TITLE EXPANDABLE MULTI-PLY OBLIQUELY ORIENTED HONEYCOMB FILTER MEDIA APPLICANT HONEYCOMB CONSTRUCTION SERVICES LTD. INVENTORS Victor Vernon SPENCER (deceased) c/o his executrix Mary Spencer - and - Leonid Andreevich BAGRIN ABSTRACT A multi-ply expandable filter media formed of obliquely oriented honeycomb organized into a ply or run having expandable honeycomb cells with one run oriented at, preferably an acute angle, of 30° to 60° relative to the cells of an adjacent run. Preferably, the respective plys or runs are arranged in relative parallel planes defining a planar space therebetween. There is provided means for collapsing the filter media into a closed compressed, transportable state, and when ready for use as a filter media, to allow the same to be expanded and pulled open and to be constrained in an preselected, open, expanded position so that the cross sectional area of each cell is thereby substantially increased. In this manner, the juxtaposed, open plys allow directional change for airflow flowing through the filter media, encouraging deposits of air-borne material to become attached to the wall surfaces of the family of cells of each run or ply. To enhance adhesion, an adhesive may be sprayed over the cell walls.
