💧 Dow Filmtec TW30 1812 36 Reverse Membrane: Unmatched Water Filtration Performance Review

Update: I've just bought a second one to replace the first one and I'm getting the same output results. Mila. The filter works great. We have very hard water in Arizona. Inlet water is 284 ppm and outlet water is 16 ppm. 94% removal. nice😁

I think I received a fake diaphragm and not a genuine Dow diaphragm. This unit lasted us less than 5 months before it broke down and was producing water with TDS/PPM levels of 176-198! When it was first installed the reading was around 10 but it slowly deteriorated to the point where it was essentially tap water coming out of our reverse osmosis system. I used to buy membranes from a specialist reverse osmosis supplier and they will give our family 2-3 years of reliable service before needing…
