GB/t32610-2016 is not necessarily able to prevent coronavirus. This standard is the technical specification for daily protective masks, and is the first national standard for civil protective masks in China, and masks that implement civil standards do not belong to medical masks. This standard corresponds to protection levels A, B, C and D, and filtration levels 1, 2 and 3. Only those with protection level A or filtration level 2 or above can approximate KN95 or N95 masks to prevent coronavirus. The masks of this standard are mainly applicable to play a protective role in daily life, such as the air pollution environment in daily life, anti-fog, etc. At present there are not many masks to choose from, if you really can’t buy the applied protective masks, you can also refer to this civil standard, but buy the higher level as much as possible.
