OP, try this along with regular cleaning as others have mentioned. The secret with the box fan/filter setup is that it can move a lot more air than most air filter systems. I run mine on a higher speed setting when I am not in the room/home, and turn it way down or off when I am using the room. Some filters are specifically rated to remove pollen, mold, etc. but they cost more.
