Introduction
Fiberglass air filter paper has emerged as a critical component in modern air purification systems, offering exceptional performance in various industrial, commercial, and residential settings. Manufactured from glass microfiber wool using a wet-forming process, this material is designed to provide high dust-hold capacity, low resistance, and superior strength. The product is categorized into three main series—ASHRAE, HEPA, and ULPA—each tailored to specific filtration efficiency requirements. This article delves into the product’s features, technical specifications, applications, and the company behind it, Hebei Fangyu Filters Material Technology Co., Ltd..
Product Features and Advantages
Material Composition and Manufacturing Process
The glass microfiber air filter media is produced through a wet-forming method, ensuring a uniform distribution of fibers. This process results in a material with high dust-hold capacity, low air resistance, and high mechanical strength. The unique structure of the glass microfibers allows the filter to capture a wide range of particulate matter, from large dust particles to sub-micron contaminants, without significantly impeding airflow.

Key Advantages
- High Efficiency: The product’s efficiency ranges from 60% to 99.9999%, depending on the series (ASHRAE, HEPA, ULPA).
- Low Air Resistance: Despite its high efficiency, the filter maintains low resistance, ensuring energy-efficient operation in HVAC systems.
- Robust Durability: With tensile strength up to 1200 N/m and stiffness of 1000 mg, the material withstands harsh operating conditions.
- Wide Application Scope: Suitable for residential, industrial, and cleanroom environments, it meets the demands of sectors such as pharmaceuticals, electronics, and automotive manufacturing.
