Glass Fiber Filter Paper, crafted from glass fibers using a wet-laid process, offers uniform fiber distribution, high dust holding capacity, low resistance, and strong structural integrity. These qualities make it an ideal air filtration material. The filter paper comes in three series based on filtration efficiency:

Medium Efficiency (ASHRAE): Suitable for general air conditioning systems, gas turbines, and compressors.
Sub-High Efficiency (HEPA): Ideal for cleanrooms from Class 10,000 to 100,000, exhaust systems in nuclear power stations, high-end household vacuum cleaners, air purifiers, and gas masks.
Ultra-High Efficiency (ULPA): Used in semiconductor factories and cleanrooms at Class 100, Class 10, and Class 1 levels.

Features

High Purity: Composed entirely of borosilicate glass, ensuring minimal extractable organics that could contaminate samples.
Heat Resistant: Withstands high temperatures, maintaining integrity and performance even under thermal stress.
Efficient Particle Retention: Captures fine particulates effectively due to its microfiber construction, making it suitable for precision filtration tasks.

Material Composition

The filter paper consists of borosilicate glass microfibers, providing a stable and inert filtration medium. This is ideal for sensitive analytical procedures.

In summary, Glass Fiber Filter Paper, with its high dust holding capacity, low resistance, and strong structural integrity, is perfect for various air filtration applications. Its different efficiency levels cater to a wide range of needs, from general air conditioning systems to high-end cleanrooms.
