VERT / GREEN
Know the highest filter quality the system can handle and plan a certified room-sized air cleaner if needed.
Wildfire smoke: filtration and cleaner indoor air
Prepare envelope, filtration, recirculation, cooling and spare filters before smoke events.
JAUNE / YELLOW
Closing the home against smoke can increase heat, CO2 or combustion issues; filtration, temperature and ventilation must be managed together.
ROUGE / RED
Unable to maintain cleaner air and safe temperature, CO alarm or unstable combustion appliance: move to an appropriate space and correct the system.
Interactive triage
Helps choose the next step; it does not replace design, permits or professional diagnosis.
