Introduction to Fiberglass Air Filter Paper
The Fiberglass Air Filter Paper is a revolutionary material engineered to meet the demands of modern air filtration systems. Manufactured using glass microfiber wool, this filter media is produced through a wet-forming process that ensures uniform fiber distribution, high dust-hold capacity, and low air resistance. These characteristics make it an ideal choice for a wide range of applications, from residential HVAC systems to industrial cleanrooms.

Key Features and Advantages
The Fiberglass Air Filter Paper stands out due to its exceptional features, including:
- Superior Dust-Hold Capacity: The evenly distributed fibers allow the filter to trap more particulate matter without increasing airflow resistance.
- Low Air Resistance: Despite its high efficiency, the paper maintains minimal pressure drop, ensuring energy-efficient operation.
- High Mechanical Strength: The robust structure of the glass microfiber ensures durability, even under demanding conditions.
- Customizable Efficiency Levels: Available in ASHRAE, HEPA, and ULPA grades, the product caters to diverse filtration needs.

Technical Specifications
The Fiberglass Air Filter Paper is available in three primary series: ASHRAE, HEPA, and ULPA, each tailored for specific applications. Below is a detailed table of its technical parameters:
