1, cigarette combustion will produce a lot of smoke (particulate matter), and at the same time produce gaseous substances, which have obvious taste and are quite complicated in composition. The particles that make up the smoke are not only solids, but also liquids, which will constantly volatilize at room temperature and give off peculiar smell. Choosing an anti-particle mask with activated carbon, such as 3M 8247CN/3M9042, can really filter out most particles, and the particles filtered on the mask continue to volatilize. However, due to the limited amount of activated carbon on the mask, it can only play a limited role in reducing the smell of second-hand smoke for a person with sensitive sense of smell.
2. Reusable respiratory protective equipment is a kind of protective mask called replaceable. Filters and poison boxes can be replaced, and rubber masks and their components can also be cleaned repeatedly for long-term use. To prevent second-hand smoke, you can choose the matching of filter elements. You can choose an A-class anti-organic vapor filter box with anti-particle filter cotton. If the effect is not enough, you can choose a multi-gas filter box, such as 3M 6006 filter box (which can prevent organic vapor, formaldehyde, chlorine, sulfur dioxide, hydrogen chloride, ammonia and so on. ) and 7502 silicone mask, and choose 5N 165438.
3.3M 9042 is a protective mask certified by KN90 in China.
