Medium-Efficiency Air Filters
Professional medium-efficiency air filtration solutions, providing continuous protection for cleanroom systems.
About Us
We are leading Medium-Efficiency Air Filter Manufacturer in china, specializing in the R&D and production of medium-efficiency filtration products for clean air systems. With over a decade of experience in the air filtration industry, we understand that medium filters serve as the pivotal hub within the entire air purification hierarchy of cleanroom systems. They not only bridge the gap between primary and high-efficiency filtration stages but also directly impact the system’s overall cleanliness, energy consumption, and maintenance cycles.
Our products are extensively deployed in high-standard environments such as pharmaceutical plants, electronics factories, medical cleanrooms, biological laboratories, food processing facilities, automotive paint lines, and HVAC systems. They fully comply with international air filtration standards including ISO 16890, EN779, and ASHRAE 52.2.

What is a Medium-Efficiency Air Filter?
Medium-efficiency air filters are filtration devices designed to capture airborne particles ranging from 1 to 10 micrometers in diameter. They are typically installed as the second stage of filtration in air purification systems, positioned between primary and high-efficiency filters.
Their primary functions include:
- Effectively removing medium-sized dust and suspended particles;
- Extending the service life of high-efficiency filters (HEPA/ULPA);
- Stabilizing airflow volume in supply systems to reduce operational energy consumption;
- Ensuring air cleanliness remains consistently stable at the target level.
