The aroma diffuser uses a unique ultrasonic vibration method. After adding essential oils, the aroma diffuser automatically sprays atomized ultra-fine water molecules, adjusts indoor humidity, releases negative ions, precipitates dust, removes harmful substances such as formaldehyde, diffuse fragrance, and makes indoor air exceptional Fresh. You can use it when guests are visiting, indoors with peculiar smells, requiring carefulness, refreshing, or even yoga and fitness. With different scented essential oils, the mist generated by ultrasonic waves will diffuse the scents and achieve various effects you want. ●Features: The brightness and spray can be adjusted separately, which can be used as a lamp alone, and can be turned off when used as a spray during the day. The spray can be set to 4 groups of time, the shortest 30 minutes, the longest 3 hours. With two brightness adjustment buttons, it can be used as bedside lamp and night lamp. Automatic power off without water, safe and secure. ●Size: 75mm in diameter and 130mm in height. Water tank: 65ml, humidification capacity 30ml/hour, noise <36db, light color: white warm light ●Reminder: The applicable area is 20 square meters for aromatherapy and 10 square meters for humidification. Press the mist button for one second or longer to turn on the spray function. The spray effect will get bigger and bigger after 15 minutes of operation. The suitable amount of water is about 45ml, but the spray is too small. ●Essential oil types: For those who want to relax and help sleep or use them in private spaces such as bedrooms, you can choose lavender, sleep comfort, rose and vanilla.

Tea tree: Purify the air, sterilize and deodorize, refreshing. Tips: 1: Ultrasonic atomizer uses electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz), through the high-frequency resonance of the ceramic atomizer, the liquid water molecular structure is dispersed to produce a natural and elegant water mist. Compared with ordinary heating and atomization method, energy saving is 90%. A large amount of negative ions are released during the atomization process, which precipitates smoke and dust floating in the air. It can also effectively remove harmful substances such as formaldehyde, carbon monoxide and bacteria, purify the air and reduce the occurrence of diseases. 2: Ordinary humidifiers cannot use essential oils, because essential oils easily react with the plastic of the body and produce toxic substances. The PP safe and environmentally friendly materials used in this humidifier can effectively prevent the inner wall from reacting with essential oils. The ultrasonic humidifier uses 2 million times of ultrasonic high-frequency vibration per second to atomize the water into ultrafine particles of 1 to 5 microns, negative oxygen ions, and negative oxygen ions to achieve uniform humidification, refresh the air, and improve health. Change the heat of heating in winter to create a comfortable living environment.
