Elizabeth –
I have severe allergies from all airborne pollutants. I have found the Respro masks are great for protecting me from breathing in smoke, chemical smells, vehicle emissions, all scented products., pollen, mold and anything that may be in the air. I have environmental illness and these masks, with the chemical and particle filters provide me with great protection, when protection from heavy pollutants is greatly needed.
