Does the disinfection protection card work

Merchants said in the publicity that the "sterilization card" produces chlorine dioxide when it comes into contact with air, which can inhibit bacteria and mites and effectively reduce bacteria and fungi. You only need to wear a "sterilization card" to replace the mask for sterilization and bacteriostasis. But in fact, the "sterilization card" is very unreliable.

Brief introduction of disinfection card

Disinfection card, a portable disinfection card with sterilization and bacteriostasis. June 2020 5438+ 10, Guangming. It is reported that the germicidal test effect of disinfection card is limited, and the substances in disinfection card are in danger of being burned after contacting human body.

Experts clearly pointed out that chlorine dioxide is an oxidation disinfection component, which can sterilize, but it must reach a certain concentration. Wearing the network celebrity "sterilization card", a little low concentration of chlorine dioxide will drift with the wind, which will not reach the effective concentration of sterilization, and the effect of sterilization and bacteriostasis is very limited.
