Ozone

Right from the start, we should tell you that Modern Alchemy Air Purifiers does not recommend, condone or sell any ozone air cleaners. Why? Because they are not only suspect in their actual air cleaning abilities, but according to the Environmental Protection Agency (EPA), can pose serious risks to your health.

Ozone is a highly reactive toxic gas and a major component of photochemical smog. While two atoms of oxygen form the basic oxygen molecule (O2), the ozone molecule is composed of three atoms of oxygen (O3). Ozone is highly unstable, with the third oxygen atom easily detaching from the molecule and re-attaching to molecules of other substances, thereby altering their chemical composition.

Ozone air cleaners work by intentionally producing and releasing ozone gas into the air. Manufacturers claim that the ozone cleans indoor air by breaking down odours and other contaminants through a chemical reaction (i.e., bonding with the third oxygen atom), thus rendering contaminants harmless.

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 organic material inside the body, with potentially harmful health consequences. When inhaled, small amounts of ozone can result in throat irritation, coughing, shortness of breath and chest pain. Ozone can also aggravate chronic respiratory system diseases such as asthma and compromise the body’s ability to fight respiratory infections. In high enough concentrations, it can even cause lung damage.   Read more about the effects of ozone on your health.

Manufacturers and vendors of ozone air cleaners often use misleading terms to describe ozone. Terms such as "energized oxygen," “super oxygenated” or "pure air" suggest that ozone is a healthy kind of oxygen, when it is in fact a toxic gas with vastly different chemical and toxicological properties from oxygen. In fact, health standards and guidelines have been created by various federal agencies to limit human exposure to ozone.

Available scientific evidence shows that ozone air cleaners are generally ineffective at removing indoor air contaminants unless they produce concentrations of ozone that exceed public health standards. In other words, if it is not generating enough ozone to make you ill, it is also not generating enough ozone to clean the air.

While the use of ozone air cleaners that generate massive amounts of ozone may sometimes be necessary to help decontaminate unoccupied spaces from chemical or biological contaminants (e.g., fire restoration, flood damage, sewage backup), in these instances, conditions are carefully controlled to ensure that people and pets are not exposed to the ozone. Ozone can also adversely affect indoor plants, as well as damage materials such as rubber, electrical wire coatings, fabrics and art work containing susceptible dyes and pigments. Also, little is known about the chemical by-products left behind by these processes in regard to long-term health effects.

To sum up, Modern Alchemy Air Purifiers strongly recommends that you do not purchase an ozone air cleaner unless it will not be used in the presence of people or pets.
