Fiberglass air filter paper has become a cornerstone in modern air purification systems, offering exceptional efficiency and durability. Manufactured by Hebei Fangyu Filters Material Technology Co., Ltd., this product is engineered to meet the rigorous demands of both industrial and residential applications. This article explores the technical specifications, applications, and advantages of fiberglass air filter paper, while also highlighting the company’s commitment to quality and innovation.
Product Overview and Key Features
Fiberglass air filter paper is produced using a wet-forming method, resulting in a material with well-distributed fibers, high dust-hold capacity, low resistance, and high tensile strength. These properties make it an ideal choice for air filtration systems where efficiency and longevity are critical. The product is categorized into three main series based on filter efficiency: ASHRAE, HEPA (High-Efficiency Particulate Air), and ULPA (Ultra-Low Penetration Air). Each series is designed to address specific filtration needs, from basic air conditioning to ultra-clean environments in semiconductor manufacturing.

Key Features:
- High Dust-Hold Capacity: Ensures longer filter life and reduced maintenance frequency.
- Low Air Resistance: Enhances energy efficiency by minimizing pressure drop across the filter.
- Exceptional Tensile Strength: Provides structural integrity, even under demanding conditions.
- Customizable Grades: Available in ASHRAE (F5–F9), HEPA (H10–H14), and ULPA (U15–U17) to suit diverse applications.
Technical Specifications and Performance Metrics
The following table provides a detailed overview of the technical specifications for each filter series:
| Classification | Grade | Efficiency (%) | Basic Weight (g/m²) | Thickness (mm) @100kPa | Air Resistance (Pa) @5.3cm/s | Tensile Strength (N/m) MD | Stiffness (mg) MD |
|---|---|---|---|---|---|---|---|
| ASHRAE | FY-F9 | 95 | 70 | 0.34 | 55±10 | 1200 | 1200 |
| FY-F8 | 90 | 70 | 0.34 | 35±5 | 1200 | 1200 | |
| FY-F7 | 80 | 70 | 0.34 | 33±5 | 1200 | 1200 | |
| FY-F6 | 60 | 70 | 0.33 | 20±5 | 1200 | 1200 | |
| HEPA | FY-H14 | 99.995 | 70 | 0.34 | 340±20 | 1200 | 1000 |
| FY-H13 | 99.97 | 70 | 0.34 | 290±20 | 1200 | 1000 | |
| FY-H12 | 99.8 | 70 | 0.34 | 250±20 | 1200 | 1000 | |
| FY-H11 | 98 | 70 | 0.34 | 120±20 | 1200 | 1000 | |
| FY-H10 | 94 | 70 | 0.34 | 80±15 | 1200 | 1000 | |
| ULPA | FY-U17 | 99.9999 | 73 | 0.37 | 500±20 | 1200 | 1000 |
| FY-U16 | 99.9999 | 73 | 0.37 | 440±20 | 1200 | 1000 | |
| FY-U15 | 99.999 | 73 | 0.37 | 390±20 | 1200 | 1000 |
These specifications highlight the product’s versatility, with HEPA and ULPA filters achieving ultra-high efficiency in removing particles as small as 0.1 microns. The ASHRAE series, on the other hand, is ideal for general-purpose air conditioning systems and industrial applications requiring moderate filtration.

Applications Across Industries
Fiberglass air filter paper is used in a wide range of applications, including:
- Home Air Conditioners: Enhances indoor air quality by trapping dust, pollen, and other airborne particles.
- Room Air Purifiers: Provides effective filtration for households and offices, ensuring cleaner air.
- Vacuum Exhaust Filters: Captures fine dust and debris, prolonging the lifespan of vacuum systems.
- HEPA and ULPA Filters: Critical for cleanrooms in semiconductor manufacturing, pharmaceuticals, and microelectronics.
- Photographic Film Manufacturing: Maintains a dust-free environment to prevent contamination.
- Pharmaceutical Processing: Ensures compliance with stringent GMP (Good Manufacturing Practice) standards.
- Paint Spray Booths: Prevents particle contamination during coating processes.
For high-grade applications, such as chip factories and 100,000-grade cleanrooms, ULPA filters are the preferred choice due to their 99.9999% efficiency in capturing ultra-fine particles. HEPA filters are commonly used in nuclear air exhaust systems, high-end vacuum cleaners, and medical-grade air purifiers.
