An operating and changing apparatus for a filter body located at a filter position that displays a filter body axis of symmetry located at a filter position and in which a particle filter is integrated in order to remove particles from a particle-laden fluid. The filter body has a fluid-permeable filter body opening and a fluid-impermeable filter body wall section. The apparatus has a housing that the fluid can flow through with a flow channel in which the filter body is so positioned that the fluid can flow through the particle filter. The flow channel has a flow inlet and a flow outlet such that the fluid flow between flow inlet and outlet runs through the particle filter of the filter body. The flow channel has a channel axis which runs parallel/collinear with the filter body's axis. The flow inlet and outlet are offset to each other, relative to the channel symmetric axis. The flow channel and the housing have a filter insertion opening and a filter disposal opening that are in alignment along the channel axis. A change of the particle filter takes place through exchange of the filter body with an exchange filter body with a replacement filter whereby the replacement filter body can be pushed through the filter insertion opening into the flow channel and the filter body to be replaced can be pushed out of the filter disposal opening by the pushing-in of the replacement filter body. During the pushing of the filter body, the flow inlet and outlet are blocked fluidically by the impermeable filter body wall segment until the replacement filter body has reached the original filter position such that the flow channel is not open during the change and the change is accomplished almost entirely without interrupting the flow.
