Product review (1 stars): My APEC RO system I bought for the sink pulls it all the way down to 30PPM and those 30 are probably the addition of some minerals it adds with the last step of the process to make the water taste better. Considering these Bosch filters only take out 35PPM
This product came as stated so this has nothing to do with the seller.  The problem is that I bought a water tester and took readings from the water with this filter and without it.  It only brought down the contaminant PPM from 490 to 455.  That's only 35PPM.  My APEC RO system I bought for the sink pulls it all the way down to 30PPM and those 30 are probably the addition of some minerals it adds with the last step of the process to make the water taste better.  Considering these Bosch filters only take out 35PPM, are pricey, and literally only last 2 to 3 month before the refrigerator throws up the orange "change" light and stops making ice, these (and all similar I'm betting) filters positively suck.  Better off just drilling through it and letting it pass strait tap water and save hundred bucks a year.  30PPM reduction is a joke.  A coffee filter can do that.
