In-Duct Air Cleaners
In-duct air cleaners install into ducted HVAC systems to clean the air in all rooms that are connected to the HVAC system. Also called whole-house air cleaners or air purifiers, they reduce airborne contaminants to help improve indoor air quality and neutralize odors in schools, offices, and other occupied spaces. These units require professional installation, and they only clean the air when the HVAC system is running. In-duct air cleaners rely on the airflow of the HVAC system to circulate the air, and they use one or more air cleaning methods to remove contaminants from the air that passes through them.
Media In-Duct Air Cleaners
The filter media in these air cleaners neutralizes odors and traps airborne particles as air passes through the air cleaners. Also known as furnace air cleaners, media air cleaners help capture airborne particles released by the building's furnace. These air cleaners install into the return air duct of a forced-air HVAC system, and the system must be running to move air through the air cleaners.

VOC- & Odor-Reducing PCO In-Duct Air Cleaners
These in-duct air cleaners use photocatalytic oxidation (PCO) filter media to neutralize volatile organic compounds (VOCs) and other gaseous pollutants in the air that moves through the air cleaners. They also have UV-C bulbs that reduce airborne viruses, mold, and bacteria. PCO in-duct air cleaners install into the main supply or return air duct of a forced-air HVAC system. They can operate continuously, but they require the HVAC system to be running to move air through the filters and past the bulbs. The cleaners can also be placed near the HVAC system's A-coil to prevent mold and bacteria from growing on the A-coil and maintain the efficiency of the system's air conditioning.
