A diffuser is a great way to scent your space safely and naturally. Place a diffuser in your bedroom, living room or office and develop positive feelings, disinfect the air, or just create a calming feeling by diffusing different aromas throughout the day. Ultrasonic essential oil diffuser is an amazing aromatherapy device to create the atmosphere you desire.  It features an easy to use 500ml water tank,  different LED light colors, multiple mist nebulizer modes, as well as a safety auto-switch that prevents it from overheating in case it runs out of water.
