Pure Air System
Three powerful air purifiers
The PureAir System reduces concentrations of
of pollutants through a process called
photocatalytic oxidation (PCO) that combines
three of nature's most powerful air purifiers:
- Ultraviolet light (UVA)
Titanium dioxide catalyst, a nontoxic
substance found in everyday
- . Hydroxyl radicals, formed through the
chemical reaction of the catalyst and water
vapor in the air, destroy organic compounds
Three fast effective steps
The PCO process involves three steps:
1) The Precision Pleat MERV'l6,5" filter captures particles and bioaerosols as small as .01 micron, removing them from
the airstream-contaminants that standard filtration systems simply can't stop.
2) As the odor- and chemical vapor-filled airstream flows over the ultraviolet lamps,t the airstream is exposed to the
catalytic su rface (titanium dioxide-coated metal f i lter).
3) The light energy and water vapor in the air activate the titanium dioxide catalyst, which generates hydroxyl radicals.
These hydroxyl radicals attack the carbon components of the odors and chemical vapors, breaking them down into
carbon dioxide and water.
