1. Deep filtration with high dirt-holding capacity: The gradient pore structure captures impurities from outside to inside with pore sizes decreasing gradually. Its dust-holding space is far larger than that of surface filtration cartridges (e.g., filter membranes), resulting in a long service life.
Wound filter cartridges, also known as wire-wound filter cartridges or wire-wound honeycomb filter cartridges, are depth filtration elements made by precisely winding textile fiber yarns (such as polypropylene, absorbent cotton, glass fiber, etc.) onto a porous core as the filtration medium.

Application scenarios
1.Ventilation and air conditioning in office buildings, shopping malls, etc.: initial effect + medium effect combination to improve air quality;
2.Hospital and clean room: medium-effect bag type (F8–F9) with efficient terminals to ensure cleanliness requirements;
3.Industrial factory: First use initial protection and medium-effect filter dust to improve system reliability.
Select suggestions
1.Practical use:
Initial effect (G3/G4): suitable for pre-filtering;
Medium-effect (F5–F9): used for fine particle filtration, efficient pre-position;
2.Size matching: Common sizes include 595×595×381/600 mm, 3–10 bags;
3.Resistance control: Low initial resistance can save energy, and high-efficiency protection standards are selected for final resistance;
4.Filter material selection:
Polyester is more resistant to washing;
Glass fiber is more resistant to high temperatures;
5.Dust and replacement cycle:
Initial washable or replacement cycle 1–3 months;
The medium-effect usage cycle is about 6 months, and the replacement reaches final resistance based on the pressure drop.
