Pollen (size 1-150 μm) avoidance is difficult or impossible, but efforts to reduce exposure include closing windows and doors, using air conditioning and high-efficiency particulate air filters in the car and home, staying inside during the midday and afternoon when pollen counts are highest, wearing glasses or sunglasses, and wearing a face mask over the nose and mouth when mowing the lawn. In addition, consider increasing medications preseason and vacationing in a different ecosystem during pollen season.
