Deodorizers are products designed to mask or eliminate unpleasant odors in various environments. They work by neutralizing odor-causing substances or by releasing pleasant fragrances. Common types include sprays, gels, and plug-in devices, which can be used in homes, cars, and public spaces. These products often contain ingredients like fragrance oils, essential oils, or chemical compounds that target specific odors. Some deodorizers are formulated for particular areas, such as bathroom deodorizers or pet odor eliminators, while others are more general-purpose. Regular use can help maintain a fresh and inviting atmosphere in any setting.
