operating principle: Under the principle of electronic vibration, high-frequency oscillating wave (ultrasound) generated by the ultrasound atomizer will break up the structure of liquid molecular through ceramic piezoelectric oscillator and break essential oil into tiny vaporific particles. Along with that, a larger amount of negative ions are released from water and combined with smoke and dust floating in the air. Through precipitation and filtration in electrostatic treatment, formaldehyde, carbon monoxide, bacteria and other harmful substances and odor can be effectively eliminated from this combination. Concrete sealer: 1. High-intensified, uniform and high efficiency humidification; Energy saving; Super-long service time; Automatic humidity balance adjustment. 2. When used with watter, the high concentration of negative ions which produce by it, can purify air and reduce diseases through effective elimination of harmful bacterial and viruses floating in the air. Increase indoor humidity. 3. No noise, adjustable air humidity in car, the tiny vaporific particles of essential oil can exorcise cigarette smell and other badly smell. 4. It is extremely dry indoors and in car in winter. Dry air causes people easy to catch a cold in sour throat, asthma, and other symptoms, which speeds up the life of aging. On the contrary, fragrant and humid air can maintain the vitality of people. 5. High security with no risk of fire Free from heating, essential oil molecules will not be destroyed (essential oil is oxidized under heating), therefore it is entirely green with no pollution to the nature. Efficacy: * The product can provide flesh air (Oxygen hormone), improve air quality, activate brain cells, and supplement energy to brain. * Sufficient vital air purified by negative ions and the tiny vaporific particles of essential oil can improve heart and lung function, reduce respiratory burden, and remove damages from second-hand smoke, dust hiding and allergens. * The tiny vaporific particles of essential oil is with the function of skin moisturization and beautification, and horny layer softening in pursuit of moistening and polishing skin, as well as skin metabolism and detoxification promotion, the product can be the best moisturizing product of all kinds be used. The 100% atomized nature essential oil particulates absorbed by the body in nasal chambers or lungs plays an important role in regulating the functions of endocrine and immune system with natural pharmacological efforts. It can be used for both treatment and entertainment purpose. * Being able to ease nervous, release pressures, calm down minds and comfort feelings, essential oils can be used for different types of mental health treatment such as insomnia treatment in improved sleep quality.
