And maybe Covid-19, too

If you live on America’s West Coast, you’ve probably bookmarked the air quality monitoring website PurpleAir by now.

Wildfire smoke isn’t just a nuisance, either — it’s a killer. As the San Francisco Chronicle reports, smoke from 2020’s wildfires has likely already killed 1,200 to 3,000 people.

Faced with a major yearly fire season and knowing the dangers of wildfire smoke, I wanted to find out how to keep my family safe. As a Californian and a technologist, I decided to find out what gadgets and technologies could help me reduce air pollution in my home.

The Environmental Protection Agency (EPA) says that “fine inhalable particles” — those that are smaller than 2.5 microns, or 30 times…
