Before the population's immune barrier is established, even if some people are vaccinated, everyone's awareness of prevention and control and prevention and control measures cannot be relaxed. Therefore, you should continue to wear a mask after vaccination.

Ventilation resistance and airflow resistance test index requirements corresponding to each mask standard:

GB 2626-2006 Respiratory protective equipment: the total inhalation resistance of the mask is not more than 350pa, and the total exhalation resistance is not more than 250pa;

LFY-711 respiratory resistance tester

GB 19083 Medical protective mask: In the case of a gas flow rate of 85L/min, the inhalation resistance shall not exceed 343.2pa (35mmH₂O);

LFY-706C particulate matter filtration efficiency and airflow resistance tester

GB/T 32610 daily protective mask: the inhalation resistance of the mask is less than or equal to 175pa; the exhalation resistance is less than or equal to 145pa;

LFY-711 respiratory resistance tester

YY 0469 Medical surgical mask: The pressure difference is not more than 49pa;
