The PureAir™ air purification system helps to signifi-
cantly reduce levels of airborne volatile organic
compounds, cooking odors, common household
odors, airborne dust particles, mold spores, and
pollen in residential spaces. The PureAir™ air purifi-
cation system
(cased model)
includes a MERV 9
pleated filter, UVA lamps, and a metal insert that is
coated with a titanium dioxide catalyst. As air enters
the system, a percentage of airborne particles and
bioaerosols, such as mold and bacteria, ranging in
size down to .3 microns, are captured by the pleat-
ed filter. The smaller airborne particles, odors, and
chemicals continue through the system. The UVA
lamp activates the catalyst on the metal insert. The
catalyst combines with water vapor in the air to form
hydroxyl radicals that destroy a percentage of the
remaining odors and chemicals.
In laboratory & field tests, we found greater than
(TVOC) within 24 hours of initial installation and
operation of the PureAir™ air purification system.
When the system is first started, it may take up to 48
hours to reduce the airborne chemicals that have
built up in your home over a long period of time.
After that period, there will be a balance between
chemicals emitted inside your home and chemicals
removed by your PureAir™ air purification system.
Please refer to the included Homeowners IAQ guide
for other measures to improve indoor air quality.
The PureAir™ air purification system is NOT intended to be used for
removal of active mold growth or continuous source of high levels
of chemicals in the air. For existing mold growth, the mold must be
appropriately removed PRIOR to installation of your PureAir™ air
purification system.
