Electrospray was combined with an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with sizes ranging from 10 to 300 μm. The combination of the ESP with the electrospray enhanced collection of particles by 21–36% depending on the particle size. The combination of the ESP and the electrospray was also found to reduce the energy consumption of the ESP.
