Its added the alkaline back into our RO water. PH has risen back to near 7.0 from the 5.0 it was with just the pure RO system. I havent noticed an affect on the taste of the water. There were some bubbles for the first 3-5 tanks, but that has since subsided. I think it helps my stomach having this higher PH water with my coffee. Its nice to have the minerals though and Ill buy again once this 6-month filter has reached EOL (end of life).

So far, I like it. I dont notice a difference in taste from RO water before and after installing this filter, but I used a pH meter to test, and it went from ~6.8 to low ~9.1. Clearly a significant improvement to less-acidic water that now contains all the minerals our RO system was removing.Will be interesting to see how long it lasts with our consumption.

The ispring FA15 increased the pH of my RO system from 6.1 to 8.4. and supplies vital minerals. The water tastes great. Installation was very easy with the add on kit. TDS changed from 15ppm before the FA 15 install to 31ppm after. The tab water shows 452ppm TDS.

GOod quality filters that go with my multiple iSpring 5-stage RO systems. I have 3 systems total so this makes it much cheaper to buy all my filters at once. It saves about 30% from buying the 1-year pack.

Works well. Need to flush for the first few gallons when brand new.
