Explore our industrial HVAC filters, custom replacement HEPA components, and raw filtration media designed to meet EU EN1822 & ISO 29463 guidelines.
Shenzhen Snow Peak Clean Technology Co., Ltd. is an integrated high-tech enterprise, specialized in air filtration products research and development, production, sales, import and export trade. We produce and supply: Pre-filter, pocket filter, HEPA filter, chemical filter; replacement HEPA filter, car cabin air filter, humidifier filter; pocket filter media, melt-blown composite filter media, and other high-performance filter materials.
We provide high-quality air purification solutions and products for indoor air pollution control and air conditioning systems of civil and industrial buildings, microelectronics, pharmaceutical, laboratory, school, hospital clean rooms, etc. Combined with self-developed patented technology, our sterilizing antiviral HEPA filter can effectively filtrate fine particles, so that PM2.5 concentration down to 10 micrograms/m3, 5 times better than national standard; effectively inhibit the breeding of microorganisms, sterilization rate up to 99.9%, and no secondary pollution, removal of H1N1 virus efficiency as high as 99.99%.
Designing commercial and industrial HVAC air filtration demands deep understanding of mechanical filtration dynamics. When sourcing OEM/ODM HEPA systems, industrial buyers must evaluate structural configuration, pressure drop dynamics, and particle retention levels. HVAC units must withstand high air volumes without suffering excessive static resistance, which causes system wear and increases energy costs.
To balance high dust holding capacity (DHC) with low initial differential pressure, Shenzhen Snow Peak relies on computerized pleat geometric distribution, high-density microfiber glass, and synthetic composite fabrics. The table below represents the core parameters across standard commercial and cleanroom configurations.
| Filter Class (EN 1822) | Efficiency @ MPPS | Common Frame Materials | Initial Pressure Drop (Pa) | Primary Industrial Applications |
|---|---|---|---|---|
| G3 - G4 (Coarse) | ≥ 90% (Arrestance) | Cardboard, Galvanized Steel, Alu | 30 - 50 Pa | Pre-filters for AHU, painting exhaust loops, residential HVAC |
| M5 - F9 (Medium) | 40% ≤ ePM1 ≤ 95% | Synthetic Bags, Metal Headers | 60 - 120 Pa | Food production pre-filtering, pharmaceutical primary stages |
| E11 - E12 (EPA) | ≥ 95% - 99.5% | MDF, Extruded Anodized Aluminum | 100 - 150 Pa | Hospital general wards, specialized mechanical assembly lines |
| H13 - H14 (HEPA) | ≥ 99.97% - 99.995% | Anodized Aluminum, Stainless Steel | 120 - 250 Pa | Semiconductor cleanrooms, biotech labs, containment units |
Our 15-year background in international air purification technology has guided us to design and operate fully automated production lines, ensuring high quality control and assembly stability.
Automated two-component polyurethane dispensing systems to guarantee leak-free perimeter seals between media packs and outer housings.
High-speed dimensional cutting stations providing precision media edges with zero fiber fraying, maintaining structural integrity.
Hot-melt adhesive micro-ribbing spacing systems that preserve optimum air passage channels and prevent pleat collapse.
Multi-layered material bonding that combines high mechanical arrestance glass fibers with electrostatically charged synthetic barriers.
Servo-driven rotary and knife pleating stations that adapt to custom depths ranging from 8mm to 150mm for tailored air volume loads.
Post-pleat stabilization and inspection ensuring parallel spacing alignment and mechanical uniformity before final assembly.
Worldwide demand for sub-micron particulate isolation has shifted from a specialized cleanroom necessity to a baseline commercial requirement. Globally, strict occupational safety frameworks (such as ASHRAE Standard 62.1 and European EN 13779 guidelines) now regulate indoor air quality in response to airborne pathogens and rising urban pollution levels. At the same time, the rise of modern industries like semiconductor fabrication, optoelectronics, bio-pharma, and aerospace manufacturing has led to a major increase in the use of localized high-efficiency filters.
To maintain efficiency without driving up operational costs, facility engineers are moving away from traditional single-layer glass fiber panels. The market is shifting toward multi-stage filtration cascades, which pair coarse G4/M5 pre-filters with F7/F9 pocket filters and H13 HEPA terminals. This approach prevents premature HEPA loading and reduces energy consumption across the fan network. Shenzhen Snow Peak supports this trend by offering customizable ODM design options, allowing buyers to select specific frame materials, pleat patterns, and chemical media combinations to meet their system's exact pressure and flow requirements.
Optimum pleat geometry reduces drag, lowering fan energy draw by up to 22% compared to standard designs.
Every HEPA module is scan-tested using ISO 29463 methodologies to guarantee full compliance with global safety standards.
15 years of industry-grade clean air research helps us continually improve filtration media longevity and performance.
Working with a reliable Chinese ODM HVAC HEPA manufacturer like Shenzhen Snow Peak provides global buyers with several key benefits, including advanced automation, raw material integration, and scalable production capacity. We maintain full control over the production process, from meltblowing synthetic polymers to pleating glass fibers and fabricating metal frames. By sourcing materials directly and handling manufacturing in-house, we can react quickly to supply chain shifts and keep production costs competitive.
Additionally, our facility features high-precision machinery, including AMADA CNC punch and bending equipment, automated double-glue dispensing lines, and dedicated cleanroom assembly halls. This advanced automation minimizes human error and guarantees consistent quality across large production runs. We also run full-scale batch leak tests to ensure our filters meet European and American compliance standards, providing international distributors with reliable performance.
When sourcing industrial HEPA filters, procurement teams should look beyond unit costs and focus on technical specifications to ensure long-term system performance:
