HEPA Filters for Cleanrooms, HVAC and Critical Air Quality Control
Procuring HEPA filters for pharmaceutical ISO 5 cleanrooms requires strict adherence to leak-free performance. HuiXiang supplies EN1822 certified H13 and H14 filters, utilizing imported fiberglass media. By optimizing the pleat spacing with hot-melt separators, we reduce aerodynamic drag, achieving an initial pressure drop below 250Pa at a face velocity of 0.45m/s.
EN1822 Efficiency Grades
H13 (99.95%) & H14 (99.995%) individually DOP tested.
Low Resistance Design
Mini-pleat structure maximizes media area, lowering energy costs.
Cabinet Compatibility
Available in 69mm, 90mm, and 292mm depths with EVA or Gel seal.
Mass Production Stability
Automated pleating lines ensure consistent pleat height and spacing.
Filtration Solutions by Application
Designed for environments where air cleanliness directly affects product yield, equipment lifecycle, and operational compliance.
Cleanrooms
HEPA and ULPA ceiling modules for ISO Class 1-5 controlled production environments.
Hospitals & Clinics
Air filtration solutions for operating theaters and negative pressure isolation wards.
Pharmaceutical
High-temperature HEPA filters for sterile manufacturing and drying tunnels.
Electronics & Semi
PTFE media filters addressing boron-free requirements in wafer fabrication.
Nuclear Power
Deep-pleat HEPA filters with metal separators engineered for high-radiation zones.
Gas Turbines
V-bank rigid filters preventing compressor blade fouling in power generation.
Industrial Dust
Pleated filter cartridges for welding fume extractors and powder coating lines.
Commercial HVAC
Bag filters and panel filters extending the lifespan of terminal HEPA units.
From Filter Media to Finished Filter Assembly
Unlike pure assembly workshops relying entirely on outsourced media, HuiXiang operates in-house media pleating lines and dispensing equipment. When you face irregular cabinet mounting holes, our engineering team modifies the structural design before prototyping.
Our internal laboratory conducts initial pressure drop and dust holding capacity tests, validating that the final assembly meets the targeted airflow parameters without premature clogging.

- Air Filter Manufacturing & Assembly
- Filtration Performance Testing (DOP)
- Custom Frame Design (Aluminum/Galvanized/SS)
Tested to Recognized Filtration Standards
Procurement compliance requires verifiable data. HuiXiang designs air filtration products according to EN779 and EN1822 standards. Our CE certified production processes ensure that structural integrity, media velocity, and sealing techniques meet the rigorous demands of industrial HVAC and cleanroom contractors.
Solutions for Different Filtration Challenges
Match your specific pressure drop limits, airflow targets, and contamination types with the right structural design.
Need high efficiency air filtration for ISO cleanrooms?
When terminal filtration requires strict particle control (0.3μm), standard pre-filters are insufficient.
Recommended: H14 HEPA Filter / Mini Pleat HEPA Filter
Need lower pressure drop in high-volume HVAC?
For systems struggling with fan energy costs, expanding the filtration area reduces media velocity and resistance.
Recommended: V-Type Rigid Filter / Synthetic Bag Filter
Need odor, VOC, or gas phase control?
Particulate filters cannot capture molecular contaminants. Activated carbon media is required for gaseous adsorption.
Recommended: Activated Carbon Filter / V-Bank Carbon Module
Need custom dimensions or special frame interfaces?
When retrofitting legacy equipment where standard 592x592mm sizes do not fit your existing mounting rails.
Recommended: Custom HEPA Filter / OEM Filter Manufacturing
