Indoor Air Quality Gets Worse During the Holidays: Here are 6 Simple Fixes

The holidays bring family, food, and festive cheer, but all that activity can quietly impact something you might not think about: your home’s indoor air quality (IAQ). Even in warmer climates like Florida, the combination of cooking, heating, guests, and seasonal decor can make your indoor air stuffy, dry, or even unhealthy.

Poor air quality can cause headaches, fatigue, allergy flare-ups, and general discomfort, which is not exactly the mood you want during family celebrations. With a little planning, you can maintain fresh, clean air inside your home throughout the holiday season.

Here’s why IAQ tends to drop during the holidays, and six simple fixes you can implement today.

Why Indoor Air Quality Tends to Get Worse During the Holidays

Cooking More Often Releases More Particles in the Air

Holiday meals often involve hours of frying, roasting, baking, and simmering. All that cooking releases smoke, grease particles, and moisture into the air. Without proper ventilation, these particles linger, leaving your home feeling stuffy and greasy, and sometimes even setting off smoke alarms unnecessarily.

Fix: Use exhaust fans or open windows while cooking. Consider utilizing a portable air purifier with a HEPA filter in the kitchen to capture fine particles.

Hosting Leads to Higher Humidity and More CO₂

When you host friends and family, your indoor environment changes quickly—more people = more humidity, carbon dioxide, dust, and allergens. Warm air from body heat also makes your HVAC system work harder, which can reduce its efficiency in filtering the air.

Fix: Run your HVAC fan on “ON” mode instead of “AUTO” to continuously circulate and filter air. Adding a few small portable air purifiers in guest-heavy areas helps keep the air fresh.

Holiday Decor Can Trap Dust and Allergens

Seasonal decorations, from Christmas trees to wreaths and garlands, can trap dust, pollen, or mold spores. Real trees, in particular, can carry outdoor pollen and sap indoors, which may aggravate allergies or respiratory issues.

Fix: Dust decorations before placing them, vacuum around trees frequently, and consider using artificial trees if allergies are a concern.

Candles, Fireplaces, and Scented Oils

Candles, fireplaces, and scented essential oils may make your home smell amazing, but they also release particulate matter and VOCs (volatile organic compounds) that can irritate your lungs and worsen air quality.

Fix: Burn candles and use essential oil diffusers in well-ventilated areas and avoid overusing them. Limit fireplace use to when it’s truly needed for warmth. A small air purifier nearby can help capture some of the airborne particles.

HVAC Filters Get Overworked

With more activity, cooking, and guests, your air filters can become clogged faster, reducing airflow and making your HVAC system less efficient. Dirty filters can circulate dust, allergens, and odors instead of removing them.

Fix: Check and replace your air filters before the holiday season and consider high-efficiency filters for the winter months.

Dry Winter Air

Even in Florida, cooler temperatures combined with indoor heating can dry out your air, making it feel stuffy and uncomfortable. Dry air can aggravate your skin, sinuses, and throat, and it also increases dust circulation.

Use a humidifier in rooms where you spend the most time. Keeping indoor humidity between 40–50% is ideal for comfort and air quality.

Tips for Keeping Holiday Air Fresh

• Open windows briefly when outdoor temperatures are mild.
• Schedule a professional HVAC tune-up with Parker Services before the holidays.
• Urge guests to remove shoes at the door to reduce tracked-in dust.
• Keep indoor plants in strategic locations—some varieties naturally filter air.
