From H13 HEPA to U16 ULPA, from 250°C to 350°C+ high-temperature, from particulate filtration to molecular-level AMC control — Yiran® covers the apex of the filtration pyramid

High-Efficiency Filtration Pyramid

From E10 to U17, every Yiran® HEPA/ULPA filter is individually tested per EN 1822 to ensure actual efficiency for each element

Individual Scan · Efficiency Guaranteed

Every Yiran® HEPA/ULPA filter undergoes MPPS (Most Penetrating Particle Size) scan testing before shipment to ensure efficiency compliance. H13–H14 use PAO/DOP aerosol detection; U15–U16 are individually issued with efficiency certificates.

Benchmarked against leading international brand comparable products (H14 standard HEPA 610×610×78mm ΔP≈100Pa), Yiran® SEP series delivers comparable resistance levels at equivalent efficiency, with continuous optimization of MiniPleat spacing to reduce operating energy consumption.
