What Is Ozone Treatment Used for in Fire Restoration?
Last updated October 25, 2026
The short answer
How Ozone Treatment Works
Ozone generators release ozone gas, which is a molecule containing three oxygen atoms. This gas is highly reactive and seeks out other molecules to bond with and oxidize. In fire restoration, the ozone targets the volatile organic compounds that cause smoky smells.
As these odor molecules are oxidized, their chemical structure changes. This neutralizes the odor rather than merely masking it with a fragrance. The treatment works on odors trapped in the air and those absorbed into fabrics, furniture, and other porous items in your home.
- Targets volatile organic compounds (VOCs) from smoke
- Oxidizes odor molecules to change their structure
- Works on airborne and absorbed odors
- Is a gas that penetrates porous materials
- Neutralizes odor instead of covering it up
- Requires specialized equipment to generate
What Ozone Treatment Can Address
This method is effective for removing the stubborn, lingering smell of smoke that remains after surface cleaning. It can treat odors embedded in upholstery, drapery, carpets, and even within the structure of walls and cabinetry. The gas can reach areas that are difficult to clean manually.
Ozone is particularly useful for neutralizing odors from protein fires, like burnt food, and synthetic material fires, which create harsh chemical smells. It does not remove soot or ash, so physical cleaning must happen first for the treatment to be fully effective.
Safety and Preparation Are Crucial
Ozone is a lung irritant and can be harmful to people, pets, and plants. The area being treated must be completely sealed and vacant. The pros will set up containment and use air monitoring equipment to ensure safety throughout the process.
You will need to remove all living beings from the home during treatment. The pros will also advise you on securing or removing sensitive items, as high ozone concentrations can damage certain materials like rubber, artwork, and some electronics.
The Role in the Full Restoration Process
Ozone treatment is one step in a multi-phase approach to fire damage restoration. It typically occurs after all charred debris is removed and surfaces are cleaned of soot. It addresses the odor problem that cleaning alone cannot solve.
After the ozone treatment is complete and the gas has safely dissipated, the area must be ventilated. The pros will then often perform a final air scrubbing or use other deodorizing methods to ensure the air quality in your home is restored.
- Occurs after debris removal and soot cleaning
- Is not a substitute for physical cleaning
- Requires proper ventilation after completion
- Often followed by air scrubbing or hydroxyl treatment
- Is part of a comprehensive deodorization plan
- Helps restore indoor air quality
When to Consider This Treatment
You may need ozone treatment if smoky odors persist after professional cleaning and ventilating your home. It is a common solution for moderate to severe fire damage where odors have deeply penetrated building materials and contents.
A qualified restoration professional can assess your home to determine if ozone is the right approach. They consider the fire's source, the extent of smoke penetration, and the types of materials affected before recommending any deodorization strategy.

Is ozone treatment safe for all my belongings?
No, high ozone levels can degrade certain materials like rubber, silk, leather, some plastics, and artwork. The pros will guide you on which items to remove from the treatment area to prevent potential damage during the process.
How long does an ozone treatment take?
The treatment duration varies based on the severity of the odor and the size of the space. It can range from several hours to a few days. The area must remain sealed and unoccupied for the entire treatment period.
Can ozone treatment remove mold or bacteria?
While ozone can kill some microbial organisms, it is not a reliable or complete method for mold remediation. For mold issues, you should consult a mold professional who follows established guidelines for containment and removal.
