Introduction to Fiberglass Air Filter Paper
The Fiberglass Air Filter Paper is a high-performance material engineered to meet the demands of modern air filtration systems. Crafted from glass microfiber wool through a wet-forming process, this filter media is designed to deliver exceptional dust-hold capacity, low air resistance, and robust mechanical strength. Its versatility makes it a preferred choice across diverse industries, from residential HVAC systems to advanced cleanroom environments. Developed by Hebei Fangyu Filters Material Technology Co., Ltd., the product adheres to international standards such as NIST guidelines, ensuring reliability and precision in performance.

Key Features and Advantages
The Fiberglass Air Filter Paper stands out due to its unique combination of properties:
- Uniform Fiber Distribution: The wet-forming method ensures even fiber alignment, optimizing filtration efficiency and durability.
- High Dust-Hold Capacity: The material effectively captures and retains particles, reducing the frequency of replacements.
- Low Air Resistance: Designed to minimize pressure drop, it enhances energy efficiency in ventilation systems.
- Excellent Mechanical Strength: The fibers are reinforced to withstand high airflow and mechanical stress, ensuring longevity.
These features make it ideal for applications requiring consistent air quality, such as HEPA filter paper and ULPA filters, which demand precision and reliability.

Technical Specifications
The Fiberglass Air Filter Paper is categorized into three series—ASHRAE, HEPA, and ULPA—each tailored for specific filtration needs. Below is a detailed table of its technical parameters:
| 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 |
| 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 |
These specifications highlight the product’s adaptability to varying filtration requirements, from standard HVAC systems to ultra-clean environments.
