How do masks help with allergies?
Masks work in the same way that air purifiers work. Masks filter out airborne particles and allergens. Depending on the type of mask, the filter can protect against irritants like cleaning agents, perfumes, soaps, paint, varnish, hydrocarbon pollution, arsenic, odors, and chemical air fresheners. An allergy mask will be able to provide protection against common allergens like pollen, plant spores, pet dander, mold, cigarette smoke, house dust, and dust mites.
