My own fault for skimming the filter description. These aren't genuine Dyson filters but aftermarket ones. I'm sure they will do the job fine however the one I recieved had a couple extra tabs that had to be cut off to fit my DC25 vacuum. Shipping was fast as always. *********McHardy Response: Sorry to hear you had to modify Jim. This is the first complaint of tabs of many we sell. We just looked at our current stock and there are no extra tabs. These are designed to fit the Dyson DC25 & DC29 Models.
