1. The purpose of respirator ffp3 is to prevent or reduce the dust in the air from entering the human respiratory organs so as to protect the personal protective equipment of life safety;
2. Materials: Most of the anti-particulate masks are made of two layers of non-woven fabrics inside and outside, and a layer of filter cloth (melt-blown cloth) in the middle;
3. Filtration principle: Filtration of dust mainly depends on the filter cloth in the middle. Since the melt-blown cloth has the characteristics of being electrostatically charged, it can absorb extremely small particles. Since the fine dust is adsorbed on the filter element, and the filter element is charged with static electricity and cannot be washed with water, the self-priming filter anti-particulate respirator needs to replace the filter element regularly
