SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Im-
proper installation may damage media air cleaner.
Recognize safety information. This is the safety al ert symbol . When the safety alert symbol is present on equipment
or in the instruction manual, be alert to the potential for personal injury.
Understand the sig nal words DANGER, WARNING, and
CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most se rious hazards which will re sul t
in severe personal injury or death. WA RNING signifies a haz ard which could result in personal injury or death. CAUTION
is used to identify unsafe practices which would result in minor
personal injury or property damage.
Before beginning any installation or modification, be certain that the main line electrical disconnect switch is in the
OFF position. Electric shock could result. Tag disconnect
switch with suitabl e warn ing labe ls.
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform the basic maintenance
functions of replacing filters. All other operations should be
performed by trained service personnel. When working on airconditioning equipment, observe precautions in the literature,
tags and labels attached to the unit, and other safety precautions
that may apply.
Follow all safety codes. Wear safety glasses and work
gloves.
GENERAL
The Builder’s Box Media Air Cleaner is designed to remove atmospheric and household dust, pollen, mold spores,
bacteria, fungi, insecticide dust, animal dander, coal dust,
mites, cooking smoke and grease, tobacco smoke, and other
particles down to 0.3 micron (1/84,000 in.)
Airborne pollutants are carried through the return air ducts
of the heating/cooling system to the media air cleaner. The particles are captured by the filter.
The media air cleaner can be easily upgraded to an electronic
air cleaner for additional air filtration. Additional clearance
above the media air cleaner is required for electronic air cleaner
upgrade.
Regular maintenance (replacement of filters) is required by
the home owner.
COMPONENTS
See Fig. 1 for a description of the media air cleaner. See
T able 1 for media air cleaner specifications.
Cabinet —
nized steel. Holes are provided in the cabinet for easy mounting
in the ductwork or air-handling equipment. See Fig. 2 for cabinet dimensions.
Filter —
will not shred or absorb moisture. The unique design of the filter includes a structured density gradient with a polarized
charge for higher initial and sustained efficiency. The filter media is supported by an open steel mesh and enclosed by a high
strength, beverage board. The filters have an Underwriters’
Laboratories Class 2 rating.
The efficiency of the filter is based on ASHRAE (American
Society of Heating, Refrigeration and Air Conditioning Engineers) Standard 52.2P. The maximum veloci ty is 500 ft/min.
An arrow indicates direction of airflow.
The cabinet is constructed of heavy gage galva-
The filter is constructed of polyolefin fibers that
Manufacturer reserves the right to
discontinue, or change at any time,
specifications or designs without notice
and without incurring obligations.

INSTALLATION
Location —
return air duct, as close to the blower compartment as possible.
This location provides the most even airfl ow across the filter
and allows the media air cleaner to keep the system motor and
blower clean. See Fig. 3. When choosing location, there must
be adequate room to remove filters.
NOTE: Be sure to notify home owner not to install any device
within 3 ft from the side of the media air cleaner after installation is complete. Regular servicing of the medi a air cleaner is
required. A 3 ft clearance is required to remove filters for
maintenance or replacement.
IMPORTANT: The media air cleaner will cause
more of a restriction of your heating or cooling system than a regular furnace filter due to its increased
efficiency. As the filter collects contaminants, the
pressure drop increases. The media air cleaner is not
recommended in systems where pressure drop is
critical. See Table 2 for pressure drop information.
The media air cleaner must be installed in the

INSTALLATION LOCATION WITH HUMIDIFIER — If
a separate humidifier is purchased, it should be installed in the
furnace warm air duct. However, a humidifier may be installed
in the return air duct without causing problems to the media air
cleaner. Care must be taken to ensure that the humidifier does
not leak, as this may cause damage to the media air cleaner and
mineral deposits on the filter.
An atomizing-type humidifier should only be installed
downstream of the media air cleaner. If the atomizing-type humidifier is installed upstream, high humidity, salts, and minerals may damage the filter and cause service problems.
If the atomizing-type humidifier must be installed upstream,
the atomizing-type humidifier must be installed as far from the
media air cleaner as possible.
INSTALLATION LOCATION WITH AIR CONDITIO NER — Whenever possible, the media air cleaner should
be installed upstream of the cooling coil. This location will
clean the air before it reaches the evaporator coil.
Media Air Cleaner Installation —
Perform the fol-
lowing to install the media air cleaner.
1. Remove the existing furnace filter. Thoroughly clean
the blower compartment and ductwork where the
media air cleaner is to be installed.
2. Remove access door by uns crewing plas tic kno b. Slide
the filter out of the cabinet.
3. Place cabinet in ductwork. Holes are provided to
attach cabinet to ductwork or equipment. If the adjoining ductwork is flanged, install the screws so that the
screw heads are inside the cabinet. This will help prevent damage to filters during removal for cleaning.
When the air duct does not fit the media air cleaner
opening, a gradual transition is recommended to
reduce air turbulence through the media air cleaner and
to increase its efficiency. There should not be more
than 20 degrees of expansion used on each side of
the transition fitting. Do not reduce ductwork to a
smaller media air cleaner or it will increase the velocity of airflow.
4. If the media air cleaner is installed adjacent to an
elbow or angel fitting, turning vanes are recommended
to improve air distribution across the filter.
5. After media air cleaner has been secured, seal seams
airtight with duct tape or caulking to prevent dust from
entering the system.
6. Replace filter. Make sure arrow on filter is pointing
towards the fan. Replace the access door.
