The removal of gaseous pollutants ( odors ) is often accomplished by using a masking agent sprayed into the room or area with the odor. If the odor is temporary or infrequent then the aerosol spray deodorizers will usually meet the task. If, however, the odor is from a continuous source and is strong enough or dangerous to breathe then commercial grade carbon media filters will be required.
The use of expanded carbon ( charcoal) for the reduction/removal of airborne gaseous pollutants has been around for over 100 years. These carbon media packs ( usually 1 inch to 4 inches in depth) can be very effective at removing these strong, continuous odors and the carbon can be combined with other materials to catalyze some pollutants that are not removed by just carbon alone.
Pure Air Systems, has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems, since 1985. These metal framed units incorporate the newer variable speed motors and the air flows range from a low of 50 CFM up to 2,000 CFM. PAS offers a wide range of sizes and configurations to fit any specific need. Some of the large units can hold up to 80 lbs of carbon media or applications where high concentrations of gaseous pollutants are present.
