Introduction
Congratulations! You will quickly realize that you
have purchased a very effective air cleaning system.
It incorporates state of the art HEPA (High Efficiency
Particulate Air) technology.
Your Healthy Climate HEPA system comes with a
limited warranty. With proper attention to its care and
maintenance, you will receive optimum performance.
If your indoor air has abnormally high concentrations
of particulates, the life span of the filter media may
be shortened. Excessive particulates in the air will
reduce the expected life of the HEPA filter. Under normal conditions the HEPA filter will last from two to five
years.
The optional activated carbon canister has a finite limit
as to the amount of odor or other gaseous volatile
organic compounds (V.O.C.’s) that it can adsorb. The
higher the concentrations, the shorter the expected
life. Higher humidity may shorten the life of the carbon

canister. Under normal conditions, the carbon canister
will last up to 6 months.
Initially, the HEPA filter’s particulate removal efficiency
improves with use. However, the air flow through the
HEPA filter media will decrease, as dust builds up on
the filter, thus lowering its ability to circulate and clean
as much air as when it was new. If the air flow through
your unit is noticeably reduced, you can inspect the
carbon pre-filter and HEPA filter to see if they should be
replaced. Replacement of the carbon pre-filter every 12
months will help extend the life of the HEPA filter.
Please contact your local Healthy Climate® dealer
regarding replacement of filters, warranty information
or if you have any questions or concerns about the
performance of your HEPA system.
NOTE: This filtration system is an ADDITIONAL
filter, and does NOT replace the existing air
handler/furnace system filter.
To significantly increase the quality of air in your home, bringing in FRESH AIR is strongly recommended.
Filtering outdoor air with a HEPA/Carbon filter will remove many of the contaminents and irritants from
outdoor air.
The HEALTHY CLIMATE® HEPA Air Filtration System when used with the HEALTHY CLIMATE® LVCS or
HRV/ERV and Dehumidifers will filter ultrafine particulates, chemicals, odors and other toxins out of the
new air entering the home. Bringing in fresh air that is clean and filtered will increase the quality of the air
in the home. Slight positive pressurization of the home will prevent unwanted contaminents from walls
and attics sneaking in! Ask your Healthy Climate® Dealer about installing a system that will introduce
fresh air. “Service and Application Note IAQ-06-2”

General Information
Media Filters
Media filters strain particulates from the air. The filter
media needs to have tiny holes to allow air to pass
through, but not particulates. Filter types vary for all
sorts of purposes. The most effective and proven filter
media is HEPA. HEPA filter media is 99.97% efficient
at capturing particles which are 0.3 micron in size or
larger.
Inner Charcoal Filter/Carbon Canister
Carbon media is used to capture chemicals and odors,
also referred to as V.O.C.’s. Chemicals and odors
cannot be captured with media type filters. Activated
carbon attracts chemicals and odors and holds them.
If air passes through the carbon filter before particulates are removed, the surface of the carbon quickly
gets covered with particulates, rendering it ineffective at capturing chemicals and odors. If particulates
are removed from the air with a HEPA filter, virtually
the entire surface area of the carbon can be used to
capture chemicals and odors. This increases the efficiency and filter life of the inner charcoal filter.
Separate HEPA and Carbon Filters
HEPA and carbon filters have different life spans. It is
important for a filtration system to keep the filter components independent from each other, so that the filter
that is dirty/saturated can be changed. This is more
economical than a system where you need to throw
out two or three filters when only one needs changing.
The HEPA System’s 3 Stage Filtration Process
The 3 stage filtration process is used to create a very
effective filtration system. Each filter is independent
and can be changed individually.
• Stage 1: Carbon pre-filter - The inexpensive carbon
pre-filter removes larger particulates from the air, thus
prolonging the life of the HEPA filter.
• Stage 2: HEPA - The HEPA filter removes 99.97%
of particulates 0.3 micron and larger. The cleaned air
then passes through the third stage filter.
• Stage 3: Inner Charcoal Filter - The inner charcoal
filter is 1/2 an inch thick to give it plenty of surface
area for removing chemicals and odors from the air.
OPTIONAL UPGRADE: The stage 3 Inner Carbon
Filter may be replaced by an optional heavy duty
granulated coconut shell carbon canister. The VOC
Canister offers increased capacity removal of chemicals and odors. Filled with granulated coconut shell
carbon, the surface area available for adsorption of
gas and chemical pollution is approximately 60 to
70 million square feet. The filter upgrade captures
many contaminents in the air and holds them safely in
the carbon. The increased capacity of this filter also
extends the performance life. The VOC Canister also
captures low level ozone from outside air and uses
the ozone to turn the filter into an active system which
actually destroys VOCs rather than just holding them.

* Chart based on homes with 8 ft. ceilings.
Notes:
• Industry experience indicates that one (1) air change per hour generally provides adequate air cleaning. Actual
results will depend on multiple factors such as outdoor particulate levels, infiltration rate, indoor activities etc.
• The chart is based on an infiltration rate of 0.3 air changes per hour, which is typical for residential construction.
Higher infiltration typically brings in more particulates and thus increases the air changes per hour needed for
HEPA bypass filtration. Other particulate sources in the house will require higher air changes per hour.
• The chart is based on continuous operation of the HEPA system. If the HEPA system is cycled, the capacity
of the filter needs to be increased. For example, if the HEPA system is “ON” only half the time, then the capac
ity of the unit needs be doubled or additional units need to be installed.
• The more air changes per hour provided, the more effective a HEPA system will be. People with sensitivities
may desire a higher number of air changes per hour for cleaner air.
