Membrane Solutions NSF/ANSI 58 Certified 75 GPD Reverse Osmosis Membrane

GOOD PRICE. DID THE JOB.

Excellent replacement with easy installation. Last exact one was purchased 4 years ago. Used for kitchen sink dispensing

Easy to install better water taste, durable nice appearance and reasonable price. Functionality and durability are good.

Works extremely well, it probably the same manufacturer that replaces the RO Buddie membrane because they both look exactly the same but this is cheaper! Works perfectly.. I test each batch of RO water and the results are incredibly perfect!

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.

Installed.in a 4 stage ro system, getting 7 TDS , with a source water about 220 TDs. Very happy. Didn't know what to expect with the low price, but this really works.

I use the Membrane Solutions 400 GPD RO membrane for concentrating maple sap, and it’s been a strong performer. It consistently boosts sugar concentration, cutting boil time and fuel use. Even when pushed toward its upper performance limits, it continues to run reliably without major drop-off when the system is set up properly. The membrane cleans up very well and has held performance over multiple seasons with proper flushing and storage—definitely adds to its value. Customer service is also excellent. They were responsive and helpful with setup questions, which is a big plus when adapting this for sap instead of standard water use. Bottom line: Great performance, easy to maintain, long-lasting, and well-supported. I’d buy it again.

Perfect fit for my RO BUDDIE. Easy to install. Output RO water PPM is around 4 to 5 ppm. Great way to rejuvenate my RO system. Great value.

j'ai changer la membrane de mon systeme osmose ECOWATER eco-435 et fit parfaitement!

Works well

Fits and works as expected.

الفلتر كفو وجودة ممتازة بس 50 جالون لا انصحك فيه خذ نفس المنتج بس 75 جالون افضل من هذا

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