Indoor Air Quality

During wildfire events, it is important to be aware of not only the air quality outside, but also the air quality in your home or in other buildings. Indoor air pollution can have both immediate and long-term health effects. That is why taking steps to reduce concentrations of indoor air pollution, including using air filtration and taking other air cleaning precautions, can help ensure that you are breathing in healthy air when you stay inside during wildfire events.    

The Environmental Protection Agency has provided the following recommendations for protecting your health and indoor air quality during a wildfire smoke event:

  • Consider purchasing a portable air cleaner for your home. Make sure that it does not produce ozone and that it is appropriately sized for the room you will use it in.
  • Install a high-efficiency HVAC filter, rated MERV 13 or higher, if your system can accommodate it. You may need to consult a professional HVAC technician to find the filter that will work best for your system.
  • Learn how to adjust your HVAC system or air conditioner to keep smoke out. For example, if your HVAC system has a fresh air intake, find out how to close it, or set the system to “recirculate.”
  • Learn about other potential sources of smoke and particles in your home, such as wood-burning stoves, fireplaces and candles, which pose potential risks to your lung and respiratory health. Avoid using these items during a wildfire smoke event.

If you have additional health-related questions regarding wildfire smoke, please contact Dr. Karl Musgrave with the Wyoming Department of Health at 307-777-5825.
