What are substances like enzymes or bacteria called that remove scents?

The term that best describes substances like enzymes or bacteria that actively remove scents is "odor eliminators." These substances work to neutralize or break down odor-causing compounds, effectively removing unpleasant smells rather than merely masking them. This action is often achieved through chemical processes or biological activity, such as the breakdown of organic material by bacteria or enzymes, which can specifically target and eliminate the source of the odor.

In contrast, other terms such as "scents neutralizers" and "deodorizers" can imply different functionalities. While they might suggest a reduction of scents, they do not specifically focus on the biological or chemical action of eliminating odors at the source in the same way that "odor eliminators" does. Additionally, "scent absorbers" typically refer to materials that absorb scents rather than actively neutralizing or breaking them down. Thus, understanding these terms clarifies why "odor eliminators" is the most accurate choice in this context.
