Premium Glass Microfiber Air Filter Media China Suppliers and Factory
Our premium Glass Microfiber Air Filter Media is engineered from high-purity glass microfiber wool using an advanced wet-forming process. This ensures a uniform fiber distribution that delivers an exceptional balance of high dust-holding capacity and low air resistance. Designed for high-intensity environments, it serves as the ideal substrate for high-efficiency air filtration systems requiring rigorous purity standards.
To meet diverse industrial and commercial needs, our product range is categorized into three high-performance series: ASHRAE (F5-F9), HEPA (H10-H14), and ULPA (U15-U17). From residential air purifiers and pharmaceutical cleanrooms to semiconductor chip factories and nuclear exhaust equipment, our filter media provides the critical barrier necessary to maintain sterile and contaminant-free environments.

HEPA (H10-H14) filters are generally used for cleanrooms from 10,000 to 100,000 grade, while ULPA (U15-U17) filters offer higher efficiency (up to 99.9999%) and are used in ultra-clean environments like chip factories and grade 1-10 cleanrooms.
It is widely used in pharmaceutical processing, microelectronic component assembly, photographic film manufacturing, nuclear exhaust systems, and high-grade household air purifiers.
The wet-forming method ensures that the glass microfiber wool is well-distributed, which leads to a more uniform pore structure, higher dust-holding capacity, and lower air resistance compared to dry-forming methods.
Yes, our glass microfiber media is an ideal material for paint spray booth filters, providing the necessary intensity and efficiency to capture paint particulates effectively.
The air resistance for the ASHRAE series (F6-F9) ranges from approximately 20 Pa to 55 Pa at a face velocity of 5.3cm/s, depending on the specific grade selected.
Yes, with a tensile strength of 1200 N/M (MD), the material is designed for high intensity, ensuring it does not tear or deform under the pressure of industrial air compressors or turbine intakes.
