Question:
Alpine is to make no claim or representation that a sensor installed on any of its air cleaning machines is capable of controlling the ambient level of ozone in indoor air. ?

Answer: Alpine Industries Ordered to Stop Unsubstantiated Claims for Ozone Generators

Alpine Industries, of Greeneville Tennessee, manufactures and distributes various consumer and commercial products. Its best known products are air-purification devices. These are ozone generators that circulate room air through an electrically charged plate. The plate converts the oxygen into ozone that is recirculated into the room by a fan in the unit [1].

The company states that its distributors have sold more than three million of its air-purification systems since 1987 [2]. In January 2000, a federal court ordered the company to stop making health claims for its ozone generators [3,4].

Safety Concerns

There is no difference between outdoor ozone in smog and ozone produced by an "air cleaning" device. The U.S. Occupational Safety and Health Administration (OSHA) limits ozone exposure in industrial settings to 100 parts per billion (ppb) over an eight-hour day, six days per week. The FDA has set a limit of 50 ppb for the ozone from electronic air cleaners used as medical devices [1].
