Odor remover is also a type of oxygen absorber, an upgraded version of oxygen absorber. Iron powder reacts with oxygen to achieve oxygen isolation, while the activated carbon in the product can adsorb harmful gases such as formaldehyde and benzene in the air, as well as odors in the air. Through the strong adsorption properties of activated carbon combined with the oxygen absorption effect of iron powder, the effect of oxygen absorption and odor removal is achieved.
