Most other areas across the state are currently listed at MODERATE levels of air quality, including Cut Bank, Havre, Malta, Libby, and the Flathead Valley.

Here is an explanation from MT DEQ about the different categories:

• HAZARDOUS: All children and adults should avoid or limit all outdoor exertion
• VERY UNHEALTHY: Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion
• UNHEALTHY: Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
• UNHEALTHY FOR SENSITIVE GROUPS: Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion
• MODERATE: Unusually sensitive people should consider limiting prolonged outdoor exertion

When air quality is UNHEALTHY, people with heart or lung disease, smokers, children, and the elderly should limit heavy or prolonged exertion and limit time spent outdoors. People with asthma should follow their asthma management plan. People experiencing symptoms of heart or lung disease associated with smoke exposure should contact their healthcare provider.
