Dirty electricity is a broad term that describes the measure of electrical noise present on the wiring of a home or building. This electrical disturbance is often also called microsurge electropollution, electromagnetic interference (EMI), line noise, transient frequencies, harmonics etc. Dirty electricity is mainly caused by electronic plug in devices and other appliances that add additional frequencies onto the wiring circuits through their non linear action. Each household generally adds to the DE, and this is passed onto neighbouring houses through the electric supply loop. Removing DE is done by adding capacitative filters into the electric sockets.
