Air Filter Media: Comprehensive Guide to Professional-Grade Filtration Material

Core Advantages & Technical Features

1.1 Multi-Layer Composite Structure

Triple-layer composite technology (MERV 12-14 efficiency):

• ‌Outer Polyester Layer‌: Captures large particles >5μm (pollen, dust)
• ‌Melt-Blown Mid-Layer‌: Traps 1-5μm particles (PM2.5, bacteria)
• ‌Electret Charge Layer‌: Adsorbs 0.3-1μm particles via electrostatic field (viruses, smoke)

1.2 Industry-Leading Performance

Five Application Solutions

2.1 Industrial Applications

• ‌Semiconductor Cleanrooms‌: Anti-static version (surface resistance 10⁶-10⁹Ω)
• ‌Food Processing‌: FDA-compliant food-grade material
• ‌Pharmaceuticals‌: GMP-certified antimicrobial coating

2.2 Commercial/Residential Use

• ‌HVAC Systems‌: Custom sizes (5-100mm thickness)
• ‌Air Purifiers‌: Compatible with major brands (IQAir, Blueair)
• ‌Ventilation Systems‌: Low air resistance design

Buyer's Guide & FAQs

3.1 Four-Step Selection Method

1. ‌Measure Dimensions‌: Precise frame measurements (<2mm tolerance)
2. ‌Check Ratings‌: EN779:2012/F9 or higher certification
3. ‌Calculate Airflow‌: Formula: Area × Velocity × 0.8
4. ‌Verify Material‌: Medical-grade? Choose PTFE membrane

3.2 Common Questions

‌Q: Can filter media be reused after washing?‌
A: Only pre-filters (≤G4 rating). Washing damages mid/high-efficiency fibers - replace regularly.

‌Q: When to replace filter media?‌
A: Replace immediately if:

• Airflow drops >30%
• Visible darkening of media
• PM2.5 penetration >5% (per monitors)

Maintenance Guidelines

• ‌Monthly Check‌: Measure light transmittance with lux meter (new media baseline: 85%)
• ‌Quarterly Cleaning‌: Reverse compressed air purge (≤0.3MPa pressure)
• ‌Storage‌: Protect from light/moisture at 15-25℃, ≤60% humidity
