Review on Anewise 4-Pack Washable Pre-Filter Set Compatible with Dyson Vacuum Cleaners DC30, DC31, DC34, DC35, DC44 Digital Slim, DC56 | Replaces Dyson Pre-Filter Part # 917066-02 by Tricia Smith

I read the reviews on this product and decided to give it a try as my DC-44 filter is showing its age. Like other reviewers, I can say that the filters are flat and feel a little thick, making it difficult to initially install and then close the unit. After that, it's easier to uninstall and reinstall. What has disappointed me is that I notice a lot more odors when using Dyson after installing these generic filters than when using an OEM filter. I no longer see dust coming through this filter, but I notice more odors even when the filter is first installed.
