As the weather cools down, we begin to spend more time indoors with our windows shut, trying to keep the warmth inside. While this helps conserve heat, it also traps pollutants, allergens, and moisture that can lower indoor air quality (IAQ). Poor air quality can lead to respiratory issues, allergies, and even impact the efficiency of your HVAC system.

Before winter fully sets in, now is the perfect time to get ahead of the problem. Here’s how you can ensure clean, healthy indoor air this fall and winter.

1. Start with Fresh HVAC Filters

Changing your air filter is one of the easiest and most effective ways to improve indoor air quality. Over time, filters collect dust, pollen, pet dander, and other airborne particles. If not replaced regularly, clogged filters reduce airflow, forcing your HVAC system to work harder and spreading contaminants throughout your home.

  • How often should you change filters?
    Every 30 to 90 days, depending on the filter type and household conditions (e.g., pets, allergies).

2. Schedule Duct Cleaning

Your ductwork can accumulate dust, dirt, mold spores, and allergens over time. When your HVAC system kicks on, these contaminants are circulated throughout your home. A professional duct cleaning can improve airflow, prevent allergens from spreading, and enhance the efficiency of your HVAC system.

  • When to consider duct cleaning:
    • If it has been 3-5 years since the last cleaning.
    • If there are signs of mold, dust buildup, or pest infestations inside the ducts.
    • If family members experience allergies or respiratory issues indoors.

3. Use a Whole-House Air Purifier or UV Light

If you want extra protection, installing an air purifier or UV light inside your HVAC system can make a noticeable difference. Air purifiers filter out fine particles, bacteria, and viruses, while UV lights kill harmful microorganisms like mold and bacteria circulating in your air.

  • Benefits of whole-house air purifiers:
    • Removes smoke, pollen, and pet dander.
    • Helps those with allergies, asthma, or other respiratory conditions.
    • Improves airflow by keeping HVAC components clean.

4. Check for Proper Ventilation

Good ventilation is essential for maintaining healthy IAQ, especially during the colder months when homes are sealed tightly. Poor ventilation can cause moisture buildup, leading to mold growth, stale air, and indoor air pollution.

  • Tips to ensure proper ventilation:
    • Open vents and make sure they are not blocked by furniture.
    • Use exhaust fans in kitchens and bathrooms to reduce moisture.
    • Consider installing an energy recovery ventilator (ERV), which exchanges stale indoor air for fresh outdoor air while maintaining energy efficiency.

5. Control Humidity Levels with a Humidifier

During the winter, dry air can cause issues like dry skin, nosebleeds, and increased static electricity. Low humidity also impacts IAQ by irritating your respiratory system. Running a whole-house humidifier can help keep humidity levels between 30% and 50%, the ideal range for indoor comfort.

  • Bonus: Proper humidity levels can also help preserve wood furniture and reduce energy bills since humid air feels warmer.

6. Clean Your Air Vents and Registers

Dust and debris often accumulate on the surface of vents and registers, impacting air quality. Give these areas a quick clean before winter arrives.

  • How to clean vents and registers:
    1. Remove the vent covers and wash them with soapy water.
    2. Use a vacuum with a hose attachment to remove dust inside the ducts.
    3. Wipe the inside edges with a microfiber cloth.

7. Add Houseplants to Your Space

Plants are a natural way to enhance indoor air quality. Certain species are known for their ability to filter harmful chemicals from the air, such as benzene, formaldehyde, and carbon monoxide. Plus, they add a cozy touch to any room during the colder months.

  • Top air-purifying plants for winter:
    • Snake Plant
    • Peace Lily
    • Spider Plant
    • English Ivy

Conclusion

Improving your indoor air quality before cold weather sets in ensures you and your family breathe easier all season long. From replacing filters to scheduling duct cleanings, these small steps can make a big difference in your health and comfort. If you want to take it further, consider adding air purifiers or humidity control systems to your HVAC setup.
