To reduce air resistance and to improve efficiency in deodorization by uniformly filling a water-washable deodorization filter used for an air cleaner or an air conditioner with a large amount of a deodorizer.

The deodorization filter 1 is formed by forming a plurality of bags 4 of a three-dimensional woven knitted good consisting of two sheets of mesh-state fabric 2a and 2b and spacer parts 3, and filling these bags 4 with the deodorizer. The two sheets of mesh-state fabric are arranged nearly parallelly separated from each other by the height of partitions 3 consisting of spacer yarns to form the bags 4, so that the thickness of the deodorizer with which the bags 4 are filled is made to be nearly constant in all the areas of deodorization filter.
