According to recent studies, the same amount of dust that forms on the screen will form on a grounded metal plate (simulating a user) when placed a few feet from the TV / Monitor. The UltraStat FST for Computers and ClearView for Televisions has been laboratory tested and endorsed by optometrists and allergists worldwide. The following excerpt is compliments of Wolfson Electrostatics (UK): It is well known that electrostatic forces can be used to precipitate airborne dust particles from the atmosphere and an example of this precipitation effect can be found in almost every home. Television sets generate high voltages which set up an electric field between the TV set and surrounding surfaces. This electric field influences dust particles in the air and tends to deposit them on the screen, the TV housing and any nearby surfaces. It is quite common for a very fine layer of dust to accumulate on the screen of a TV after it has been switched on for a few hours. If this dust were analyzed it would almost certainly contain fragments of dust mite fecal pellets - a material, which has been identified as one of the main asthma allergen carriers.
