As i said up their medical masks work, i know i have a box of them at home.
At the spore don't really like heat so they can be reusable. Most of the times the spores won't float around. they will find something to settle on. medical mask would deflect the spore which only take hold to organic materials. so the medical mask would just deflect them.
