Do you think it's safe to change a new mask every day?
Due to the current domestic epidemic trend is not fully stable, coupled with the approach of the new year, the national population flow is gradually rising, making how to correctly wear masks again become a hot topic.
It's winter. When it's alternating between indoor and outdoor, the larger temperature difference will make the inside of the mask produce water vapor. Many people think that water vapor will not affect its protective effect, but this is not the case.
In response to this problem, disease control experts said:The mask mainly relies on electrostatic force to absorb viruses and aerosols. Once the mask is wet, its electrostatic effect will disappear, and it can not play its due protective effect,Therefore, once the mask is wet, it is recommended to replace it as soon as possible.
In addition, hand hygiene should be well done before and after wearing the mask. At the same time, the positive and negative sides of the mask should be distinguished.
It's worth noting that,Each mask should not be used for more than 8 hours.
Not only that, in the use of hand sanitizer, should try to keep more than 20 seconds, otherwise it can not play a good disinfection effect.
Again, I need to remind you,When entering and leaving crowded places, remember to take personal protective measures.
