We all hate it when you realize that haze you got used to is actually a nice layer of dust stuck to the surface of your CRT television. The status charge left behind on the surface of the screen attracts dust right out of the air. Unless you can remove the dust from the air, or prevent the static from lingering, there's not much you can do to thwart the dust .

Hepa air filters go a long way to removing most of the dust in the air, but you're just delaying the inevitable with this solution. Sure, it'll take a longer time before the dust returns in any quantity to annoy you, it'll happen none the less. There's currently no way to remove the static charge from surface of the tube, so unless you're going to watch television from inside a clean room, I'm afraid you'll have to deal with wiping the screen down every now and again.
