So N95 can't buy KF94 and it's no problem. But now the unit price of disposable masks on the market is 6 yuan, During this time buy a high level of protection. This is safe and affordable. What we need to affirm is. There are three Korean mask standards. KF80, KF94, KF99 Among these particles, the filtration index of KF80 is above 80%, with an erage of 0.6 microns, The facial air leakage rate is 25%, and the facial inhalation resistance is 60 Pa. KF94 particle filtration index is greater than 94%, with an erage of 0.4 micron particles, The facial air leakage rate is 11%, and the facial inhalation resistance is 70 Pa. KF99 filter element index is an erage of more than 99% of 0.4 micron filter element, The facial air leakage rate is 5%, and the facial inhalation resistance is 100 Pa. Therefore, many shopping malls or pharmacies he also given suggestions. KF80 standard mask Used daily to protect the respiratory system from sandstorms, Hazardous material particles, such as fine dust, Does not meet the requirements for pneumonia protection, If the price is high, it is recommended to buy. In terms of the use time of KF94 masks. I also want to tell everyone. It is different from general disposable surgical masks. Areas without outbreaks There will be no problems for two weeks. Anti-epidemic masks that are not in Korea must not be touched and washed. It is recommended to use ultriolet light for disinfection. Or wipe it with alcohol.
