A cabinet filter is typically installed within a cabinet or enclosure that houses heating, ventilation, and air conditioning (HVAC) systems or other air treatment equipment. The primary purpose of these filters is to clean the air that passes through them. They can be made from various materials, such as fiberglass, activated carbon, or HEPA (High-Efficiency Particulate Air) filters. The choice of filter material depends on the specific needs of the environment and the level of air purification required.

    How Cabinet Filters Work

    Cabinet filters function by using a combination of mechanical and electrostatic processes to capture airborne particles. As air is drawn into the HVAC system, it passes through the filter, where various contaminants are trapped. Larger particles such as dust and pet dander are captured by the filter’s fibers, while smaller particles, including pollen, mold spores, and bacteria, are removed through electrostatic attraction or adsorption.
