Elvan mineral stones for the Aqualine, AQV and Coolmart water filters.
Elvan is a special volcanic rock that occurs only in a few places on our earth. The Elvan stones in Aqualine systems come from South Korea. These porous stones can contain 18 different ionized minerals and trace elements that are slowly released to the filtered water.
The amounts released in the process are similar to the minerals found in natural water. Some of these Elvan stones are impregnated with silver. This allows no bacterial action to take place in the stagnant water. This allows the water to keep for weeks.
The stones can release the following minerals and trace elements, among others:
- calcium
- cobalt
- copper
- chrome
- germanium
- iodine
- iron
- potassium
- magnesium
- manganese
- molybdenum
- sodium
- phosphorus
- selenium
- silicon
- sulfur
- zinc
