It is important to regularly clean and maintain heating systems to ensure good air quality and to minimize the impact on your health. Using a humidifier can also help to improve air quality and reduce the drying effects of heating systems. **

Air quality worsens in humid weather because the moisture in the air can trap pollutants and prevent them from dispersing. This can lead to an accumulation of pollutants such as dust, pollen, and mold spores, which can degrade air quality. Additionally, high humidity can also promote the formation of ground-level ozone, a harmful pollutant that can exacerbate respiratory issues. Finally, humid weather can also create conditions that are conducive to the growth of bacteria and other microorganisms, further contributing to poor air quality. **
