Designed by Fabian Zimmerli for Stadler Form. Julia is one of the longest running diffusers available, operating 53 hours between fillings when using the interval mode (repeating cycles of 10 mins on –20 mins off) or 18 hours straight on the continuous setting. She also has a LED light that can be dimmed or turned off completely. Julia automatically shuts off when water empties, giving you peace of mind. Rated Power: 14 Watt
