Anti-fungal, self-cleaning and biostatic properties result from a special high „very high dencity” coating plasma deposited in high vacuum. The coating on the inner side of a window consists from nano-crystals of doped titanium oxide. Titanium oxide can be activated by UV-irradiation but our composition is active also when irradiated by visible light. Titanium is a safe element for humans (implants are manufactured using titanium or its alloys, our immune system does not recognize titanium).
Air circulation causes pathogens to contact with a window surface (with antiseptic coating on the glass) and effectively their removal. Every day the same air is pumped several times along the widnow A unique feature of the DAG1 glass has self-cleaning property even without UV irradiation.
