RO membrane cartridge.
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.

7 TDS
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.

Perfect fit and nice GPD output upgrade for my RO system.
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 great
Works great but gets clogged fairly quickly then starts taking longer and longer to filter water. Easy to install but hard to get out.

Reliable, durable, and great support for maple sap concentration
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.
