Now you can enjoy the therapeutic benefits of aromatherapy while also enjoying the pleasing & soothing sound effects of a water fountain! This ceramic diffuser is available in two colors: cobalt blue or natural. It effectively scents up to 500 sq. ft. and is extremely simple to set-up and operate. If you are looking to simply scent a room – look no further ~ this unit works better scenting rooms than most of the fan-driven diffusers we have tried. The AQUAROMA fountain diffuser pump, imported from Germany, is created specifically for using essential oils. Most fountain pumps would shut down or clog up if essential oils were put into the system.
