Indoor air quality (IAQ) fluctuates throughout the year and is influenced by temperature, humidity, and outdoor pollutant changes. As the seasons shift, different environmental factors affect the air inside homes and businesses, potentially impacting health and comfort. Understanding these seasonal changes can help you proactively maintain clean and healthy indoor air.

1. Spring: Pollen and Allergens

Spring brings higher levels of pollen, dust, and airborne allergens, which can enter indoor spaces through open windows, HVAC systems, and clothing. This can trigger allergies and respiratory issues. To combat this:

  • High-efficiency air filters in HVAC systems are used to trap pollen.
  • Keep windows closed on high pollen days and use air purifiers.
  • Clean and vacuum frequently to reduce indoor allergens.

2. Summer: Heat and Humidity

High humidity levels can create an ideal environment for mold, mildew, and dust mites during the summer. Poor ventilation can also lead to stale air and increased indoor pollutants. Key prevention steps include:

  • Using dehumidifiers to maintain indoor humidity below 50%.
  • Ensuring proper ventilation in bathrooms and kitchens.
  • Cleaning air ducts and replacing HVAC filters regularly.

3. Fall: Mold and Decaying Organic Matter

As leaves decay and temperatures fluctuate, mold spores and organic matter can enter indoor air. This is also when many homeowners use heating systems, which can stir up dust and pollutants. To improve IAQ in the fall:

  • Schedule HVAC system maintenance before the heating season.
  • Clean gutters and remove fallen leaves to reduce mold buildup.
  • Check for leaks and moisture buildup in basements and attics.

4. Winter: Indoor Pollutants and Stagnant Air

Winter often means closed windows and reduced ventilation, leading to a buildup of indoor pollutants such as carbon monoxide, volatile organic compounds (VOCs), and dust. Dry air can also worsen respiratory conditions. Improve winter air quality by:

  • Using humidifiers to balance indoor moisture levels.
  • Keeping furnaces and fireplaces well-maintained to prevent CO buildup.
  • Ventilating regularly by opening windows briefly when outdoor air quality allows.

How to Maintain Healthy Indoor Air Year-Round

To ensure optimal indoor air quality throughout the year:

  • Regularly inspect and clean HVAC systems to prevent dust and pollutant buildup.
  • Invest in air purifiers with HEPA filters to remove airborne contaminants.
  • Monitor indoor humidity levels to prevent mold and dust mite growth.
  • Schedule professional air quality testing to identify hidden pollutants.
