Medium efficiency air filter

Definition: It is mainly an air purification product that filters dust particles with a particle size of around 0.5 μ m-5 μ m.

Medium efficiency filters belong to the M and F series filters in the EN779 standard. There are two types of medium efficiency air filters: bag type and non bag type. Bag type filters include M5, M6, F7, F8, F9, non bag type, plate type medium efficiency filters, partition type medium efficiency filters, and V-shaped medium efficiency filters.   

Note: (F5, F6, F7, F8, F9) represents the filtration efficiency (0.4 μ m particle count), F5：40~60%，F6：60~80%，F7：80~90%，F8：90~95%。
