Save Your Mask for the Next Disaster

posted by Jason Kottke   Jul 22, 2021

In what will be an increasingly common occurrence in the years to come, smoke from fires in the western United States and Canada covered a large part of the US over the past few days. The smoke drifted thousands of miles to the eastern seaboard and turned the skies hazy, the Sun orange, and the air dangerous for some people to breathe. But there’s good news: your Covid mask works for air pollution too!

Dr. Commane said people should avoid going outdoors in high-pollution conditions, and especially avoid strenuous exercise. She also suggested that wearing filtered masks can provide protection for those who can’t avoid the outdoors.

“A lot of the masks people have been wearing for Covid are designed to capture PM2.5,” she said, referring to N95-style masks. “That’s the right size to be very useful for air quality.”

It’s always nice when your apocalyptic dystopias match up so nicely.
