A carbon dioxide absorber () and a closed-circuit breathing apparatus () with the carbon dioxide absorber are based on the carbon dioxide absorber having an inlet () and an outlet () gas-tight connectable by a flow duct (), in which a material () is arranged, which absorbs some carbon dioxide contained in the breathing gas stream sent through the material. The flow duct () is enclosed in some areas by a housing (), in which a window element () is arranged. A display element () arranged movably in the flow duct () is visible through the window element from outside of the housing and/or through which window element the radiation reflected by the display element () exits to the outside. A distance between the window element () and the display element () varies as a function of the quantity of carbon dioxide-absorbing material arranged in the flow duct ().
