Best for me
This is my goto membrane for my RO system. I've had good luck with them and am pleased with the price and performance.

Perfect fit and nice GPD output upgrade for my RO system.
I waited way too long to replace my previous membrane. Almost 20 years! This replacement fit perfectly and I'm very happy to have the higher GPD output. Quality seems to be excellent. I won't wait 20 years next time to make a replacement. I could tell the RO water quality was back to what it should be after making the replacement.

Lower measurement
Great filter, arrived quickly and price is good. Easy to install and package well. Water tastes great. TDS measures 29ppm after install before it was 80ppm. Water at non filter, measured 600ppm. The 29ppm will drop after some use.

Great Filter, Works Good, Fits Nicely, Easy to Install.
These are nice replacement filters for our Krystal Pure K10 reverse osmosis system. This one is a little tricky to replace as you have to remove a water line, but other than that it fit well and works good.

Long lasting membrane, well made, and is holding up well!
This membrane is still going strong after a few years. I try and change them out every 3 years. Seems well made, easy to install if you know how to work on RO systems and my TDS is still very low after a few years. Pretty happy with this membrane.

Good quality RO membrane
Supplying with fairly clean water (filtered to 1 micron, 230 ppm after softening, charcoal filtered) I got zero (<5) ppm; the membrane it replaced was at 30 ppm on the same supply. Rated 75 gpd; I got 38 gpd on 45 psi, supply water temperature 55F. This is a reasonable ratio of actual to rating; the membranes are rated at 65 psi and 77F. 100% would buy again.
