Indoor Air Quality Systems
Healthy Climate®

Pollutants like pollen, bacteria, viruses and dust find their way into your home’s
air every day. That’s a problem, because these particles and bioaerosols can
cause poor indoor air quality, which impacts both your home environment
and your health. At the very least, poor air quality can make your home
uncomfortable. And, if you’re one of more than 50 million Americans who
suffer from allergies,*** poor air quality can make your home very unhealthy.
SOLUTIONS FOR A CLEANER, HEALTHIER HOME ENVIRONMENT
A Healthy Climate®high-efficiency particulate air (HEPA) bypass filtration
system can go a long way toward improving the air you breathe. Using
the same filtration technology found in hospital operating rooms and
science labs, a HEPA system removes nearly all allergy-inducing
contaminants, including even the smallest particles and bacteria. It filters
and freshens the air throughout your home, so you can breathe easier.

Near-perfect particle filtration
Healthy Climate®HEPA bypass
filtration systems are 99.97%
efficient at removing small particles
at 0.3 micron—contaminants
that standard filtration systems
can’t effectively stop. Particles
smaller than 2.5 microns pass
through the lungs and into the
bloodstream, increasing the
likelihood of illness. The HEPA
system minimizes your exposure to
potentially harmful pollutants.

Powerful, yet quiet, performance
The system acts like a vacuum, drawing
air out of the return duct, cleaning
it and then cycling it back into your
home. The system can also operate
independently of your HVAC system to
isolate and filter a specific area of your
home. The filtration process involves
three main steps:
1) Contaminated air passes through
a pre-filter, trapping large dirt and
dust particles.
2) Air then flows through the HEPA
filter, which captures nearly
all remaining particles and
bioaerosols.
3) Finally, air passes through a
charcoal/carbon filter in the
standard unit to absorb odors
and chemical fumes. An optional
carbon canister is available for
enhanced absorption.
