"FABULOUS DIFFUSER for small to mid-sized rooms"
This is a lovely, reasonably quiet, humidifier for small to mid-sized rooms. It looks attractive & is quite relaxing to watch. It has a timer which allows you to leave it on for up to 6 hours, without the water drying up. My preferred essential oils are currently lemon & lavender and I use a few drops of each to give a lovely light, outdoor freshness to the room. The room I use it in measures approx 20ft x 11ft, for rooms that are much larger than this, I would recommend you look at the reviews for larger capacity or more powerful diffusers.
