ABSTRACT:
A respirator with blower support for the flow through at least two filters in the breathing gas lead is provided such that the flow of one of the filters temporarily is in the inhalation direction and the other flow is in the exhalation direction respectively and their flow through direction is periodically reversible. This allows flow through of the filter in small volumes without a premature bursting or filter depletion. The wearer comfort should remain and the blower support is not diminished in its operation.
