Question
My state has been impacted by the recent wildfires. It has significantly affected the air quality. How do I protect myself from having an asthma flare-up?
Answer

Wildfires cause poor air quality. You can do several things to protect yourself from an asthma flare-up. This includes:

  1. Stay indoors and limit outdoor activities, especially exercise. This can reduce your exposure to smoke and particulate matter.

  2. Access and use air quality alert websites, such as AirNow. You can monitor air quality in your area.

  3. Use high-efficiency particulate air (HEPA) filters in portable air cleaners or HVAC systems to reduce indoor particulate matter levels.

  4. Keep windows and doors closed. This will prevent outdoor air from entering. Use air conditioning in recirculation mode to maintain a clean indoor environment.

  5. If you must go outdoors, wear an N95 face mask. This can provide some protection against inhaling fine particulate matter. Standard masks like surgical masks or cloth masks offer limited protection.

  6. Avoid activities that can increase indoor air pollution. This includes burning candles, using fireplaces, and cooking with solid fuels.

  7. If available, consider going to public buildings with central air conditioning and HEPA filters (such as an indoor shopping center or library) when air quality is poor from wildfires and other sources.

  8. Be prepared to evacuate your area if advised. Have an emergency kit ready to go including all your medicines.

  9. Follow your Asthma Action Plan. Follow up with your doctor as needed.
