Diatomite is a kind of plankton (diatom) inhabiting lakes and oceans in Cretaceous period. After diatom died, it deposited into fossils for many years and became a natural mineral.

Diatomite can absorb and release water by itself because of its humidity regulating function. The surface of diatomite has innumerable fine holes, and the super permeability keeps the surface dry for a long time and has deodorizing function. Because of its fast-drying inorganic properties, bacteria, fungi and mites can not survive and reproduce.
