Room air fresheners are products designed to improve the smell of indoor spaces by masking or neutralizing unpleasant odors. They come in various forms, including sprays, gels, plug-ins, and automatic dispensers. The main function of air fresheners is to make a room smell fresh and pleasant by releasing a pleasant fragrance into the air. Common scents include floral, citrus, lavender, or fresh linen. Some air fresheners also contain antibacterial or deodorizing agents that help eliminate bad odors rather than just masking them. These products are often used in homes, offices, and public places like bathrooms to maintain a clean and inviting atmosphere. Room air fresheners are easy to use and offer instant results. However, it's important to choose one that is safe for both humans and pets, especially if it is used frequently or in enclosed spaces.
