How Does a Refrigerator Deodorizer Work?

Odors and pH Levels

The science behind odors, including those found in your refrigerator, revolves around chemistry and pH levels. The pH level determines the acidity level of a product. In food, the higher the acidity, the greater the chance that a foul odor will be produced as the product ages and breaks down.

Sodium Bicarbonate

The best way to kill the odor developed by the breaking down of a product is to neutralize the acid produced. This is where sodium bicarbonate (otherwise known as baking soda) comes to play. Sodium bicarbonate has a well-known ability to neutralize the acidity levels and act as a buffer to bring pH levels back down to a neutral level. Instead of just blocking odors, sodium bicarbonate neutralizes the odor completely.

Where to Place Your Deodorizer

Most odors weigh approximately the same as the air around them. This means that the only way to maximize the odor-ending potential of the deodorizer is to place it as close to the odor causing product as possible. It is also important to be sure that the deodorizer is not blocked by other products in your fridge.
