Schungite Media

Schungite is a lustrous carbon mineral rock deposit and is extremely rare on our planet, with most of the known deposits being in the lake region of Karelia, Russia. Schungite has scientifically known unique healing, mineralization and antibacterial qualities, and has been used for hundreds of years to heal wounds and restore health. “Taking the waters” in the Karelian Lakes was a common occurrence for ill and injured people in this area. A unique property of Schungite is that it contains naturally occurring Fullerenes (pronounced fullereens). Fullerenes are Nano materials discovered in 1985, and known as a carbon allotrope, part of the structure of carbon, which includes diamond and other carbon structures, it has sixty or more carbon atoms arranged in a ball shape. It has unique antibacterial qualities and curative qualities and has recently been discovered in space.

We offer optional Schungite post-filter for our R.O. systems which contains activated carbon and genuine Karelian Schungite.

Invortex® Technology
