Charged water particle, and method for creating environment where mist of charged water particle is dispersed

A method of creating an environment where a mist of charged fine particulate water is dispersed, said method comprising the steps of:

• providing a pair of electrodes, water supply unit configured to supply water between said electrodes, and a voltage applying unit configured to apply a voltage between said electrodes;
• generating said mist of charged fine particulate water having a particle size of 3 to 100 nm and containing radicals by applying a high voltage between said electrodes, while supplying water between said electrodes by said water supply unit;
• and
• supplying said mist into a desired space to create the environment where said mist of charged fine particulate water is dispersed in the desired space.
