Nah, "better hygiene" is completely anathema to people wearing damp cloth on their faces. The sorts of things people are wearing are completely useless against dust an pollution too.
Honestly, the mask thing is just a placebo to make people "feel safer", as
@Peter Sarf mentions above. The home-made, designer fabric and surgical masks people are wearing would be illegal and completely ineffective to use when working with something like asbestos, or even non-hazardous dusts in the workplace. Why people believe they can trap viruses, which are far smaller than physical dusts is beyond me. Fact 95% or more of your breath when wearing a non face-fitted mask is escaping around the sides - that's why glasses steam up when wearing the stupid things.
