Aera uses the airflow in a room to evenly circulate super tiny scent molecules. How large an area will vary depending on ceiling height, whether there are partitions or other impediments to air circulation, and the natural airflow in a room. But in general, placed correctly, one Aera will scent a room with an open floor plan and average ceiling height of 12 feet between 50-1000 sq. ft.
Aera is fully adjustable for small, medium, and large rooms. For small rooms, we recommend placing your diffuser on scent setting 1-3; for medium rooms 3-5; and for large rooms 5-10.
