Since most of the cleaners without filters with filters for air only brand), they clear only from large dirt particles. Small, passing through the "turbine" vacuum cleaner, only accelerated and fly up in the air.
Thus, even in a clean apartment on the beam of light is visible dust, flying in the air. To avoid this, I came up with the idea of using high voltage power supply as traps dust. Because much dust settles electric gun of the CRT TV.
The scheme of such device is shown in Fig. 1.
Due to my little knowledge I your idea outlined how "the game is not possible is worth the candle" - a device at high risk for life can be extremely "cost-effective".
But it's just an idea, maybe there is a person who will be able to develop my thought to another apparatus needed in the home, like a vacuum cleaner, etc., it will fit as an air ionizer.
