A disposable CO2 absorber for applications in rebreathing systems uses a flexible bag-like pouch to contain CO2 absorbent granules. The pouch includes an intake port having a one-way valve at the top of the pouch and an outlet or exhaust port including a perforated cylindrical tube or perforated disk in the bottom of the pouch. Exhaled gas containing CO2 passes through the one-way valve at the intake port and contacts the absorbent granules where a chemical reaction bonds the CO2 with the granules. The residual gas, substantially free of CO2, passes out of the pouch through the exhaust ports for rebreathing by the user. The flexure of the pouch increases the efficiency with which the CO2 is absorbed.
