Newly operational 7,000-square-meter facility delivers 50,000-plus daily unit capacity with in-house EN 1822 testing, supporting large-scale custom HEPA filter orders for appliance, automotive, and HVAC clients.
— Suzhou HIFINE Environment Protection Technology Co., Ltd., a leading HEPA air filter manufacturer with 13 years of OEM/ODM experience, today announced that its expanded Suzhou manufacturing facility is now fully operational. The 7,000-square-meter plant, located along Yangcheng Lake in Xiangcheng District, significantly increases the company’s high-volume custom HEPA air filter production capacity, enabling HIFINE to accept and fulfill large-scale OEM orders for global appliance, automotive, and HVAC brands.
The fully online facility supports a daily output of more than 50,000 filter units across HIFINE’s complete product range, with dedicated production lines for H10 through H14 HEPA-grade air purifier filters. The expansion strengthens HIFINE’s position as a single-source manufacturing partner for brands requiring custom filtration solutions at scale, from initial prototyping through mass production.
“Bringing this facility fully online is a milestone for us and for our partners,” said a HIFINE spokesperson. “For 13 years, we have focused on one thing, building filters that perform consistently batch after batch. This plant gives us the capacity, the automation, and the testing infrastructure to deliver that consistency at a scale that global brands need. Whether a partner needs 5,000 custom units for a product launch or 500,000 units for an established appliance line, we can handle it under one roof.”
Automated Production and In-House Quality Validation
The Suzhou facility operates multiple automated production lines with integrated quality control at every manufacturing stage. Raw materials undergo incoming inspection before entering production, and each batch is monitored through pleating, framing, sealing, and final assembly. Full production traceability allows HIFINE to track any unit back to its raw material lot and production parameters.
Crucially, the facility houses on-site testing laboratories that validate filtration efficiency against international standards, including EN 1822 for HEPA-grade media and ISO 16890 for general ventilation filters. This in-house testing capability means every performance claim is verified before shipment, reducing the risk of field failures and warranty claims for brand partners.
Custom Engineering at Scale
HIFINE’s high-volume customization capability is backed by an in-house R&D and tooling team that works directly with brand partners on custom mold design, material selection, and prototyping. The company holds 27-plus patents covering filter media, structural design, and manufacturing processes. New filter specifications can move from concept to production-ready samples without relying on third-party subcontractors, shortening development cycles and protecting proprietary designs.
The company’s custom HEPA air filter portfolio includes:
- H10 to H14 HEPA filter media and finished air purifier filters
- Custom-sized pleated HEPA panels for HVAC and commercial systems
- Activated carbon combined HEPA filters for odor and VOC reduction
- Vacuum cleaner HEPA exhaust filters
- Automotive cabin air filters
- Cross-compatible replacement filters for major air purifier brands
This breadth allows HIFINE to serve as a single-source OEM/ODM supplier across multiple product categories, reducing supply chain complexity for brands that manage diverse filtration catalogs.
Certified Manufacturing, Global Reach
HIFINE holds National High-Tech Enterprise recognition, ISO 9001 quality management certification, and BSCI compliance. The company’s filters currently reach more than 100 countries and regions through distributors, wholesalers, and private-label brand partners. HIFINE supports partners across the full order spectrum, from small-batch trial orders for emerging brands to high-volume OEM contracts for established manufacturers, with engineering support available at every stage.
