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 Hawk Environmental 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 (VOC) 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
should last up to 12 months.

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
PHGLDLV+(3$+(3$ILOWHUPHGLDLVHIILFLHQW
at capturing particles which are 0.3 micron in size or
larger.
Carbon Filters
Carbon media is used to capture chemicals and odors,
also referred to as VOC. Chemicals and odors cannot
be captured with media type filters. Activated carbon
collects chemicals and odors in a process called
adsorption. 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 carbon 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.

General Information
Product Application Guidelines
Size of House vs. Air Changes per Hour
* 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.
• Generally speaking, 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.

Preparation:
Here are some things to consider as you decide where to
install the HEPA system.
Location:
• Make sure there is room to open the HEPA filter access
panel for filter changes/inspections.
• Keep the HEPA system in a location where you can still
access the air handler/furnace filter.
• Keep the HEPA system away from possible water
damage.
• Vibration pads will reduce vibration for installations where
the unit is placed on the floor.
• Install HEPA system on floor or suspended platform. If
the unit is suspended, screws must not penetrate through
the cabinet. Make sure that you have the proper chains/
straps/joists and equipment to keep unit secure.

Independent Operation:
The HEPA system can be used independently of any other equipment! The intake and outflow of the filtration
system can be ducted into the same room to create a cleaner environment almost anywhere. The intake or outflow
can also be ducted elsewhere. The intake and outflow should be installed on opposite sides of the room; however,
this varies according to your specific needs.

Dealer Filter Change Instructions
It is recommended that gloves and a filtered
breathing mask be worn during filter replacement
to avoid breathing particulates (dust, mold, pollen,
etc.) captured on the filter that become airborne
during the filter(s) change.
The old filters should be wrapped and sealed in
plastic bags immediately upon removal from the
unit, to avoid distributing particles throughout the
house during the process of disposal.
1. Accessing the filters
a. Remove safety screw(s) from HEPA filter access
panel.
b. Unlatch the two retaining clips and lift off HEPA filter
access panel.
c. Bracing the unit so it does not move, turn the HEPA
cartridge counter-clockwise and lift/pull out.
2. Pre-filter Replacement
a. Pull the pre-filter up and off the unit. NOTE: The
pre-fiter may contain contaminants. Remove it slowly
to avoid releasing particles back into the air.
b. Foam pre-filters can be washed several times.
Wash by hand in warm water. Let dry completely
before placing back onto the HEPA cartridge.
b. If replacing the filter, remove plastic
shrink wrap from the new pre-filter.
c. Stretch the new/washed filter around the top of
the HEPA cartridge and slide it down into place.
3. Inner Carbon Filter Replacement
a. Look inside the HEPA cartridge to locate the two
ends of the inner carbon filter.
b. Pull one end of the old inner carbon filter in and
bend it into a loose roll so it can be removed.
c. Remove the inner carbon filter from the HEPA
cartridge.
d. Remove plastic shrink wrap from the new inner
carbon filter.
e. Unroll the inner carbon filter and roll it up in the
opposite direction (this makes the filter follow a
more contoured profile against the inner HEPA filter
surfaces and helps keep it in place), place the rolled
inner carbon filter inside the HEPA cartridge and
