Fiberglass Air Filter Paper is a critical component in modern air purification systems, offering exceptional performance in diverse applications. Manufactured by Hebei Fangyu Filters Material Technology Co., Ltd., this product leverages advanced glass microfiber technology to deliver high dust-hold capacity, low resistance, and robust mechanical strength. This article explores the features, advantages, technical specifications, and real-world applications of this versatile filtration material, supported by authoritative references from the National Institute of Standards and Technology (NIST).
Product Features and Advantages
The Glass Microfiber Air Filter Media is produced using a wet-forming method, ensuring uniform fiber distribution and optimal performance. Key features include:
- High Dust-Hold Capacity: The material effectively captures and retains particulate matter, reducing the frequency of filter replacements.
- Low Air Resistance: Designed to maintain airflow efficiency while maximizing filtration effectiveness.
- High Mechanical Strength: Enhanced durability ensures the filter can withstand demanding operating conditions.
- Customizable Efficiency Levels: Available in ASHRAE, HEPA, and ULPA classifications to meet specific application requirements.

These attributes make Fiberglass Air Filter Paper an ideal choice for industries requiring precise air quality control, such as pharmaceuticals, semiconductor manufacturing, and HVAC systems. According to NIST research on filtration standards, the uniform fiber structure of such materials significantly enhances their ability to capture airborne particles [1]. This aligns with the EN779/ISO16890 test standards referenced in the product specifications, ensuring compliance with global quality benchmarks.
Technical Specifications
| Classification | Grade | Efficiency (%) | Basic Weight (g/m²) | Thickness (mm) | Air Resistance (Pa) | Tensile Strength (N/m) | Stiffness (mg) |
|---|---|---|---|---|---|---|---|
| ASHRAE | FY-F9 | 95 | 70 | 0.34 | 55±10 | 1200 | 1200 |
| ASHRAE | FY-F8 | 90 | 70 | 0.34 | 35±5 | 1200 | 1200 |
| HEPA | FY-H14 | 99.995 | 70 | 0.34 | 340±20 | 1200 | 1000 |
| ULPA | FY-U17 | 99.9999 | 73 | 0.37 | 500±20 | 1200 | 1000 |
The table above highlights the varied performance parameters of Fiberglass Air Filter Paper across different classifications. For instance, ULPA-grade filters (e.g., FY-U17) achieve 99.9999% efficiency, making them suitable for cleanrooms in semiconductor manufacturing [2]. In contrast, ASHRAE-grade filters (e.g., FY-F9) are ideal for residential HVAC systems due to their balance of cost and performance.
Application Scenarios
The versatility of Fiberglass Air Filter Paper is evident in its wide range of applications, including:
- Home Air Conditioners: ASHRAE-grade filters (F6–F9) provide efficient air purification for residential environments.
- HEPA Filters: Used in high-grade vacuum cleaners, air purifiers, and medical equipment to capture submicron particles.
- Industrial Cleanrooms: ULPA-grade filters (U15–U17) are essential for pharmaceutical processing and microelectronic component manufacturing.
- Photographic Film Manufacturing: Ensures contamination-free environments during sensitive production processes.
- Paint Spray Booths: Reduces airborne particles to maintain paint quality and worker safety.

According to NIST’s guidelines on air filtration in cleanrooms, the particle retention capacity of such filters is critical for maintaining ISO Class 1–100 environments [3]. This underscores the importance of Fiberglass Air Filter Paper in industries where contamination control is paramount.
