What is the typical application of thermal fogging in odor control?

Thermal fogging is primarily used in odor control for modification rather than elimination or masking. The process involves using a machine that heats a solution containing odor counteractants to create a fog, which is then dispersed into the contaminated space. This fog can penetrate porous materials and reach areas that may be inaccessible for other methods. As it interacts with the source of the odor, the constituents in the fog chemically modify the odor molecules, making them less detectable or altering their characteristics.

Modification is a more effective approach in situations where odors are deeply embedded in materials or environments, as it changes the odor's composition rather than simply covering it up or attempting to dilute it. This enhances the overall efficacy of odor control in challenging situations, making it a preferred method in many restoration and remediation scenarios.
