The HEPA Air Cleaner has been designed to remove particulate such as atmospheric and household dust, coal dust, insecticide dust, mites, pollen, mold spores, fungi, bacteria, viruses, pet dander, cooking smoke and grease, tobacco smoke and more. It also removes odors with the Carbon Prefilter.


  • Helps provide relief from allergies, asthma, and other respiratory illness.
  • Helps reduce housekeeping time and redecorating costs.
  • Helps provide a healthier, more comfortable environment, year-round.

How It Works:-

Millions of airborne pollutants are carried through the return air ducts of the heating/cooling system. HEPA Air Filtration Systems has been designed to be ducted to the return air duct. A portion of this return air is bypassed through an 8 inch intake duct on the top of the unit and passes through a 2-stage filtration system. The Activated Carbon Prefilter (activated carbon impregnated polyester filter) first removes lint and odors before they enter the HEPA filter. Smaller particles then pass through a long-life, HEPA (High Efficiency Particulate Air) Filter which captures 99.97% of particles 0.3 micron (1/84,000 of an inch) and larger. This HEPA filter has more than 100 ft² of collection surface area. Clean air is discharged through a 6 inch duct, back into the return air duct.


The HEPA Air Cleaner should be located as close to the return air duct as possible. This allows for shorter lengths of ducting which helps keep the static pressure lower. The unit can be adapted to mount on a wall or be suspended from the ceiling. Care should be taken to keep the unit away from an area where there is a possibility of moisture leaking on to it. Ensure there is 36 inches in front of the unit to remove the filters for cleaning or replacing.

NOTE: If the unit is going to be mounted on it’s back you must contact the distributor for special mounting kit


  1. Remove any packaging or plastic from filters before installing. See Maintenance for instructions to remove the filters. Cut wire ties from filter holddown bar.
  2. When the unit is shipped, the intake and exhaust collars are reverse mounted to prevent damage in shipping. The intake collar must be removed and reattached with the collar ring facing out. The exhaust collar can be mounted on one of three sides of the unit with the ring out. The other two sides will be covered with the exhaust covers. These covers must be installed for the unit to operate properly.
  3. An inlet collar is provided on the unit to allow a flexible 8 inch intake duct, from the cold air return, to be attached. The 8 inch intake must be drawn from the cold air return duct at a location that will be ahead of the clean exhaust air, that will be returned to the duct from the Air Cleaner.
  4. A duct adapter and a length of 8 inch flexible hose or duct is required to attach between the 8 inch intake collar and the existing cold air return duct. When running the hose, make sure that there are no kinks or sharp bends that will impede the air flow to the unit. Secure and seal the hose and connections to prevent air leakage.
  5. The 6 inch exhaust collar can be conveniently mounted on one of three sides of the unit. A duct adapter and a length of 6 inch flexible hose or duct is required to attach between the exhaust collar and the existing cold air return. The exhaust hose should be attached to the return air duct, close to the furnace. The ideal location is low on the return air boot pointing at the furnace. To prevent air shear inside the duct, it is recommended that you install a deflector inside the boot, so the discharged air is deflected down into the boot. When running the hose, make sure that there are no kinks or sharp bends that will impede the air flow from the unit. Secure and seal the hose and connections to prevent air leakage.
  6. It is important to maintain some distance between the intake and the exhaust openings in the return air duct. Failure to do this may result in short cycling between the intake and the clean air discharge. It is recommended you leave 10 feet between the intake and the exhaust; however, as little as 6 feet will work effectively. If the distance is smaller than 6 feet, it is important that an air deflector is installed in the duct.
  7. If outside air is introduced into the return air duct, either through a HRV (Heat Recovery Ventilator) or direct, it should be added to the system before the intake inlet to the Air Cleaner.
