Revolutionary diffuser: Aera’s patented Microdroplet Technology allows you to control and/or create a scent schedule via Wi-Fi using the Aera App. Customized control: Adjust the setting to your preference of 1-10, depending on the size of the room and how much scent you want to disperse. This device works in small, medium, or large rooms up to 1,000 sq. ft, depending on airflow and position. Long lasting: The no-fade fragrance lasts for an average up to 800 hours when used at level 5. It provides surround-scent technology, which means your space smells great no matter where you are in the room. Safe scent: All Aera scents are made from 100% ethically sourced fragrance and essential oils, making them safe for kids and pets. Unlike aerosol sprays, Aera fragrance diffuses a hypoallergenic effect that is free of alcohol or other harmful VOCs.
