Filter arrangements; side-entry housings; and methods

A method of servicing an air cleaner;

• the air cleaner including:
• a housing having first and second opposite ends and a sidewall between the first and second ends;
• the sidewall defining an access opening;
• an access cover removably positioned over the access opening;
• and a filter element operably installed and sealed in the housing;
• the filter element having a media pack and a sealing system, wherein the media pack has a first end and a second, opposite end and comprises filter media configured to provide flutes extending in a direction from the media pack first end to the media pack second, opposite end, wherein the media pack is closed to the flow of unfiltered air into the media pack first end and out the media pack second end, and wherein the media pack is closed to the flow of unfiltered air into the media pack second end and out the media pack first end;
• the sealing system comprises a seal member, the seal member having a perimeter shape defined by a pair of sides joined by curved ends;
• the housing being constructed and arranged to accept the filter element through the access opening in the sidewall;
• the method comprising:
• (a) pushing the filter element against a pivot region in the housing to tilt the filter element about the pivot region and release a seal between the filter element and the housing;
• and
• (b) after said step of pushing, removing the filter element through an opening in a side of the housing, and moving a portion of the filter element into a wedge-shaped area of volume defined by the sidewall.

A method of installing a filter element into an air cleaner;

• the air cleaner including:
• a housing having first and second opposite ends and a sidewall between the first and second ends;
• the sidewall defining an access opening;
• the sidewall defining a ramp;
• an access cover removably positioned over the access opening;
• the filter element having a media pack and a sealing system, wherein the media pack has a first end and a second, opposite end and comprises filter media configured to provide flutes extending in a direction from the media pack first end to the media pack second, opposite end, wherein the media pack is closed to the flow of unfiltered air into the media pack first end and out the media pack second end, and wherein the media pack is closed to the flow of unfiltered air into the media pack second end and out the media pack first end;
• the sealing system comprises a seal member, the seal member having a perimeter shape defined by a pair of sides joined by curved ends;
• the housing being constructed and arranged to accept the filter element through the access opening in the sidewall;
• the method comprising:
• (a) sliding the filter element along the ramp into a wedge-shaped area of volume defined by the sidewall;
• (b) contacting a seal member on the filter element against a pivot region on the housing;
• and
• (c) applying force to an exposed portion of the filter element and tilting the element about the pivot region to move the seal member into sealing engagement with the housing.
