Keep windows closed during pollen season

What to Do

Keep home and car windows closed during your allergy season, especially on high-pollen days and during early morning hours. Use air conditioning instead of open windows for ventilation.

Why It Works

Open windows allow pollen to enter and settle on indoor surfaces, furniture, and bedding. Studies show indoor pollen levels correlate directly with window-opening habits. Air conditioning filters some pollen and dehumidifies the air, creating a less hospitable environment for dust mites as well.

Tips

• Use the recirculate setting on car AC to avoid pulling in outside air
• If you must open windows, do so in the late afternoon when pollen counts drop
• Window screens reduce but do not eliminate pollen entry
• Consider a window fan with a HEPA filter attachment if you prefer fresh air circulation
