What type of oils can I put in my nebulizing diffuser?

Use only AromaTech diffuser blends; other blends and oils may contain base oils that could result in malfunction. Many single note essential oils should not be used in the diffuser. Single note essential oils may have a thick or heavy consistency that can clog the diffuser and cause it to stop diffusing scent. AromaTech diffuser blends have been carefully blended to be effective for you, and safe and easy to use in your cold-air diffuser.
