Dyson's V8 name spans different pre-filter and battery configurations. Its own spare-parts chooser separates star pre-filter machines from pinch pre-filter/E-battery machines before recommending components. This catalog records 967478-05 only as a conditional V8 star-variant post-filter; it does not treat a generic V8 search as an exact model match.
How to avoid a wrong part
Start with Dyson's machine or serial-number identification flow and compare the physical filter shape. The star-variant parts page and the pinch/E-battery route are separate sources. Keep the confirmed variant when you move from a filter question to a battery or charger question.
Identify your exact variant
The maker names a variant but the current source does not resolve a complete machine code for a standalone model page. Use the official identification flow before buying.
