Many people confuse fumes with gases and vice versa leading to improper filtration parameters. Fumes are airborne particulates that can be captured in a physical media such as pre filters and HEPA filters while Gases must be adsorbed in various media such as Activated Carbon. The key to good adsorption of gases and odors is to choose the right media for the various gaseous compounds as each gas has its own molecular structure which may be adsorbed well by one media but not another.
Another key is to create proper dwell time for the gases to be in contact with the media. There are many things to consider when designing a system to insure this dwell time. Items such as airflow, volume of media, shape and size of the media, as well as the depth and width of the media bed all should be optimized to create the best adsorption and longest lasting filtration.
With more than 25 years of experience, IP Systems can be your guide to proper adsorption of Odors and Gases.

Gas adsorption is the process whereby gas molecules can stick to the surface of a solid particle. Activated carbon, for example, relies on adsorption to filter gaseous chemicals out of fumes. Our gas adsorption systems use activated carbon in the filter media in order to eliminate harmful gas vapors from the air that workers breathe.
One important factor for choosing filter media for gas adsorption and odor removal is to look at its activity level. Activity is defined as the ability of activated carbon to adsorb a gas or vapor. IP Systems USA recommends filter media with activated carbon activity levels of at least 60%.
Some odor control systems also use HEPA filters, as many odors are caused by particulate matter and cannot be trapped well with activated carbon. We provide systems that use both types of filter media in order to manage odors as effectively as possible.
But why use them in the first place? Having high odor levels in a workplace can harm workers’ morale, even if fume exposure is within permissible exposure limits. Nobody wants to work in a place with too much odor, and some gases are much smellier than others. Many odors produced by manufacturing processes have fishy, pungent, ammonia-like, or wholly disagreeable scents, and this can be a serious problem for employees.
Luckily, we have gas adsorption and odor control systems that will keep odors down to a much more acceptable level. Call us today to get pricing on our odor control systems!
