We get so sick of our forced air furnace. We keep the heat ducks cleaned out where we can reach them with the vacuum cleaner. Then my husband at least once a year has a duct cleaning company come in and suck all the pipes out. But still you can see the dust on the air as the sun comes through the window. We decided to go with a new high tech HAVC filter. It's amazing. It traps the particles with the static charge built into it. I don't know exactly how this works but I know it works good.
