If you are heading out, wearing a mask is mandatory, not because of the law, but because it has become a basic necessity to be safe from air contaminants. The common advice given out is to use either a disposable dust mask or a disposable respirator mask to get the best face protection without any risk of contamination. Disposable masks are meant for only one-time use and should be instantly disposed of as soon as you take them off your face. Buy high-quality disposable masks at the Respirator Shop now!
