Abstract

An electrostatic filter module for an air cleaner includes a housing having an installation space configured to be sealed at least against ingress of liquid. The installation space has a high-voltage connection and a connection for lower voltage. Arranged in the housing are a separation unit and an ionization unit arranged in the housing, and a high-voltage transformer is accommodated in the installation space of the housing.
