Zen can be defined as a condition of meditation and calm, in which one finds insights on how to behave. These Zen diffusers will certainly work to aid in any form of meditation or mindfulness that you seek. Aromatherapy has been used for centuries to promote wellness and harmony of body and mind. Ceramic diffusers need only tap water and fragrance or essential oils to fill a room with beneficial aromas. Using ultrasonic vibrations, these diffusers create minuscule particles that disperse as a mist into a room. By using this ultrasonic technology instead of heat, which can break down the oils, the maximum benefits of the oil are protected and can be enjoyed.
