BACKGROUND ART Conventionally, air filters used in building air conditioners and the like are generally equipped with a coarse dust prefilter and a fine dust filter without a prefilter. In addition, in recent years, integral types of coarse dust prefilters and fine dust filters have been manufactured, but the fine dust filters used in these are generally of the single pleat type with a separator.

If a pre-filter for coarse dust and a filter for fine dust without a pre-filter are installed separately, the coarse dust re-dispersed from the pre-filter for coarse dust may cause
The life of the fine dust filter will be significantly shortened, and since the fine dust filter with an integrated pre-filter is a single pleat type with a separator, the pre-filter to which it is attached has a flat plate shape, so the filter area is small and the pressure is low. The disadvantage is that losses are high.
