Thanks, but there is no door on this unit. I know what you mean
though...my old furnace had a door on the compartment that housed the
blower and filter.

On my new unit, the filter just slips into a slot in the ductwork just
before the blower. If any basement air is going to be sucked into the
system via the filter opening, it's already happening.

Do you have a humidifier on this furnace?
