ABSTRACT:
An improved filtering bag combination having an increased area of filtering and a longer life of use. The improved structure includes a filtering member with multiple folds to cover a support formed of a plurality of rods. The rods of the support have a plurality of bracing members to support the filtering member, two ends of the support are mounted with two shaping pieces, and an upper and lower lid for fixing and sealing. The bracing members are all serrated members, and are provided on the outside with numerous equidistantly separated crests and corresponding hollows and on the inner side with a connecting base. The crests each have a clamping notch for placing a rod, so that the bracing members can be transversely arranged within a circle formed by encircling the rods of the support.
