Combinatorial Air Filter(39804)

Syracuse University


Most buildings use air filters in ductwork to protect occupants and heating and cooling equipment from particles in outdoor air and recirculated indoor air. If a building needs odor control and a high efficiency particle air filter, two separate filters are needed - one to capture particles and another containing an activated media for absorbing gaseous pollutants. Syracuse University (SU) believes energy savings could be achieved by developing a single filter made of synthetic polyester fibers impregnated with an activated media. The proposed single filter could have a lower pressure drop than two separate filters providing the same functions and may reduce outdoor air requirements, and hence reduce energy consumption for heating, ventilating, and air-conditioning (HVAC).

Project Description

SU will develop a single-stage air filtration technology for particle and gaseous pollutant removal. The work will determine the proper mixture ratio of hybrid sorbent media according to the pollutants in the air streams. The attachment method and size of activated sorbent powders to be applied on the fiber of a particle filter will be studied. SU will evaluate the effects of operational environmental conditions (including temperature, humidity, and airflow conditions) on the combinatorial filter removal efficiency and service life.


Energy savings of 10% of a building’s heating and cooling energy usage could be achieved with the proposed filter.
