It is not advised to use alternative essential oil within the AMI system. All essential oils from the AMI essence website have been tried and tested with the components within Insignia steam generators. The event of a failure in the generator due to a non-tested essential oil will result in a void warranty on the generator.
We do not advise to use an alternative essential oil with the AMI system. All of our essential oils are created for our systems only. Steam mixed with essence carries different properties – it can and does break down chemical contents of the original constituents.
Our essences are trailed and tested with our systems to eliminate the highly dangerous reactions that can occur when using a different oil. To be able to sell essences for our purpose you need a cosmetic license set by the E.U. 99% of essences on the market are not totally pure, this means that they are using synthetic and do not have a license.
