What kinda mask are you using?
I have a buncha pm 2.5 cycling masks with replaceable filters. Occasionally I end up in moldy basements or dusty attics. They have exhalation valves but I have covered them for this use.
Research says that a pm 2.5 filter is nearly as good as n 95 if used properly. The filters have 2 layers of meltblown fabric, 2 layers of nonwoven cotton, and activated charcoal. The strap around design gives a tighter (if slightly less comfortable) fit to reduce or eliminate leakage around the edges.
What's yours?
