Essential oil diffusers and humidifiers are not the same. While an Essential Oil Diffuser can put moisture in the air, most will only add a small amount of humidity to the room. There are few essential oil diffusers that add enough moisture to the air to be thought of as a humidifier. Young Living diffusers that are also atomizers and humidifiers are the Desert Mist and Dewdrop diffusers.
You may use any mild, non-toxic cleaner of your choice to clean the diffuser. Any cleaner that is considered corrosive (such as bleach, strongly acidic cleaners, etc.) should be avoided. Please note, if the diffuser has a metal ultrasonic plate, use rubbing alcohol to clean the plate as instructed in the product manual.
Essential oil diffusers are excellent tools to get beneficial essential oils into the air, where their effects can be felt. They have long been used in aromatherapy treatments as they help to cleanse the air and promote soothing feelings in the environment.
