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

According to the experts, the optimum TDS for brewing coffee / espresso is 150 ppm. RO water is in the 25 ppm, so I was looking for something to raise it. With the cartridge Im now at about 130. Be sure to install between the RO membrane and he storage tank, not the storage tank and the spigot.
