Cheap fake. The foam is made from a cheap material that may not even filter dust particles like the OEM version to reduce density. The quality of the cut goes through terrible quality control. See image. Also, the HEPA filter is poor quality and literally folded paper. A picture is also attached. Going forward, I'll stick with the Shark brand because I don't want dust flying around when vacuuming. This is one of their main advantages.
