Geekpure 150 GPD Reverse Osmosis Membrane for RO Water Filtration System - NSF Certificated

These say 150gpm but it will never see that rate at my house. Seems to be working well though, water tastes fine and water waste from ro seems to be the same rate maybe 4 to 1.

These things brought my TDS to the lowest I've ever had. Easly to replace too

We've been using these membranes to concentrate the maple sap in syrup production for a few years. They work as they should and separate water from the concentrated sap.

This two pack of RO membranes are easy to install and do a good job at filtering my water. No issues with fit or function, these membranes work as expected and it fixed my failing RO system. I tested my water after replacing with a TDS meter and my system was now producing water in the 30ppm range which is good when compared to just tap water I get a TDS value around 200ppm which represents hard water. Overall this two pack of RO membranes was a good value that allowed me to replace and restore proper function to my RO system.

The filter was a perfect fit. The water tastes good and there are no leaks! I will buy from you again.

Items as described

I bought the two pack of 150 GPD membranes and am getting 100 GPD at most with both hooked up at the same time (50 GPD each) at 100-120 psi. The TDS out of the membrane also stayed high for hours staying at about 40 TDS out finally dropping to about 20-25. Other brand membranes have gotten me to sub 10 TDS. My input water is usually 2225-300.

Works perfectly
