Shark XFF350 / XHF350 HEPA Filter Compatibility Finder
If your Shark vacuum’s model number is one of a dozen different codes — NV350 through NV391, or UV440/490/540 — they all take the exact same HEPA filter kit: the XFF350 (sometimes labeled XHF350). This page cross-references every model that uses it, so you don’t have to guess from a confusing parts list.
Which Shark Models Use the XFF350?
| Shark Model Numbers | Filter |
|---|---|
| NV350, NV351, NV352, NV355, NV356, NV357, NV360, NV370, NV391, UV440, UV490, UV540 | XFF350 / XHF350 HEPA Filter Kit |
These span Shark’s Navigator Lift-Away and UV Series upright models. If your vacuum’s model plate shows any of the codes above, this is your filter — no need to match by name variant (Lift-Away, Zero-M, Pro, etc.), the model number is what determines fit. (Confirmed against SharkNinja’s official XFF350 product page.)
How Do You Maintain the XFF350?
This is a washable filter, not a disposable cartridge. Rinse it monthly under cold water (no soap or detergent) and let it air-dry fully for at least 24 hours before reinstalling — a damp filter reinstalled too early is the most common cause of a musty smell or motor strain. Even with regular rinsing, replace the filter kit every 3 months, since the foam and felt media lose filtration efficiency over time even when they still look clean.

Frequently Asked Questions
Is XFF350 the same as XHF350?
Yes — XFF350 and XHF350 are the same filter kit under two labeling conventions Shark has used across product runs. Either code will fit the models listed above.
How often should I replace my XFF350?
Rinse monthly, but replace the kit entirely every 3 months regardless of appearance — foam and felt media degrade even when visibly clean.
Can I put the XFF350 in the washing machine or dryer?
No. Hand-rinse only with cold water, no soap. Machine washing and drying can damage the foam and felt media or leave detergent residue that affects suction.
