Three main components

The revolutionary PureAir™ Air Purification System consists of a MERV 16 Precision Pleat™ filter, two 55-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

photocatalytic­oxidation (PCO) that combines three of nature’s 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 catalyst and water vapor in the air, that destroy organic compounds

Three fast, effective steps

The PCO process involves three steps:

1)The Precision Pleat MERV 16, 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 UVA lamps,† 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 hydroxyl radicals attack the carbon components of the odors and chemical vapors, breaking them down into carbon dioxide and water.

The PureAir™ Air Purification System is the only single system that effectively combats all three types of contaminants.
