ABSTRACT:
A nozzle is provided for use in a dynamic electrostatic air filter, in which the nozzle includes an internal electrode that charges a semiconductive liquid, and includes an external electrode that assists in breaking the liquid into droplets in a predetermined direction. Banks of multiple nozzles are also disclosed, which are separated by a charged “separation electrode” to prevent interference with spray patterns between adjacent banks. An electrostatic fountain is also disclosed which discharges a fragrance, or an inhalable medicine.
