Dyson no longer make these filters, however we are able to offer these great after-market alternatives. These will fit all versions of the DC01 vacuums. 

The filter locations for these on your machine is one in the yellow cage down the side of the motor and the other sits above the motor. Now if you have a HEPA machine then the filter above the motor will be a purple plastic one, we do stock and sell that filter and it can be found below.

Or if you want to save money we also sell it as a kit, again this can be found below
