Extra filter in duct
Ok dumb question. Changing my AC filter today and noticed this extra carbon looking filter screwed to the side of the duct above the regular filter. What is it and why is it there? Something to make the air smell better?

Return air vents
can I put my return air vents that are panned in joist of kitchen flooring, underneath my island? I was told I can cut hole under island and add vents at base? So is there no need to move panning running in joists?
