Review on 2-Pack Membrane Solutions Reverse Osmosis Membrane 50 GPD 1.8"x12" Water Filter Replacement for Under Sink RO Drinking Water Purifier System by Jorge Tupou

Revainrating 5 out of 5

Excellent value for money for water filtration and softening systems

I'm running a pair of 50 GPD reverse osmosis membranes in parallel in a modified Watts Zero Waste system. I've used other inexpensive diaphragms but they didn't last very long before restricting flow enough to break my pump. I've been using Watts membranes for about a year and they still flowed well, but the TDS slowly increased to around 18. Just pop them in and they started out at around 300 TDS, which is fine. I ran 5 gallons through them and the TDS dropped to 6 on one and 8 on the other. So far, so good.

Pros
  • 💧 LONG LIFESPAN: Delivered dry in the original sealed packaging, the membrane element has an expected lifespan of 24 to 36 months, depending on the average quality of the feed water, the temperature and the pressure of the incoming water .
Cons
  • Ugly Packaging
