Shark sells foam-and-felt kits under different OEM numbers. Match the full vacuum code and the pre-motor filter position before buying; a HEPA exhaust filter is a different part.
Source-checked foam and felt kits
| Kit | Representative listed model | Buying distinction |
|---|---|---|
| XFF350 | CU500 | Foam-and-felt pre-motor kit for listed Navigator-family codes; compare the full NV suffix and do not substitute an exhaust HEPA filter. |
| XFF450 | NV200 | Foam-and-felt kit for the official NV200/NV450-family list; compare its specific model set with XHF450. |
| XFF650 | AX950 | Foam-and-felt kit for listed AX950/AZ1000-related codes; XHF650 is a separate HEPA entry with a different source list. |
| XFFK320 | LA300 | Foam-and-felt kit for exact LA300/LA500/QU360-related codes; a separate XHF320 HEPA filter serves the exhaust side. |
| 617FJ140 | IX140 | Pre-motor foam-and-felt kit for listed IX, IZ, and related exact codes; 616FJ140 is a different post-motor filter. |
| 1239FT60 | CU50WM | Foam-and-felt kit for exact NV150/NV250/ZU-series codes; Shark labels both pieces rinseable and reusable. |
Can these filters be washed?
Shark explicitly calls the two pieces in kit 1239FT60 rinseable and reusable. Do not carry that care instruction over to another kit or HEPA cartridge without that product’s manual. Let any washed filter dry as the maker instructs before reinstalling it.
If your machine has both foam/felt and HEPA filters, identify which position needs service. A model can appear on both source lists without the filters being substitutes.
Check before ordering
- Find the complete model code on the machine.
- Identify the original filter position and shape.
- Open the specific Shark product listing and check your full code, including suffix letters.
