Prepare before smoke arrives
Health Canada advises homeowners to prepare by keeping ventilation-system and portable-air-cleaner filters current, considering an appropriately sized portable air cleaner, and keeping windows and doors in good condition. Preparation is easier before local conditions are poor.
When outdoor air quality is poor
Health Canada’s guidance for sheltering at home includes reducing indoor sources of pollution, limiting the entry of outdoor air where appropriate, and using suitable filtration. Avoid creating extra particles indoors with activities such as smoking, burning candles or incense, or unnecessary vacuuming without an appropriate filter.
Use filtration thoughtfully
Portable air cleaners can help filter fine particles from wildfire smoke when they are sized for the room and maintained as directed. For a central system, filtration and operating settings should be considered in the context of the system and the home. Change filters according to the manufacturer’s guidance and the conditions you are experiencing.
