This is the Shark Foam and Felt Filter Kit, SharkNinja model XFF36, for Navigator upright vacuums. It replaces the pre-motor filters that sit under the dust cup, which are the filters that clog first and the usual cause of a Navigator that has lost suction or started to smell. The foam filters are washable and reusable, so the kit is worth keeping on hand as a spare set to run while the originals dry.

Fits
SharkNinja lists compatibility for XFF36 as NV36, NV36A, NV42, NV44, NV46 and NV46C. Distributors list additional Navigator models, but those are not on the manufacturer's list, so we publish only the models SharkNinja states. Confirm fitment against your machine's model number before ordering.
SharkNinja publishes no wash or replacement interval for this kit and does not describe it as a HEPA filter, so we make neither claim. Resellers quote intervals that disagree with each other. As a practical matter, rinse the foam filters when airflow drops and allow them to dry completely before refitting. Discount Cleaning Products is a US-based dealer stocking Shark filters and accessories.
