75 Gallon Per Day Residential RO Membrane

منتج ممتاز صناعة امريكية 100%

I've had my RO system for about two years now. I bought it with the 100gpd membrane but moved to the 75 as it suits my needs just fine. I test the water regularly as I use it for my saltwater aquarium and it always comes out perfect. Manufacturer recommends membrane change every year. I think this membrane would last longer under normal use though.Installation is easy and as long if you tighten the housing properly it'll never leak.This is the fourth time I've changed the membrane and I've never had a problem. I recommend this product to anyone who's thinking about using Ro.

I am very disappointed with the performance of this membrane. After the installation of the new membrane, flushing it, the quality of water has become worse. My old 2 years RO membrane did its job much better.

- GDP rating is too optimistic; - got just 10 months out of it in a household of 4 before performance significantly degraded. The previous I used worked for 4 years.[EDIT]After further investigation: my notice about longevity of the membrane was not correct, the system performance degradation was not the membrane fault

When first installed it produced 2-3 ppm water from my 30ppm city source. Within only about 9 months now it produces 27-28ppm from the same source with 45ppm waste water. Seems it has failed and is no longer filtering properly. I replaced it with a lower filtration rate from the same brand , if it fails in a similar time period I will not be buying from this manufacturer ever again. My previous OEM membrane produced 2-3ppm water and lasted 2 years before I preemptively replaced it . Almost wish I didn't
