Generally speaking, if the mask is not obviously dirty and deformed, it can be replaced without having to change it every four hours. However, if the mask is dirty, deformed, damaged, or has an odor, it needs to be replaced in time. It is not recommended for you to sterilize many masks on the Internet, such as steamer steaming, disinfectant washing, microwave oven disinfection, etc. Because the damage to the material is unpredictable, it is likely to cause deformation, aging, and loosening of the mask, which will cause the filtration efficiency to decline, the filter layer to be damaged, or there is no way to meet the air tightness requirements.
