Is higher filtration precision always better for cartridges?

No. Excessively high precision means smaller media pores and greatly increased airflow resistance, which can reduce equipment suction, clog cartridges quickly, and increase cleaning frequency and energy consumption; too low a precision fails to capture fine dust and causes excessive emissions. Match precision to the conditions: standard precision for ordinary industrial dust; for strict emission requirements and fine dust, membrane high-precision cartridges are recommended.
