Box Type Fine Filters are engineered for high-efficiency particulate removal in HVAC and controlled environment systems. With a sturdy box-shaped frame, they offer excellent rigidity and stability, even under high airflow conditions. These filters effectively capture fine dust, pollen, mold spores, and other airborne contaminants, improving air quality and protecting downstream equipment or sensitive processes.

Constructed from durable galvanized steel, aluminum, or high-impact plastic frames, they incorporate synthetic or fiberglass media to achieve various efficiency ratings. Optimized pleat spacing and media depth provide high dust-holding capacity with low pressure drop. Ideal for medium-to-high efficiency applications, they ensure reliable performance and consistent airflow.
