TEDA FILTERS Pocket filters material（C-III and B-II series) are all in bi-componont structure, in that, the super-fine MB fiber give the nonwoven higher filtration efficiency and the 3D crimp staple fiber convey excelent compression resilince property. The two fibers are blended in structure of “Z” shape,which makes the filter media featured with higher air permeability and dust holding capacity, more importantly, it can decrease the pressure drop raising up during its using.

So they are ideal filtration media for the applications requesting higher dust holding and low resistance synchronously. B-II series has one more pre-filter layer which have better dust holding capacity.
