Dirt Devil Type F77 for Stick Vacuum Cleaner Filter Part 440003993
We had been looking for this Dirt Devil filter for a year. Even Dirt Devil didn't have it in stock. We considered even buying a new small vacuum for our camper because we couldn't find the filter. And Red Vacuum had it! Shipping was free and quick. SO excited to get exactly what we needed and it allowed us to keep our current vacuum. Kudos!!
