the bottom shelf of the refrigerator

Due to temperature differences, convection occurs inside a refrigerator, causing odor molecules to tend to accumulate in the lower part. Therefore, placing a deodorizer on the bottom shelf makes it more effective at absorbing odors throughout the entire compartment. The bottom of the refrigerator also tends to stay slightly cooler, which is an ideal environment for deodorizing agents to work efficiently. Simply adopting this habit can greatly improve your refrigerator’s odor control.
