- Shark lists XHF350 as the HEPA filter and recommends replacing it every 3 years on the product page.
How to check your vacuum model
Before ordering, compare the machine model number, product label, series or variant, and existing filter design with the manufacturer source. If the exact relationship cannot be confirmed, treat it as unverified.
- Read the complete NV, UV, CU or ZU model code from the rating label.
- Compare the exact code with the XFF350 and XHF350 lists separately.
- If your suffix is not listed, do not infer compatibility from the Navigator name alone.
Frequently asked questions
Can I use a similar-looking filter?
Only if the manufacturer source lists your exact model or configuration. Shape alone is not a compatibility check.
Does this page cover every regional variant?
No. This page is based on U.S. manufacturer information and only claims the variants shown in its compatibility table.
What if my model is not listed?
Use the linked manufacturer source to check the exact model. Do not infer compatibility from a nearby model name or marketplace listing.
