We have been using Halo Face Masks for some time. They fix many of the problems we see in face masks. They have a rubber foam insert that goes around the nose which prevents slippage and prevents glasses from fogging. The ear straps are adjustable. The replacement filters were originally designed to filter smoke in New Zealand so their particulate filtrations is extremely high as smoke is a very small particle.
