produced about 120 gpd when new. It is noticeably faster which also means less water wasted.
