When temperatures drop, most of us spend more time indoors, relying on our heating systems to stay warm. But winter often brings air quality challenges, from dry air to increased dust, allergens, and airborne contaminants. Fortunately, indoor air quality services and products can help you create a healthier home environment during the colder months.
If you’re wondering how to improve indoor air quality in winter, this guide covers the key factors affecting air quality and the best solutions to maintain fresh, clean air in your home.
The Impact of Heating Systems on Indoor Air Quality
Your heating system plays a significant role in indoor air quality during winter. While it keeps your home warm, it can also circulate dust, pet dander, mold spores, and other pollutants—especially if the system isn’t properly maintained. Furnaces and heat pumps also contribute to dry indoor air, which can cause respiratory discomfort, dry skin, and an increase in static electricity.
Common indoor air quality concerns during winter include:
- Dust and allergens: Without proper filtration, heating systems can spread airborne particles throughout your home.
- Low humidity levels: Cold air holds less moisture, and running your heat can dry out the air even more, leading to irritated sinuses, dry skin, and an increased risk of illness.
- Poor ventilation: Keeping windows and doors tightly closed to conserve heat can trap pollutants inside, leading to stale indoor air.
- Increased carbon monoxide risk: Gas furnaces and fireplaces can produce carbon monoxide (CO), which can be dangerous if ventilation is inadequate.
How to Improve Indoor Air Quality in Winter
Whether you’re dealing with dry air, allergies, or stagnant indoor air, the following strategies can make a big difference.
1. Upgrade Your HVAC Filters for Better Air Filtration
One of the easiest ways to improve indoor air quality is by using high-efficiency air filters in your HVAC system. Standard filters trap larger dust particles, but if you want to remove finer allergens like mold spores and pollen, consider upgrading to:
- HEPA filters: Capture up to 99.97% of airborne particles, including dust, pet dander, and allergens.
- Electrostatic filters: Use static electricity to attract and trap small particles more effectively than basic fiberglass filters.
- Activated carbon filters: Help eliminate odors, smoke, and chemical pollutants in the air.
Replacing your air filter every one to three months helps maintain optimal air quality and HVAC efficiency.
2. Maintain Proper Humidity Levels with a Humidifier
If the air in your home feels dry, a whole-home humidifier can restore comfortable moisture levels. Proper humidity, ideally between 30-50%, helps prevent:
- Dry, itchy skin and irritated sinuses
- Increased susceptibility to colds and respiratory issues
- Cracks in wood furniture and floors
If you have noticed these signs in your household, consider buying a humidifier. A humidifier works with your HVAC system to evenly distribute moisture, improving comfort while protecting your home from winter dryness.
3. Schedule Routine HVAC Maintenance
Regular HVAC maintenance is essential for keeping your heating system running efficiently and improving indoor air quality. A professional technician can:
- Clean and inspect air ducts to remove dust buildup and mold growth
- Check for leaks or blockages that could impact airflow
- Ensure proper ventilation to reduce carbon monoxide risks
- Replace worn-out filters and recommend air purification solutions
Scheduling bi-annual HVAC maintenance can help prevent contaminants from circulating through your home and maintain good air quality all year long.
4. Improve Air Circulation and Ventilation
While it’s tempting to keep your home sealed tight during winter, fresh air is essential for maintaining good indoor air quality. Since opening windows isn’t always practical, consider these options:
- Use ventilation fans in kitchens and bathrooms to remove excess humidity and pollutants
- Install an Energy Recovery Ventilator (ERV) to bring in fresh air without losing heat
- Let in fresh air on mild days by briefly opening a window to allow stale air to escape
Proper ventilation helps reduce indoor air pollutants and keeps your home feeling fresh during winter.
5. Invest in an Air Purification System
For the best possible air quality, an air purifier can remove a wide range of airborne contaminants. There are several types of air purifiers to choose from:
- HEPA Air Purifiers: Trap microscopic pollutants, including allergens and bacteria
- UV-C Light Purifiers: Kill germs, viruses, and mold spores
- Activated Carbon Purifiers: Reduce odors, VOCs, and chemical pollutants
If there are pets or allergy sufferers in your household, consider purchasing an air purifier. When paired with your HVAC system, an air purifier can improve indoor air quality and provide relief for those with sensitivities to airborne allergens.
6. Test for Carbon Monoxide (CO) and Radon
Carbon monoxide (CO) and radon are two odorless, invisible gases that can pose serious health risks if left undetected.
- Install CO detectors near sleeping areas and fuel-burning appliances
- Have your furnace checked annually for proper ventilation and CO leaks
- Test for radon levels using a home test kit or professional service, as radon is a leading cause of lung cancer
Proper monitoring of these gases is essential for maintaining a safe indoor environment.
