Yes, Aera is the only home scenting device which offers you 10 adjustment settings. The + and – buttons located on the top of the Aera device allow you to control the amount of fragrance with settings 1 to 10. The AeraForHome app for Aera Smart allows you to make fragrance intensity adjustments anytime, from anywhere.
NOTE: Increasing the scent level will not necessarily lead to a stronger, more noticeable fragrance effect in your space. Increasing the scent level primarily acts to expand the range of this fragrance effect.
