What Is an Ozone Generator Used for in Restoration?
Last updated October 25, 2026
The short answer
How Ozone Generators Work
Ozone generators release ozone, a reactive form of oxygen, into the air. The gas penetrates fabrics, drywall, wood, and other porous surfaces, breaking down odor-causing molecules. This makes it useful for tackling stubborn smells that regular cleaning cannot remove.
During treatment, the room or building must be empty of people, pets, and plants. Ozone in high concentrations can be harmful to breathe. The pros set up the generator, run it for a set time, and then air out the space before anyone returns.
Common Uses in Water Damage Restoration
After water damage, musty odors from dampness and mildew are common. An ozone generator can help neutralize those smells, especially in carpets, upholstery, and wall cavities. It also helps with odors from floodwater, which may include sewage or chemical residue.
Ozone is not a replacement for drying and cleaning. It works alongside dehumidifiers, air movers, and thorough cleaning. The pros use ozone as a finishing step to eliminate lingering odors after the space is dry and sanitized.
- Neutralizes smoke and pet odors
- Reduces musty smells from damp materials
- Helps with sewage or floodwater odors
- Penetrates porous surfaces like wood and fabric
- Used after drying and cleaning, not instead of them
- Requires the area to be vacated during treatment
Safety and Precautions
Ozone is a strong oxidizer, so safety matters. You should never be in the room while the generator runs. After treatment, the space needs to be aired out until the ozone smell fades. If you feel unwell, see a doctor.
The pros follow safety guidelines for ozone levels and exposure times. They also check that the area is sealed to keep the gas contained. You should ask the pros about their safety procedures before they start.
When Ozone Is Not Enough
Ozone does not remove physical mold growth or clean surfaces. It only neutralizes odors. If mold is present, you need a mold professional to remove it safely. For electronics, ozone can damage components, so it is not used on them.
For items like artwork or antiques, ozone may harm finishes or pigments. Those require specialized care, not ozone treatment. In such cases, consult a professional who handles those materials.
Cost and Practical Considerations
The cost of ozone treatment depends on the size of the affected area, the severity of the odors, and how long the generator needs to run. You might pay a few hundred dollars for a small room, but it can be more for a whole house. The exact price depends on your situation.
If you live in Roswell, you can ask local water damage pros about their ozone services. They can explain the process and give you an idea of what to expect. Always check your insurance policy to see if odor removal is covered. Policies vary, and your insurer decides what is covered.

Is ozone treatment safe for my pets?
No, pets should not be present during ozone treatment. Ozone can irritate their lungs and eyes. The area must be empty of all animals until the treatment is done and the space is fully aired out. Ask the pros how long to wait before bringing pets back.
Can ozone remove mold smell permanently?
Ozone can neutralize the odor, but it does not kill mold or remove it. If mold is present, you need a mold professional to clean and remove it first. Otherwise, the mold will keep growing and the smell may return.
How long does ozone treatment take?
Treatment time varies based on the size of the area and the strength of the odors. It can take a few hours to a full day. The pros will set the generator and monitor the process. Afterward, you need to air out the space for several hours.
