Just unplug it from the wall.
The product could be used in all room sizes, preferably large to medium size.
To extend the life of the fragrance, occasionally unplug or use at minimum setting for a portion of the day.
One problem is habituation, being constantly exposed to the same fragrance diminishes the perception of the fragrance. (In addition, it could be expected that the fragrance strength would weaken with time).
Unscrew cap from fragrance bottle and insert into warmer until “click” can be heard.
Plug UPRIGHT into outlet.
