What must be used to disinfect a respirator?

Using a 10% bleach solution is essential for disinfecting a respirator because it effectively kills a wide range of pathogens, including bacteria and viruses, which may be present on the surface of the respirator after use. This concentration of bleach is known to be effective in achieving a high level of disinfection while also being safe for metal and rubber components typically found in respirators when used correctly.

Other methods, such as alcohol wipes or regular soap, may not provide sufficient disinfection levels necessary to eliminate harmful microorganisms that could compromise the safety of the respirator. Additionally, while hydrogen peroxide has disinfection properties, it is not as widely recommended or standardized for this specific application as a bleach solution. Thus, the 10% bleach solution stands as the most appropriate choice for ensuring the respirator is properly disinfected and safe for subsequent use.
