Are ozone generators safe? Unfortunately, no. The EPA has denounced these devices and cites several scientific studies showing they can be harmful to health and ineffective at removing airborne contaminants. That is why no federal agencies have approved ozone generators for use in occupied spaces.
How does ozone work?
Ozone generators work by: 1 Silent corona discharge: These machines use electric discharge to produce ozone by splitting the normal oxygen molecules in the air into single atoms. These atoms then attach to other O 2 molecules in the air to form ozone (O 3 ). 2 Ultraviolet radiation: This process of ozone generation is similar to how the sun’s ultraviolet radiation splits O 2 to form individual oxygen atoms. According to InterNACHI, this process is considered to be less efficient than corona discharge.
How much ozone can an indoor device produce?
For context, the US Food & Drug Administration (FDA) requires that indoor medical devices can only produce a maximum of 50 ppb (parts per billion) of ozone. The National Institute of Occupational Safety and Health (NIOSH) recommends that indoor ozone levels should not be greater than 100 ppb.

Why is ozone important?
Health experts warn that it is important to control conditions to ensure that no person or pet becomes exposed to high levels of ozone.
How to control air pollution?
Source control is most effective and easy to implement: 1 Remove products and materials, which cause indoor air pollution, or replace with an alternative non-polluting product. 2 If no alternative product is available, store the polluting source elsewhere, for example paint thinners are best stored in a detached garage or shed. 3 If you can not remove the source, try to reduce its strength. For example, sometimes formaldehyde-emitting materials such as MDF can be sealed to reduce the rate of emission. 4 Do not allow people to smoke in your home. 5 Routinely clean wet or moist surfaces to prevent mould and bacterial growth. 6 Fix plumbing leaks and other water problems as soon as possible and dry all items completely. 7 Separate damp areas from living areas and keep bathroom doors closed to reduce humidity in your home. For example vent clothes dryers to outside or locate the washing machine in a separate laundry.

Ozone also masks the odour of some pollutants by impairing a person's sense of smell. Further, ozone is not effective for killing bacteria or mould in materials such as air conditioning duct lining and ceiling tiles.
Is ozone a toxic gas?
However, ozone is a toxic gas with very different properties to oxygen. Whether it is a pure form or mixed with other chemicals, ozone can be harmful to health.
Do filters need maintenance?
To be effective they require proper sizing, installation and use (according to the manufacturers directions), and maintenance, so they are more suitable for use in workplaces rather than homes. Maintenance costs, such as replacement of filters, can be significant.
Is ozone generator safe?
However ozone is associated with adverse health effects. Available scientific evidence shows that ozone concentrations that are safe to breathe are unlikely to be effective in controlling indoor air pollution.
What are the health effects of ozone?
This may include decreased lung function, throat irritation, severe asthma symptoms, cough, chest pain, shortness of breath, irritation of lung tissue, and the higher sensitivity to respiratory infection.
Why can't I get rid of ozone in my upholstery?
The reason you can’t get rid of this now is because the ozone has gotten inside of all of your upholstery. It may take a few days with the windows down but it will go away. The main thing to know is this, when you smell the ozone and you do not have to machines running is because the ozone has done its job and permeated every surface. It is inside of everything, killing mold, germs, bacteria, viruses and more. It is true that you should not breathe high quantities of ozone. But then again, when our machines are running, you can smell it, you know it’s there, so stay away from it. Just know this, it works 100% of the time I’m like some cheap fan in front of a pile of charcoal
What happens when you mix ozone with chemicals?
For example, when ozone was mixed with chemicals from new carpet in a laboratory setting, the ozone reduced many of the chemicals but created a variety of dangerous organic chemicals in the air. While the target chemicals were reduced, the dangerous byproducts rendered the process moved. 3.
Which is better, ozone or hEPA?
Ozone is amazing for air purification, though it does have some caveats and must be used carefully. To assert that HEPA filters are better is totally asinine, as these filters only remove dust from the air, while recycling microscopic mold, virus and other pollutants back into the air. Ozone and HEPA do different things and to compare them apples to apples is just plain STUPID.
Does ozone generator have an ionizer?
To combat this, some ozone generators include an ionizer which disperses negatively charged ions into the air. In recent analysis’s, this process was found to be less competent in the removal of air-borne molecules of dust, smoke, pollen, and mold spores than HEPA filters and electrostatic precipitators. 4.
Do ozone generators remove particles?
Ozone Generators Do Not Remove Particulates. A third factor to consider when looking at ozone generators is that they do not remove particulates such as dust or pollen from the air. This includes the particles which are primarily responsible for allergic reactions.
Does ozone remove carbon monoxide?
Other studies have also (PDF) noted that ozone cannot effectively remove carbon monoxide or from outside. If used at concentrations that do not exceed public health standards, ozone applied to indoor air pollution does not effectively remove viruses, mold, bacteria, or other biological pollutants.

How does ozone work?
Ozone generators produce electro-charged ozone that attaches to odor-causing microbes. Ozone is comprised of three oxygen atoms - the third can attach to molecules of other substances and therefore change their molecular structure, which can prevent them from giving off odors.
How long does it take for ozone to neutralize?
Most ozone generators output ozone in quantities several times the recognized safety amounts. It usually takes up to 60 minutes after the generator cycle ends for the ozone to neutralize into oxygen that is safe to breathe. Air purifiers are one way to improve your indoor air quality. (Image credit: Kenmore)
Does ozone cause odors?
Ozone generators penetrate carpets, walls, window treatments, light fixtures and air ducts with ozone, so it's believed the gas will tackle hard-to-reach causes of odors. However, according to the EPA, ozone generators are not as effective as some would have you believe.
Is it safe to breathe ozone?
Ozone is dangerous to breathe in large quantities. There are federal standards of how much ozone is safe to inhale, ranging between 0.05ppm and 0.10ppm. Some states, such as California, have even lower thresholds. Most ozone generators output ozone in quantities several times the recognized safety amounts.

Does an air purifier remove odors?
The best air purifiers are one option to clean dust, pollen and other particles from the air, but they're less effective at removing odors. Respiratory issues can often be caused or exacerbated by poor indoor air quality, but odors and mold are often symptoms, and not causes, of this.
Can ozone generators remove carbon monoxide?
For example, "ozone generators are not effective in removing carbon monoxide". Research has found that "some of the potential by-products produced by ozone’s reactions with other chemicals are themselves very reactive and capable of producing irritating and corrosive by-products".
Why do people use ozone generators?
When a house has a mold problem, people often use ozone generators to address the more obvious issues, like strong odors. However, you must be careful that the source of the mold (i.e. a leaking water source, fungal growth, etc.) is properly remediated by professionals. Ozone generators may mask the smell, but you will need to ensure you are not continuing to live with toxic mold growth by eliminating the root of the problem.

If you decide to rent an ozone generator, you can take some steps to reduce the time required for the generator to be in use. Try cleaning the affected area with white vinegar or baking soda etc. to attack the source of the smell and possibly eliminate the problem in a less intensive manner.
How long can you run ozone generators?
Depending on the extent of the problem, ozone generators can be run for several hours in these transportation vehicles (while unoccupied) to help eliminate some of the odors. However, as we discussed, the efficacy of ozone on VOCs is not certain and may be limited if applied in a short time period.
What are the effects of ozone on VOCs?
Reactions between excessive residual ozone and unsaturated VOCs may even lead to the formation of harmful intermediates such as aldehydes, organic acids and fine mode particles. Furthermore, the reaction rates of ozone with most VOC’s were slow in indoor environments.
Can ozone cause mold?
However, ozone can also be an unpleasant smell as well, so mitigating the mold issue this way may just be substituting one issue for another. Furthermore, it is likely that ozone generators are unable to remedy the cause of the mold, so it is still only a partial solution if at all.
Purpose
- Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often the vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution. For almost a century, health professionals have refuted these claims (...
Controversy
- Some vendors suggest that these devices have been approved by the federal government for use in occupied spaces. To the contrary, NO agency of the federal government has approved these devices for use in occupied spaces. Because of these claims, and because ozone can cause health problems at high concentrations, several federal government agencies have worked in co…
Safety
- The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irr…
Terminology
- Manufacturers and vendors of ozone devices often use misleading terms to describe ozone. Terms such as \"energized oxygen\" or \"pure air\" suggest that ozone is a healthy kind of oxygen. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Several federal agencies have established health standards or recommendations to limit huma…
Environment
- The phrase \"good up high - bad nearby\" has been used by the U.S. Environmental Protection Agency (EPA) to make the distinction between ozone in the upper and lower atmosphere. Ozone in the upper atmosphere--referred to as \"stratospheric ozone\"--helps filter out damaging ultraviolet radiation from the sun. Though ozone in the stratosphere is protective, ozone in the at…
Effects
- There is evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odor-causing chemicals.
Results
- Results of some controlled studies show that concentrations of ozone considerably higher than these standards are possible even when a user follows the manufacturers operating instructions.
Models
- There are many brands and models of ozone generators on the market. They vary in the amount of ozone they can produce. In many circumstances, the use of an ozone generator may not result in ozone concentrations that exceed public health standards. But many factors affect the indoor concentration of ozone so that under some conditions ozone concentrations may exceed publi…
Mechanism
- The actual concentration of ozone produced by an ozone generator depends on many factors. Concentrations will be higher if a more powerful device or more than one device is used, if a device is placed in a small space rather than a large space, if interior doors are closed rather than open and, if the room has fewer rather than more materials and furnishings that adsorb or react …
Risks
- Manufacturers and vendors advise users to size the device properly to the space or spaces in which it is used. Unfortunately, some manufacturers recommendations about appropriate sizes for particular spaces have not been sufficiently precise to guarantee that ozone concentrations will not exceed public health limits. Further, some literature distributed by vendors suggests tha…
Summary
- Ozone has been extensively used for water purification, but ozone chemistry in water is not the same as ozone chemistry in air. High concentrations of ozone in air, when people are not present, are sometimes used to help decontaminate an unoccupied space from certain chemical or biological contaminants or odors (e.g., fire restoration). However, little is known about the chemi…
Management
- Of the three, the first approach source control is the most effective. This involves minimizing the use of products and materials that cause indoor pollution, employing good hygiene practices to minimize biological contaminants (including the control of humidity and moisture, and occasional cleaning and disinfection of wet or moist surfaces), and using good housekeeping practices to c…
Prevention
- The public is advised to use proven methods of controlling indoor air pollution. These methods include eliminating or controlling pollutant sources, increasing outdoor air ventilation and using proven methods of air cleaning.
