Does my vehicle have a cabin air flow filter?

if it's got one,drop the glove box door down..it will be behind it,IF there is one. even though the parts stores may list one(maybe) it still may not have come equipped with one! i personally don't believe it has one. does the A/C blow harder out the defrost when selected or the floor when selected? or does it blow about the same as the panel/face vents?
