Geekpure Universal Compatible 75 GPD Reverse Osmosis Membrane-NSF certificated -Pack of 2

I doubt I will be changing the filters as frequently as recommended, but I will say that these do a excellent job and be careful to keep the instructions that comes with them. The pictures were necessary for me to tell one type filter from another. Good products and good instructions. That's the way to do business.

Installed easily and works fine.One thing to remember is that these membranes are packed with a preservative when new and must be flushed for a good 30 minutes before you start collecting water to drink. It didn??t say that anywhere in the instructions.

Not sure about GPD but I'm getting around 94-95% rejection rate at 40PSI. My pressure is a little low, I believe with higher pressure I would get a higher rejection rate. Regardless, it's performing way better than the expended membrane that it replaced. It was getting an 85% rejection rate. Really good price on this.

Previously I couldn't get below 28ppm with the old unit, now I'm usually around 5-7ppm from 147. It has been in use for about a month now and I am using a permeate pump so ymmv.

Great water filter, especially for the price, it took a little extra time to get to me but they mentioned the delay and I was in no hurry and no worries.

it was compatible with my system ( I-Spring) few bucks cheaper and even looks exactly the same...guess its all made by same manufacturer...will re order again

Ordered two as I have a dual membrane piggyback setup for my aquariums and they work perfect. Install was easy as it should be and the price was right. Delivered quickly and packaged well. I order these here every six months and have never had any issues.

Not really alot you can say about a new membrane. It fits a standard housing snugly and my tds is 0. I used this for a upgrade to my existing rodi unit to increase production and reduce waste water. I have no complaints.
