deodorizer

This term refers specifically to the agent or tool used to neutralize odors, distinguishing it from a deodorant. While a deodorant is typically applied to the body to prevent the onset of sweat-related smells, a deodorizer is generally used on surfaces, in rooms, or within containers to remove smells that are already present.

In commercial and industrial contexts, the word often describes chemical agents or mechanical filtration systems. In domestic settings, it typically refers to consumer products like scented gels, charcoal bags, or spray canisters.
