| Performance Metric | Standard Fiber Media | Our Glass Microfiber |
|---|---|---|
| Filtration Efficiency | Basic/Moderate | Up to 99.9999% (ULPA) |
| Energy Cost (Resistance) | Higher Pressure Drop | Optimized Low Resistance |
| Service Life | Frequent Replacement | Extended High Dust Capacity |
| Cleanroom Grade | General Purpose | Grade 1 to 100,000 |
| Material Stability | Variable | High Intensity & Stiffness |
HEPA (H10-H14) typically captures particles down to 0.3 microns with 99.97% efficiency, whereas ULPA (U15-U17) is designed for ultra-clean environments like chip factories, capturing smaller particles with efficiency up to 99.9999%.
For ordinary air-conditioning systems, gas turbine air intakes, and air compressors, the ASHRAE series (F5-F9) is recommended as it provides effective filtration with very low air resistance.
The wet-forming method ensures that the glass fibers are well-distributed and intertwined uniformly. This creates a more consistent pore structure, which increases the dust-holding capacity and prevents air bypass.
Yes, our HEPA and ULPA series are specifically designed for pharmaceutical processing and cleanrooms (Grade 10,000 to 100) to ensure an aseptic environment.
Our fiberglass air filter paper maintains a high tensile strength of ≥ 1200 N/M in the Machine Direction (MD), ensuring stability under high-velocity air currents.
Absolutely. Due to its high efficiency and durability, it is widely used in paint spray booth filter media and ceiling filters to remove airborne contaminants.
