An electrostatic precipitator (ESP) is a piece of equipment that uses high DC voltage to deposit a charge on precipitates passing through it, and a charge of opposite polarity on collector plates that attract and hold the precipitates. The whole process produces an outflow of air or gas that has far less particulate matter in it.

Devices like the ESP are used in different environments to clean air, and are also applied to clean the flue gases coming out of boilers to remove flyash.
