Absorbs $CO_2$ and increases $O_2$ content

(A) $KO_2$ (potassium superoxide) is used in oxygen cylinders because it reacts with $CO_2$ to produce $O_2$ and potassium carbonate $(K_2CO_3)$.The chemical reaction is: $4KO_2 + 2CO_2 \rightarrow 2K_2CO_3 + 3O_2$.This process simultaneously removes $CO_2$ and replenishes $O_2$ levels.
