During the winter months, many homeowners notice an increase in allergy symptoms, dry skin, and lingering odors inside their homes. This isn’t just a coincidence—indoor air quality often worsens when temperatures drop. The main culprit is reduced ventilation. With windows and doors closed to keep the cold out, fresh air has fewer opportunities to circulate, trapping pollutants, allergens, and moisture inside.
Heating systems can also contribute to the issue. Forced-air furnaces, especially if they haven’t been getting proper heating maintenance, can circulate dust, pet dander, and other airborne particles throughout your home. Additionally, lower humidity levels in winter can make the air feel drier, irritating the respiratory system and exacerbating conditions like asthma and allergies.
Common Pollutants That Build Up in Winter
Several indoor air pollutants become more concentrated during the winter months:
- Dust and Allergens:With less airflow, dust mites, pet dander, and mold spores accumulate, making allergies worse.
- Volatile Organic Compounds (VOCs): Cleaning products, candles, and off-gassing from furniture or carpets contribute to poor air quality.
- Carbon Monoxide (CO): Heating systems, fireplaces, and gas stoves can produce carbon monoxide, a dangerous gas that’s difficult to detect without a CO alarm.
- Mold and Mildew: Condensation from temperature differences can create moisture buildup, leading to mold growth in basements, bathrooms, and poorly ventilated areas.
Ways to Improve Indoor Air Quality in Winter
Maintaining healthy indoor air during the colder months is possible with a few proactive steps:
- Change Your Air Filters Regularly: A clogged HVAC filter recirculates dust and allergens. Swapping it out every one to three months keeps your system running efficiently and improves air quality.
- Use a Humidifier: Dry air can cause discomfort and make it easier for airborne particles to spread. A humidifier helps maintain a comfortable moisture level.
- Improve Ventilation: While it’s not practical to leave windows open in the middle of winter, using exhaust fans, air purifiers, and whole-home ventilation systems can help freshen the air.
- Schedule a Professional HVAC Inspection: Your heating system plays a big role in indoor air quality. A professional tune-up keeps it running cleanly and safely.
