HEPA filters can stably capture 0.3μm particles with a filtration efficiency of up to 99.99%. They are the core high-efficiency filtration components in air purification systems, mainly corresponding to the H13–H14 filtration levels of the EN1822 standard. Using ultra-fine glass fiber filter paper or PTFE membrane as filter media, combined with a uniform and stable pleated structure, they can effectively capture particles ≥0.3 μm, including smoke, oil mist, PM0.3–PM2.5, virus carrier particles, bacterial attached particles, microbial spores, and precision manufacturing particulate pollutants. HEPA filters are typically used as end-point filters in cleanrooms and are a key component in ensuring that the environment achieves ISO5–ISO7 cleanliness levels.
Product Advantages
Ultra-high filtration efficiency (99.97%–99.999%) – Passes EN1822 H13/H14 full inspection
H13: ≥99.97%
H14: ≥99.995%
MPPS (Most Penetrating Particle Size) test passed
100% scan leak detection (not random sampling)
We use imported German MPPS scanners to test each filter individually, ensuring no leaks or dead zones on each product – something many manufacturers on the market cannot achieve.
Low resistance + energy-saving design (12–20% lower than competitors)
We have optimized the pleat depth, filter media uniformity, and airway spacing, enabling the HEPA filter to maintain low pressure drop while ensuring high efficiency:
Initial resistance is 12–20% lower than the industry average
Significantly reduced power consumption
More energy-efficient operation of FFUs and cleanroom terminal systems
Low resistance means lower energy consumption, longer lifespan, and lower HEPA replacement costs.
Longer Service Life (25-40% longer than standard HEPA filters)
Thanks to higher dust holding capacity filter media, a larger effective filtration area design (optimized pleat density),
and a more stable seal structure, many engineering projects have reported that
SYNRUI's HEPA replacement cycle has been extended from an average of 1 year to 18-24 months.
This is key to continuous cost savings for businesses.
High-Strength Sealing Structure Ensures No Leakage Risk
We use aerospace-grade PU adhesive, high-sealing EVA material, and food-grade gel seal technology to ensure that the HEPA filter does not deform, loosen, or leak under high-pressure conditions.
Especially the gel seal HEPA filter, which guarantees seamless installation, one-time installation, and zero leakage risk.
Suitable for critical applications in pharmaceuticals, biotechnology, and hospitals.

FAQ
Q: 1. What is the difference between HEPA and ULPA?
A: ULPA is more efficient (99.9995%) and suitable for extremely high-level cleanrooms. HEPA is the mainstream high-efficiency level.
Q: 2. What are the standards for HEPA?
A: We offer H13 and H14 HEPA filters that meet EN1822 standards.
Q: 3. Can HEPA filters be customized in size?
A: Yes, we support customization of all specifications, including FFUs, terminal air outlets, and HEPA box sizes.
Q: 4. Why do your HEPA filters have lower resistance?
A: Because we have optimized the pleat depth and airflow distribution, increasing the effective filtration area and reducing airflow resistance.
Q: 5. What is the typical lifespan of a HEPA filter?
A: 12–24 months, depending on the environment and pre-filtration level.
Q: 6. What temperature can high-temperature HEPA filters withstand?
A: We offer two high-temperature series: 250°C and 350°C.
Q: 7. Does the HEPA filter require 100% scanning?
A: Yes, especially for pharmaceutical and biopharmaceutical applications. We default to 100% scanning of all HEPA filters.
Q: 8. Can the HEPA filter be used with FFUs?
A: Yes, we offer dedicated panelless HEPA filters that are perfectly compatible with various FFU systems.
Q: 9. Can the HEPA filter be used in ISO 5 cleanrooms?
A: H14 is recommended for ISO 5 and higher cleanroom standards.
Q: 10. Can you provide samples? What is the lead time?
A: Samples can be provided. The lead time for standard HEPA filters is 7–10 days, and for bulk orders, it is 15–20 days.
