A wild guess - IIRC there are times when there is a high mold count in the  
air in some parts of Texas.
Molds produce mycotoxins. Mycotoxins change the way our bodies work, so  
the immune system might not be able to cope with something at those times.
I don't know if any filter would stop something presumably so small.
