Abstract
A filter box mounts to an air intake opening of an air handler. The filter box includes an inner shell, insulator, and an outer shell. The inner shell is adapted to confine one or more filters therein. The inner shell defines an airflow channel from a front end opening of the inner shell through the filter(s) to a rear end opening of the inner shell. The outer shell defines a chamber from a front end opening of the outer shell to a rear end opening of the outer shell. The outer shell contains the inner shell in the chamber and the insulator is sandwiched between the outer shell and the inner shell. The inner shell and the outer shell are separated and spaced apart all over by the insulator and the insulator insulates and seals the inner shell from the outer shell.
Claims15
A filter box adapted for mounting to an air intake opening of an air handler, the filter box is adapted to receive at least one filter therein, the filter box comprising:
- an inner shell adapted to confine the at least one filter therein, the inner shell defining an airflow channel from a front end opening of the inner shell through the at least one filter to a rear end opening of the inner shell;
- an insulator;
- and
- an outer shell defining a chamber from a front end opening of the outer shell to a rear end opening of the outer shell, wherein
- the outer shell contains the inner shell in the chamber and the insulator is sandwiched between the outer shell and the inner shell,
- the inner shell and the outer shell are separated and spaced apart all over by the insulator and the insulator insulates and seals the inner shell from the outer shell.
A method of insulating a filter box for an air handler, comprising:
- providing an inner shell adapted to confine at least one filter therein, the inner shell defining an airflow channel from a front end opening of the inner shell through the at least one filter to a rear end opening of the inner shell;
- disposing an insulator on the inner shell;
- installing around the insulated inner shell, a front outer half-shell and a rear outer half-shell to form an outer shell that defines a chamber from a front end opening of the outer shell to a rear end opening of the outer shell, the outer shell contains the insulated inner shell in the chamber and the insulator is sandwiched between the outer shell and the inner shell, the inner shell and the outer shell are separated and spaced apart all over by the insulator;
- and
- affixing together the front outer half-shell and the rear outer half-shell around the insulated inner shell to form the filter box, the insulator is compressed between the outer shell and the inner shell and insulates and seals the inner shell from the outer shell.
