An ozone generator is a powerful oxidizer that produces an adequate amount of ozone gas to neutralize odors by reacting and breaking down harmful substances. Its three oxygen atoms (O3) make it unstable and highly reactive, and its oxidizing property will kill mold and bacteria to purify the air and water. These generators are quite useful in various situations, including mold and mildew control, odor removal, surface disinfection, and food preservation. They effectively remove stubborn smells (smoke, pets, or dampness) and fight germs in the surface/air to maintain a clean and healthier area.
Whether in a home, office, or car, the use of the right ozone generators will help keep spaces clean. Don’t get overwhelmed by the numerous options on the market. These are three main factors that have to be considered to make your selection the most suitable one according to your requirements and preferences.
- Ozone Output – It lets you know the amount of ozone gas produced by the generator, and measured in terms of milligrams per hour (mg/h). Different models offer different output ranges, in which you have to select the generator whose output suits better for your coverage area. For instance, a small unit with a 500 mg/h output range is enough for most households. A medium generator with a 10000 mg/h output range is ideal for mid-sized rooms and offices. Finally, a larger unit with up to 20000 mg/h (or more) output range is required for commercial spaces.
- Coverage Area – For effective results, it’s always better to consider the area to be covered by the generator. The capacity to purify the air within the preferred area varies from one model to another. So, choose the generator as per the area to be covered. For instance, a smaller model is ideal for covering an area of around 500 square feet, a mid-range model will efficiently cover an area of up to 1000 square feet (smaller homes or apartments), and an industrial-grade model is a must for a coverage area of up to 5000 square feet.
- Timer – Exposure to excessive ozone isn’t good for human health. This makes most manufacturers come up with an exceptional timer feature. It is a customizable timer option that lets the user set a specific time duration (from 30 minutes to 2 hours) for ozone emission to clean the area. Thus, it offers flexible, convenient, safe, and controlled usage.

Factors To Consider When Choosing An Ozone Generator
An ozone generator produces and releases ozone gas into the air to remove unpleasant odors, kill microorganisms, and sterilize the indoor air. It can be used in both household and commercial places, but choosing the right option will make all the difference. So, take a look at the below-mentioned key factors that help you to choose the best option for your specific needs.
1. Ozone Output
We know that ozone generators produce a certain amount of ozone gas to perform their cleaning or other tasks. Here the particular amount of O3 gas is termed as ozone output, and it is measured in milligrams per hour (mg/h). Does it really matter in the selection procedure? Well, it does. The main reason is that an ozone generator with higher ozone output for a small task will raise the safety issue, whereas, a generator with less output for a heavy cleaning task isn’t enough to perform the task properly. So, it’s better to choose the model with appropriate output that perfectly suits your requirements without harming humans or the environment.
- For most household tasks, a generator with an output ranging from 100 mg/h to 10,000 mg/h is required.
- For industrial purposes, a generator with an output of 20,000 mg/h (or higher) is quite essential.
Always pick the generator based on your intended applications for the best results. For example, a lower output unit performs well for smaller spaces or mild odor removal, whereas larger spaces or heavier tasks (like mold remediation or water purification) require higher output models.
2. Timer Settings
Prolonged exposure, especially to high-concentration of ozone gas is not at all safe for human health. Then you may doubt how to operate and check the task performed by the generator. This makes the manufacturers introduce this timer setting feature. This is a customizable timer setting that lets you control the operational time from 10 minutes to 3 hours of the generator as per your requirement. So, choose the model having adjustable timers, and an automatic shut-off feature that prevents overexposure and saves a lot of energy without causing any harm to the surroundings. However, for continuous or extensive usage, select a unit with programable settings, which allow for daily or customized schedules.
3. Noise Level
Similar to other types of generators, these ozone generators produce a certain level of noise. Therefore, it is vital to check the noise level of the unit, especially if you want to use it for extended periods or in occupied spaces. The standard noise level of these generators will range from 30 – 60 decibels. Prefer quieter models for most home or office use, whereas, go with noisier industrial models for short-term operation (or) use in unoccupied areas. To get a clear idea of their real-time operating noise level, then simply check the product specifications or read its reviews.
4. Safety Features
Ozone is a powerful oxidant that has to be used properly. If not, its exposure will definitely pose various health problems. So, modern generators have safety features that include automatic shut-off, warning lights, or child locks. Also, select a model with ozone concentration monitors to measure and regulate the output levels and avoid exceeding its safer limits. Furthermore, you need to consider the generators that must have safety standard certification (like UL or CE) as an added layer to ensure your device’s safety.
5. Portability
The weight and the size of the generator determine its portability, which is essential to consider for users who want to move the generator from one place to another. For best results, prefer a compact and lighter model with built-in handles to ease their transportation. For example, smaller units weighing from 4 – 7 pounds will aid in the ease of using the generator around, whereas larger industrial models weighing over 20 pounds will be heavier and can be used only in one place. So, it is always better to consider your intended use to find a perfect balance between portability, and performance while selecting the model.
6. Additional Features
Having extra features in any product will enhance its usability, performance, and versatility. Take a look at some of the additional features and choose the required features in your generator for enhanced performance.
- Integrated Air Filters will improvise the overall air quality by efficiently removing the dust and allergens before starting the actual ozone treatment.
- Multiple Operating Modes – A wide variety of operating modes, such as UV sterilization or ionization in various advanced models. This is quite useful for a wide range of applications.
- Maintenance – Even though the ozone generators don’t need a lot of maintenance, they just simply require periodic cleaning of the ozone plates inside the unit. Thus, it enhances optimal performance and extended lifespan.
- Controls – Focusing on the various control features of the generator, such as the on/off switch, remote controls, digital displays, and app compatibility will provide convenient operation, especially for large or multi-purpose devices.
FAQs:
An ozone generator will create and release ozone gas to sanitize and clean the air and objects around it. While air purifier traps pollutants, allergens and other substances with the help of a filter beforehand returning the air to the room.
We can easily get rid of cigarette smoke by using an ozone generator. Here the ozone will attack smoke molecules at its source. Thus, the generator is a perfect option for spaces that are exposed to fire damage, cigarette smoke, and cooking odors.
Based on the amount of ozone (mg) produced by the generator, ozone gas stays in the air from 30 minutes to 4 hours. We suggest you to re-enter the room safely after 1 – 2 hours of treatment with ozone gas.
Due to its high concentrations of ozone, the generator can easily kill mold spores permanently. The generator is considered commonplace for mold remediation contractors. While surface mold clean-up is required for remediation of mold thoroughly.
One has to know how long does their ozone generator will last before buying and using it. However, the average lifespan of this generator will be around 3 years. The machine’s lifetime depends mostly on the frequency of its usage and regular cleaning of its plates.

An ozone generator is effective in removing odors, which makes it ideal for high-traffic areas like bathrooms or kitchens. Some powerful generators can clean the air and eliminate odors from spaces as large as 3750 square feet.
It completely depends on the size of the space directly. You have to run it for about 3 – 10 hours for a room, and thereby a minimum of 25 – 30 hours for a house, which is sufficient to destroy almost all pollutants. It is a must to wait for 30 minutes to 4 hours for ozone atoms to revert back into oxygen and thereby to have a safe entry into the room/space after the machine has stopped working.
Since, an ozone generator kills micro-organisms within a limited/restricted space, they are used widely in hospitals to sanitize a room every time a patient leaves the room or space. They are perfect for sterilizing rooms, even for surgery.
High-concentrated ozone has a sharp smell, and mostly it is described as chlorine-like. As most people even feel it after and before the storm.
An ozone generator is extremely hazardous if not used correctly, even these are banned in California. So, it is a must to follow the proper safety precautions while using them. Also, leave the home when it is running and give it some time to air out after it’s running.
