This is the last of 8 filters in my reverse osmosis system including de-ion and fluoride with 60 psi pressure regulator and flow restrictor and the water is mostly neutral at 7.2 PH. I will try another brand of filters as this is my second time buying this brand and I wasn't satisfied. I've just started adding less than a pinch of sodium carbonate per gallon of bottled water. This puts the PH at 7.6
