Review on 🔧 Enhanced Compatibility: Membrane Solutions Replacement Cartridge for Optimal Performance by Robert Diaz

Fits my GE FX12; 1 membrane 2 carbon block system. Total dissolved solids (TDS) 65 ppm with this membrane using a TDS meter. Distilled water was tested at 0ppm, branded bottled water at 31ppm using the same TDS meter. I was expecting a lower TDS. UPDATE 6/27/2021 I was contacted by Membrane Solutions regarding my high TDS after flushing a reverse osmosis membrane. They suggested that I keep flushing the reverse osmosis membrane and the TDS would fall off. I continued to use/flush the membrane and as another 50 gallons of water flowed through the membrane the TDS on retest dropped to 28. I am happy with this number as bottled water showed 31 TDS and distilled water showed 0 TDS. Thank you Membrane Solutions for reaching out to you for help.
