You don't have to smell smoke for it to affect you.
This photo was taken in Calgary this morning. The smoke smell was barely noticeable, but the air quality was still poor. Our senses aren't a reliable indicator of what's in the air.
Wildfire smoke contains tiny particles (PM2.5) that can travel deep into your lungs, even when the air doesn't seem smoky.
On days like this:
⢠Keep windows and doors closed.
⢠Run a quality air purifier or your home's fan with a high-efficiency filter.
⢠Limit strenuous outdoor activity if air quality is poor.
⢠Pay extra attention if you have asthma, COPD, heart disease, young children, or older adults at home.
Your lungs don't care whether you can smell the smoke. They only know what you're breathing.
