This is a high-performance filter that intercepts fine particles (PFE 99%) and maintains its antibacterial and antiviral properties for up to three days using the antibacterial and antiviral material “Earth Plus™” and the nano-fiber filter “NafiaS®” developed by Shinshu Ceramics Co.

Earth Plus™ has been installed in more than 1,300 hospitals as an air purifier filter and has a strong track record as an antibacterial and antiviral material.

Earth Plus™ is a composite functional material of ceramics (titanium dioxide, hydroxyapatite, and silver [metal]) developed by Shinshu Ceramics. It is composed of ingredients approved as food additives, is highly safe, and is a technology that adsorbs and decomposes proteins such as bacteria, viruses, allergens, and odors (derived from bacteria).It is comfortable to wear with less burden on the skin and ears.

Three-layer construction with NafiaS® filters sandwiched between Earth Plus™ processed non-woven fabrics provides filtering and antibacterial/antiviral performance.
