Wildfire-smoke Clean Air Room door sign

Ready-to-use prompt

Create a Wildfire-smoke Clean Air Room door sign for homes, shared apartments, elder care, building managers, and community centers. Make it look like a door seal strip, purifier placement diagram, filter-change sticky note, and AirNow map card. Include close windows and doors when smoke is visible, smelled, or air quality is poor, switch HVAC or fresh-air systems to recirculate or follow device instructions to reduce intake, place a portable air cleaner or compliant DIY filter in the room used most, prepare MERV 13 or compatible high-efficiency filters, check dirty filters, reduce door traffic and indoor combustion sources, and follow local air-quality and evacuation updates. Do not show disaster panic, diagnose symptoms, or replace local emergency and public-health guidance.
