A common approach involves utilizing air purifiers. These devices are designed to capture and remove airborne particles, including odors, through filters or ionization processes. Electrostatic precipitators and ozone generators are also employed for more potent odor removal.
Other methods include fogging, which disperses a deodorizing agent throughout an area, and encapsulation, where substances are applied to surfaces to trap and seal in odors. Thermal fogging, using heat to disperse odor-neutralizing agents, and hydroxyl generators, which produce hydroxyl radicals to attack odors, offer additional options for odor control.
However, it's important to note that the effectiveness of air purifiers depends on various factors, such as the type of odor, the size of the space, and the performance of the purifier itself. Some odors, such as those caused by smoke or spoiled food, may require more specialized methods for complete removal.
