As winter sets in, homeowners spend more time indoors to stay warm and comfortable. While heating systems provide relief from the cold, indoor air quality often declines during the season. The Environmental Protection Agency notes that indoor air can be several times more polluted than outdoor air, especially when homes are sealed tightly to conserve heat. Pollutants such as dust, pet dander, mold spores, and volatile organic compounds can accumulate, affecting comfort, respiratory health, and overall wellness. Staying proactive about indoor air quality ensures a healthier home environment throughout the winter months.
