How Does Ozone Treatment Work for Odor Removal?

Ozone is a molecule composed of three oxygen atoms. It is an unstable gas that readily gives up one of its atoms. This extra oxygen atom aggressively seeks to bind with other molecules. When it encounters odor-causing compounds, a chemical reaction occurs that permanently alters their structure, eliminating the source of the smell. This oxidation process effectively destroys the molecules responsible for unpleasant smells.

These odors often come from bacteria, mold, smoke, or decaying organic matter. By breaking these compounds apart, ozone eliminates the odor at its source. The result is air that smells neutral and clean, not perfumed. The treatment neutralizes rather than masks the odor.

Ozone treatment is particularly effective on stubborn, persistent odors that linger after water damage. It tackles the smell of mildew and mold that can grow in damp drywall or under flooring. It also neutralizes odors from sewage backups, which contain harmful bacteria and gases. Smoke odors from a small fire can also be remediated with this method.

For general mustiness in a basement or crawl space, ozone can be a solution. However, it is a final step, not a first one. The underlying moisture problem must be solved first. Ozone treats the symptom, but removing wet materials stops the odor from returning.

• Mold and mildew smells in walls and floors
• Persistent mustiness in carpets and upholstery
• Odors from sewage or contaminated water
• Smoke smells from household fires
• Pet urine odors that have soaked in
• Cooking smells that have permeated cabinets

Consider ozone treatment after the water source is fixed and all wet materials are removed. It is for odors that remain after thorough cleaning and drying. If you have tried airing out the home and the smell persists, ozone may be the next step. A water damage inspection can determine if the odor is trapped inside walls or subfloors.

This is not a do-it-yourself project due to the significant health risks. You need a professional assessment. The pros can tell you if ozone is the right approach for your specific odor problem. They can also recommend other necessary services, like wet insulation removal or structural drying.
