Changing Furnace Air Filter?

I live in a mobile home and have a Coleman heat and air unit; it is all electric. My home is very dusty, yet every time I change the filter there's not a speck of dust on it.

Your furnace filter will only catch dust that is easily airborne. Most dust is too heavy to make it up to a furnace filter and just settles on the floor, furniture, etc. Your couch and upholstered chairs become very dusty as people often do not realize their couches, beds, etc., are huge dust collectors. They do not vacuum their furniture as they do not "see" the dust. Then, when people sit down on couches, beds, etc., dust from the furniture will rise in billowing clouds and will then settle on surrounding furniture and floors.

I don't think your fan is working properly. Is it heating well? My filters are always covered with dust, and the fan itself will get clogged with it.


Turn your furnace off and check to see if the fan is clogged.
