Shark HEPA Replacement Filters: Match the Exact Model

Compare source-checked Shark HEPA filter numbers XHFZU55 and XHFAZ4000.

HEPA is a filter designation, not a fit guarantee. Shark lists XHFZU55 for ZU55 and XHFAZ4000 for AZ4000, AZ4002, and AZ4002W.

Do not shop by “HEPA” alone

Find the complete model code on your vacuum. A shared filtration label does not mean the cartridges, seals, or housings are interchangeable.

Before ordering

Match the printed OEM filter number if available, then open the relevant manufacturer listing. Follow that model’s cleaning and replacement directions rather than assuming all HEPA filters are washable.
