Mineral Maker comes with one mineral stone pouch. 

You can purchase another mineral stone pouch for replacement after using Mineral Maker 5~6 months.

Do not add coffee, tea or processed beverages to Mineral Maker. 

If you do so, the mineral stone pouch may become contaminated causing the water to smell bad. 

The main purpose of Mineral Maker is to make magnesium-enhanced alkaline mineral water. 

Although it does remove bad odor from water, it does not have a wide range of water filtering functions like common household water purifiers. 

The alkalinity of Mineral Maker is a pH of 8.0 to 10.0. Alkalinity may differ depending on the time of making the magnesium-enhanced alkaline mineral water.

It can be easily confirmed by testing with a BTB reagent. 

Take some water as a control before putting into Mineral Maker and the water placed in Mineral Maker after 30 minutes to 1 hour of being added, place them in different cups, then add 3~4 s of BTB reagent, and you will see that magnesium-enhanced alkaline mineral water has been made.
