Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.
