Smoke-Day Plan Builder
Create a conservative smoke-day indoor air plan for one room or household.
Smoke days are easier when the room, filters, cooling path, and indoor activity changes are decided before the smoke arrives.
This tool does not replace local advisories. It helps organize household actions around filtration and source reduction.

Result
Adjust the fields to calculate a result.
How to use this tool
- Choose the outdoor condition and how leaky the home feels.
- Enter the number of usable purifiers and whether cooling depends on outdoor air.
- Read the result as a checklist for the next few hours, not a health guarantee.
What the result means
The result ranks the plan as basic, better, or fragile based on closure, filtration, cooling, and indoor particle sources.
When heat, symptoms, medical vulnerability, evacuation orders, or official guidance conflict with the plan, follow the official guidance.
Assumptions and limitations
The tool assumes wildfire or outdoor particle smoke, not an active indoor fire or carbon monoxide event.
It does not estimate personal exposure or certify that indoor air is safe.
