BILLINGS, Mont. (AP) — Health officials warned Montana residents to protect themselves from smoke pollution on Monday as the air quality deteriorated to unhealthy levels across much of the state.
The pollution was at concentrations high enough for officials to recommend that people limit outside activities in communities including Bozeman, Dillon, Frenchtown, Seeley Lake and Broadus.
Air quality considered harmful to sensitive groups — such as people with lung disease or asthma — was reported in Missoula, Butte, Billings, Helena, Great Falls, Lewistown and several smaller cities.
The worst air quality was concentrated in areas of Montana south of Interstate 90, officials said
N95 respirators can protect against wildfire smoke but need to fit properly to be effective.
