Well suited for the fine filtration in air handing systems and units, and as pre-filters for HEPA filters. F5 to F9 fine filters wholly can be used as the pre-filters. F5 is mainly for the ventilation system for comfortable air supply for offices or buildings. F7 is to prevent the specks engender in the air supply ceiling. F8 can be used as the final filters for 300,000 -class clean room. F9 can be used as the final filters for 100,000 -class clean room.
