Don't mistake a dust mask for a respirator. Respirators work as dust masks but dust masks do not work as respirators. The problem you describe is common with dusk masks and is solved by Lucy's suggestion. This problem, in my experience. doesn't happen with respirators as they have a totally different strap design.
