Review on 2-Pack Membrane Solutions Reverse Osmosis Membrane 50 GPD 1.8"x12" Water Filter Replacement for Under Sink RO Drinking Water Purifier System by Charles Lewellen

This item is perfect for my GE RO water filter system.I believe these reverse osmosis membranes are standardized and will fit most devices.I have tested the water with a TDS meter after installing this membrane and the tank 2 times and the results are between 0.01 and 0.0. That's good. The water tastes just as good as the original. I also swapped out 2 activated carbon filters. The pH hasn't changed between tap water and filtered water, when I tested it with a test strip.
