A fogging machine creates a fine mist or fog of liquid (like disinfectant, insecticide, or scented fluid) to quickly and evenly treat large areas for sanitization, pest control, mold, or odor elimination, reaching surfaces and air where traditional cleaning misses, ideal for homes, hospitals, cars, and businesses. These machines, including ULV (Ultra-Low Volume) and thermal types, use pressure or heat to atomize solutions into tiny droplets for thorough coverage and are available in portable or larger industrial models.
