The filters on the Dyson V10 and V11 are not completely interchangeable. 
While they may be similar in some ways, since the V10 and V11 are different 
models of vacuum cleaners, their designs may differ slightly, including the shape,
size and attachment of the filters. Therefore, I recommend that you better use 
the correct filter designed for your specific vacuum cleaner model to ensure optimal 
performance and a proper installation. If you have any questions it is best to consult
 Dyson directly or consult the relevant user manual or guide.
