Wildfire Smoke Clean-Room Planner
Build a practical cleaner-air room for wildfire smoke or poor air-quality days. Enter your room size, air-cleaner options, HVAC setup, and household needs to get a prioritized clean-room plan.
This tool is for general preparedness and exposure-reduction planning only. It does not replace official reports, evacuation orders, public-health instructions, or medical advice.
What a clean room is
A clean room is a practical indoor room where smoke entry is reduced and filtered air is concentrated.
How room size and CADR affect the plan
Use smoke/tobacco CADR at least two-thirds of room area. Taller ceilings may require larger sizing.
How to reduce smoke entry
Keep windows and doors closed, reduce door openings, and avoid indoor particle generation.
When masks/respirators may help
If you must go outside, reduce exertion/time and use a well-fitting NIOSH-approved respirator when possible.
