Professional Odor Control for Restoration & Remediation
When a restoration project involves persistent smoke, fire, water, mold or other difficult odors, conventional cleaning alone may not be enough. Professional odor control equipment can help restoration teams address odor challenges after the source has been removed and affected areas have been cleaned.
UnoClean offers International Ozone equipment designed for professional restoration and deodorization applications. The selection includes ozone generators for intensive treatment in unoccupied spaces and hydroxyl generators for longer-duration odor treatment where continuous operation is appropriate.
International Ozone equipment ranges from compact portable units for smaller spaces to higher-output machines designed for larger restoration projects. With multiple output levels, airflow capacities and coverage ranges available, restoration professionals can select equipment appropriate for the size and requirements of each job.
Choose the Right Odor Control Technology
Ozone Generators
Ozone generators produce ozone for intensive odor treatment. International Ozone Total Zone models range from compact 300 mg/hr and 600 mg/hr UV units to higher-output systems producing up to 12,000 mg/hr. These machines are particularly suited to aggressive odor treatment in unoccupied spaces.
Hydroxyl Generators
Hydroxyl generators provide an alternative approach to odor treatment using hydroxyl technology. Titan models are designed for ongoing deodorization and air treatment applications, including situations where longer-duration treatment is desirable.
Ozone vs. Hydroxyl: The Basic Difference
Ozone generators are generally selected when intensive odor treatment is required and the treated area can be left unoccupied during treatment. Hydroxyl generators are designed for a different type of application, providing ongoing deodorization and air treatment without relying on high concentrations of ozone.
Choosing between the two depends on the environment, odor problem, occupancy, treatment duration and restoration protocol being followed.

When to Use Ozone Generators
Fire & Smoke Damage
Smoke odor can remain after visible soot and residues have been removed. Ozone treatment can be incorporated into professional restoration procedures for difficult smoke and fire-related odors in appropriate unoccupied environments.
Water Damage & Flood Restoration
Water losses can leave behind persistent musty, mildew and other unwanted odors. Ozone equipment can be used as part of a broader restoration process after water extraction and appropriate cleaning have been completed.
Mold Remediation
Restoration teams may encounter persistent odors associated with mold and moisture. Odor treatment equipment can help address residual odors after the underlying source has been properly remediated.
Trauma & Biohazard Cleanup
Professional cleanup environments can present demanding odor-control challenges. High-output ozone equipment may be incorporated into established restoration and deodorization procedures for appropriate unoccupied spaces.
When to Choose a Hydroxyl Generator
Hydroxyl technology can be useful when odor treatment needs to continue for longer periods or when a restoration project cannot be treated using an ozone generator because the space needs to remain occupied.
Occupied Environments
The current UnoClean page positions hydroxyl generators for applications where people may remain in the building, including environments such as hospitals, nursing homes and hotels.
Long-Duration Treatment
Hydroxyl equipment can be considered when odor treatment needs to continue over an extended restoration, remodeling or cleanup project rather than relying on a short intensive treatment period.
Ongoing Deodorization
Hydroxyl generators can be used for ongoing treatment of smoke, cooking, pet and other persistent odors where continuous deodorization is desired.
Why Restoration Professionals May Use Both Technologies
Ozone and hydroxyl generators are not necessarily competing technologies. They can serve different roles within a restoration operation. Ozone generators are intended for intensive treatment in unoccupied spaces, while hydroxyl equipment can provide longer-duration deodorization in environments where continuous treatment is appropriate.
Choosing the Right Ozone Generator
Selecting an ozone generator should start with the size and characteristics of the treatment area, followed by the desired ozone output, airflow and portability requirements.
1. Determine the Treatment Area
Start with the approximate square footage of the space requiring treatment. International Ozone models range from units listed for 1,500 square feet to high-output systems listed for up to 48,000 square feet.
2. Consider Ozone Output
Ozone output is expressed in milligrams per hour. The International Ozone lineup ranges from 300 mg/hr through 12,000 mg/hr, giving restoration professionals several output levels to choose from.
3. Look at Airflow
CFM indicates the airflow associated with the equipment. The smaller Total Zone units provide 100 CFM, while the larger TZ-4 and TZ-8 models provide 400 CFM.
4. Evaluate Portability
For restoration contractors moving equipment between homes, vehicles and commercial properties, machine size and weight can be important. The compact TZUV and TZ-1 models are easier to transport than the larger TZ-4 and TZ-8 systems.
5. Consider the Environment
The treatment environment is critical when choosing between ozone and hydroxyl technology. Ozone generators are generally used in unoccupied areas, while hydroxyl generators may be selected for longer-duration treatment where occupancy needs to be considered.

Important Ozone Safety Considerations
Ozone is a powerful oxidizing agent and can be harmful at elevated concentrations. Ozone generators should therefore be used only according to the manufacturer's operating instructions and applicable safety procedures.
The current UnoClean page specifically positions ozone generators for unoccupied areas during treatment. Occupants, pets and other individuals should not be exposed to ozone during an ozone treatment. Restoration professionals should follow appropriate entry, ventilation and re-occupancy procedures for each application.
Use the Manufacturer's Operating Guidelines
International Ozone's Total Zone operating documentation includes warnings, precautions, general use guidelines, maintenance information and troubleshooting instructions. Always review the operating documentation for the specific model before putting the equipment into service.
