Remain indoors in the morning when the pollen levels are highest. Sunny, windy days can be especially bothersome for allergy sufferers. If you have a pollen allergy and you must work outdoors, you can wear tight fitting face masks that are designed to filter pollen out of the air before it reaches your nasal passages.
Keep your lawn mowed to prevent grasses from blooming and pollinating. When you do mow your grass, wear a mask to filter out the pollen particles.
When you are in your car, keep your windows closed and your air conditioning on re-circulate.
At home keep your windows closed during peak hours of the day, and be sure to replace your heating/cooling air filters regularly.
Obtain a High Efficiency Particulate Air (HEPA) filter. They are very effective in removing pollen from the air indoors without contaminating the environment with molds.
Pets bring in pollen on their fur. Brushing them thoroughly before they come in will keep them from “tracking” pollen inside.
