Abstract:
A filter medium, a filter into which the filter medium is installed, and an apparatus for supplying air and chemicals equipped with the filter. The filter medium has a sheet including a first pleated portion, which is folded in a first wave shape such that a first amplitude and a first wave length are formed in the first pleated portion. The filter medium also includes a second pleated portion, which is folded in a second wave shape such that a second amplitude, less than the first amplitude, and a second wave length, shorter than the first wave length, are formed in the second pleated portion. At least one second pleated portion is formed in the first pleated portion.
