Wildfire Smoke and Your Home: Cleanup After a Nearby Fire
Updated · Copperline editorial

During the fire
Keep windows and doors closed, set the AC to recirculate, and turn off swamp coolers — they pull outside air directly into the house.
After: the first cleanup
- Replace HVAC filters (you may need to more than once)
- HEPA-vacuum ash from floors and sills — don't sweep or use a shop vac without a HEPA filter
- Wear an N95 mask and gloves
- Wash hard surfaces with mild soap and water
When to call a professional
Visible soot on walls, ash inside ducts, discolored ceilings or odor that returns when the HVAC runs. See wildfire smoke damage cleanup.
Cleaning up after smoke exposure
Change HVAC filters, wipe hard surfaces with damp microfiber cloths, and wash fabrics. If odor persists or ash got inside, professional cleaning of ducts and surfaces may be needed, and homeowners insurance often covers wildfire smoke damage.
Protecting indoor air during smoke events
Close windows and doors, run the AC on recirculate, and use the highest-rated filter your system handles. A portable HEPA purifier in a bedroom creates a cleaner room to sleep in.

Yes, in recirculate mode with a high-efficiency filter, and keep windows and doors closed.
Can wildfire ash harm my home?
Ash can be caustic and stain surfaces. Avoid wiping it dry; use damp methods and wear a mask.
Can smoke damage be invisible?
Yes. Fine soot and odor can settle into HVAC ducts, insulation and fabrics without visible staining.
Is smoke odor cleanup covered by insurance?
Many homeowners policies cover smoke damage from wildfires; document odor and residue and check your policy.
