<P>PROBLEM TO BE SOLVED: To provide a sanitary mask, where pathogenic organisms such as bacteria, and virus are effectively decomposed by using fine ferromagnetic ferrite particles. <P>SOLUTION: The mask body 1 of the sanitary mask A includes a removal layer 11 where fine ferromagnetic ferrite particles 11b are scattered and attached over the base cloth fiber surface to remove the pathogenic organisms; an inner layer 12 arranged on top of the removal layer 11 on its nostril side to pass respiratory air through; and an outer layer 13 arranged on the removal layer 11 opposite the inner layer 12 to pass respiratory air through. In the mask body 1, the respiratory air pass through resistance R1 of the inner layer 12 is made higher than the respiratory air pass through resistance R2 of the outer layer 13. <P>COPYRIGHT: (C)2011,JPO&INPIT |
