The "masks" are defined Personal Protective Equipment (PPE) and are used to filter pathogens (viruses, bacteria and dust) from the air we breathe.
The greater the filtering factor, the greater the protection from pathogens, but also the greater the difficulty in inhaling.
PPE are classified into levels: FFP1, FFP2 and FFP3, (FFP stands for Filternig Face Pier, in Italian we can translate it with "filtering power") which indicate the filtering capacity.
The main difference between the 3 levels is in the filtering power of particles larger than 0.6 microns : (1 micron equals one thousandth of a millimeter!)
- the DPI FFP 1 -> filter at least 80%
- the DPI FFP 2 -> filter at least 94% (this model)
- the PPE FFP 3 -> filter at least 99%
It is correct to say that the following standards are equivalent to the European standard FFP2 :
- KN95 (China GB2626-2006)
- N95 (United States NIOSH-42CFR84)
- P2 (Australia / New Zealand AS / NZA 1716: 2012)
- Korea 1st class (Korea KMOEL - 2017-64)
- DS (Japan JMHLW-Notification 214, 2018)
