1. Personal protective equipment whose purpose is to prevent or reduce dust in the air from entering human respiratory organs to protect life safety.
2. Material: Dust masks are mostly made of two layers of non-woven fabric inside and outside, and a filter cloth (melt-blown cloth) in the middle.
3. Filtration principle: The filter dust mainly depends on the filter cloth in the middle. Because the melt-blown cloth has its own electrostatic characteristics, it can absorb positive small particles. Because the dust is adsorbed on the filter cloth, and the filter cloth is electrostatically charged and cannot be washed, the dust masks are all disposable.
4. Remarks: The international requirements for the use of dust masks are quite strict. Dust masks belong to the first level in personal protective equipment, higher than earmuffs and protective glasses. The more authoritative testing certifications are European CE certification and American NIOSH certification.
