Do but allergy sufferers ever wear face masks just in case? Or do they not filter the particles sufficiently. Just think it may help sufferers.
I don't, I can sufficiently suppress my allergy with antihistamine tablets. I know there are some people that wear dust masks for that reason... but those don't cover the eyes and dust in the eyes will also lead to histamine release.
Dust from the ground peanuts in the carpet will generally stay low... but opening parcels of peanuts and moving them around (hey, you want to eat them!) spreads dust at breathing height.
