Do dust masks protect against viruses?

Whether dust masks can prevent viruses cannot be generalized. More types of dust masks, common, such as 3M8210 mask, surgical mask, activated carbon medical mask, ordinary dust masks. The dust masks are usually made of different materials, such as paper masks, ordinary paper masks, industrial dust masks and so on.

Whether the dust mask can antivirus mainly lies in the performance of its filter media, different dust masks use different filter materials, generally using composite filter materials, common filter materials are activated carbon fiber, activated carbon particles, melt spray cloth, non-woven fabric, electrostatic fiber, etc.; filtering effect on the one hand and the diameter of the particles, but also by whether the particles contain oil influence.

Such as 3M8210 mask using 3M proprietary high-efficiency electrostatic filter cotton technology, in order to meet the filtration efficiency of the performance of the premise, to minimize the It meets NIOSH standards for particles as small as 0.3 microns. Isolation of particles with a diameter of 0.075 microns has been successful with a success rate of 95%, and the prevalent coronavirus pneumonia virus has a diameter of approximately 0.1 to 0.12 microns and is an oil-free particle. to 0.12 microns in diameter, and are non-oil containing particles.

Therefore, this type of mask can protect against this virus; surgical masks are worn by health care workers when working. It is mainly used in medical outpatient clinics, laboratories, operating rooms and other demanding medical environment, safety factor is relatively high, for bacteria, viruses, and other health care workers wear masks. It is more resistant and, to some extent, protects against viruses. Other types of masks do not provide protection against viruses. We would like to remind you that you should pay attention to its type when choosing a mask.
