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. 6 filters included.
- 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

A bit complicated to install and set-up if you arent an advanced DIYer. It has some confusing behavior when you first start it up - expels a ton of waste water and takes a whole day to fill the tank for the first time. Contrary to the instructions, it took much longer to fill the tank the first time and the ratio of waste water / pure water must have been 20-to-1. However, after filling the tank the first few times the system seemed to settle in and its efficiency got in line with what is described in the documentation. I live in an area with really bad water quality. I have lived here for ten years and still could not swallow the tap water coming out of my faucet. This unit provides the most neutral tasting water I have ever put in my mouth. I havent tested the water yet but I can tell it is very pure.
