Membrane Solutions NSF/ANSI 58 Certified 150 GPD Reverse Osmosis Membrane | 12"x2" RO Membrane Replacement For Water Purifier, Aquarium Reef and Maple Syrup DIY RO System, 1 Pack

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

I waited way too long to replace my previous membrane. Almost 20 years! This replacement fit perfectly and I'm very happy to have the higher GPD output. Quality seems to be excellent. I won't wait 20 years next time to make a replacement. I could tell the RO water quality was back to what it should be after making the replacement.

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!

This is definitely an amazing filter. Don’t waste your time looking elsewhere. This filter is definitely done it for us and I have already ordered another one so I have one on hand at all times.

Works great but gets clogged fairly quickly then starts taking longer and longer to filter water. Easy to install but hard to get out.

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.

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.

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