Scratch & sniff. Alternates for lasting freshness. Morning walk. The sun seen through trees. Wind billowing the tall grass. A morning walk refreshes. Like the scent of the dew on grass. In the morning air. Eliminates odors in the air caused by bacteria and freshens. Freshness you notice for more than 30 days (on low). Automatically alternates throughout the day so you don't get used to the same scent. Cleansing rain. Droplets on branches, and rain glistening on green leaves. Cleansing rain renews like the scent that follows a rainfall.
