Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System

I recently purchased the Membrane Solutions Reverse Osmosis Membrane 50 GPD for my under-sink RO drinking water purifier system, specifically for my Olympia water filtration system. It fits perfectly and works flawlessly with my setup. The water quality has noticeably improved since I started using this membrane. Installation was straightforward, and I'm impressed with how well it filters water, ensuring clean and fresh drinking water every time. Highly recommend it

I like that it works just like the brand, and price was cheaper

I used this to replace the RO membrane in my Isprings reverse osmosis under the sink filter. Works perfect and is about half the price of the isprings brand.

Easy to install on APEC ROES-50. Works as expected.

Bought this RO Membrane filter for my iSping 5 stage RO water system to replace existing RO filter. This should last about 2 years. I installed it on Jan 6, 2024 and by end of February it was already non functional. It was so bad that it would take all night long, with booster pump running (and undue wear and tear on booster pump) and only produces about 2 quarts of RO water in the reservoir tank. On top of that it was a TDS of 134, far from what it should be compared to what the tap water was.I bought to save a few dollars. I ended up in first part of March 2024 buying the RO filter made by iSpring (aka 123filter) put that filter in, and immediately the system started functioning properly. Filled up the 3 gallon tank in about 2 hours. Pump then shut off. RO water is now around 32 ppm TDS and tastes great again.Bottom line: bought to save a few dollars, but instead had to buy another RO filter too soon, so since it was past the return window of 30 days, is now just a bad investment.UPDATE: Company reached out to me to resolve the sanctification issue. So I came back here to change the stars and would say that it might have just been a faulty (defective) item from the beginning.

I try to change it every other year to maintain water quality and this is a good product compared to other Chinese knockoffs. Water gets to 25 PPM which is acceptable.

Good item and priced right.

I purchased this to replace the membrane on my Krystal Pure KR10 RO system.It was quick and easy to swap out and fits perfectly.Thanks!

Improved the water quality

Seems to be working well, only been running it for 1 month. Haven’t bothered testing the water yet.

Works as intended.

👍👍👍👍
