What differences among FFP1, FFP2, and FFP3 mask?

Most of our competitors have chosen to develop a HALF MASK, which has a larger size on the face as it goes under the chin but has a larger filtration area.
P1, P2, P3, what differences?
We talk about FFP for disposable masks and FMP for reusable masks. Levels P1, P2, and P3 for these two categories correspond to the same requirements. The levels vary according to the rate of Total Internal Leakage (FTI), this means the quantity of air that does not pass through the filter and which is therefore not filtered, and the Penetration rate (or rate filtration) of the filter media. This means the% of particles retained by the device.

Classifications require the following results:
FFP1 or FMP1 = Filtration: 80% minimum. Internal leakage rate: 22% maximum
FFP2 or FMP2 = Filtration: 94% minimum. Internal leakage rate: 8% maximum
FFP3 or FMP3 = Filtration: 98% minimum. Internal leakage rate: 2% maximum
Only a mask with a perfectly waterproof structure and an extremely impervious filter (hardly breathable) can reach level P3.
Having a P3 mask means that the breathing effort is going to be very important. Thus, in the event of a leak in the face, the non-sealed anti-pollution mask represents a danger. Indeed, the user will breathe harder, which will promote the entry of fine particles.
