You should always use 100% natural AromaTech™ blends in your diffuser. Use of other blends or oils may contain fragrances, base oils or synthetics that could potentially result in malfunction or even damage your diffuser.
Some single note essential oils should also not be used in an ultrasonic diffuser. Single note essential oils could have a thick of heavy consistency that can clog up the ultrasonic diffuser, rendering it inoperable.
AromaTech™ blends have all been selected carefully and engineered to be effective for you to use, and safe and above all easy to use in your AromaTech™ diffuser.
