What are the core differences between cartridge and bag filtration? What are their respective advantages?

The core differences lie in media structure, filtration mode and application: 1) Cartridges use pleated media — large filtration area in a compact body, mainly surface filtration with thorough cleaning, suitable for dry, fine dust and confined working spaces; 2) Bags are cylindrical fabric media — mainly depth filtration, with good permeability and stronger temperature resistance, suitable for high-humidity, high-temperature and coarse dust conditions. Cartridge advantages: small footprint, high filtration precision and easy installation; bag advantages: adaptable to complex high-temperature conditions.
