Engineered for absolute particulates capture, compliance, and industrial-grade durability
As a leading integrated high-tech enterprise, we specialize in the comprehensive research, development, production, and distribution of premium air filtration products. Our multi-faceted approach spans raw material development to advanced filter manufacturing, allowing us to supply high-efficiency Pre-filters, pocket filters, HEPA filters, chemical filters, automotive cabin filters, and specialized humidifier media pads.
Equipped with our self-developed patented technology, our sterilizing and antiviral HEPA solutions do not merely trap particles; they active neutralize micro-biological targets. Our systems can suppress indoor PM2.5 concentrations down to 10 micrograms/m³, outperforming traditional national standards by 5 times. Our anti-viral filters deliver a sterilization rate of 99.9% while eliminating secondary release hazards, showcasing a removal efficiency of H1N1 viruses up to 99.99%.
"Leveraging 15 years of international air purification engineering experience to supply custom configurations for cleanrooms, pharmaceutical hubs, microelectronics factories, and institutional buildings."
Understanding structural performance differences, airflow properties, and system applications
Under the global air filtration standard EN 1822 / ISO 29463, HEPA 11 (technically classified as E11 Efficient Particulate Air filter) represents a critical class of media. Providing a minimum efficiency of 95% at the Most Penetrating Particle Size (MPPS), HEPA 11 strikes the ultimate balance between high-volume volumetric air movement and critical particle retention. This makes it an ideal pre-stage element or primary barrier where system static pressure budgets are strictly constrained.
| Filter Class (EN 1822) | Efficiency (at MPPS) | Typical Applications | Relative Pressure Drop (Pa) | Key Advantage |
|---|---|---|---|---|
| E11 (HEPA 11) | ≥ 95% | Commercial HVAC, high-end residential air purifiers, cleanroom pre-filters | 70 - 100 Pa (low resistance) | Extremely high airflow rate, lower energy footprint, protects downstream H13 elements. |
| E12 (HEPA 12) | ≥ 99.5% | Medical clinics, specialized vacuum cleaners, industrial ventilation | 90 - 130 Pa | Intermediate protection, balanced resistance and flow. |
| H13 (HEPA 13) | ≥ 99.95% | Pharmaceutical production, surgical theaters, semiconductor cleanrooms | 120 - 180 Pa | Industry standard for absolute particulate containment and safety. |
| H14 (HEPA 14) | ≥ 99.995% | Biosafety cabinets, toxic dust capture, absolute pathogen control | 140 - 220 Pa | Ultimate barrier control, highly restrictive flow requiring powerful blowers. |
15 Years of Air Purification Experience Combined with Leading Engineering Equipment
Our manufacturing facility houses fully automated production lines, a dedicated dust-free filter assembly workshop, and advanced machinery. We integrate precision AMADA CNC punch units, high-speed CNC bending machines, and custom pleating equipment. This technical foundation allows us to maintain strict tolerances, eliminate frame leakage, and produce customized shapes (cylindrical, rectangular, gel-seal, and pocket) to match any installation geometry.
Automated frame bonding and gasket sealant application.
High-precision cutting systems preventing edge fraying.
Uniform sealant distribution to ensure zero-bypass frames.
Multilayer lamination of electrostatic and carbon layers.
Hot-melt separator pleat optimization for smooth airflow.
Custom spacing configuration for specialized filters.
Why global brands source HEPA 11 and HEPA 13 filter systems from China
Direct access to localized melt-blown, fiberglass, and carbon fabric production. This proximity lowers raw material transit costs, secures raw feedstock consistency, and eliminates delays.
Equipped with computerized mechanical folding, automated frame sealing, and robotic test tracks. We reduce manual variation, providing consistency in physical frame geometry and leakage resistance.
All designs undergo rigorous quality testing. Each batch is verified via aerosol challenges (DOP/PAO testing) to guarantee conformity with CE directives, EN 1822, and ASHRAE standards.
Providing localized solutions for complex distribution networks and technical environments
Procuring high-efficiency filtration products involves navigating complex regulatory frameworks. At Shenzhen Snow Peak, we bridge the gap between Chinese supply chain cost-efficiencies and local target market expectations. Whether designing custom frames for European HVAC systems or matching UL 900 flammability classifications in the US, our cross-border project engineering team ensures seamless implementation.
Our ODM and OEM services are structured around localized demands. We understand that global climates, mechanical building codes, and regional voltage standards dictate different HVAC air handling designs. Our engineering services provide:
The transformation towards low-pressure-drop, anti-microbial, and sustainable air systems
Modern HVAC filtration faces a dual challenge: lowering energy consumption while maintaining absolute safety. Traditionally, high-grade HEPA filters created high static resistance, requiring powerful, energy-consuming fan systems.
To combat this, our research and development team focuses on hybrid composite matrices. By integrating structural nanofiber layers with electrostatically charged melt-blown media, we achieve E11 and H13 filtration classes at a fraction of the pressure drop.
Additionally, the integration of patented antimicrobial surface treatments allows our media to deactivate pathogens upon contact, preventing micro-biological growth on the pleat surface—a critical factor for pharmaceutical complexes and critical indoor environments.
