they are worthless; when I mow the lawn I wear a mask during the worst of allergy season.
A real mask is hot AF in humid weather, tried these and suffered the usual sinus infection because they are worthless.
I've now realized if I flush my sinuses after mowing, no issues and no need to wear a mask.

This stuff I got in Moab is amazing! It totally flushes out everything!
