The Science of Odor Removal: Why Candles and Sprays Don't Work

Whether it's the lingering smell of smoke after a fire, the musty odor of hidden mold, or the sharp stench of a sewage backup, severe odors can make a home uninhabitable. Masking them with store-bought sprays is a temporary band-aid.

Odor is Particulate Matter

Odors aren't just "smells"; they are microscopic physical particles floating in the air that eventually settle onto and penetrate porous surfaces like drywall, carpet, and upholstery. To permanently remove an odor, you must physically remove or chemically alter these particles.

Ozone Generators

Ozone (O3) is a highly reactive gas. When pumped into a sealed environment, the extra oxygen molecule attaches to the odor-causing particles, oxidizing and destroying them at the molecular level. It is incredibly effective for smoke and biohazard odors, but the area must be completely evacuated of people, pets, and plants during treatment.

Hydroxyl Generators

Hydroxyl generators use UV light to create hydroxyl radicals, which naturally occur in the earth's atmosphere to clean the air. Like ozone, they destroy odors at the molecular level, but they are safe to use in occupied spaces. This makes them ideal for ongoing restoration projects where the family is still living in the home.

Thermal Fogging

Smoke from a fire expands and penetrates deep into cracks and crevices. Thermal fogging heats a specialized deodorizing chemical, turning it into a fine mist with particles the exact same size as smoke particles. The fog follows the exact path the smoke took, neutralizing the odor at its source.
