The Able Ultrasonic Vaporiser uses a metal diaphragm, silently vibrating at an ultrasonic frequency to create fine water droplets that evaporate into the air as a cool fog. Unlike traditional steam vaporisers, it does not use a heat element, making it a far safer option for the family. This also means there is no condensation on windows or damp walls and furnishings where mould can grow. The Able Ultrasonic Vaporiser is easy to clean, offers up to 8 hours of operation and can be used with any aromatherapy diffuser or pure essential oil. The device also has automatic shut off for peace of mind.
