Odor control for swine facilities has focussed on storage and the land application phases of manure handling. A third component, ventilation exhaust air, has received little attention. This research was targeted at reducing odor emitted from ventilation exhaust air by filtering odor carrying dust particles. The ultimate objective is to develop a system that could be implemented easily, has a low maintenance schedule, and is inexpensive to operate.
