Review on Premium Replacement HEPA + 2 Foam Filter Kit F44 for Dirt Devil Vacuum Cleaners (304019001 Compatible). Fits: UD20015, UD20100, UD20020, UD20025 by Sandra Ford

They fit my vacuum cleaner perfectly. I didn't realize they needed to be changed from time to time and they make a huge difference in suction! It's pretty quick and easy to take out and clean the foam insert (I just run it under hot water and wipe it off). remove it yourself if necessary to remove visible dirt). Do this as needed and the filter will last much longer. You can also take the filter out and tap the sink to wash off some of the dirt that's passed through the filter: However, if you're dumping a lot of dirt, it probably means you're not cleaning the foam insert as often as you could (which extends the life of the filter). I usually hate "maintenance" like cleaning the foam insert, but it's easy, the filter lasts a lot longer and gives back the strong suction your vacuum should have.
