Wipe the screen(even better have someone you dislike do it and leave the room/ j/k).
Alpha particles love tv screens.
You don't want to smoke alpha particles.
i remember as a child we used to play next to the TV screen and the ladies with long hair were attracted creating a funny look! If it attracted hairs i think it can attract also stalks...
You don't want to smoke anything attracted by the screen, i suggested to use it just to create the "force". You have to put a micron screen over it at a determined height wich will keep clean heads but let go dust under. Maybe you also need to electric charge the particles you are sifting to make it work, not sure. Maybe all of this is pure fiction...i am just thinking at high voice...
sorry if i am on a wrong path...
