Wildfire Smoke Is Affecting Michigan's Air Quality: Here's How to Protect Yourself

Smoke from ongoing Canadian wildfires has created hazardous air quality conditions across Michigan, prompting statewide air quality alerts. While the smoke may look like fog or haze, it contains tiny particles and gases that can travel hundreds of miles and affect your health—even if the fires are nowhere near your community.

Whether you're spending time outdoors, commuting to work, or simply wondering if it's safe to open your windows, understanding how wildfire smoke affects your health can help you protect yourself and your family.

Why Is the Air Quality So Poor?

Wildfire smoke contains a mixture of gases and microscopic particles known as fine particulate matter (PM2.5). These particles are small enough to travel deep into the lungs and even enter the bloodstream, increasing the risk of respiratory and cardiovascular problems.

According to the Michigan Department of Environment, Great Lakes, and Energy (EGLE), smoke from Canadian wildfires has pushed air quality across Michigan into the Hazardous category, with conditions expected to continue into the coming days.

Who Is Most at Risk?

Although everyone should limit exposure during heavy smoke events, some people are more likely to experience health problems, including:

  • Children and teenagers

  • Adults age 60 and older

  • People with asthma, COPD, or other lung diseases

  • People with heart disease

  • Pregnant individuals

  • Outdoor workers

  • Anyone exercising or performing strenuous activities outdoors

Symptoms of Wildfire Smoke Exposure

Breathing wildfire smoke can cause:

  • Eye irritation

  • Burning nose or throat

  • Coughing

  • Wheezing

  • Shortness of breath

  • Chest tightness

For people with asthma or heart disease, smoke exposure can trigger serious flare-ups and may require medical attention.

How to Protect Yourself

When air quality reaches unhealthy or hazardous levels, the best protection is to reduce your exposure.

Stay Indoors

Whenever possible:

  • Keep windows and exterior doors closed.

  • Avoid bringing outdoor air inside.

  • Limit activities that worsen indoor air quality, such as burning candles, smoking, or vacuuming without a HEPA filter.

Improve Indoor Air Quality

If you have air conditioning:

  • Run your system on recirculate if possible.

  • Use a MERV-13 or higher HVAC filter if your system supports it.

  • Portable HEPA air cleaners can also help reduce smoke particles indoors.

Avoid Strenuous Outdoor Activity

Even healthy adults breathe more deeply during exercise, increasing the amount of smoke that reaches the lungs.

If you need to be outside:

  • Keep outdoor time as short as possible.

  • Avoid vigorous exercise or heavy physical work.

  • Consider wearing a well-fitting NIOSH-approved N95 or P100 respirator if you must be outdoors for extended periods. Cloth masks and surgical masks do not effectively filter wildfire smoke particles.

Check Air Quality Before Heading Outside

Air quality can change throughout the day and vary by location.

Before spending time outdoors, check current conditions using:

If You Have Asthma or Heart Disease

People with chronic medical conditions should take extra precautions.

  • Continue taking prescribed medications.

  • Keep rescue inhalers readily available.

  • Follow your healthcare provider's action plan.

  • Contact your healthcare provider if symptoms worsen during periods of poor air quality.
