The H2EO AirCare Ultrasonic Diffuser utilizes quiet, "cold mist" technology to help you benefit from the aromatic and therapeutic effects of essential oils. There is no heat or air pumps, which can damage the chemistry of essential oils.
High frequency sound, that is 100 times beyond what the human ear can hear,generates patterns of movement that create "sonic bubbles" in the water in the diffuser's bowl. When these bubbles implode, nano-droplets of water are released from the surface. Each is enveloped by a fine coating of the essential oil, floating up and rapidly becoming part of your room's atmosphere.
