I have a Dyson Animal 2 (DC65) and they fit great. My Dyson had an immediate improvement in suction power with the new filter. (I haven't been able to clean Dyson filters in years.) Pros: They look and feel the same as genuine Dyson filters. 3 HEPA filters and 3 pre-filters. because I cleaned my DC65 thoroughly during installation. No cons yet, but I'll update this review if I run into any issues. The photos show the old filters versus the new filters, the new pre-filter on the sphere and everything that was in the box. .If this review was helpful, please click the button below. Happy buyer.
