Creating a Calm, Cleaner-Air Home
Keep smoke out, filter the air, reduce indoor particle sources, and make one room easier for the household to live in. Lighting, sound, and routine come after the air plan is working.
A calm room is not useful if it becomes too hot or unsafe.
Keep windows and doors closed when smoke is worse outside, but follow heat warnings and local emergency directions. When the home cannot remain cool or the air cannot be kept cleaner, use an official cleaner-air or cooling location rather than remaining in unsafe conditions.
Build the cleaner-air room in this order
Choose the room where the household can spend the most time. A bedroom or family room with few exterior doors and windows is often easier to manage.
Choose the room
Prefer a room without a fireplace and with as few exterior openings as practical. Make sure it can remain comfortably cool.
Keep smoky air out
Close windows and doors. Set compatible HVAC or air-conditioning systems to recirculate and close outdoor-air intakes when appropriate.
Filter continuously
Run a correctly sized, non-ozone-producing portable air cleaner as often as possible, preferably at the highest tolerable setting.
Reduce indoor sources
Do not smoke, vape, burn candles or incense, spray aerosols, or create avoidable cooking particles in the room.
Keep it livable
Add water, medications, chargers, quiet activities, soft lighting, and a predictable schedule—without adding fragrances or mist.
Check and adjust
Inspect filters frequently, notice heat and symptoms, and air out the room only when outdoor air quality improves.
Cleaner-air room checklist
Estimate the minimum smoke CADR
EPA advises choosing a portable air cleaner with a tobacco-smoke Clean Air Delivery Rate of at least two-thirds of the room’s square footage for an eight-foot ceiling. This helper scales that estimate for higher ceilings.
Choose a unit rated for smoke and the room size, and avoid devices that intentionally generate ozone. For central HVAC, use MERV 13—or the highest rating your system can safely accommodate—after checking the manufacturer or an HVAC professional.
What to pause during smoke conditions
- Smoking or vaping indoors
- Candles, incense, fireplaces, and wood-burning appliances
- Aerosol cleaners, air fresheners, and spray products
- Heavy essential-oil diffusion or fragrance mists
- Frying, broiling, or other high-particle cooking when avoidable
- Vacuuming without a HEPA-filtered vacuum
Make the room feel less like an emergency
These are comfort tools, not air-cleaning tools. Use them only after filtration, temperature, official alerts, and medications are addressed.
Light
Use soft, indirect light where practical. Keep one brighter task area for reading, medication labels, and preparation.
Sound
Use familiar music, a quiet soundscape, or ordinary household sounds. Avoid masking emergency alerts.
Information rhythm
Keep urgent alerts enabled, but choose planned times for nonurgent news checks instead of leaving coverage running continuously.
Children
Use familiar snacks, a small activity bin, simple jobs, and a predictable explanation of what the household is doing to stay safer.
Sleep
Place the strongest filtration where higher-risk household members and children sleep, when feasible, and keep nighttime essentials within reach.
Connection
Choose one person outside the household for updates or support. A scheduled call can make a long indoor day feel less isolated.
When outdoor air improves
- Confirm conditions through AirNow and local guidance rather than relying only on smell or visibility.
- Air out the home during a cleaner period by opening windows or the outdoor-air intake, then use kitchen and bathroom exhaust fans as appropriate.
- Check portable and HVAC filters and replace them when dirty.
- Damp-dust or mop settled particles instead of stirring them back into the air.
- Continue monitoring symptoms and seek professional care for persistent or worsening breathing or cardiovascular symptoms.

The technical air guidance on this page is based on current federal wildfire-smoke recommendations. Local emergency instructions always take priority.
Keep the air visually and physically simple.
“When the household is indoors for days, I focus on fewer irritants, softer light, gentle sound, familiar meals, and predictable routines. The atmosphere can feel calmer without adding fragrance, smoke, mist, or another thing for the lungs to process.”
