Odor Control Systems are designed to reduce or completely eliminate all traces of unwanted scents within an air supply. Popular in industrial, commercial and residential applications, these systems neutralize malodors, making them unavailable for olfactory senses to pick up, thus improving air quality. Though not all odorous emissions are toxic or even physically harmful, odors that are purely unpleasant can have a negative impact on the quality of life and productivity of an area or process. In unpleasant odor situations, it is essential that air pollution control equipment come equipped with odor control systems. These systems often mask the disagreeable smell with a stronger more pleasant scent, though this is a temporary solution. Alternatively, odor controls may neutralize them by absorbing them with specially configured powders, sprays, or filters. The latter and more permanent solution is often preferable, particularly in industrial atmospheres where smelly gasses can accumulate in large quantities.
