Cartridge for capturing co2

Abstract

A cartridge for capturing or absorbing CO2 from a user's breath includes a storage space for an adsorbent product (P) to adsorb CO2. The product is in the form of grains, in particular soda lime. The storage space includes a bottom and an opening opposite the bottom, and a compression member arranged on the side of the opening in the storage space. The compression member is movable in the storage space towards the bottom and may tamp down the adsorbent product in the form of grains against the bottom of the storage space. The storage space includes a spring that may exert a force on the compression member tending to push the compression member towards the bottom of the storage space.
