...Air Quality Alert through Saturday, July 18, 2026...

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued
an Air Quality Alert for July 17 and July 18, 2026, for elevated levels of fine particulate
due to wildfire smoke. Concentrations on Friday will range from Very Unhealthy in
southern areas to Hazardous in the north. On Saturday concentrations will range from
Unhealthy of Sensitive Groups (USG) in the south to Very Unhealthy in northern
portions of the state.

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 Saturday. The threat of increased
ozone may come into play Saturday as well.

Everyone should seek cleaner air indoors and keep activity levels low. While indoors,
take action to improve the indoor air quality such as:
- closing 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: burning
  candles, using vacuums without a HEPA filter, using gas stoves more
  than necessary, smoking, 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.
- Do not use masks for children under age 2.
