It's the same exact HyperHEPA just without the cosmetic blue membrane that was on the top and bottom of the filter - same specifications, dimensions, and performance standards as the previous version. Upon receipt you'll notice a "new look" sticker on the top of the box that the HyperHEPA is packaged in. New look meaning that without the cosmetic blue membrane on the top and bottom of the filter the white interior pleated HEPA material is now visible, making it look very similar to the PreMax Prefilter. If you have any doubts or concerns we strongly encourage you to contact IQAir's Technical Support department directly at 888-560-1020 for verification.
