## Questions & Answers

**Q: How many mg/l of sodium and other minerals does this add?**
A: Hi,

The filter contains mineral stones, calcite, and Corosex and the amount of these minerals can vary depending on how long the water sits in the Alkaline cartridge. When the system is not in use, the longer the water sits inside the cartridge, the more concentrated the minerals become. For this reason it is hard to determine the exact amounts of the minerals provided in the water supply. Please contact our office at 678-261-7611 if you have any additional questions.
