Air Quality Alert issued July 16 at 12:13PM EDT by NWS Marquette MI

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Alert for July 16 and July 17 2026, for elevated levels of fine particulate due to wildfire smoke. Concentrations will be in the Hazardous range.

This is a Statewide Air Quality Alert.

Plumes of smoke from Canadian wildfires continue to drift across the region. Elevated fine particulate due to the smoke will continue through Friday.

Everyone should see cleaner air indoors and keep activity levels low. While indoors, take action to improve the indoor air quality such as:

• Close windows and minimize opening of doors.
• If HVAC systems are not equipped with MERV-13 filters or higher, use portable air cleaners.
• Avoid activities that make indoor air quality worse such as burning candles, using vacuums without a HEPA filter, using gas stoves more than necessary, smoking, and spraying aerosol products.

If you must be outdoors for short periods of time:

• Wear an N95 or P100 respirator marked with NIOSH. The respirator should fit tightly, collapse as you breathe in and not let air in from the sides.
• Instructions for fitting a respirator mask properly can be found at https://www.epa.gov/sites/default/files/2018-11/documents/respiratory_protection- no-niosh-5081.pdf
• Do not use masks for children under age 2.
