Los Angeles Wildfire Smoke and Ash Cleanup

By Ishaq Khokhar. Updated October 3, 2026. 3 min read.

Short answer: After a Los Angeles wildfire, keep windows closed on smoky days, run HEPA air purifiers, and clean ash gently with water and a HEPA vacuum while wearing an N95 mask, gloves and eye protection. Do not use leaf blowers or dry sweep ash. Homes near burned areas may need professional cleaning, and many insurance policies cover smoke and ash damage even when the home did not burn.

In January 2025, the Palisades and Eaton fires destroyed thousands of homes and sent smoke and ash across the Los Angeles region. Even homes far from the flames were coated with ash. This guide covers Los Angeles wildfire ash cleanup and smoke damage for homeowners.

Ash from burned homes and cars can contain hazardous materials. Wear an N95 respirator, gloves, goggles and long sleeves, and keep children and pets away while cleaning.

Protecting your home during smoke

Keep windows and doors closed and set air conditioning to recirculate
Use portable HEPA air purifiers, especially in bedrooms
Use MERV 13 filters if your system can handle them
Follow air quality alerts from the South Coast Air Quality Management District

Cleaning ash safely

Do not use leaf blowers or dry sweep, which spread fine particles.
Gently mist ash with water, then scoop or wipe it up.
Use a HEPA vacuum indoors, not a regular vacuum.
Wash hard surfaces with mild soap and water.
Launder washable fabrics, and have delicate items professionally cleaned.
Replace air filters and have ducts checked if ash got inside.
Bag ash and dispose of it as local officials direct, and avoid washing ash into storm drains.
