Shark Vacuum Filter Numbers Explained
The vacuum model number and the filter replacement number answer different questions: the first identifies the machine, while the second identifies a replacement item or kit. Record both exactly and confirm that an official source connects them.
Separate the identifiers
A product-family name can cover several machines. A package can also list many models while using its own stock or kit number. Do not assume that a number printed on an old aftermarket filter is the manufacturer’s official part number.
| Identifier | What it identifies |
|---|---|
| Vacuum model | The exact appliance configuration |
| Serial number | One individual appliance |
| Filter / kit number | A replacement item or set |
| Seller SKU | A retailer’s catalog entry |
Match the identity to evidence
Use an official manual, manufacturer parts page, or support document that connects the exact product model to an exact replacement identifier. Marketplace compatibility lists can help discover a candidate, but they should not replace manufacturer evidence.
Handle suffixes and revisions
Search the complete vacuum model first. A suffix can distinguish a revision, bundle, channel, or region, and similar family names may not share every filter stage. Accept a shortened family match only when documentation explicitly includes your complete model.

How this guide was prepared
Filter Fit separates compatibility evidence from purchase availability. Exact model identity, region, revision, and authoritative source scope are reviewed before a relationship is treated as verified.
