This was on a Dyson DC-14 floorstanding unit. I paid close to $500 a few years ago and prefer to repair rather than replace. Received very promptly. It took me less than 10 minutes from unpacking to installation. Pay attention to the size of the filters. In my vacuum they are perfect. The quality isn't Dyson quality, but if that's what you want, be prepared to shell out a little more for it. I've replaced both filters and while some have complained about the loss of suction, I haven't noticed anything of the sort. Two rubber spacers are supplied with double-sided tape and used on the bottom of the purple filter.
