Indoor Air Quality

What is Asthma?

Asthma is a serious, sometimes life-threatening chronic respiratory disease that affects the quality of life for more than 25 million Americans, including an estimated 4 million children (EPA). Asthma can be controlled through different medications, such as an inhaler or breathing treatments.

Common Asthma Triggers 

Since Americans spend a lot of time in their home, indoor allergens and irritants can play a large role in triggering asthma attacks. Triggers are things that can cause asthma symptoms or an asthma attack. Some of the common asthma triggers you could find in your home and work to prevent in your home includes:

  • Secondhand smoke
  • Dust mites
  • Molds
  • Cockroaches and pests
  • Pets
  • Nitrogen dioxide
  • Outdoor air pollution
  • Chemical irritants
  • Wood smoke


The Healthy Homes Assessment include a visual walk-through and an assessment of the building and mechanical components. There will also be an evaluation of indoor air quality through measurements of: carbon monoxide (CO), carbon dioxide (CO2), temperature, and relative humidity. The Healthy Homes Assessment is also aligned with the eight principles of a healthy home, which includes keeping your home dry, clean, pest-free, ventilated, safe, contaminant-free, and maintained. An informal assessment of the asthmatic's respiratory condition will be made and Healthy Home/asthma-specific education will be shared with the program participant, as appropriate. If your child is the asthmatic, they are not required to be present during the Healthy Homes assessment, but if they are old enough to understand their medical condition, it is required.
