In addition, when a DC voltage is applied by the DC power supply 13, an electric field is generated between the fibers, and the Coulomb force effectively collects dust. Since the electric field is generated between the entangled fibers by the DC voltage, the Coulomb force is always generated and is efficiently collected without being electrically neutralized by the conductive dust.

Alternatively, one or more insulating non-woven fabrics may be alternately laminated. When a DC voltage is applied between the conductive non-woven fabric and the insulating non-woven fabric, an electric field is generated between the conductive non-woven fabric and the insulating non-woven fabric, and the inflow dust is collected by the Coulomb force.
