Dave Lennox Signature™ Collection PureAir™ Air Purification System

MERV 9, 4" pleated filter

™

for removal of most small,
breathable particles down
to 1 micron

Only single indoor air
quality system to attack all
three classes of contaminants:
small, breathable particles;
airborne mold spores,
bacteria and viruses; and
odors/chemical vapors

Industry-exclusive air
purification technology

Innovation never felt so good.

Pollutants such as dust, pollen, bacteria and viruses find their way into your

home’s air every day. These pollutants can cause poor indoor air quality, which

impacts both your home environment and health. The PureAir™ Air Purification

System is the most complete way to clean the air and help keep it free of

potentially harmful contaminants. It uses patented photocatalytic oxidation

technology to filter, purify and freshen the air, and it combines all these

capabilities in one integrated system.

CLEANS THE AIR IN YOUR HOME BETTER THAN ANY
OTHER SINGLE SYSTEM YOU CAN BUY

The PureAir System controls everything from microscopic dust mites and mold

spores to infectious bacteria and viruses. And it’s the only indoor air quality

system that safely removes and destroys odors and chemical vapors. So when

you put the power of the PureAir System to work in your home, you’ll not

only breathe cleaner air—you’ll also breathe a sigh of relief.

WARRANTY

5-year limited warranty
on covered components.

Highly effective filtration

Almost nothing gets past the

revolutionary PureAir System. Rated

MERV 9 for filtration efficiency,

this system captures and destroys

particles and bioaerosols as small

as 1 micron—contaminants that

standard filtration systems simply

can’t stop.

Benefits of good indoor air quality

Health – An environment

virtually free of potentially harmful
contaminants.

Cleanliness – A home environment

with a minimal amount of dust, dirt
and odors.

Comfort – Proper humidity, air

distribution and temperature control.

THREE CLASSES OF
AIR CONTAMINANTS

Particles—Pollen, dust
mites, dirt, pet dander.

Particles are any
substances measuring
less than 100 microns
in diameter.

Bioaerosols—
Bacteria, viruses,
mold spores, fungi.

Microscopic living
organisms that grow
and reproduce in
warm, humid places.

Odors/Chemical
Vapors—Pet odors,

cooking smells,
perfumes, tobacco
smoke, chlorine,
cleaning supplies,
paints, solvents.

Air contaminants in
the form of gases.

The Mayo Clinic has found

that air cleaners attached to

ODORS/CHEMICAL VAPORS IN THE HOME

Odors and chemical vapors
can come from many different
sources inside and outside
the home. Once inside the
home, these pollutants
circulate through the
ductwork, entering every
room and living space. Using
innovative air-purification
technology, the PureAir
System helps remove the
hundreds of odors/chemical
vapors that can contaminate
your home’s air.

The effects of odors and chemical vapors on your

comfort and health depend on the types and

concentrations of them within your home, as well as

your individual sensitivity. Generally, the more odors and

chemical vapors in the home, the more likely you are to

suffer an adverse reaction such as dizziness or shortness

of breath. This is especially true if you have asthma or

* One unit should be used in each air handler and model selection should be based on the size of the air handler. PureAir units should NOT be placed in the

supply side (after the heater) because the higher temperature may compromise system performance.

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

Catalyst on Insert

UVA LightPleated Filter

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.
