Works well

This respirator works very well for me. It prevents odors/smells and I can breathe easily through it. My asthma kicks in from most odors or smells which makes it hard to go anywhere. The mask helps me work or play outdoors or indoors without having to worry about not breathing and having to use medication that does not always work for me. It is fairly comfortable too. Not fond of the tight elastic bands but they make sure the mask does its job well. I purchase a couple of boxes at a time so I don't run out, plus the price is decent and shipment is timely.
