The Shark Foam & Felt Filter Kit for Shark Navigator Lift-Away Vacuums is a replacement filter set designed to maintain strong suction and optimal air quality in compatible Shark upright models. This kit replaces part #XFF350 and includes both a foam and felt filter, working together to capture dust, debris, and allergens before they reach the motor or recirculate into your home.

Constructed from durable, high-quality filtration materials, the foam and felt filters are engineered to trap fine particles such as dust, pollen, and pet dander. The custom-fit design allows the filters to install without trimming or modification. Both filters are washable and reusable—simply rinse with water, allow them to air dry completely, and reinstall for continued performance.

This filter kit is compatible with a wide range of Shark Navigator Lift-Away upright and professional models, including the NV350, NV351, NV352, NV355, NV356, NV360, NV370, UV440, UV540, and many additional variants. Regular cleaning every 1–2 months and replacement every 2–3 months (depending on usage) helps maintain peak suction power and extends the life of your vacuum.
