Kenmore CF-2 Upright Door F...

Product details
CF-2 is the foam filter that sits in the door of a Kenmore upright, and this two-pack, part 910, replaces it. Two is the right number to own: one goes in the machine while the other dries after a wash.
Foam of this kind is washable up to a point. Rinse it warm, squeeze rather than wring, and let it dry completely before it goes back - fitting a damp filter is how a vacuum ends up smelling of mildew. After enough cycles the foam compresses and stops springing back, and at that point it is restricting air rather than filtering it.
The signs of a tired door filter are familiar enough: suction that fades over a few weeks, a motor that sounds like it is straining, and dust showing on the exhaust side. A fresh one takes seconds to fit.
