Smoke odor lives in porous materials — drywall, insulation, upholstery, clothing, ductwork — and survives surface cleaning. Air fresheners and scented candles only mask it; the smell comes back. Real deodorization removes the odor at the source: HEPA filtration, thermal fogging, ozone treatment, or hydroxyl generators, plus sealing of porous surfaces that absorbed odor.
It can, if the source wasn't fully treated. Odor that returns after cleaning usually means insulation, ductwork, or framing absorbed it and wasn't deodorized or sealed. A thorough job treats the source, not just the air.
No — ozone treatment requires the space to be vacated, including pets and plants. Your restoration company will tell you when it's safe to re-enter. Hydroxyl generators are the alternative that can run in occupied spaces.
HEPA air purifiers help with airborne particles during and after cleanup, but they don't remove odor embedded in materials. They're a supplement to deodorization, not a replacement for it.
Call a restoration pro now — the sooner cleanup starts, the less damage spreads.
