While dust will flow in through the air filters in your cooling system, dust also gets carried in by everyone who walks into the room. The dust accumulating on the floor, on the furniture, upholstery, and on us gets flown around and circulated. These eventually get accumulated in the air ducts. Not all of it, but a substantial amount.
Depending on where you live, or where your property is, the air filters may not be effective enough. Urban areas and industrial regions need much better filters than rural and agricultural areas. The more polluted an area, the stronger your air filters must be. Upgrade the filter or clean the filters regularly, keep your ducts clean, and try to keep your doors and windows shut when the air conditioner is not running.
