How to Use an Ozone Generator
Learn how to properly operate a MaxBlaster ozone generator for odor removal, vehicle treatments, mold remediation, and commercial applications. This guide includes step-by-step instructions, treatment run times, safety information, and technical references developed from over 20 years of real-world ozone applications.
Quick Start
These five steps summarize the basic process for using an ozone generator.
1. Inspect the Machine
Before starting a treatment, briefly run the machine to confirm it is operating normally. Air should be moving through the unit and you should hear a soft buzzing sound from the ozone generator plates. A noticeable ozone scent should also be present, and in low light you may see a faint purple glow between the plates. The machine should be kept reasonably clean and should not be operated if excessive dust or grime buildup is present inside the unit.
2. Prepare the Treatment Area
For best results, remove the odor source whenever possible and dry any moisture in the area. Open cabinets, drawers, closets, and other enclosed spaces so ozone can circulate throughout the treatment area and reach all surfaces. Ensure the treatment space does not have excess moisture or humidity, as this can reduce the effectiveness of ozone treatments. Use fans or a dehumidifier if necessary.
3. Place the Machine Properly
Position the machine around mid-height in the room, such as on a table or countertop, rather than directly on the floor. Ozone is slightly heavier than oxygen and tends to settle toward the lower areas of a room during a treatment. Elevating the machine helps ensure the intake side of the unit has access to a better supply of oxygen-rich air to feed the machine throughout the treatment.
4. Run the Treatment*
Treatment time will vary depending on the size of the space, the severity of the odor, and the model of machine being used. Refer to the Run Time Guide below for general recommendations and examples of typical treatment durations.
5. Air Out the Space
After the treatment is complete, allow ozone to naturally dissipate before re-entering the area. Opening windows or doors and using fans can help speed up the process and restore normal air conditions more quickly. Most ozone dissipates within the first couple of hours, although small amounts may linger for several hours depending on run time.
*Keep the Area Unoccupied
Ozone treatments should always be performed in unoccupied spaces. People and pets should remain outside the treatment area while the machine is operating. Breathing small amounts of ozone for a brief moment is generally not harmful for most people, but the higher concentrations used during odor removal treatments are not intended to be inhaled for extended periods. Always allow the space to air out properly before normal occupancy.
Treatment Preparation
Proper preparation greatly improves the effectiveness of ozone treatments. Because ozone works by contacting contaminated air and surfaces directly, preparing the space beforehand allows ozone to reach and neutralize odors more efficiently.
Remove the Odor Source
Ozone works best when the original odor source has been reduced or removed. For example, smoke residue, mold contamination, spoiled materials, and pet contamination should be cleaned or removed whenever possible before running a treatment. Ozone is extremely effective at destroying remaining odor molecules, but heavy contamination should always be addressed first.
Dry the Environment
Excess moisture can reduce the effectiveness of ozone treatments. If the space is damp or humid, allow surfaces to dry before running the machine. Fans, ventilation, or dehumidifiers can help improve conditions and allow ozone to work more efficiently.
Expose Enclosed Areas
Open cabinets, drawers, closets, and interior doors so ozone can circulate throughout the space. Ozone must physically reach surfaces in order to neutralize odors, so enclosed areas should be opened during treatment whenever possible.
Use Air Circulation When Needed
In larger rooms or buildings, fans can help distribute ozone more evenly throughout the treatment area. Gentle air movement helps ozone travel farther and improves the overall effectiveness of the treatment.
​
Divide Large Spaces When Needed
For very large spaces or severe odor situations, it may be helpful to divide the property into smaller treatment areas. Closing doors, isolating floors, or using temporary partitions such as plastic or drop cloths can reduce the treatment area size and allow ozone to reach higher concentrations more effectively. In larger properties, multiple machines may also be used in different sections at the same time.
Machine Placement
Proper placement of the ozone generator can significantly improve treatment effectiveness and help extend the life of the plate pack components.
​
Ensure Good Air Intake
The intake side of the machine should have access to clean, dry, oxygen-rich air throughout the treatment. Avoid placing the unit in tight corners, against walls, or in areas where airflow is restricted, as the machine needs a steady supply of fresh oxygen to operate efficiently.
Elevate the Machine When Possible
Placing the machine at countertop height or higher helps ensure the intake side of the unit continues pulling in a good supply of oxygen-rich air during the treatment. Ozone is slightly heavier than oxygen and tends to settle toward the lower areas of a room, so avoiding placement directly on the floor helps the intake draw from a better quality oxygen supply, especially during longer treatments.
​
Vehicles & Confined Spaces
For vehicles and confined spaces, the machine is typically placed outside the treatment area with a hose directing ozone into the cabin through a slightly open window or door. This allows the ozone generator to operate in fresh air while delivering ozone into the space being treated.
​
Large Space Treatments
In larger areas such as homes, basements, or commercial buildings, using fans can help move ozone throughout the space. For very large areas, multiple machines may be used to increase ozone concentration coverage.
Run Time Chart
Treatment time depends on the size of the space, the severity of the odor, and the amount of ozone being produced. The chart below provides general run time guidelines based on typical treatment situations using MaxBlaster ozone generators. These examples are intended as a starting point, and actual treatment times may vary depending on conditions within the space.​
Mild odors may be removed with shorter treatments, while severe contamination may require longer run times or multiple treatment cycles. Larger properties may also benefit from dividing the space into smaller sections or using multiple machines so ozone can reach higher concentrations.
Air Out Process
After the treatment is complete, ozone must be allowed to dissipate before the space is occupied normally. Ozone naturally breaks down and returns to oxygen over time, but airing out the treatment area will help restore normal air conditions more quickly.
​
Allow Ozone to Dissipate
Most ozone will naturally break down within the first couple of hours after a treatment ends. In enclosed spaces where windows and doors remain closed, a small amount may linger longer before fully returning to normal air conditions.
Vehicles
For vehicle treatments, opening the doors and windows usually clears the interior quickly. Many operators simply air out the vehicle for several minutes or drive the vehicle with the windows down to restore fresh air conditions.
​
Typical Air Out Time
In most situations, the majority of ozone will dissipate within about two hours. Any remaining trace amounts will continue breaking down naturally and are typically gone within 12–24 hours.​
Maintenance & Troubleshooting
MaxBlaster ozone generators are designed for long service life when kept clean and operated in proper conditions. Basic care and occasional inspection will help maintain strong ozone output and reliable operation over time.
​
Keep the Machine Clean
The most important step in maintaining your MaxBlaster is keeping the inside of the machine clean, dry, and free of dust or debris. Always operate the unit where it can draw clean, dry air and avoid running it directly on the floor. Because ozone naturally settles lower in the room during treatment, positioning the machine higher in the space allows the intake to access a better supply of oxygen-rich air.
Confirm Normal Operation
When operating correctly, the machine should move air through the unit, produce a noticeable ozone scent, and emit a soft buzzing sound from the plate pack. In low light conditions you may also see a consistent purple glow between the plates, which indicates the corona discharge is functioning normally.
​
Plate Pack Replacement
The generator plate pack is the primary component responsible for ozone production and may require replacement after extended use. Replacement plate packs can be purchased through our shop and installed by the operator, or the machine can be sent to our service department for full inspection and service.​
​
Service & Support
If the machine stops producing ozone or appears to be operating abnormally, discontinue use and inspect the unit. Additional troubleshooting guides and the MaxBlaster service request form are available on our Service Department page.
Safety Guidelines
Ozone generators produce high concentrations of ozone intended for odor removal and oxidation treatments. When used properly, these machines are safe and effective tools, but basic precautions should always be followed during operation.
​
Operate in Unoccupied Spaces
Ozone treatments should always be performed in unoccupied areas. People and pets should remain outside the treatment space while the machine is running.
Avoid Over Exposure
Ozone has a strong, noticeable scent. While brief exposure to small amounts is generally not harmful for most people, high concentrations used for treatments are not intended to be inhaled for extended periods.
​
If You Are Exposed
If you are exposed to high levels of ozone, the most common symptoms are mild irritation of the lungs, throat, or eyes. If this occurs, simply leave the treatment area and breathe fresh air. In most cases, any discomfort will pass quickly once you return to normal air conditions.
​
Allow Proper Air Out Time
After a treatment is complete, allow the space to air out and return to normal air conditions before occupying the area again.
