Abstract
A regenerable carbon dioxide scrubber includes at least a first housing compartment including an inlet, an outlet, and an interior region. A sorbent material is located within the interior region of the first housing compartment, in which the sorbent material (a) attracts and/or retains carbon dioxide from an air supply passing through the sorbent material at an operating temperature below about 100° C. and (b) releases carbon dioxide at a regenerating temperature above about 150° C. A rebreather including the regenerable carbon dioxide scrubber may be used to scrub carbon dioxide from a user's exhaled air.
