iO-MAX Mask

This mask is not designed solely for defence. It is designed to actively attack harmful particles around you.

Product Features


Ideal three layer structure that combines attack and defense!
・The outer filter (shield function) adopts the processing technology ViralOff® developed by the Swedish company, Polygiene. This reduces the amount of certain viruses on the fibers. (Testing method: ISO 18184:2019)
・The middle filter (attack function) uses a special fabric developed by AquaBank that generates 'negative ions'. It releases negative ions that attack odors and harmful substances that invade the facial area. (Patent pending)
・For the inner filter (skin-friendly deodorant function) deodorant stretch fiber 'ROICA® CF*2 is used. The smooth, bare mesh fabric is gentle on the skin and creates an ionized state on the surface of the yarn, which absorbs unpleasant odors (ammonia, acetic acid, isovaleric acid) and suppresses them.
