Sorption filter element and sorption filter device

A sorption filter element for a sorption filter device, the sorption filter element comprising:

• a heater;
• a frame enclosing an intermediate space and comprising a separating wall running through the intermediate space, the separating wall being configured to receive the heater;
• and
• sorption filter bodies comprising at least one sorbent, a first one of the sorption filter bodies being disposed on an external side of the frame and adjacent to a first side of the separating wall and being configured to remove carbon dioxide and/or water from input raw air to turn the input raw air into clean air, and the first one of the sorption filter bodies further comprising a sorption filter body grid through which the clean air flows into the intermediate space,
• wherein the heater is configured to heat the clean air within the intermediate space to turn the clean air into regeneration air, and comprises a heater grid through which the regeneration air flows, and
• a second one of the sorption filter bodies is disposed on the external side of the frame and adjacent to a second side of the separating wall that is opposite to the first side of the separating wall, and further comprises a sorption filter body grid through which the regeneration air flows out of the intermediate space into the second one of the sorption filter bodies, the second one of the sorption filter bodies being configured to be heated by the regeneration air and release the CO2 and/or H2O to the regeneration air to turn the regeneration air to loaded regeneration air.
