How do N95 masks catch particles that are smaller than the holes?

1. Particles are sticky because of static forces
2. Large particles go straight until they hit a mask layer
Tiny particles get knocked around by molecules until they hit a fibre
3. Fibres are given an electric charge so that they attract all particles (the mid-sized particles carrying the SAR2 virus need this)
