#DIY box fan filters – #CorsiRosenthal box "Also known as a Corsi-Rosenthal box, this DIY method of building your own air filter with #MERV13 furnace filters and a box fan are an easy and cost-effective way to help clear indoor air from airborne virus particles, wildfire smoke, pollen, dust, and more! If you can seal a box, you can build one (or 100!) of these!" https://cleanaircrew.org/box-fan-filters/ #OpenSource #CleanAir #CleanAirCrew #WildfireSmoke #WildfireHaze #AQI #AirQuality #ClimateDiary #WildfireSeason #Wildfires #HEPAFilters #CorsiRosenthalBox

Written back when the #US #EPA cared about #CleanAir! Do-It-Yourself #AirCleaners: Making Cleaner Air More Accessible Published September 6, 2023 "Everyone should have the right to breathe clean air. However, during wildfires, the cost and availability of clean air technologies and reliable power sources can create challenges for people trying to protect their health from wildfire smoke. Recognizing these barriers, EPA and other health, environmental, and nonprofit organizations have provided instructions and materials for creating do-it-yourself (#DIY) air cleaners. DIY air cleaners are a more affordable and accessible alternative to commercial versions and can be constructed using a box fan and a high-efficiency home air filter. Securing the filter to the fan creates an effective, simple air cleaning system. "This DIY solution filters out smoke particles and improves indoor air quality, but its use has raised key questions about the devices’ safety and effectiveness. EPA scientists and their colleagues are conducting research to answer these questions. " 'This research was highly anticipated, particularly by EPA’s western regions, who have suffered from terrible wildfire smoke for years without the ability to recommend more affordable air filtering options to the public,' noted Meredith Bauer, Assistant Director of EPA Region 9’s Air and Radiation Division. 'It is important that we develop tools that allow everyone to protect themselves and their families when wildfire smoke is in the air.'

#AirQuality plummets in #Boston, #Toronto as thick wildfire smoke shrouds the sky for millions Smoke from wildfires burning in Ontario have caused air quality to reach unhealthy levels across #Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve. By Brian Lada, Jul 15, 2026 Excerpt: "Toronto had some of the worst air quality in North America on Wednesday morning, reaching 'very unhealthy' levels with an AQI of 220. 'Health effects will be immediately felt by sensitive groups and should avoid outdoor activity,' Plume Labs said. 'Healthy individuals are likely to experience difficulty breathing and throat irritation.' "In Boston, air quality reached 'unhealthy' conditions on Wednesday morning with an AQI of 147. Little improvement is expected in the city into Thursday.
