Fiberglass air filter paper is a critical component in modern air purification systems, offering exceptional efficiency and durability. Manufactured by Hebei Fangyu Filters Material Technology Co., Ltd., this product leverages advanced glass microfiber technology to deliver high-performance filtration across a wide range of applications. From residential HVAC systems to industrial cleanrooms, fiberglass air filter paper plays a vital role in maintaining air quality and protecting sensitive equipment.
Understanding the Technology Behind Fiberglass Air Filter Paper
Fiberglass air filter paper is produced using a wet-forming method, which ensures uniform fiber distribution and optimal performance. The material is composed of fine glass microfibers, creating a dense yet low-resistance structure that effectively captures airborne particles. This technology allows the filter to balance high dust-hold capacity with minimal airflow resistance, making it ideal for both commercial and industrial applications.
The key characteristics of fiberglass air filter paper include:
- High Dust-Hold Capacity: The unique fiber structure enables the filter to trap a large volume of particulate matter without clogging quickly.
- Low Air Resistance: The design minimizes pressure drop, ensuring energy-efficient operation of air filtration systems.
- High Strength: The fibers are engineered to withstand mechanical stress, maintaining structural integrity even under demanding conditions.


Product Classification and Filter Efficiency
Fiberglass air filter paper is categorized into three main series based on filter efficiency: ASHRAE, HEPA, and ULPA. Each series is designed to meet specific filtration requirements, as outlined below:
ASHRAE Series (F5–F9)
The ASHRAE series is suitable for general-purpose applications, including residential and commercial air conditioning systems. These filters are ideal for capturing larger particles such as dust, pollen, and mold spores. Key features include:
- Filter Grades: F5, F6, F7, F8, F9
- Efficiency: 60%–95%
- Applications: Gas turbine air intakes, air compressors, and standard HVAC systems.
HEPA Series (H10–H14)
HEPA (High-Efficiency Particulate Air) filters are designed to capture 99.97% or more of airborne particles as small as 0.3 microns. These filters are commonly used in environments requiring high air purity, such as:
- Filter Grades: H10, H11, H12, H13, H14
- Efficiency: 94%–99.995%
- Applications: Cleanrooms, pharmaceutical processing, and high-end vacuum cleaners.
ULPA Series (U15–U17)
ULPA (Ultra-Low Penetration Air) filters offer the highest level of filtration, with efficiency rates exceeding 99.9999%. These filters are essential in ultra-clean environments such as:
- Filter Grades: U15, U16, U17
- Efficiency: 99.999%–99.9999%
- Applications: Semiconductor manufacturing, biotechnology labs, and nuclear facilities.
