Fridge odors stem from poor air circulation. When air cannot flow freely, certain areas become warmer and more humid. This creates breeding grounds for odor-causing bacteria. Research shows that simply leaving space around items, especially near b...
You open the fridge to smell something mild and cold, but instead, you can smell something strange, which persists even after you clean it. It is not necessarily the food in your fridge that creates this unpleasant smell, but the flow of air within the fridge that is the root cause. According to research published in ScienceDirect, it is important to have good air circulation within your fridge for it to be able to maintain a consistent temperature and humidity. Where air cannot freely circulate, some parts will have a higher temperature and humidity level, which makes them the perfect environment for odor-causing bacteria.
Blocked airflow starts creating odor zones?
It is important to note that the back portion of a fridge is vital when it comes to the circulation of cooled air. Various research works done on refrigeration systems state that both natural and mechanical airflows require proper channels for their distribution. If items are arranged near the vents or are placed in a dense manner, then there will be certain hindrances in the free flow of air. According to an Applied Thermal Engineering journal article, such minor hindrances can create "dead zones" in which airflow becomes stagnant, leading to moisture accumulation and temperature variations. These factors contribute to faster microbial development and odors.

The Small Change That Makes a Difference
The problem of improving air flow is not particularly complicated. According to the research on air and moisture management, keeping some space around things may considerably affect the flow of air in the refrigerator. The provision of a gap next to the back vents will allow air to move freely, thus preventing humidity accumulation and regulating temperature. With the proper arrangement of things, equilibrium can be restored easily. By making sure that air can freely circulate, you avoid accumulating odors from the very beginning.
