Huining 100GPD RO Membrane 1812/2012 Residential Reverse Osmosis Membrane Water Filter Cartrige Replacement for Home Drinking Water Filtration System Household Under Sink Water Purifier

this is the best one I have bought this year I bought two others and they didn't work this one fills the tank in no time and you get a good flow from the tap. you need one buy this one I have tried the 75 and the 50 and they haven't lasted very long and the flow was really slow. and this is the truth from a real buyer

Been using the 150gpd filters for 6 months now with no issues good product

The membrane barely lasted 6-7 months before the TDS count climbed to 45-50 ppm and the RO system is constantly running trying to flush the membrane. A far cry from the sellers claim of 15-24 months. No way to contact the seller after the short-lived ‘product support window’ closed either. Save yourself hassles as well as your money and buy a membrane from another seller.

This membrane is so slow on water production, slow like it's clogged. And water tasted strange。 My tank never got filled since I have this membrane installed. I've replaced it with OTHER brand membrane, now everything works fine, and water tastes way better than before.

Pretty basic stuff ... it works :) My original filter had been in for over 6 years, so I hope this new one lasts just as long! Been in for a couple of weeks now without problems. I will continue to test the water with my little TDS meter.
