An air freshener is a scented product designed to improve the odor and overall ambiance of indoor spaces. It typically comes in various forms, such as sprays, gels, solids, or plug-in devices. Air fresheners release pleasant fragrances into the air to mask or neutralize unwanted odors, creating a more inviting and pleasant atmosphere. They are commonly used in homes, offices, cars, and other enclosed spaces to provide a more pleasant olfactory experience.
