Introduction to Fiberglass Air Filter Paper

Fiberglass air filter paper, specifically glass microfiber air filter media, represents a cutting-edge solution in air filtration technology. Manufactured using a wet-forming method, this material is characterized by its uniformly distributed fibers, high dust-hold capacity, low resistance, and exceptional strength. These properties make it an ideal choice for a wide range of applications, from residential HVAC systems to industrial cleanrooms. The product is categorized into three main series based on filtration efficiency: ASHRAE, HEPA, and ULPA.

The glass microfiber air filter media is engineered to balance high efficiency with minimal airflow resistance, ensuring optimal performance in both commercial and industrial settings. Its ability to capture a wide range of particulate matter, from large dust particles to submicron allergens, makes it a versatile solution for air purification.

Applications Across Industries

The versatility of fiberglass air filter paper is evident in its widespread use across multiple sectors. ASHRAE series filters are commonly employed in ordinary air-conditioning systems, gas turbine air intakes, and compressors. The HEPA filters, with their high efficiency, are essential in environments requiring stringent air quality control, such as pharmaceutical processing, semiconductor manufacturing, and high-end household vacuum cleaners. Meanwhile, ULPA filters are designed for ultra-clean environments like chip fabrication facilities and grade 100 or even grade 1 cleanrooms.

Additional applications include:

• Photographic film manufacturing
• Microelectronic component assembly
• Paint spray booths
• Air exhaust equipment for nuclear facilities
• High-grade air purifiers and masks
