### FFP1 mask

FFP1 mask is that meet European (CE EN1409: 2001+A1:2009 ) standards.HOW DO c define bit mask WORK? Based on the tested particle transmission rate, there are three levels: P1 (FFP1), P2 (FFP2), P3 (FFP3). FFP1 Minimum filtering effect ≥80%，FFP2 Minimum filtering effect ≥94%，FFP3 Minimum filtering effect ≥97%. So FFP1 masks is the lowest level face mask.

### N95 mask

N95 is one of NIOSH's ratings for particulate filter respirator protection standards. "N" means Not resistant to oil, and "95" means the filtration efficiency is 95% or above. In addition to 95, there are classifications of N99 (the filtration efficiency is not less than 99%) and N100 (the filtration efficiency is not less than 99.97%),c define bit mask Wholesale Utimate Guide.

### FFP3 mask

FFP3 mask refers to masks that meet European (CE EN1409: 2001) standards. The standards of European protective mask are divided into three levels: FFP1, FFP2, FFP3. c define bit mask OF COVID-19,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.
