A filtering device (10,30,54,70) for use with a register (52,56,110) in a forced air climate control system (50) primarily includes a filter substrate (12,32) and an adhesive layer (14,34). The filter substrate (12,32) filters particulate matter from air flowing through it. The adhesive layer (14,34) is disposed in a discontinuous pattern on the filter substrate (12,32) to permit removable attachment of the filter substrate (12,32) to the register (52,56,110) while simultaneously allowing air to bypass the filter substrate (12,32) when the filter substrate (12,32) becomes substantially saturated with the particulate matter. |
