The Customized Mini-Pleat Hepa Filter Media Pack is a high-efficiency filtration solution engineered for ultra-fine particle removal. Made from high-purity glass fibers via a humid manufacturing process, its mini-pleat structure maximizes filtration area while saving space. Available in three core series—ASHRAE, HEPA, and ULPA—with efficiency ranging from 55% to 99.999%, it can be tailored to fit diverse equipment sizes. This makes it ideal for medical, aviation, and industrial scenarios where sterile or particle-free air is critical.
Classification | Grade | Efficiency (≥%) | Basic Weight (±5g/m²) | Thickness (±0.02mm) | Air Resistance (Pa @5.3cm/s) | Tensile Strength (±200N/M, MD) | Stiffness (≥mg, MD) |
ULPA | U15 | 99.999 | 73 | 0.33-0.35 | 390±20 | 1200 | 1000 |
HEPA | H14 | 99.995 | 70 | 0.33-0.35 | 340±20 | 1200 | 1000 |
HEPA | H13 | 99.97 | 76 | 0.33-0.35 | 290±20 | 1200 | 1058 |
HEPA | H12 | 99.8 | 70 | 0.33-0.35 | 250±20 | 1200 | 1000 |
HEPA | H11 | 98 | 70 | 0.33-0.35 | 120±20 | 1200 | 1000 |
HEPA | H10 | 94 | 70 | 0.33-0.35 | 80±15 | 1200 | 1000 |
ASHRAE | F9 | 85 | 70 | 0.33-0.35 | 55±10 | 1200 | 1200 |
ASHRAE | F8 | 55 | 74 | 0.33-0.35 | 35±5 | 800 | 850 |
With ULPA (99.999% efficiency) and HEPA (98%-99.995% efficiency) options, the media pack captures particles as small as 0.1 microns. Critical for sterile environments like medical cleanrooms.
Its mini-pleat design and flexible sizing (length, width, pleat density) fit compact equipment (e.g., FFUs, air purifiers, aviation cabins) without reducing filtration area.
Crafted from high-purity glass fibers, it offers high dirt holding capacity (extending service life) and strong tensile strength (up to 1200N/M), withstanding operational pressures without tearing.
Low air resistance (as low as 35±5Pa for F8 grade) minimizes energy use for HVAC or air purification systems, cutting long-term operational costs.
The Customized Mini-Pleat Hepa Filter Media Pack is perfect for:
Medical/pharmaceutical: Hospital cleanrooms, vaccine labs, and dental clinics (H14/U15 grades for sterility).
Aviation/aerospace: Aircraft cabin air systems and aerospace component manufacturing.
Industrial high-tech: Semiconductor factories, data centers, and electronic assembly lines (ULPA grades for particle-free air).
Residential/commercial: High-end air purifiers (H11/H12 grades) and museum HVAC systems (protecting artifacts from dust).
Specialized equipment: Clean benches, FFUs (Fan Filter Units), and laboratory fume hoods.
Install in a dust-free environment to avoid pre-contaminating glass fibers.
Use gaskets for airtight contact with equipment—leaks bypass the filter and reduce air quality.
Track pressure difference (PD) regularly; replace when PD exceeds the rated final resistance (e.g., 340Pa for H14 grade).
For medical/industrial use, replace every 6-12 months (or per system recommendations) to maintain sterility.
Store unused packs in a cool, dry area (15-25℃, 40%-60% RH) to prevent fiber degradation.
Avoid bending or compressing pleats—this damages the structure and reduces efficiency.
We customize size, pleat density, and grade (ASHRAE/HEPA/ULPA) to match your equipment’s needs. Share your system details for a tailored solution.
Yes. H11/H12 HEPA grades are ideal—they balance 98%-99.8% efficiency with low air resistance, suiting most residential purifiers.
While not designed for direct virus/bacteria removal, its high efficiency (e.g., H14 captures 99.995% of ≥0.3-micron particles) traps airborne carriers of viruses/bacteria, improving safety.
Mini-pleats boost filtration area in compact spaces, increasing dust holding capacity and service life while keeping air resistance low—unlike non-pleated filters.
Yes. It uses high-purity, non-toxic glass fibers that meet international safety standards for air filtration, making it safe for all applications.
