Review on Enhance Performance with Hoover Bagless Backpack Vacuum C2401 Filter by Cynthia Chacon

Not original, did not filter like the old one before it became obsolete. When I press the vacuum cleaner, dust / smell appears at the beginning and every time after turning off and on. I'm considering replacing the cloth pouch but I'm afraid that won't help as it seems the stitching point could fail more easily. If any of you figured out/saved the Hepa function please let me know what worked.
