Why is a perfect fit so important for a mask?

To protect humans from a virus that is 0,01 to 0,03 microns in size, all possible leakage must be avoided. Sealing the mask to the face is crucial for two reasons. One is that the actual leakage that can let the virus in, the second is that a badly fitting mask will stimulate touching it to keep it in place.

Standard masks are designed as an average size that must fit most of the population. But of course no two faces are the same. We see big differences depending on race, gender and age. Standard ISO norm masks are designed based on standard dummy heads which are middle-aged Caucasian and male. A second more profound test can be done on a group of people, but this is not standard.

Therefore we believe that we have to look into the differences to find a new average that fits the people in care jobs. We believe that we need at least three sizes for perfect fits and will base these on an average of a real set of scanned faces. The mask then becomes a smart mask, using AI logic to build an average set of sizes.
