The main characters are the unique components of the Bio Green system.
1. The BIO Green air filter with catechin works on the principle of grasping dust particles thanks to static electricity. Catechin contained in the filter neutralizes the caught bacteria of staphylococcus, E. coli and many other pathogenic organisms. It is the catechin that adsorizes the unpleasant smells of sweat, cigarette smoke and household chemicals.
