Aug 14, 2026, 6:03 PMThe worst air quality in the world? Chilliwack and Sunshine Valley AQI > 300, Hozomeen AQI reaching 3000. [1]
For scale, 3000 ug/m3 is hundreds of times the recommended limit:
The EPA is setting the level of the primary (health-based) annual PM2.5 standard at 9.0 micrograms per cubic meter (μg/ m3) [2]
Awful, terrible, no-good air.
Wear a mask! Run air purifiers! Trust your nose if you smell smoke, and your eyes when you see haze!
