Abstract
A filter element for filtering a fluid passing through the filter element, the filter element having a fluid entry face and a fluid exit face and is provided with a group of first channels and a group of second channels, through which the fluid to be filtered can flow from the respective first channel into the second channel, that is arranged next to it, wherein a through-channel leads through a filter pack from the fluid entry face to the fluid exit face, which through-channel has an opening at the fluid entry face and/or has an opening at the fluid exit face, wherein an element closes the flow of fluid through through-channel, while leaving a volume open inside the through-channel that is at least 10% of the volume that the through-channel would have without the element, or the element allows the flow of fluid through the through-channel and interacts with the flow of fluid through the through-channel and/or the sidewalls of the through-channel deviate at least in some areas from a cylindrical wall in order to thereby create an element that interacts with a flow of fluid through the through-channel.
