Abstract: An air freshener is composed of a diffuser with a wick system that is impregnated with a liquid fragrance contained in a replaceable bottle or receptacle whose liquid perfume, which is made and included in concentrate form, is obtained from natural essences to provide a long life. The air fresher is provided with an adjustment for the volume of the air freshener by volatilization of the fragrant product by a simple turn of the head cap, at the user's discretion. It is possible to stop the product from issuing when the vehicle is not in use, thus saving its consumption.
