There is no button to activate ions generation on the remote controller of my Ereada® mat, how to use this function?

Negative ions and Far Infrared come from the stones and inner anion generating layers naturally upon heat distortion created by the heating layer.

You can make it higher or lower by adjusting the temperature. Amethyst, jade, and other crystals usually emit about 200-300 ions.

Tourmaline microspheres enriched with special clays and volcanic elements generate up to 1000-1500+ Negative Ions per cm².
