The short answer
How Ozone Treatment Works
Ozone treatment generates ozone gas, a reactive form of oxygen, and releases it into the affected space. The gas oxidizes odor-causing compounds and microbial cells, which helps remove lingering smells from wet carpets, drywall, and upholstery. Pros often use this method after water extraction and structural drying are complete.
Because ozone is a gas, it can reach into cracks and porous materials where surface cleaners cannot. This makes it useful for tackling deep-set musty odors. However, ozone treatment does not remove water or repair damaged materials. It works as a finishing step in a full water damage response.
When Ozone Treatment Makes Sense
You might consider ozone treatment if your home has a persistent musty odor after a leak or flood, even after drying and cleaning. It is especially helpful for porous items like furniture, clothing, and books that absorb smells. Pros can set up ozone generators in the affected area for a period of time.
Ozone treatment is not a substitute for removing wet materials or drying the structure. If you have standing water, saturated drywall, or soaked insulation, address those first. The pros typically use ozone after the space is dry and clean, to handle the odor layer that remains.
- Neutralizes smoke and musty odors in porous materials
- Reaches behind walls and under flooring as a gas
- Kills mold spores and bacteria on surfaces
- Useful after flooding, burst pipes, or sewage backups
- Not a replacement for water extraction or drying
- Requires the area to be sealed during treatment
Safety Considerations for Homeowners
Ozone gas is harmful to breathe in high concentrations. Pros set up the treatment while the home is unoccupied and ventilate the space before you re-enter. You should not be in the room during the process, and pets should be kept away until the pros say it is safe.
If you have asthma, allergies, or other respiratory conditions, mention that to the pros before treatment. They can adjust the process or suggest alternatives. After the treatment, the ozone breaks down into oxygen quickly, but proper airing out is still necessary.
- Leave the home during ozone treatment
- Keep pets away until the area is ventilated
- Tell the pros about any respiratory conditions
- Open windows after treatment to air out the space
- Follow the pros' instructions for when it is safe to return
Ozone Treatment vs. Other Odor Control
Other odor control methods include thermal fogging, which uses a heated fog to carry deodorizers, and hydroxyl generators, which use UV light to create cleaning molecules. Ozone treatment is often chosen for its ability to penetrate deeply and neutralize a wide range of odors.
Each method has its strengths. Thermal fogging may be faster for surface odors, while ozone is more thorough for porous materials. The pros can recommend the right approach based on the source of the odor and the materials affected. In some cases, they combine methods for a better result.
What to Expect During Ozone Treatment
The pros will assess the affected area, seal it off, and place one or more ozone generators. The treatment time depends on the size of the space, the severity of the odor, and the materials involved. You may be asked to leave the home for several hours or overnight.
After treatment, the pros ventilate the space and check the results. If odors persist, they may repeat the process or use additional methods. Ozone treatment is not a one-time miracle; it requires proper preparation and follow-up to be effective.

Is ozone treatment safe for pets?
Ozone gas can be harmful to pets, so they should not be in the home during treatment. Keep them in a safe, ventilated area away from the treated space. The pros will let you know when it is safe for pets to return, usually after the area has been aired out.
How long does ozone treatment take?
Treatment time varies based on the size of the affected area and the level of odor. It can take a few hours for a small room, or longer for larger spaces or severe odors. The pros will give you an estimated time before they start, and you should plan to be away during that period.
Can ozone treatment remove mold?
Ozone can kill mold spores on surfaces, but it does not remove mold growth or the underlying moisture problem. For mold issues, you need to address the water source, remove contaminated materials, and clean the area properly. Ozone treatment can be a supplemental step after mold remediation.
