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, pharmaceuticals, laboratories, schools, cleanrooms, and hospitals. 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%.
The 20x20x1 inch dimensional configuration represents the industry standard for light commercial and heavy residential HVAC return grilles. However, when loaded with premium-grade activated carbon, this form factor transforms from a simple particulate barrier into a highly sophisticated chemical adsorption engine. This section details the material science, residence time dynamics, and structural geometry of our CE certified filters.
Our activated carbon media utilizes premium coconut shell raw material with a Carbon Tetrachloride (CTC) rating exceeding 60%. This yields a microscopic pore structure optimized for gaseous contaminants, organic vapors (VOCs), and indoor odor molecules, ensuring maximum retention per gram.
Maintaining a low initial pressure drop is essential for HVAC blower health. The pleated layout of our 20x20x1 filters increases the effective surface area by 2.4x compared to flat-pad alternatives. This keeps resistance low while extending the physical life of the filter.
By blending physical particulate filtration with gas-phase chemical adsorption, the filter captures larger airborne debris (PM10 to PM2.5) while neutralizing chemical pollutants such as formaldehyde, benzene, and localized ozone emissions.
Having 15 years of international air purification technology experience as the background, our company has standardized production workshops, dust-free filter workshops, and first-class technology of HEPA filters production line and inspection line. Our production facilities feature fully automatic air filter lines, equipped with AMADA CNC punches and CNC bending machines to guarantee dimensional tolerances and structural integrity.
The requirement for gas-phase filtration spans multiple commercial and industrial landscapes. As compliance criteria tighten across North America, the European Union, and Asia-Pacific regions, the implementation of heavy-duty, thin-profile carbon filters has become vital to maintain clean air.
In wafer fabrication and semiconductor manufacturing, Airborne Molecular Contamination (AMC) can compromise delicate lithography processes. Installing 20x20x1 carbon filtration panels in the recirculation loop removes trace outgassing from volatile construction materials, protecting high-yield production runs.
Urban commercial complexes face constant threats from outdoor ozone, exhaust fumes, and traffic emissions. Incorporating CE-certified carbon media inside high-velocity HVAC systems reduces indoor VOC levels while keeping energy use low, helping operators meet regional environmental building standards.
Sterile spaces require strict control over chemical compounds such as sterilizing agents, laboratory reagents, and cleaning residues. Combining our high-efficiency particulate technology with gas-phase carbon adsorption helps stabilize indoor environments and prevent cross-contamination.
Shenzhen Snow Peak's research and development division is advancing carbon media design. Our technical roadmap aims to resolve the classic trade-off between filter longevity, adsorption rate, and system flow resistance.
By integrating electrospun nanofibers with highly porous carbon matrices, we are developing a single-layer media capable of concurrent sub-micron particulate filtration and rapid molecular gas capturing. This reduces the overall footprint while matching dual-stage filtration performance.
Future formulations include advanced chemical impregnants (such as potassium permanganate and metal-organic frameworks) designed to oxidize targets like formaldehyde, hydrogen sulfide, and sulfur dioxide. This extends the service life of filters deployed in demanding industrial environments.
For international enterprise buyers and HVAC distributors, supply chain transparency and consistent quality are critical. Operating out of Shenzhen, the hub of global hardware manufacturing and export logistics, Shenzhen Snow Peak Clean Technology guarantees both speed-to-market and compliance with European and global regulations.
Every batch of 20x20x1 activated carbon filters undergoes standard testing before dispatch. From raw carbon quality checks to structural integrity drop testing of the final cardboard frame assembly, we ensure all components meet the European CE certification criteria, allowing for direct import and distribution across EU member states.
We support diverse design requirements. Whether you need moisture-resistant beverage board frames for humid conditions, metal mesh wraps for industrial vibration isolation, or customized branding, our engineering team utilizes automated CNC equipment to rapidly transition from custom CAD design to final product delivery.
