Most box fans are not designed to have enough oomph for something like a Filtrete filter. They are only rated for about an inch of pressure.
Electrostatic filter on the furnace/AC is a good step. A multi speed HEPA unit advertised for a large family room is what I would put in a sufferers bedroom. Consumers Reports is one of the few places that has ratings for noise, about all I would look for in a recommendation of filter units.
