Pompelmo Cassis is wonderfully relaxing: it purifies the air and lifts the spirits.
The best way to choose the right size of the bottle is to start with the extension of the space you want to scent:
250ml > 8-10 sqm*
500ml > 20-25 sqm*
The use of the sizes 1250 ml, 2500 ml and 5000 ml, surely suitable for ambiances usually larger than 15 sqm*, besides granting an effective perfume, represent a real home decor element.
*the sqm are indicative and usually refer to ambiances with high ceilings, average 2 meters height
The 100 ml diffuser is useful to scent only small areas (ex. walk-in closets), the spray instead to refresh them temporarily.
In the center of a room or, for larger ambiances, it is recommended to have 2 in opposite sides of the area.
