Protecting Yourself When Outside 

If you are in an area with poor air quality, it may be best to stay inside. If you go outside: 

• Avoid strenuous activity and try to reduce how much smoke you inhale. 
• Wear an N95 respirator mask. N95 respirator masks provide the best protection from wildfire smoke. Cloth masks will not help. 
• Only perform essential outdoor activities. Take frequent breaks indoors. 

Keeping Your Home’s Air Clean 

Make sure your indoor air is as clean as possible. 

Here's what you can do: 

• Consider purchasing a portable air cleaner — read these tips and avoid products that intentionally produce ozone. 
• Use a  do-it-yourself version if portable air cleaners are not an option. Watch a video to learn how to build a DIY air cleaner that can be used during wildfires and other emergencies. 
• Install a high-efficiency HVAC filter with a MERV-13 rating if your system can accommodate it. You may need to consult with an HVAC technician for guidance. 
• Adjust your HVAC system or air conditioner to keep smoke out. 
• Don’t create more indoor air pollution by doing things like smoking, vacuuming, frying or broiling meat, or burning candles or wood. 
• Consider creating a clean room in your home to keep levels of smoke and other particles as low as possible during smoke events.
