Our natural air fresheners are made with 100% authentic essential oils and that's all! We curate each essential oil for it's terroire (country of origin and soil), and quality of aroma. We offer two types of air fresheners, Hanging Air Fresheners and Crushables, small units that activate when you crush them. It's instant aromatherapy in just one crush! They last for 1 day to one month depending on the space you put them in. Large or windy spaces will consume or evaporate the essential oil more quickly than a drawer's air tight capacity. Many people choose to activate and inhale them just for instant aromatherapy and change in their mental disposition.
