Filter is too small for full coverage
Filters are not the correct size, too small. Not worth the risk.
Brush arm bristles were also all bent up.

Filters are the wrong size for the Eufy C10 vacuum
The air filters are smaller than the stock air filter. They will probably work if they are stretched out a bit, but as delivered, are unacceptable. The roller and the sweeper are good. Poor filter fit. Original filter size: 1.75 inch by 3.65625 inch. The filters in this set are 1.25 inch by 3.5 inch. Too small.

Filters were not the right size!
While the roller brush and side brush are fine, the filters DID NOT fit properly, they were about 1/8 smaller on both dimensions than the original filter on my C10.
