Claim 8:
9. A method of installing a filter into a filter-receiving receptacle of an air conditioner of a vehicle, the method comprising:
removing an existing filter from the filter-receiving receptacle;
forming a body entirely of air-transmissive open-cell polymeric material having a plurality of cubical members frangibly connected together, the step of forming comprising:
cutting slits entirely through the body such that the plurality of cubical members are frangibly connected together, the cut slits extending lengthwise across the body and widthwise across the body so as to form the plurality of cubical members;

hand separating some of the plurality of cubical members from a remainder of the body until the body is of a size no less than the size of the existing filter such that an individual cubical member of the plurality of cubical members is separable along both of a portion of a length and a portion of a width of said body; and
inserting the body with the size no less than the size of the existing filter into the filter-receiving receptacle of the air conditioner of the vehicle.
