It's indistinguishable from the filters that came with the new Shark. Size, appearance, construction, materials, etc. are identical. They are either perfectly remanufactured or they are OEM filters that have only been repackaged in aftermarket packaging. Either way, you won't be disappointed. I was amazed at how clogged the front HEPA filter was, even though it looked only slightly dusty. The particulate matter that passes through the primary foam filter is obviously so fine that it actually collects and clogs that filter. Airflow/suction is easily double what it was before the filter change. I've been driving with the original filters (with the foam and disc filters being flushed every few weeks) for at least 5 years so this package will probably last until the vacuum itself fails. money well spent.
