(ii) a second surface opposite from the first surface and defining at least one inwardly projecting section and, at least one outwardly projecting section;

(iii) at least one of the first and second surfaces comprising a housing seal surface.

2. An air filter cartridge according to claim 1 wherein:

(a) the first radially outer surface defines: at least three outwardly projecting sections; and, at least two recesses, one between each adjacent two outwardly projecting sections of the at least three outwardly projecting sections.

3. An air filter cartridge according to claim 2 wherein:

(a) the media defines a non-circular outer perimeter.

4. An air filter cartridge according to claim 3 wherein:

(a) the media defines an oval outer perimeter.
