A filter arrangement includes a media construction comprising a corrugated sheet secured to a flat sheet rolled into a coiled construction. A frame and a first seal member are provided. The frame secures the first seal member to the coiled construction. The first seal member is preferably oriented to form a radial seal with a housing. A second seal member is secured to the outer annular surface of the coiled construction. The second seal member includes a gasket extension having first and second opposite ends; an attachment portion; and a protrusion extending from the attachment portion. The second seal member is preferably oriented to form an axial seal with a housing. Air cleaners preferably utilizing filter arrangements as described herein operably installed within housings. Methods of installing, filtering, assembling, and servicing preferably include arrangements as described herein.

Latch arrangements for mounting on a first housing section to secure the first housing section to a second housing section are provided. The arrangements are particularly well adapted for utilization with air cleaner housings. Several designs described comprise bent wire arrangements having a first handle segment formed from a single piece of bent wire, and a latch or hook segment formed from a second piece of bent wire. Preferred configurations for utilization with plastic housing sections, are provided. An alternate latch arrangement, comprising a single molded latch member, is also provided.
