Some Fords do and some don't :P On my model (Taurus) there is a area on the hvac box there where it looks like one should be but never had one so I carefully cut out the rectangle and put one in then sealed with foil tape over the cutout. In your case I would just leave well enough alone unless you really want one or there is a actual space like mine to install a filter. Good Luck!
According to my owners/service manual, the 1999 ford expedition for that year model did not install cabin air filters
