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
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
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.
