High Dust Holding Capacity White Polyester Air Pre Filter Material Hepa Filter Cloth For G2/G3/G4/F5
Pre-filter media is an essential component in HVAC systems, designed to capture larger airborne particles such as dust, pollen, lint, and hair before they reach the main filter. This preliminary filtration helps to extend the life of the primary filter, maintain optimal airflow, and improve the overall efficiency of the HVAC system.
1. Designed to capture larger airborne particles such as dust, pollen, lint, and hair.
2. Made from robust materials like synthetic fibers, metal mesh, or pleated paper.
3. Cost-effective and environmentally friendly by reducing waste.

Air pre-filter materials are designed to capture larger particles such as dust, debris, and larger contaminants before the air enters the main filtration system. These pre-filters help extend the lifespan of finer, more specialized filters downstream by preventing premature clogging. Common materials used for air pre-filters include:
Made from imported polyester fiber filter material, the fibers have varying melting points arranged in a three-dimensional, non-oriented structure. The manufacturing process includes needle punching, bonding, and hot melting. The resulting product features tightly bonded fibers, fracture resistance, detachment resistance, corrosion resistance, wear resistance, and elastic recovery.

● Grade: G1-G4
● Frame Options: Cardboard, aluminum and galvanized steel
● Features low resistance, high dust capacity, washability, and long service life
● Offers good flame retardancy with a fire resistance rating of UL2
APPLICATIONS
Air pre-filter materials are versatile and essential for various applications. They are widely used in HVAC systems, industrial air filtration, and cleanrooms to capture larger particles and extend the life of main filters. In the automotive industry, they improve engine performance and cabin air quality. Commercial kitchens use them to trap grease and smoke, while medical facilities rely on them to maintain sterile environments. Agricultural and livestock facilities utilize them to protect both livestock and equipment. They are also crucial in airports and public transport for enhancing passenger air quality, in data centers to safeguard sensitive electronics, and in waste management facilities to control odors and particulate
