These are water-soluble fragrance oils made for one job: putting scent into the air through a machine. Choose a scent and you get a single 10ml bottle of it — the range is sold by the bottle rather than as a fixed assortment, so a shelf of four is four scents you picked rather than eighteen someone else chose.
Twenty-five options cover the ground most rooms need. Fresh and green: mint, lemon grass, lemon, ocean, tea tree, rosemary, eucalyptus. Florals: jasmine, rose, lily, freesia, cherry blossom, osmanthus, lavender. Warmer and sweeter: vanilla, sandalwood, orange, white tea, cologne. Several appear in more than one version, marked with a letter, where the supplier offers a second interpretation of the same scent.
Because they are water-soluble, they disperse in a tank rather than sitting on the surface, which is what makes them straightforward in ultrasonic and cool-mist machines — the kind stocked in our humidifier and diffuser range. Three to five drops per 100ml of water is the usual starting point, adjusted to the size of the room, and the reservoir wants rinsing between scents so one does not carry into the next.
At this price a 10ml bottle is the cheapest honest way to find out whether a scent suits a room, which is not something a description can settle for you. Roughly two hundred drops per bottle works out at forty to sixty diffuser sessions — enough to know whether you want it permanently, before you commit to anything larger.
