1. Personal protective equipment designed to prevent or reduce dust in the air from entering the human respiratory organs to protect life;
2. Material: Anti-particulate mask is mainly made of two layers of non-woven fabric, with filter cloth (melt-blown cloth) in the middle.
3. Filtering principle: Filtering dust mainly depends on the middle filter cloth. Since the meltblown cloth has electrostatic characteristics, it can absorb the positive electrode particles. Since fine dust is adsorbed on the original filter, and the original filter is static and cannot be cleaned, the self-priming filter type anti-particulate respirator needs to be replaced regularly..
