Product Key Features
Precise Efficiency & Low Resistance: Engineered to strike the perfect balance between high filtration efficiency and low pressure drop, ensuring optimal energy saving for HVAC systems.
Stable Structural Integrity: Thanks to high tensile strength and excellent stiffness, our paper undergoes high-speed automatic pleating effortlessly without shedding fibers, wrinkling, or breaking.
100% Reliable Lifespan: Unlike synthetic media that relies on temporary electrostatic charges, our fiberglass media utilizes purely physical interception. The filtration efficiency never decays over time.
High Dust-Holding Capacity: The intricate, multi-layered internal network traps particulates throughout the entire depth of the media, significantly extending the filter service life.
Material & Craftsmanship
Premium Raw Material: Formulated with 100% micro-glass fibers (ranging from 0.5 ~ 5um in diameter) blended with high-grade Eco-friendly binders, ensuring no chemical off-gassing.
Advanced Wet-Laid Technology: Manufactured via state-of-the-art wet-laid paper-making production lines. This guarantees exceptional uniformity in basis weight, thickness, and pore size distribution across the entire roll.
Excellent Environmental Tolerance: Naturally flame-retardant, highly resistant to corrosion, and capable of withstanding high temperatures up to 250°C – 300°C without structure deformation.
Strict Quality Control: Every batch undergoes rigorous automated testing (via TSI 8130 / Topas test rigs) for penatration, resistance, and mechanical properties before slitting and packaging.
Applications
Commercial & Industrial HVAC: The essential raw material for producing V-Bank filters, rigid cell filters, and pocket filters used in airports, shopping malls, and commercial buildings.
HEPA/ULPA Cleanroom Systems: Perfectly suited for H13, H14, and U15 Fan Filter Units (FFU) deployed in ultra-clean environments such as semiconductor fabrication, precision electronics, and pharmaceutical labs.
Automotive & Transport: High-performance media for automotive cabin air filters and heavy-duty engine intake filtration systems.
Specialized Industrial Filtration: Widely applied in high-temperature gas filtration, precision hydraulic oil cleaning, and industrial compressor oil-gas separators.
Competitive Comparison
| Key Metric / Feature | Our Premium Fiberglass Media | Conventional Synthetic Media (PP/Meltblown) |
| Efficiency Stability | 100% Stable. Relies purely on a permanent physical 3D structure; efficiency never decays over time. | Declines rapidly. Relies heavily on temporary electrostatic charge, which fades with humidity and usage. |
| Dust-Holding Capacity | Massive. Multi-layered depth filtration traps particulates throughout the thickness, extending filter lifespan. | Limited. Mainly surface loading, causing quick clogging and shorter replacement cycles. |
| Pleating & Processing | Optimized high tensile strength & stiffness for flawless running on high-speed automatic pleating machines. | High elasticity can cause stretching or deformation during rapid mechanical pleating. |
| Environmental Tolerance | Excellent. Naturally flame-retardant, chemical-resistant, and withstands temperatures up to 250°C – 300°C. | Poor thermal resistance; typically warps or degrades above 80°C. |
| Quality Sourcing Insurance | 100% Tested. Every batch is verified via TSI 8130 / Topas testing rigs before factory release. | Highly inconsistent quality from third-party trading middlemen. |

Frequently Asked Questions
Q1: What testing standards do your fiberglass filter papers comply with, and how do you guarantee efficiency?
Our fiberglass filter paper is manufactured and tested in strict accordance with international standards, including EN 1822 and ISO 29463. Every single batch of our HEPA (H13-H14) and ULPA (U15-U16) media undergoes 100% rigorous inspection using industry-standard TSI 8130 or Topas automated testing systems to verify penetration, resistance, and uniformity before slitting. We can provide Technical Data Sheets (TDS) and factory test reports with your shipment.
Q2: Can we customize the roll width, length, and specific technical parameters?
Yes, absolutely. As a source manufacturer, we offer comprehensive OEM/ODM customization services to perfectly fit your production needs. We can customize:
Roll Width: Slit precisely according to your automatic pleating machine specifications.
Roll Length: Standard lengths or jumbo rolls to minimize machine downtime during your processing.
Performance Tuning: We can adjust the binder formulation or fiber distribution to achieve lower pressure drop (low resistance) or specific basis weights based on your target application.
Q3: How does your fiberglass paper perform on high-speed automatic pleating machines?
Our fiberglass filter media is highly optimized for mechanical processing. By employing advanced wet-laid paper-making technology and premium eco-friendly binders, our paper delivers exceptional tensile strength and excellent stiffness. This ensures smooth feeding, crisp pleats, and zero fiber-shedding or cracking even when running on high-speed automatic knife-pleating or rotary-pleating production lines.
Q4: How do you pack the rolls to prevent damage during long-distance ocean freight?
Micro-glass fiberglass paper is sensitive to moisture and mechanical impact, so we implement robust export-standard packaging:
Each roll is tightly sealed in a thick plastic moisture-barrier bag with desiccant.
Wrapped in protective EPE foam cushioning to prevent edge damage.
Packed into heavy-duty corrugated cartons and securely stacked on fumigation-free pallets, reinforced with edge protectors and wrapped in stretch film for maximum stability during maritime transit.
Q5: What is your Minimum Order Quantity (MOQ) and lead time for international orders?
For standard grades (such as H13, H14, and F9), our MOQ is flexible to support your initial trial orders or machine calibration testing. For custom specifications or specific color/binder requirements, the MOQ depends on the production run width. Our standard lead time is typically 10 to 15 days after order confirmation, depending on the volume and customization requirements. Free samples (roll or sheet) are available upon request for your laboratory testing and approval.
