Abstract (en)
An air ionization device for generating negative ions comprises an electrode (14), and a circuit including a transformer (5) and voltage-doubler rectifier circuits (7,8) for producing from a relatively low voltage source (1,2) a negative voltage for application to said electrode (14) of sufficient magnitude to cause a corona discharge and produce negative ions at said electrode (14), said electrode (14) being formed of carbon fibre filaments (16).
