Small local facilities such as gas stations, dry cleaners, and auto repair shops are widespread. They are found virtually everywhere, and their cumulative contribution to the overall volume of toxic emissions into the atmosphere is comparable to that of large industrial facilities. These small sources emit pollutants like benzene, perchloroethylene, and other hazardous air pollutants (HAPs). However, by installing a baghouse filter, air pollution can be effectively managed, ensuring cleaner air in the surrounding environment.
A significant amount of pollutants are produced by vehicles, road equipment, and specialized machinery. Their exhaust gases contain not only combustion products but also fuel vapors. Vehicles are major sources of nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC), which contribute to ground-level ozone formation and smog. The use of advanced filtration systems, such as baghouses in industrial settings, can help mitigate some of the indirect pollution caused by the manufacturing and maintenance of these vehicles and machinery.
