I've had a Dyson DC-14 for 12 years and have never changed the filters (oops) so thought I'd try these spares first before buying any Dyson branded products. They fit perfectly and the suction power on my Dyson is amazing again! This kit includes a black ring for the bottom of the filter and you will definitely need it for the filter to work properly. I would recommend and buy again if needed. My Dyson is 12 years old!
