Smoke smell after a fire can make an ozone generator seem like a quick fix. It is not the first step—and it should not run in an occupied home.
The U.S. EPA says no federal agency has approved ozone generators for occupied spaces. At concentrations within public-health standards, ozone is generally not effective at removing many odor-causing chemicals. Higher concentrations can expose people and pets and may damage some materials.
Start with the smoke source and residue:
• Enter only after fire officials or the appropriate authority have cleared the space
• Assess how smoke and soot reached surfaces, contents, and the HVAC system
• Clean or remove affected source materials using methods matched to the residue
• Evaluate contents, filters, returns, and duct pathways before restarting equipment
• Use controlled ventilation and filtration when appropriate for the actual conditions
Professional ozone use, if considered at all in an unoccupied and controlled space, is condition-specific—not a DIY shortcut or a substitute for source cleaning.
