The holder is comprised of upper and lower flange walls in which are mounted filter members having a mesh size to pass air but not pollen, with additional filters being positioned between the walls at the sides thereof. Also mounted between the flange walls at the front is a viewing lens. A protective cloth impermeable to pollen can be secured to the lower flange wall and extends downwardly over the mouth and around the neck of the user to permit inhalation through the mouth.
