The choice of media, centrifugal, and electrostatic filters for mist and smoke removal is based on their specific design qualities and operational principles.

Media filters are effective at capturing various airborne particles, including mists, by providing a physical barrier that traps contaminants as air passes through. These filters utilize different materials that can address both particulate and gaseous pollution, offering versatile solutions for maintaining air quality in environments where mist and smoke are prevalent.

Centrifugal filters harness the principle of centrifugal force to separate particles from the air stream. As air enters the filter, it is subjected to rapid rotation, which causes heavier particles, such as smoke and mist droplets, to be thrown outward and collected in a designated area. This method is particularly useful for high-volume air applications, effectively handling larger amounts of polluted air without clogging.

Electrostatic filters utilize an electrical charge to attract and capture airborne particles, including smoke and mist. The charged particles adhere to a collecting surface, ensuring effective removal of fine particles that might otherwise pass through standard mechanical filters. This technology can improve filter efficiency and allow for the removal of sub-micron particles.

These filter types are well-suited for environments where mist and smoke are common, such as in industrial settings, kitchens, or areas
