Chroma Home is an ultrasonic aroma diffuser that works by mixing oils with water, then using ultrasound to turn the mixture into a cool vapor that is carried into the room. This is very similar to how an ordinary humidifier works, meaning it will also gently humidify and moisturize the surrounding air. Blown by hand, one at a time: every shade is hand-blown, so the three stacked curves and the thickness of the glass vary slightly from piece to piece. Light gathers where the glass is heavier and softens where it thins, so no two Chroma Homes fill a room in quite the same way.
