— filter in the form of an adapter plugged directly into a power outlet. The absence of a cable, on the one hand, makes such devices as compact and easy to transport as possible, on the other hand, it does not allow the use of large cases with an abundance of their own sockets and extensive equipment. Therefore, most filters of this type are very simple devices for one outlet.
