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.

1. A method of installing a filter element into an air cleaner; the method comprising:(a) providing a filter element having a media construction comprising a media construction having a plurality of flutes, a first end, an opposite second end, and a first seal member oriented adjacent to the first end; (i) the plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at portions adjacent to said first end and closed at portions adjacent to said second end; and said outlet flutes being closed at portions adjacent to said first end and open at portions adjacent to said second end; (b) inserting the filter element into a housing body until a radial seal is formed between a radially directed seal member oriented adjacent to the second end of the filter element and the housing body; and (c) after said step of inserting, orienting a cover over the filter element and forming an axial seal by squeezing the first seal member between the cover and the housing body. 2. A method according to claim 1 wherein:(a) said step of providing a filter element includes providing a filter element wherein the first seal member includes a gasket extension having first and second opposite ends; an attachment portion; and a protrusion extending from the attachment portion; (i) the attachment portion including an attachment surface securing the gasket extension to an outer annular surface of said media construction; and (ii) the protrusion including first and second inclines and a land therebetween; and (b) said step of forming an axial seal includes squeezing the protrusion between the cover and the housing body. 3. A method according to claim 1 wherein:(a) said step of providing a filter element includes providing a filter element including a frame and the radially directed seal member; the frame securing the radially directed seal member to the media construction; the frame having a skirt and an axial extension; (i) the skirt circumscribing and securing the frame to the media construction; (ii) the axial extension projecting axially from the second end of the media construction; the axial extension having an annular portion; (iii) the annular portion of the axial extension supporting the radially directed seal member; and (b) said step of inserting the filter element into a housing body until a radial seal is formed includes forming a radial seal by compressing the radially directed seal member between and against the annular portion of the axial extension and the housing body. 4. A method according to claim 1 wherein:(a) said step of providing a filter element includes providing a filter element including a media construction comprising a corrugated sheet secured to a flat sheet rolled into a coiled construction; the coiled construction being rolled around a core construction. 5. A method according to claim 4 wherein:(a) said step of providing a filter element includes providing a filter element including a frame and the radially directed seal member; the frame securing the radially directed seal member to the media construction; the frame having a skirt and an axial extension; (i) the skirt circumscribing and securing the frame to the media construction; (ii) the axial extension projecting axially from the second end of the media construction; the axial extension having an annular portion; (iii) the annular portion of the axial extension supporting the radially directed seal member; (iv) the core construction having a first end; including a pair of deflectable flanges; (A) the core construction being releasably secured to the frame. 6. A filter arrangement comprising:(a) a media construction comprising a plurality of flutes, a first end, and an opposite second end; (i) said plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at a portion adjacent to said first end and closed at a portion adjacent to said second end; and said outlet flutes being closed at a portion adjacent to said first end and open at a portion adjacent to said second end; (b) a frame secured to said media construction; said frame having an axial extension; (i) said axial extension projecting axially from said second end of said media construction; (c) a first seal member secured to said axial extension; and (d) a second seal member secured adjacent to the first end of said media construction. 7. A filter arrangement according to claim 6 wherein:(a) said frame includes a skirt secured to the media construction. 8. A filter arrangement according to claim 7 wherein:(a) said skirt circumscribes and secures said frame to said media construction. 9. A filter arrangement according to claim 6 wherein:(a) said media construction comprises a corrugated sheet secured to a flat sheet rolled into a coiled construction. 10. A filter arrangement according to claim 9 further including:(a) a center piece construction; said coiled construction being mounted on said center piece construction. 11. A filter arrangement according to claim 10 wherein:(a) said center piece construction includes a tube including a pair of deflectable flanges; (b) said tube being releasably secured to said frame; (i) said pair of deflectable flanges engaging a portion of said frame. 12. A filter arrangement according to claim 6 wherein:(a) said second seal member is secured to an outer annular surface of said media construction. 13. A filter arrangement according to claim 6 wherein:(a) said second seal member includes a gasket extension having first and second opposite ends; an attachment portion; and a protrusion extending from the attachment portion; (i) said attachment portion including an attachment surface securing said gasket extension to said media construction; (ii) said protrusion including first and second inclines and a land therebetween; and (iii) said gasket extension further includes a first ramp and a second ramp; said first ramp being opposite of the attachment surface; said first ramp extending from said first end to said protrusion; second ramp extending from said second incline to said second end. 14. A filter arrangement according to claim 13 wherein:(a) said attachment portion is secured to an outer annular surface of said media construction. 15. An air cleaner comprising:(a) a housing including a body member and a cover; said body member defining an interior; (b) a filter element operably installed within said body member interior; said filter element including: (i) a media construction comprising a plurality of flutes, a first end, and an opposite second end; said plurality of flutes comprising inlet flutes and outlet flutes; (A) said inlet flutes being open at a portion adjacent to said first end and closed at a portion adjacent to said second end; and said outlet flutes being closed at a portion adjacent to said first end and open at a portion adjacent to said second end; (ii) a frame secured to said media construction; said frame having an axial extension; (A) said axial extension projecting axially from said second end of said media construction; (iii) a first seal member secured to said axial extension; (A) said first seal member oriented in a radial direction to form a radial seal with said housing; and (iv) a second seal member secured to the filter element; (A) said second seal member being squeezed between said cover and said body member to form an axial seal therebetween. 16. An air cleaner according to claim 15 wherein:(a) said second seal member includes a gasket extension having a protrusion; (i) said protrusion being squeezed between said cover and said body member to form said axial seal. 17.
