For a perfect sensory interior decoration: when you use the diffuser for the first time, insert the sticks letting them soak for about one hour before turning them upside down. The fragrance will start to spread its scent in the room. We recommend to turn the sticks periodically or whenever you want to revive the intensity of the fragrance. We also recommend to always keep the liquid level above half the capacity of the diffuser; this way you will prevent the quantity of oxigen in the diffuser from negatively affecting the evaporation rate. The duration of a fragrance changes according to the features of the room where the diffuser is. If the interior is wide, we recommend to put two diffusers in the opposite corners of the room.
