Explore our premium range of primary, secondary, and HEPA filter units engineered for durability and efficiency.
Within large-scale industrial and commercial HVAC systems, the primary filtration layer serves as the vanguard protecting high-efficiency secondary and terminal HEPA filters. Custom AHU Pre-Filters (Washable) represent an evolutionary step forward, combining environmental stewardship with highly cost-efficient lifecycle management. Traditionally, primary pre-filters—typically rated G2, G3, or G4 under standard EN 779 / ISO 16890—were conceptualized as disposable items. However, the modern transition toward circular economic models has established high-performance washable synthetic media as the standard for international procurement.
As a leading designer and exporter in this space, Shenzhen Snow Peak Clean Technology Co., Ltd. integrates top-tier R&D with advanced precision manufacturing to deliver customizable, multi-washable pre-filters that maintain structural integrity and electrostatic charge capacity even after intensive washing cycles. By using high-durability materials like extruded aluminum alloys, stainless steel, and galvanized frames coupled with heavy-duty synthetic nylon mesh or media, our designs minimize resistance, reduce replacement intervals, and lower the Total Cost of Ownership (TCO) across complex HVAC infrastructures.
Shenzhen Snow Peak Clean Technology Co., Ltd. - An Integrated High-Tech Enterprise
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, and more.
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%.
Globally, China serves as the anchor of specialized cleanroom and air filtration production supply chains. At Shenzhen Snow Peak, this advantage is not merely about cost efficiency; it is a synthesis of cutting-edge raw material access, technological agility, and high-performance automation. We offer unique manufacturing values that set us apart on the international market:
Equipped with high-end CNC lines, including AMADA CNC punch systems and advanced bending machines, we ensure the structural integrity of customized aluminum or stainless-steel frames. Our automated gluing and pleating lines deliver uniform pleat spacing and zero bypass leaks.
Every washable pre-filter and high-efficiency HEPA component is subjected to strict quality assessments. Our in-house detection lines measure initial pressure drop, dust holding capacity (DHC), and wash cycles before exporting to ensure zero-defect delivery.
Leveraging Shenzhen’s global shipping infrastructure, we process bulk shipments for air handling units seamlessly. We support specific requirements such as anti-vibration framing, custom dimensioning, and specialized media laminations.

Continuous automated hot-melt distribution ensures zero bypass pathways.
Dimensional stability achieved through computerized industrial cutters.
Hermetic frame-to-media sealing to resist high mechanical pressures.
Laminating functional materials like active carbon and antimicrobial layers.
Maximizes filtration surface area and reduces initial pressure drop.
High speed, uniform folding configuration to maintain stable air stream pathways.
The global ventilation market is undergoing an era of strict environmental auditing. The modern trend in commercial building management is directed toward decreasing the energy expenditure of primary ventilation runs. Air handling units (AHUs) consume a significant amount of electricity due to fan pressure differentials. Utilizing cleanable pre-filters helps in reducing resistance over longer periods:
Requires ISO Class 3 to Class 6 environments. Custom washable pre-filters act as the crucial preliminary barrier in recirculation air units, protecting high-cost chemical filters and terminal ultra-low penetration air (ULPA) systems.
Designed to comply with GMP regulations. Washable filters in cleanrooms prevent bio-aerosols and large dust structures from taxing secondary layers, offering high stability under disinfectant washing.
Our antiviral pre-filters and HEPA configurations inhibit pathogens like H1N1 (efficiency up to 99.99%), reducing secondary cross-contamination risks within high-traffic HVAC units.
Having 15 years of international air purification technology experience as the background, our company has standardized production workshops, dust-free filter workshops, and a first-class technology of HEPA filters production line and inspection line. Our independent research and development of fully automatic air filter production lines is equipped with AMADA CNC punches, CNC bending machines, and other advanced high-end equipment. This provides a strong guarantee for the production capacity, precision, and overall quality of our air filtration and purification products.
We work closely with global engineering procurement contractors (EPCs) to provide bespoke sizing options. Whether you require standard G3/G4 ratings or specialized custom dimensions with metal frame mesh reinforcements, our team can deliver solutions that integrate into any HVAC or air handling unit design.
