Product review (1 stars): Bait and switch...
My original Essick Air filters were pleated much as shown in the picture of this item.  With Essick Air in the name I thought I would receive Essick-branded filters.  What I received was an off-brand filter that is an odd weave or crosshatch of material...not pleated.  In short, this was a bait and switch.  Do not buy if you want an original filter.
