How to improve air quality for fall allergy season

Fall in Madison Heights brings cool air, colorful leaves, and—unfortunately for many—seasonal allergies. Ragweed pollen, mold spores, and dust can sneak into your home and make life miserable. The good news? Your HVAC system is one of the best tools you have to keep your air clean and your sinuses clear.

Here are some simple but powerful steps you can take to improve indoor air quality this fall.

1. CHANGE YOUR AIR FILTER REGULARLY

Your air filter is the front line of defense against dust, pollen, and other airborne irritants. A clogged filter can’t do its job, and it forces your furnace or AC to work harder. Replace your filter every 1–3 months in the fall, especially if you have pets or allergy sufferers at home.

2. UPGRADE TO A HIGH-EFFICIENCY FILTER

If you’re using a standard fiberglass filter, consider switching to a pleated filter with a higher MERV rating. These filters trap smaller particles like pollen, mold spores, and pet dander, giving you cleaner, healthier air.

3. ADD AN AIR PURIFIER OR UV LIGHT

For next-level protection, talk to your HVAC professional about whole-home air purifiers or UV lights. These systems work with your existing HVAC setup to kill bacteria, neutralize mold, and remove microscopic allergens before they circulate through your home.

4. KEEP YOUR DUCTS CLEAN

Over time, dust and allergens collect inside your ductwork. If it’s been years since you’ve had them inspected, fall is a great time to schedule a professional cleaning. Clean ducts mean cleaner air and a more efficient heating system.

5. CONTROL HUMIDITY LEVELS

Fall weather can bring swings in humidity that impact your comfort and health. Too much moisture encourages mold, while overly dry air can irritate your sinuses. A whole-home humidifier or dehumidifier keeps your indoor air balanced and allergy-friendly.
