Breathe Safely: Prepare for Wildfire Smoke and Air Quality Challenges

The following strategies can be used to reduce exposure to wildfire smoke and dangerous air pollutants.

Stay Indoors:

• Indoors offer some smoke protection, especially in closed, air-conditioned homes with recirculated air.
• Keep windows and doors shut to minimize outdoor air entering.
• If without AC, seek shelter in air-conditioned places like family, neighbors, or public buildings with filtration during smoky times to cool off daily.

Reduce Activity:

• Less activity reduces inhaled pollutants and health risks during smoke events.
• Exercise raises air intake significantly, bringing more pollution into the lungs.
• Indoor exercise in clean air is still encouraged.

Reduce Indoor Air Pollution:

Check the Fact Sheet for details on indoor air filtration systems.

• Steer clear of indoor pollution sources like smoking, stove use, aerosols, cooking methods, candles, incense, and vacuuming.
• Lower indoor pollutant emissions during smoke events to reduce particle levels.

Use Room Air Cleaners:

Find a CARB-certified air cleaner suitable for your indoor space size, efficiently removing particles without ozone production.

• Plan ahead by getting an air cleaner before smoke emergencies.

Reduce Smoke Inside Vehicles:

• Keep vehicle windows and vents closed to reduce smoke intake.
• Use air conditioning in "recirculate" mode if possible.
• Consult the owner's manual to ensure the system is set to minimize outdoor smoke entry.

Avoid Smokey Periods:

Use AirNow to assess Air Quality levels by Zip Code.

• Monitor wildfire smoke levels throughout the day.
• Plan outdoor trips during times with lower smoke levels if possible.
