Air fresheners are made using a combination of fragrance oils, solvents, and propellants. The fragrance oils are the key ingredient, providing the desired scent. Solvents are used to dissolve the fragrance oils and help disperse the scent into the air. Propellants are added to the mixture to help release the fragrance from the container. The ingredients are mixed together and then filled into the chosen container, such as a spray bottle or a gel dispenser, to create the final air freshener product. **
