					A375UV Photo Catalytic Oxidation Technology

A large contributing factor to poor indoor air quality is the release of VOC’s. VOC’s are organic
(carbon based) and are emitted as gases from a variety of products. Also called hydrocarbons,
VOC’s vaporize due to sufficiently high vapor pressures.

The common indoor sources of VOC’s are paint, carpeting, copiers/printers, laminated furniture,
wood preservatives, paint thinner, glues, permanent markers, cosmetics and certain aerosols and
plastics. If there is not sufficient ventilation with the outdoor air and VOC’s are present, the indoor
pollution levels can be up to 10 times higher than the outdoor air according to the EPA. And that
includes urban areas.

The A375UV includes UV-PCO(UV Photo Catalytic Oxidation) technology to reduce the levels of
VOC’s. The interaction of UV-C light and a permanent titanium dioxide (TiO2) grid serves as a
photocatalyst to carry out hydrolysis (ie.to break water into hydrogen and oxygen). As TiO2 is
exposed to UV light, it becomes increasingly hydrophilic; thus, it can be used reduce
concentrations of airborne pollutants such as volatile organic compounds into harmless elements.
As a safety feature, the UV-C lights and titanium dioxide grid are located on the inner most
section of the A375UV to prevent the user from coming into contact with the rays of the UV lights.
