Catalyst on Insert, Pleated Filter, UVA Light, Lights

Three main components

The revolutionary Healthy Climate® Series PureAir™ Air Purification System consists of a pleated filter, four (PCO-12C) or six (PCO-20C) 17-watt UVA lamps and a metal insert that

is coated with a catalyst that’s activated by ultraviolet (UVA) light.

Three powerful air purifiers

The PureAir System reduces concentrations of pollutants through a process called photocatalytic oxidation (PCO) that combines nature’s three most powerful air purifiers:

◆Ultraviolet light (UVA)†

◆Titanium dioxide catalyst, a nontoxic substance found in everyday household products

◆Hydroxyl radicals, formed through the chemical reaction of the UVA light, catalyst and airstream, destroy organic compounds

Three fast, effective steps

The PCO process involves three steps:

1)The pleated, 4" MERV 9 filter captures particles and bioaerosols as small as 1 micron, removing them from

the airstream.

2)As the odor- and chemical vapor-filled airstream flows over the ultraviolet light, the airstream is exposed to the catalytic surface (titanium dioxide-coated metal filter).

3)The light energy and water vapor in the air activate the titanium dioxide catalyst, which generates hydroxyl radicals. These particles break down the odors and chemical vapors into carbon dioxide and water. The conversion process occurs as the carbon components of the odors and chemical vapors react with the hydroxyl radicals, creating carbon dioxide and water vapor.
