Odor absorption refers to the process by which materials capture and hold onto unpleasant smells, preventing them from being released into the air. This phenomenon occurs when certain substances, like activated charcoal or baking soda, interact with odor molecules, effectively trapping them. These materials are often used in air purifiers and odor-neutralizing products to improve indoor air quality. Various factors influence odor absorption, including the type of material, temperature, and humidity levels. For instance, porous materials tend to absorb odors more effectively due to their larger surface area. Understanding these factors can help in selecting the right products for eliminating unwanted smells in homes and other environments.
