Fiberglass Air Filter Paper is a cutting-edge filtration material designed to deliver superior air purification across diverse industries. Manufactured by Hebei Fangyu Filters Material Technology Co., Ltd., this product combines advanced engineering with high-performance characteristics to meet the demands of modern air quality standards. Whether for residential use or industrial applications, fiberglass filter paper offers a reliable solution for maintaining clean and safe environments.

Key Features of Fiberglass Air Filter Paper
Fiberglass Air Filter Paper is engineered with glass microfiber wool using a wet-forming method, ensuring a uniform fiber distribution. This process results in a material with exceptional dust-hold capacity, low resistance, and high strength. These properties make it ideal for use in various filtration systems, including HEPA and ULPA filters.
One of the standout features of this product is its ability to maintain low airflow resistance while efficiently capturing airborne particles. This balance between efficiency and performance is critical for applications where energy consumption and air quality are paramount. Additionally, the high tensile strength of the paper ensures durability, even under demanding conditions.
Technical Specifications and Performance
The Fiberglass Air Filter Paper is categorized into three main series based on filter efficiency: ASHRAE, HEPA, and ULPA. Each series is designed to meet specific filtration requirements, making it suitable for a wide range of applications.

The Fiberglass Air Filter Paper is tested according to EN779/ISO16890 standards, ensuring compliance with international quality benchmarks. These specifications highlight its ability to capture particles as small as 0.3 microns, making it suitable for applications requiring high-purity air environments.
Applications Across Industries
Fiberglass Air Filter Paper is widely used in both residential and industrial settings. Its versatility allows it to be integrated into home air conditioners, room air purifiers, and vacuum exhaust filters. In industrial environments, it is a critical component in HEPA filters, ULPA filters, and photographic film manufacturing processes.
For microelectronic component manufacturing and assembly, the paper’s high efficiency ensures contamination-free environments. In pharmaceutical processing, it helps maintain sterile conditions, while paint spray booths benefit from its ability to capture fine particles, ensuring high-quality finishes.
The ASHRAE series is ideal for ordinary air-conditioning systems, gas turbine air intakes, and air compressors. The HEPA series is used in 10,000 to 100,000-grade cleanrooms and nuclear air exhaust equipment, while the ULPA series is essential for chip factories and 100, 10, or even 1-grade cleanrooms.

Advantages of Fiberglass Air Filter Paper
One of the primary advantages of Fiberglass Air Filter Paper is its high dust-hold capacity, which reduces the frequency of filter replacements. This not only saves costs but also minimizes downtime in industrial operations. Its low resistance ensures that airflow is maintained at optimal levels, improving the efficiency of HVAC systems.
The high strength of the paper ensures it can withstand mechanical stress, making it suitable for use in high-velocity air systems. Additionally, its uniform fiber distribution enhances filtration efficiency, capturing particles more effectively than traditional materials.
Compared to other filtration media, Fiberglass Air Filter Paper offers a cost-effective solution without compromising on performance. Its ability to meet ISO and EN standards makes it a preferred choice for industries requiring strict air quality control.
