Is the Air Quality Good in Crow Wing, Minnesota?
Mostly — air quality in Crow Wing, Minnesota is fair, not pristine. The city earns a Grade of C (fair) on a 5-year median AQI of 36 (Good), with 15 unhealthy-air days over five years (about 3 per year). Healthy adults are fine most of the time, but sensitive groups should watch the daily forecast.
Who Can Safely Breathe the Air in Crow Wing, Minnesota?
Healthy adults can continue normal outdoor activity in most weather, but should pay attention to AQI alerts during the worst pollution windows. People with asthma, heart disease, or pregnancy should reduce prolonged or intense outdoor exertion on flagged days, and consider running an indoor HEPA air cleaner during peak season. Because PM2.5 penetrates deep into the lungs and bloodstream, an N95 or KN95 mask provides meaningful protection on smoky or high-particulate days — surgical masks do not.
Across the past five years, this area has logged just 15 days where AQI rose into the "Unhealthy for Sensitive Groups" range or worse — about 3 days per year, or roughly one every other month. That is a low count by national standards.

What's in Crow Wing, Minnesota's Air?
The dominant pollutant in Crow Wing, Minnesota is Fine Particulate Matter (PM2.5). Fine particulate matter — particles less than 2.5 micrometers across — comes mostly from combustion: vehicle exhaust, wildfire smoke, residential wood burning, and industrial emissions. Because these particles are small enough to enter the bloodstream, PM2.5 is the pollutant most strongly linked to cardiovascular disease, respiratory illness, and premature death.
Days by Dominant Pollutant (2023)
| Pollutant | Days as Dominant | Share of Year |
|---|---|---|
| Fine Particulate Matter (PM2.5) | 233 | 64% |
| Ground-Level Ozone | 132 | 36% |
Is the Air Getting Better or Worse?
Air quality in Crow Wing, Minnesota has been getting worse over the past decade, with median AQI climbing by roughly 0.4 points per year. That bucks the national trend of broad improvement, and most often reflects either growing wildfire smoke exposure (particularly across the West) or rising local emissions from population and freight growth.
In 2014, Crow Wing, Minnesota posted a median AQI of 35. By 2023 that figure was 43 — a rise of 8 AQI points dirtier across 10 years of EPA records.

How This Grade Is Calculated
The AirHistory Air Quality Grade combines four signals: the 5-year median AQI (40% of the score), the 10-year trend direction (30%), the count of unhealthy days per year (20%), and the dominant pollutant type (10%). All four come directly from the EPA Air Quality System (AQS), which aggregates readings from federally certified monitors. Read the full methodology.
