Filtration Levels

Six-Stage Purification System

From capturing coarse particles to molecular-level purification, Yiran® builds a complete product pyramid by filtration mechanism and efficiency grade

A Complete Air Purification Hierarchy

Air filtration systems typically comprise pre-filtration, medium-efficiency, high-efficiency, and ultra-high-efficiency stages in a multi-stage cascade, with chemical/molecular filtration stages added as needed. Yiran® offers standardized and customizable products at every level, ensuring the system maintains low resistance, high efficiency, and stable operation throughout its entire service life.

From commercial building comfort HVAC to pharmaceutical cleanrooms, microelectronics facilities, and gas turbine intake systems, Yiran®'s layered solutions have been widely deployed in scenarios with stringent air quality requirements. Every filter grade undergoes rigorous laboratory performance testing and on-site validation.
