Static electricity is generated through photocopiers and electrostatic precipitators. An electrostatic precipitator removes fine particles like dust and smoke from gas by charging the particles electrostatically without slowing the flow of gas. Inkjet printers also use static electricity to spray ink droplets onto paper.

• An electrostatic precipitator is a filter less device that removes fine
particles, like dust and smoke, from a flowing gas using the force of an
induced electrostatic charge minimally impeding the flow of gases
through the unit.
