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.

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.

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.

Easy to replace.
This replacement RO membrane fit perfectly, no leaks. All you have to do is shut off the water, remove the pressure, remove the tube and fittings. Then you remove the canister, unscrew it and remove the old RO membrane and insert the new and then reassemble. I would say the replacement is easy, less than 10 minutes. I think it said you should replace the RO membrane every year, but mine was 1-1/2 years old, I did not notice any quality issues. After replacement you should let you RO run for 30-40 minutes to flush out any contamination.

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.
