There are three parts, including dust removal, deodorization and sterilization, in our high-efficiency photocatalyst air filter purifier. We modify the traditional methods of coating titanium-oxide on nets. By using powder metallurgy techniques, pure titanium beads under high temperature and oxygen-enriched air form panels with lots of vacancy. Because of the increasing contact area, this structure is more efficient in sterilization. In addition, It is more durable by oxiding itself than coating on nets.
