WHAT TO EXPECT FROM YOUR MEDIA AIR CLEANER
Breeze 33 Media Air Cleaners effectively capture and remove a substantial amount of airborne particles through their top-performing pleated media filters. They can be easily mounted in any position within the return air duct of gas, oil, and electric forced warm air furnaces, as well as compressor cooling systems up to 5 tons. In addition, they require no electrical connections and minimal maintenance, needing only periodic media filter replacements.
WHEN INSTALLING YOUR MEDIA AIR CLEANER
- Please read instructions carefully – failure to do so could damage the product or could create a hazardous condition.
- Verify the rating specified in the instructions and on the product to ensure it is suitable for your application.
- Installer must be a trained/experienced service technician.
- After installation, refer to the Installation Checklist at the end of this document to ensure product operation.
APPLICATION CONSIDERATIONS
Designed to work with gas, oil, and electric forced warm air furnaces and with compressor cooling, the Breeze 33 Media Air Cleaners can also be used with heat pumps, provided the filter is changed regularly to prevent excessive pressure drop. However, they are not recommended for applications where pressure drop may be critical.
AIR CONDITIONING
Mount the Media Air Cleaners upstream of the evaporator coil in a cooling
system. The filter will assist in maintaining the cleanliness of the coil and
minimize the need for maintenance.
HUMIDIFIERS
The Media Air Cleaners are compatible with humidifiers. However, avoid
situations where water mist can come into contact with the media. If an
atomizing humidifier is used, the media filter will need to be replaced more
frequently due to mineral buildup from the water.
UV LIGHTS
Germicidal UV lights have the potential to deteriorate the media filter. To
prevent this, the UV light should be positioned out of the filter’s line of
sight or a minimum of 3 feet away. Failure to do so may result in the need for
more frequent filter replacements.
OFFSETS
If the duct connection to the furnace in a side installation provides less
than 7″ (178 mm) for mounting Media Air Cleaner, then you should attach an
offset to the elbow. See figure below.
TRANSITIONS
To achieve optimal air purification, ensure that the airflow is evenly
distributed across the surface of the media. If the duct size differs from the
media air filter cabinet, it is essential to implement gradual transitions.
Please adhere to the following instructions during the fabrication process:
- Implement gradual transitions to minimize air turbulence and enhance efficiency.
- Limit the expansion to no more than 20° (about 4″ per running ft. [100 mm per 300 linear mm]) on either side of a transition fitting. See figure below.

SHEET METAL
The Media Air Cleaner can be easily integrated into any new or current forced
air heating and cooling systems commonly found in residential settings. In
certain cases, transitions might be necessary to ensure optimal performance of
the Media Air Cleaner.
CAUTION: Sheet metal has sharp edges. Handle product carefully.
Failure to adhere to these instructions will lead to nullification of the warranty, incorrect installation, and additional service callbacks.
PERSONAL SAFETY
- Always wear protective eyewear when setting up the equipment.
- Avoid cutting into any HVAC or electrical wiring.
- Adhere to industry safety protocols and all plumbing, electrical, and mechanical regulations in your area.
CHOOSING A MOUNTING POSITION
The Breeze33 Media Air Cleaner mounts can be installed in any orientation within the return air duct, typically adjacent to the furnace blower compartment.
However, it is essential that the arrow on the cartridge aligns with the direction of airflow. Refer to Figs. 1-8 to determine the correct placement of the Media Air Cleaner for different setups.
NOTE: The Media Air Cleaner is robust enough to effortlessly bear the weight of the furnace and evaporator coil.

MOUNTING THE MEDIA AIR CLEANER
STEP 1 Review the Installation Plan
Place the cabinet on the floor in the exact orientation it will be installed
in.
Test inserting and removing the cartridge to ensure that there is enough
clearance for easy removal and replacement of the cartridge.
STEP 2 Fasten the Cabinet to the Furnace
a. Adjust the cabinet to align with the return air opening.
b. Position blocks underneath the cabinet to ensure the unit is stable.
c. Make an opening in the furnace to correspond with the cabinet opening.
d. Securely affix the cabinet to the furnace. Connect the unit directly
or use a starting collar in the furnace opening. Either drill holes and use
sheet metal screws or rivets to fasten, or utilize slip joints. If drilling
holes, use locking pliers to assist in holding the unit steady while drilling.
STEP 3 Fasten Cabinet to Ductwork
Secure the cabinet’s side to the ductwork using the suitable method of sheet
metal screws, rivets, or slip joints.
STEP 4 Connect Ductwork
a. Join the vertical duct section with the elbow. If the vertical descent
of the duct is under 7″ (178 mm) from the furnace’s side, adjust the
horizontal trunk or connect an offset fitting to the elbow.
b. Ensure that the vertical duct is connected to the horizontal trunk
when the ductwork is correctly aligned.
STEP 5 Seal Joints
Make sure all connections in the return air system between the media air
filter and the furnace are properly sealed to avoid dust contamination in the
purified airflow.
STEP 6 Install Filter Cartridge
Insert the filter cartridge into the cabinet, ensuring that the arrow on the
cartridge is facing the direction of airflow. Then replace the access door by
inserting the tab on the bottom of the door into the slot in the cabinet.
Finally, swing the door closed and press it into place.
INSTALLATION CHECKLIST
- Visually check the installation and make sure that:
- Airflow follows the direction of the arrow indicated on the media air filter cartridge.
- Proper installation of transitions, if applicable, are ensured. Sealing of joints in the sheet metal between the media air filter and furnace is completed.
- All sheet metal connections are fully assembled.
- Original furnace filter has been taken out and the blower compartment has been cleaned.
When you have verified that the steps above has been completed:
- Replace any access doors that were removed during the installation process.
- Ensure that the furnace or cooling system runs through a full cycle to verify that it is functioning as intended.
