AOP-KF® Anti-Influenza Mask utilizes our AOP-KF® Solid Alkali as core filtering material. AOP-KF® Solid Alkali emits a healthy low level of chlorine dioxide (ClO₂) and hydroxyl radicals (.OH) to rapidly eliminate pathogenic micro-organisms (bacteria, fungus and virus).

Chlorine dioxide disinfects through oxidation. Substances of organic nature in bacterial cells react with chlorine dioxide, causing several cellular processes to be interrupted. Chlorine dioxide reacts directly with amino acids and the RNA in the cell. It affects the cell membrane by changing membrane proteins and fats and by prevention of inhalation. When bacteria are eliminated, the cell wall is penetrated by chlorine dioxide. Viruses are eliminated in a different way; chlorine dioxide reacts with peptone, a water-soluble substance that originates from hydrolisis of proteins to amino acids. It kills viruses by prevention of protein formation.

SGS certified the AOP-KF® Mask, after used for 7 days, still meets the Bacteria Filtration Efficiency (BFE) and Microbial Cleanliness requirements of EN 14683 Type IIR standard. [Test results: BFE > 99% and Microbial Cleanliness < 4 cfu/g]
