Fiberglass air filter paper has become a cornerstone in modern air purification systems, offering exceptional performance in diverse environments. Manufactured using glass microfiber wool through a wet-forming method, this material is engineered to provide high dust-hold capacity, low air resistance, and superior mechanical strength. Its versatility makes it ideal for applications ranging from household air conditioners to critical industrial environments like semiconductor manufacturing. This article delves into the technical specifications, application scenarios, and company background of this advanced filtration solution.
Product Overview: Glass Microfiber Air Filter Media
The glass microfiber air filter media is a high-performance material designed to capture airborne particles efficiently. Its unique structure, characterized by well-distributed fibers, ensures uniform airflow while maximizing particulate retention. The product is categorized into three main series based on filtration efficiency: ASHRAE, HEPA, and ULPA. Each series is tailored to meet specific industry requirements, from general ventilation to ultra-cleanroom environments.

Key Features:
- High Dust-Hold Capacity: Efficiently captures and retains particulates without clogging.
- Low Air Resistance: Ensures minimal pressure drop, reducing energy consumption.
- High Mechanical Strength: Maintains structural integrity under demanding conditions.
- Customizable Grades: Available in F6-F9 (ASHRAE), H10-H14 (HEPA), and U15-U17 (ULPA) for diverse applications.
Technical Specifications: Detailed Performance Metrics
The following table outlines the technical parameters of the fiberglass air filter paper across different series:

The data underscores the product’s adaptability to specific filtration needs, with ULPA grades achieving 99.9999% efficiency for ultra-clean environments like semiconductor fabrication. The HEPA series is ideal for 10,000–100,000-grade cleanrooms, while ASHRAE filters cater to general ventilation systems and industrial air intake applications.
Applications: Versatile Use Across Industries
The fiberglass air filter paper is employed in a wide array of sectors, including:
- Home Air Conditioning: Enhances indoor air quality by removing dust, pollen, and allergens.
- Industrial Air Purifiers: Critical in pharmaceutical processing, microelectronic manufacturing, and paint spray booths.
- HEPA and ULPA Filters: Used in nuclear air exhaust systems, high-grade vacuum cleaners, and medical masks.
- Photographic Film Manufacturing: Ensures contamination-free environments for sensitive processes.

For chip manufacturing facilities, ULPA-grade filters are indispensable, as they maintain 100, 10, or even 1-grade cleanrooms. In pharmaceutical applications, the material’s low particle shedding and chemical resistance ensure compliance with GMP (Good Manufacturing Practice) standards.
