Explore our elite product inventory engineered to fit top commercial and consumer purification units. Designed for maximum mechanical efficiency, high dust retention, and low pressure drop.
Minimum Efficiency Reporting Value (MERV) standards have long acted as the benchmark for evaluation of HVAC air filtration efficacy. However, as the boundaries of microelectronics, nanofabrication, and molecular pharmacology advance, common standards are being pushed to the absolute extreme. A MERV 20 rating sits at the pinnacle of standard ashrae 52.2 classifications, operating in the Ultra-Low Penetration Air (ULPA) spectrum. To achieve a MERV 20 certification, the filter material must capture 99.999% of particulate matters in the 0.1 to 0.2 micron size range.
This extreme parameter makes MERV 20 materials structurally distinct from domestic fiberglass or standard melt-blown non-wovens. They utilize advanced polymer arrangements and chemical electret properties to intercept even the smallest viral carriers, sub-micron ash particles, and chemical crystallization agents. As leading global exporters, we specialize in delivering the multi-laminated structures that allow operations to maintain compliance while preserving system integrity.
In cleanrooms, energy consumption is directly correlated with air pressure drop. Conventional glass-fiber high-efficiency media demands significant blower power. Our new composite materials represent a fundamental shift, substituting thick traditional glass fibers with multi-layered, ultra-fine synthetic melt-blown arrays combined with structurally sound mechanical carrier backings. The result is a media that optimizes airflow pathways while enforcing an absolute barrier against contaminants.
Shenzhen Snow Peak Clean Technology Co., Ltd. is a globally recognized, fully integrated high-tech enterprise specializing in air filtration products research, development, production, and international import-export operations. By matching cutting-edge clean-technology paradigms with raw material superiority, we supply high-performance solutions across five continents.
Our product suite spans a massive range of critical requirements including Pre-filters, pocket filters, HEPA filters, chemical filters, replacement HEPA filters, automotive cabin air filters, and humidifier filters. Beyond standard assemblies, we produce the core media itself—supplying pocket filter media, melt-blown composite filter media, and other high-performance materials for direct integration into global manufacturing streams.
Leveraging our self-developed patented technology, our sterilizing and antiviral HEPA solutions can effectively filter fine particles to bring local PM2.5 concentrations below 10 micrograms per cubic meter—performing 5 times better than typical national thresholds. By combining chemical and electrostatic mechanisms, our media inhibits micro-organism growth on the filter bed, achieving an active sterilization rate of 99.9% while completely removing H1N1 virus with 99.99% efficiency without inducing secondary dust-off or organic emissions.
Understanding the exact placement of MERV 20 materials requires comparing them against standard grades. Below is the technical performance index map detailing efficiency ratings, primary particulate targets, and typical industrial destinations.
| Classification Grade | Efficiency Rating (0.1–0.3 µm Particles) | Media Construction Type | Resistance Class (Initial Pressure Drop) | Primary Industrial Sector |
|---|---|---|---|---|
| MERV 13 - 14 | < 75% | Coarse Synthetic / Fiberglass Blend | Low (35 - 75 Pa) | Commercial Office, Residential HVAC, Prefiltration |
| MERV 16 (H11/H12 equivalent) | > 95% | Standard Electret Melt-blown | Medium (80 - 120 Pa) | Hospitals, Food Prep Facilities, Standard Labs |
| MERV 17 - 19 (H13/H14 HEPA) | 99.97% - 99.995% | Dense Glass Microfiber / Pleated Composite | High (120 - 250 Pa) | Bio-pharma Cleanrooms, Operating Rooms, Electronics |
| MERV 20 (U15 - U16 ULPA equivalent) | > 99.999% | Ultra-fine Nanofiber Poly-composite / PTFE Matrix | Optimized Low (150 - 220 Pa) | Semiconductor Fabrication, Nanotechnology, Nuclear Containment |
Backed by over 15 years of international air purification technology experience, our state-of-the-art facilities comprise standardized dust-free filter workshops, automated testing complexes, and high-precision machinery. Our facility features premium CNC processing machines including AMADA CNC punches and CNC bending machines to ensure absolute housing structural precision, alongside proprietary automated pleating and gluing lines.
For engineers and procurement heads, selecting a MERV 20 or ULPA media involves balancing multiple structural factors. We design our proprietary composite structures to directly solve these primary system pain points:
By shifting to composite sub-micron meltblowns, our MERV 20 media reduces air resistance by up to 25% compared to legacy fiberglass. This translates directly to lower fan load requirements and substantial annual energy savings for manufacturing plants.
Rather than merely trapping pathogens, our specialized antiviral coatings actively disable microbes on contact. Our certified tests indicate a 99.99% inactivation rate of H1N1 viruses, preventing biological contamination of the filter surface.
For microelectronics and semiconductor fabs, organic compounds (VOCs) outgassing from filter binders can ruin silicon wafers. Our synthetic media uses clean mechanical bonding and high-purity polyurethane gaskets, showing zero organic outgassing.
Procuring MERV 20 / ULPA filtration materials at scale presents unique supply chain complexities. Quality managers must verify consistency, transport safety, and compliance with dynamic environmental laws. At Shenzhen Snow Peak, we address these challenges through optimized logistics and complete quality control protocols.
Different HVAC configurations require specific design treatments. We offer extensive OEM/ODM customization options covering media thickness, physical pleating depth, and frame material configurations (including anodized aluminum, galvanized steel, and cleanroom-grade cardboard frames). This custom versatility ensures perfect integration into FFU (Fan Filter Unit) systems, terminal HEPA boxes, and mobile air purification units.
Every roll of filter media and finished cartridge undergoes strict performance validation. Using state-of-the-art particulate detection instruments and oil aerosol tests (DOP/PAO), we inspect media consistency, pore size uniformity, and pressure drop. Our certification suite includes CE and ISO, providing global buyers with the assurance required for high-risk biosafety and electronics environments.
Due to the sensitive nature of high-efficiency filters, shipping damage can compromise performance. We utilize reinforced, vacuum-sealed packaging and high-durability external wooden crates to prevent media deformation or moisture absorption during long-distance maritime transit. This ensures that materials arrive at your facility in pristine condition, ready for installation.
The air filtration industry is undergoing rapid innovation. The demand for cleaner air is no longer limited to high-tech manufacturing; it is now critical in commercial complexes, modern residential areas, and medical centers.
