About this item
- The RO membrane removes not only harmful pollutants but also minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7.0 or below. Alkaline filter produces pH8-9 alkaline water with restored minerals such as natural calcium and magnesium.
- The Alkaline filter can be added to any under-sink water filter or RO system.
- Raises pH level to 8-9
- Updated FA15 alkaline filters are built with a secure push-fit quick connection, which allows faster filter replacement. If you have trouble installing the filters, please refer to the user manual or contact us

I bought this to raise the pH of my drinking water back up from reverse osmosis waters naturally acidic level. Each of these raised the pH of the water slightly, so I picked a target pH level (matching a brand of bottled spring water I liked) and ended up chaining four of them to get my water to match it. With that, the water now has less of a harsh taste. It tastes...softer and gentler, I guess. Its much easier to drink. A slight downside is that I do get a slight mineral buildup on the inside of my frequently-used containers, but its easy to clean off.Keep in mind that you will also need one of these kits (or equivalent) to be able to mount and plumb this module:http://www.amazon.com/iSpring-ACL1-Add-on-Filter-Kit/dp/B00M8B537Y/Additionally, if you are trying to tune the pH level of your water, I would recommend buying a pH meter so you can do it by the numbers rather than guessing. This one worked well for me:http://www.amazon.com/Dr-Meter%C2%AE-Automatic-Temperature-Compensation-Measurement/dp/B00PU0W35K/If you dont like the taste of reverse osmosis filtered water, I would definitely recommend trying one of these.
