Create a Clean Room During a Wildfire SEPA Avoid creating smoke and other particles indoors from cooking, smoking or burning candles. Filter the air with a portable air cleaner that does not produce ozone. Close windows and doors to prevent smoke from entering the room. Stay cool. Run fans or set your air conditioner to recirculate. If possible, use a MERV13-rated filter. Close blinds and curtains. Learn more at epa.gov/iaq ------- |
