ULTRAZONE OZONE GENERATOR, 1922

Devices generating high levels of ozone, some of which use ionization, are used to sanitize and deodorize uninhabited buildings, rooms, ductwork, woodsheds, boats and other vehicles.

In the U.S., air purifiers emitting lower levels of ozone have been sold. This kind of air purifier is sometimes claimed to imitate nature's way of purifying the air without filters and to sanitize both it and household surfaces. The United States Environmental Protection Agency has declared that there is "evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odour-causing chemicals or "viruses, bacteria, mould, or other biological pollutants." Furthermore, its report states that "results of some controlled studies show that concentrations of ozone considerably higher than these [human safety] standards are possible even when a user follows the manufacturer’s operating instructions."

The US government successfully sued one company in 1995, ordering it to stop repeating health claims without supporting scientific studies, if that is the case we think it should be classed as Quackery.
