This one came to me via a friend. Western OR and parts of CA clocked around 700ppm over the weekend, which goes well beyond the EPA’s air quality scale that tops out at 500ppm (“hazardous”).
How are people dealing with this? I’m near SF where levels have been around 200 ~ 250ppm and it’s been just miserable—and I have respirators and air purifiers handy!
