Your original tap water supply always contains some minerals. Especially on the pacific side of Japan, including Okinawa, the land is more alkaline and minerals crystallize readily onto the electrolysis plates and some break off into the water. Although they look like foreign substances, there is no harm in drinking these mineral clusters. In order to prevent the mineral clusters from falling into the water, we recommend changing the setting to "acidic water mode" (run reverse voltage) and increase the pressure and quantity of water once or twice a day for 3-4 minutes to clean out the appliance. Because of the caustic lime1 situation in Okinawa, we recommend people living in this area to use the pre-filter2 (sold separately).
Depending on the situation, it may be appropriate to use both of filters together. When mineral clusters stick to aluminum or anodized aluminum3, it turns brown and becomes difficult to take off. Please refrain from using aluminum or anodized aluminum pans and pots as much as possible.

Okinawa is said to exist on top of coral. As a result, the water in Okinawa has a high mineral content.

2Pre-filter
A filter used in situations where the original water supply contains a high percentage of well water or chemical substance. The transparent filter makes it easy to tell when the cartridge needs changing.
