When selecting air filtration products, in addition to filtration efficiency, it is essential to comprehensively consider pressure drop and dust-holding capacity. Pressure drop refers to the pressure loss generated when air flows through the filter; a lower pressure drop indicates better ventilation performance and lower energy consumption. Dust-holding capacity, on the other hand, determines the service life of the filter. Generally, pleated or bag filters with a larger filtration area offer higher dust-holding capacities and relatively longer replacement cycles. Achieving a reasonable balance between these two indicators is crucial for ensuring the efficient operation of air purification systems.
