Product Overview: The Science Behind Fiberglass Air Filter Paper
Fiberglass air filter paper is a high-performance filtration medium crafted from glass microfiber wool using a wet-forming method. This process ensures a uniform distribution of fibers, resulting in a material that balances high dust-hold capacity, low air resistance, and exceptional mechanical strength. These characteristics make it an ideal choice for applications requiring precise particle capture and long-term durability.
The product is categorized into three primary series based on filtration efficiency: ASHRAE, HEPA, and ULPA, each tailored for specific air quality requirements. The HEPA filter paper for sale and fiberglass filter paper variants are particularly renowned for their ability to capture submicron particles, making them indispensable in cleanroom environments, medical facilities, and advanced HVAC systems.
Technical Specifications: Precision-Engineered Parameters
The technical performance of fiberglass air filter paper is defined by a comprehensive set of specifications, ensuring compatibility with a wide range of filtration systems. Below is a detailed table outlining key parameters for each classification:
| 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 | |

| 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 reflect adherence to international standards such as EN779/ISO16890, which ensure consistent performance across global markets. The high tensile strength and low stiffness values demonstrate the material’s ability to withstand mechanical stress while maintaining flexibility, crucial for complex filter designs.
Applications: Versatile Solutions for Critical Environments
Fiberglass air filter paper is engineered to meet the demands of both industrial and consumer applications. Its versatility is evident in the following use cases:
- Residential HVAC Systems: ASHRAE-grade filters (F6-F9) are ideal for standard air conditioning systems, ensuring improved indoor air quality while maintaining energy efficiency.
- Commercial Air Purifiers: HEPA filters (H10-H14) are widely used in high-end vacuum cleaners, air purifiers, and mask manufacturing, capturing 99.97% to 99.995% of airborne particles.
- Industrial Cleanrooms: ULPA filters (U15-U17) are essential in semiconductor manufacturing, pharmaceutical processing, and biotechnology labs, where particle counts must be maintained at 100,000 to 1-grade cleanliness levels.
- Specialized Equipment: Applications include gas turbine air intakes, paint spray booths, and nuclear facility exhaust systems, where reliability and performance are non-negotiable.
According to the National Institute of Standards and Technology (NIST), “Standardized filtration testing protocols are critical for ensuring the safety and efficacy of air purification systems in both industrial and residential settings” (NIST, 2025). This aligns with the rigorous testing framework employed by Hebei Fangyu Filters Material Technology Co., Ltd.
