Can Poor Indoor Air Quality Increase Asthma Attacks?
Asthma, defined.
Asthma is a chronic respiratory disease that makes it difficult to move air in and out of the lungs. The condition causes inflamed airways that produce extra mucus, making it difficult to breathe. It can be developed at any age and is caused by genetics, respiratory infections, allergies, or the environment you were brought up in.
Due to increased sensitivity to the airways, asthma can be triggered by certain environmental conditions. Common triggers for asthma include the weather, dust in the air, chemicals, smoke, and pet dander.

Several common asthma triggers are indoor air pollutants or other IAQ-related conditions.
Indoor air pollutants consist of chemicals, particles and gasses that can be found within the air and make up your overall air quality. Recommended thresholds for these pollutants are housed under the EPA’s Air Quality Index (AQI), which is an aggregated measure of your air quality’s health based on five indoor air pollutantA Pollutant is a substance that contaminates air, water, or ...

IAQ-Related Conditions Linked to Asthma
High Particulate Matter Exposure
Particulate matter (PM) are tiny particles suspended in the air and are categorized by their diameter. The two distinctions are PM2.5 and PM10, whose diameters are less than 2.5 micrometers and less than 10 micrometers, respectively. PM2.5 is often referred to as fine dust particles, while PM10 is referred to as coarse dust particles. Both of which can be inhaled deep into the lungs causing adverse health risks.

For every 10-μg/m3 increase in PM2.5 measured indoors, there was a 7% increase in days of wheezing severe enough to limit speech and a 4% increase in days on which rescue medication was needed.

Indoor Smoking
Believe it or not, some public facilities still allow it – with casinos being the most prominent. Secondhand smoke contains particulates and chemicals that can be severely irritating to those with asthma. Exposure to these pollutants should be minimized for people with asthma, so it is important to ensure smoking and non-smoking rooms are kept separate.

- Ensure proper filtration performance. Upgrading to MERV-13 or the highest compatible filter class for your HVAC system will be more effective in reducing particulate matter.
- Monitor concentration levels. Indoor air quality monitoring is the best way to identify areas in your facility that need attention. With data from your monitors, you can pinpoint the source and resolve the issue.
- Use air purification solutions. Air cleaners that use HEPA filtration are highly efficient at cleaning the air of particulate matter.
- Hire a professional to provide air duct cleaning once every 2-5 years.
