75 GPD RO Membrane, Reverse Osmosis Membrane Element 11.75" x 1.75" Water Filter Replacement for Undersink Home Drinking RO Water Filtration System

exactly as advertised, works great. I measured a low of 2ppm, I’m sure this can get down to zero.

Very good filter, fits like the original.

Fit perfectly, Great price, and usual fast Amazon shipping.

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.

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.

Product is as described and a great price

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.

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