FFP2 MASK RESPIRATOR CE CERTIFIED

FFP2 category masks refer to masks that meet European (CEEN1409: 2001) standards. The standards of European protective masks are divided into three levels: FFP1, FFP2, FFP3. It is different from the American standard in that it uses a detection flow rate of 95 L / min and uses DOP oil to dust.

The purpose is to prevent or reduce the dust in the air from entering the human respiratory organs to protect personal safety supplies.

It is composed of an anti-particulate mask mostly made of two layP2ers of non-woven cloth inside and outside, and a filter cloth (melt-blown cloth) in the middle; filtering dust mainly depends on the filter cloth in the middle, because the melt-blown cloth has its own electrostatic characteristics. It can adsorb very small particles. Since the fine dust is adsorbed on the filtering original, and the filtering original is static and cannot be washed, the self-priming filtering type anti-particulate respirator needs to replace the filtering original regularly.

The requirements for the use of anti-particulate masks are quite strict internationally. Anti-particulate 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, while Chinese standards are similar to American NIOSH.

The protection objects are divided into KP and KN. The so-called KP is able to protect oily and non-oily particles, while KN is only able to protect non-oily particles. China's protection levels are divided into KP100, KP95, KP90 and KN100, KN95, KN90. Among them, KP100 and KN100 have the highest filtration efficiency, and the national standard requires greater than 99.97%, so it is also the safest for use.
