An odor neutralizer is a product designed to eliminate unpleasant smells rather than just masking them. These products work by chemically interacting with odor molecules, rendering them odorless. Commonly used in homes, cars, and public spaces, they can come in various forms, including sprays, gels, and plug-ins. Many odor neutralizers contain ingredients like activated charcoal or baking soda, which are known for their ability to absorb odors. Some may also use essential oils for a pleasant scent. Popular brands include Febreze and OdoBan, which are widely available in stores and online.
