To provide a health promoting apparatus comprises a device which generates air negative ions by means of water to settle the problem of exposure to toxic substances and radioactive rays, and a container which utilizes air negative ions efficiently.

Air negative ions is emitted intensively into a small space and pressurized so that intakes of the air negative ions are increased, by using a negative ions generator of a simple mechanism to generate fog by an ultrasonic oscillator in which an electric conductivity of the water used is regulated at less than 10 S/cm, and a container composed of processed cylindrical pipe having a door which can be opened and closed.
