Surviving Smoke and Ash

  • Use an AQI app on your phone to notify you when the air gets gross.
  • When the AQI goes above 150, avoid going outside.
  • Consider sealing windows and filtering the air in your home.
  • When you have to go outside, wear a mask rated N95 or better (ideally P100).
  • Your mask must fit perfectly or it’s useless.
  • If it’s often smoky where you live, get a permanent mask.
  • Consider planning for a power cut.
