Fan Filter Unit filtration grade
Initial Filters (G1-G4)
Designed to capture large particles such as dust, hair, and pollen, these filters have a lower efficiency and are typically used as pre-filters to protect downstream medium and high-efficiency filters, extending their service life.
Medium Filters (M5-M6)
These filters are effective at capturing medium-sized particles like fine dust and fibers. With a higher filtration efficiency, they are commonly used in air conditioning and ventilation systems.
High-Efficiency Filters (HEPA, H10-H14)
HEPA filters are used to filter out very small particles, including bacteria, viruses, and smoke. With a filtration efficiency of over 99.97% for particles 0.3 microns and larger, they are widely used in cleanrooms, laboratories, and medical facilities where high air cleanliness is required.
Ultra-High-Efficiency Filters (ULPA, U15-U17)
ULPA filters are designed to capture ultra-fine particles with even higher efficiency, capturing over 99.999% of particles 0.12 microns and larger. They are primarily used in environments with extremely high air cleanliness requirements, such as semiconductor manufacturing and pharmaceutical industries.
