Any recommendations for dust and organic fumes masks for those of us with beards? I do not have a full beard, but am where a normal dust mask covers. I seem to get more air through my beard then the mask. This means I need to vacuum my beard after taking the mask off (ya, I am sure it looks funny). And I am sure I am getting plenty of dust past the beard. I can just imagine the organic fumes. So before I plunk down $50 on a real mask, I would want know it will work, short of shaving the beard.
