What's in Coeur D'alene's Air Right Now
PM2.5 (fine particles): 4 µg/m³. Anything under 12 µg/m³ counts as clean, so fine particles aren't a concern right now. These particles come from exhaust and smoke and are small enough to reach deep into your lungs.
PM10 (coarse dust): 5 µg/m³. Readings under 54 µg/m³ rate Good. Dust and pollen fragments ride in this size range and irritate your nose and throat.
Ozone: 103 µg/m³. Ozone forms when sunlight cooks car exhaust, so hot afternoons read worst, usually between 2 PM and 7 PM. Mornings stay cleanest.
Nitrogen dioxide: 0.7 µg/m³. NO2 comes almost entirely from traffic and feeds afternoon ozone. Readings run highest near busy roads during the morning and evening commutes.
Is It Safe to Go Outside in Coeur D'alene Today?

Days like this are worth using. If a long walk or a hard workout is on your list this week, today is the day for it.
Air Quality and Pollen Are Two Different Numbers
The air quality index tracks pollution: ozone, dust, smoke, and exhaust. Pollen isn't part of the score, so a Good air day in Coeur D'alene can still be a rough allergy day.
Right now the biggest pollen load in Coeur D'alene is grass pollen, rated Very High. If your eyes itch while the air reads clean, pollen is the likely culprit.
