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.

Works great
Would as should. We use this as a replacement filter for the BRS 5 stage RODI filter system.

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.

Lasts for 24 - 36 months!
I just want to remind everyone that this part of multi-part filters lasts 24 to 36 months! The other components, sediment filter, carbon filter, de-ionizing filter, all only last 6 months (1 year at best) so don't keep replacing this one as often. I keep replacing mine too early.

Seems to be working well, only been running it for 1 month. Haven’t bothered testing the water yet.

Works well. Not had an issues with the membrane. I periodically check the TDS with an inline meter and the readings are very low. Much cheaper than the big brand names.
