Shark Rotator Pro Lift-Away NV500 NV500CO NV500W NV501 NV502 NV503 NV505 NV510 NV520 NV550 NV552 UV560 NV642 HEPA Filter & 2 Foam & Felt Filter Kits, Part # XHF500 & XFF500

Didn't come in box like pictured, sent in a bag so there was compacting. Once unpackaged and fluffed up to near original shape the size was 3” in diameter, same as my original one in my Shark NV501. The little pre filter it comes with had good thickness to it. Overall Im happy with my order and the quality. For this price i can replace them every few years. I purchased these over other knockoff brands because a lot of other brands had reviewers complaining the foam filter was too narrow or short. These ones were true to the original size my Shark came with so I feel I made a great but.
