Filter arrangements; side-entry housings; and methods

An air cleaner comprising:

• (a) a housing having first and second opposite ends and a sidewall between said first and second ends;
• said sidewall defining an access opening;
• said sidewall having a slide mount;
• an access cover removably positioned over the access opening;
• (b) a filter element operably installed and sealed in the housing;
• the filter element having first and second opposite flow faces;
• the filter element including media having a plurality of flutes;
• each of the flutes having an upstream portion adjacent to the first flow face and a downstream portion adjacent to the second flow face;
• selected ones of the flutes being open at the upstream portion and closed at the downstream portion;
• and selected ones of said flutes being closed at the upstream portion and open at the downstream portion;
• (i) said housing being constructed and arranged to accept the filter element through the access opening in the sidewall and slide along the slide mount;
• (c) said sidewall defining a bump out region;
• (i) said housing being constructed and arranged to accept the filter element through the access opening in the sidewall, slide along the slide mount, and engage the bump out region;
• and p1 (d) the housing including a pivot region about which the filter element can pivot when moving into and out of sealing engagement with the housing.

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 first and second opposite flow faces;
• the filter element including media having a plurality of flutes;
• each of the flutes having an upstream portion adjacent to the first flow face and a downstream portion adjacent to the second flow face;
• selected ones of the flutes being open at the upstream portion and closed at the downstream portion;
• and selected ones of the flutes being closed at the upstream portion and open at the downstream portion;
• 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 pivot 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 bump out region in 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 including first and second opposite flow faces, media having a plurality of flutes;
• each of the flutes having an upstream portion adjacent to the first flow face and a downstream portion adjacent to the second flow face;
• selected ones of the flutes being open at the upstream portion and closed at the downstream portion;
• and selected ones of the flutes being closed at the upstream portion and open at the downstream portion;
• 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 bump out region;
• (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 pivoting the element about the pivot region to move the seal member into sealing engagement with the housing.
