You take pride in your home. You vacuum the floor, you dust the furniture, you wash the fingerprints off the walls. So where did that ugly black film around the supply air registers come from? In a new home it is usually a sign of extreme filter neglect (you know, no filter). In an older home it can be a sign of dirty air ducts caused by using an inefficient air filter. At any rate it is dirt, smoke, pollen, and dust that was not caught by the filter. You can wash it off but it will come back?
