Empowered by our state-of-the-art patented technologies, our proprietary **sterilizing antiviral HEPA filter range** sets a new standard for atmospheric cleanliness. They achieve an impressive PM2.5 concentration reduction down to 10 micrograms/m³—which outperforms the national clean standards by up to 5 times. Our anti-microbial treatments reliably stop the colonization of pathogens inside the filter folds, registering a sterilization efficiency of **99.9%** while achieving a H1N1 viral filtration index of **99.99%** without releasing secondary gaseous by-products.
A comprehensive engineering breakdown of synthetic media charge retention and particulate extraction parameters.
Within the ASHRAE 52.2 test standard framework, a **MERV 11** (Minimum Efficiency Reporting Value) rating designates a filter's capability to capture respirable particles down to the sub-micron scale. Unlike lower-tier MERV 8 filters that target larger dust motes, MERV 11 filters act as intermediate high-performance barriers. They are engineered to extract particulate matter within the 1.0 to 3.0-micron size band (classified under the **E2** efficiency metric) with an efficiency profile exceeding 65% to 79%, and large particles within the 3.0 to 10.0-micron band (**E3** efficiency metric) at an efficiency exceeding 85%.
This exact performance curve makes MERV 11 filters highly useful in cleanrooms and commercial environments. They capture mold spores, biological aerosol nuclei, fine soot, cement dust, and animal allergens. They work well without creating the high static pressure drops associated with MERV 13 or HEPA grades, which can strain standard HVAC blower motors.
Engineered with optimized pleat geometry and uniform media thickness. Delivers lower pressure drops (approx. 0.22" w.g. at 500 FPM) to save building energy.
Uses corona-charged polypropylene filaments. This electrostatic charge attracts fine particles without restricting airflow through tight mechanical pore structures.
Laminated with robust expanded wire mesh backing or dynamic cardboard reinforcements. Holds its shape under variable air volumes and high relative humidity.
At Shenzhen Snow Peak Clean Technology, we use advanced manufacturing processes to maintain these standards. By combining synthetic meltblown polymers with spunbond backing layers, we achieve high Dust Holding Capacity (DHC). This structural design prevents premature surface loading, extending the operational life of the filter element by up to 40% compared to typical fiberglass alternatives.

Take a virtual look inside our factory floor. We use automated pleating, robotic gluing, and high-precision CNC equipment to guarantee product quality.
At Shenzhen Snow Peak Clean Technology, our physical manufacturing capabilities back up our technical claims. We have over 15 years of international air purification engineering experience. Our facilities include dust-free filter fabrication suites, fully automated filter assembly lines, and high-performance testing stations.
We rely on advanced Japanese **AMADA CNC punching systems** and **CNC bending stations** to shape our metal-frame and heavy-duty separator variants. This ensures that every galvanized steel, aluminum, or stainless-steel filter shell is square, smooth, and leak-free. Our automated hot-melt glue systems place continuous, clean spacing lines across the media. This keeps the pleat spacing uniform even during high airflow spikes, preventing pleats from buckling and maintaining low system resistance.
How Shenzhen Snow Peak leverages localized supply chains, R&D agility, and scale to serve international B2B clients.
We run our own meltblown and synthetic media compounding lines. This direct control over production reduces dependency on external vendors and guarantees consistent quality.
Every batch undergoes strict testing for pressure drop and particle efficiency. We verify performance before shipping using TSI 8130 automated filter test rigs.
Based in the Shenzhen technology corridor, we quickly produce custom tools for special dimensions, pocket configurations, and frames in just a few days.
Our automated manufacturing processes reduce waste and lower labor costs. We pass these savings directly to our global ODM and OEM partners.
The southern Chinese industrial region, particularly Shenzhen, is known for its highly integrated manufacturing ecosystems. Shenzhen Snow Peak leverages this cluster by sourcing chemical components, frame extrusions, and sealing gaskets within a 50-kilometer radius.
By removing intermediaries and running our own meltblown and synthetic compounding lines, we maintain complete control over raw material quality. This lets us easily custom-formulate media parameters like electrostatic density and pore size distribution to match our clients' exact specifications. We can adjust the pressure drop profile or customize frame materials to meet specific compliance standards (such as EN779, ISO 16890, or UL 900) without delaying delivery schedules.
From microchip fabs to commercial HVAC units, see how our MERV 11 filtration setups help maintain clean air standards.
In microelectronics fabrication facilities and pharmaceutical packaging plants, MERV 11 filters act as reliable pre-filters upstream of expensive H13 HEPA and U15 ULPA ceiling modules.
Key Benefit: Captures larger particulates early to double the lifespan of downstream terminal HEPA filters.
Modern green office buildings need to balance Indoor Air Quality (IAQ) with energy efficiency. MERV 11 filters capture dust, soot, and mold spores while keeping energy usage low.
Key Benefit: Meets LEED certification requirements for air quality without needing expensive modifications to standard fan motors.
We manufacture direct-fit replacement filters for popular consumer air purifier and humidifier brands, including Honeywell (HRF-R3, HRF-AP100, and HRF-ARVP200 series).
Key Benefit: Identical fit and sealing behavior to original OEM parts, but at a more competitive price.
Our specialized filter formulations help buildings manage fine particulate risks (PM2.5). In cities with high levels of industrial emissions or smog, standard ventilation loops can quickly become overloaded.
Integrating Shenzhen Snow Peak’s antiviral and antibacterial media into a standard MERV 11 filter setup helps trap micro-particles and prevent microbial growth inside the HVAC system. This helps avoid secondary pollutant release and keeps indoor spaces cleaner and safer.
Streamlined logistics, robust protective packaging, and complete compliance documentation for global buyers.
Procurement managers at international enterprises must look beyond simple manufacturing unit costs. True cost efficiency is built on compliance, reliable delivery schedules, and optimized shipping volumes. Shenzhen Snow Peak provides comprehensive logistics support for ocean freight, air express, and overland transport, backed by our professional import/export division.
Our packaging processes are optimized for global transport. Rigid filters can easily be damaged by high humidity during long ocean shipments. We solve this by individually vacuum-wrapping each MERV 11 filter with desiccant packs before boxing them in heavy-duty double-walled corrugated master cartons. This keeps the electrostatic charges stable and prevents frame warping during ocean transit.
Furthermore, we supply complete certificate packages with every shipment. This includes CE compliance documentation, UL fire retardancy certificates, and raw batch testing data showing initial pressure drop curves. This ensures that your shipments clear customs quickly without unexpected delays.

Mechanical MERV 11 media captures dust solely through mechanical mechanisms like interception, inertial impaction, and diffusion. This requires a dense fiber web which increases resistance to airflow. Electrostatic MERV 11 media, like our corona-charged polypropylene, uses electrostatically charged fibers to attract and capture sub-micron particles. This allows for a more open fiber structure, resulting in a lower pressure drop and improved energy efficiency.
Many low-cost electret filters experience rapid charge decay when exposed to moisture or airborne oils, causing their efficiency to drop over time. We solve this by blending high-grade electret masterbatches into our polypropylene melts and using a dual-charge grid injection process. This anchors the dipoles inside the polymer fibers, helping the filter retain its charge even under high relative humidity.
Yes, our ODM division specializes in custom configurations. Thanks to our in-house automated pleating lines and AMADA CNC machines, we can produce custom frame depths and sizes without expensive tooling fees. Contact our sales engineering team with your drawings and target airflow specs, and we will prepare a prototype within 5 working days.
A standard 20ft container (approx. 4,000 to 5,000 standard pleated filters) takes about 14 to 21 working days to manufacture once drawings are approved. For repeat contract orders, we can maintain pre-built inventory in our warehouses to enable shipping within 48 hours.
HEPA filters capture at least 99.97% of particles down to 0.3 microns, but they create significant airflow resistance (often exceeding 1.0" w.g.). Most commercial HVAC systems are not built to handle this level of restriction. A MERV 11 filter provides a practical compromise: it captures over 65% of 1.0–3.0 micron particles with only a fraction of the pressure drop, helping maintain good air quality without overloading the HVAC blower.
