You can use your own pine and eucalyptus oils in our NebulO3 as long as it matches the mix we provide with the unit. If you can't find your own, you can easily purchase our premixed half ounce bottle when you run out.
A proper mix of pine and eucalyptus is essential for proper operation of the NebulO3.
To make your own, use two parts pine and one part eucalyptus.
