1. A filter cartridge comprising:
a) a filtration media arrangement extending along a longitudinal axis between a first end and a second end and defining an interior volume;
b) a support tube operatively coupled to the filtration media arrangement;
c) a biasing spring for biasing the filter cartridge in a first direction opposite an insertion direction of the filter cartridge, wherein the biasing spring is located at least partially within the interior volume; and
d) a first part of a connection arrangement for connecting the filter cartridge to a structure including a second part of the connection arrangement, the first part being at least partially defined by the support tube and including a plurality of spaced apart, circumferentially arranged latches, the latches being deflectable in a direction toward or away from the longitudinal axis.
 
11. An air cleaner assembly comprising:
a) a housing including a housing body and a housing cover, the housing body and housing cover defining an interior volume;
b) a filter cartridge being disposed within the housing, the filter cartridge including:
i) a filtration media arrangement extending along a longitudinal axis between a first end and a second end;
ii) a support operatively coupled to the filtration media arrangement; and
iii) a first part of a first connection arrangement for connecting the filter cartridge to a structure including a second part of the first connection arrangement, the first part being at least partially defined by the support and including a plurality of spaced apart, circumferentially arranged latches, the latches being deflectable in a direction toward or away from the longitudinal axis;
c) wherein the first part of the first connection arrangement is secured to the second part of the first connection arrangement such that the filter cartridge is secured to the housing body; and
d) a second connection arrangement securing the filter cartridge to the housing cover such that the housing body and the housing cover are secured together, the second connection arrangement including a handle rotatably secured to the housing cover, wherein rotation of the handle in a first direction secures the filter cartridge to the housing cover and rotation of the handle in a second direction disconnects the filter cartridge from the housing cover.
