Are Ozone Generators Good for Allergies? - The Pros and Cons

Ozone is a molecule composed of three oxygen atoms, and it is this ability to react with other substances that forms the basis of the manufacturers' claims. Ozone generators are devices that produce ozone, and they are often marketed as a way to reduce indoor air pollution and improve air quality. But are ozone generators really effective in controlling allergies? The Environmental Protection Agency (EPA) has not approved ozone-generating devices for use in occupied spaces, and several federal government agencies have worked in consultation with the EPA to provide accurate information on the use of these devices. Ozone does not remove particulates such as dust and pollen, which are responsible for most allergies.

When inhaled, ozone can damage the lungs and worsen chronic respiratory diseases such as asthma. The Food and Drug Administration (FDA) requires that ozone production from indoor medical devices does not exceed 0.05 ppm, while the Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm for 8 hours. The EPA's National Ambient Air Quality Standard for ozone is a maximum average outdoor concentration of 0.08 ppm in 8 hours. Evidence shows that, at concentrations that do not exceed public health standards, ozone is not effective in eliminating many chemicals that cause odors, and it does not effectively remove viruses, bacteria, mold, or other biological contaminants. The actual concentration of ozone produced by an ozone generator depends on many factors, such as the power of the device, the size of the space, ventilation from outside air, and a person's proximity to the device.

Manufacturers and vendors advise users to size the device appropriately for the space.

The Pros and Cons of Ozone Generators

Pros:

• Ozone generators can reduce odors from smoke, pets, and other sources.
• They can reduce airborne bacteria.
• They can reduce mold spores.

Cons:

• Ozone generators are not effective in controlling indoor air pollution.
• They can cause health problems at high concentrations.
• They do not remove particulates such as dust and pollen.
• They do not effectively remove viruses, bacteria, mold, or other biological contaminants.

In conclusion, ozone generators are not effective in controlling indoor air pollution and can cause health problems at high concentrations. People should be aware of the potential risks associated with using these devices and should follow all safety instructions provided by manufacturers.
