An air cleaner is provided according to an embodiment of the invention. The air cleaner includes a power supply, an electrostatic precipitator cell, and a door. The door closes the electrostatic precipitator cell inside the air cleaner. The air cleaner further includes a door switch that is actuated by the door when the door is substantially closed. The air cleaner further includes a cell presence switch. The electrostatic precipitator cell actuates the cell presence switch when the electrostatic precipitator cell is at least partially inserted into the air cleaner. The cell presence switch and the door switch enable electrical power to be supplied from the power source to one or more air cleaner components when the electrostatic precipitator cell is at least partially inserted into the air cleaner and when the door is substantially closed.
