The diffuser unit and each fragrance flask are listed as separate options on this page, so you can start with the unit and add whichever scent you like, then swap it any time. How long can I leave the Plug-In Diffuser on?Ecoya recommends a maximum of 6 hours at a time. This helps prevent overheating and supports the best fragrance throw. Do I need to do anything the first time I use it?Yes. For best results, run it for 1 hour initially to allow the wick to fully absorb the fragrance. Can I plug it into an extension cord or multi-board?No. Plug it directly into an upright wall socket only. What about pets?Ecoya fragrances are formulated in line with IFRA standards and are phthalate-free. Ecoya advises keeping the unit out of reach of children and pets and using it in a well-ventilated space. For a flame-free alternative for larger rooms, try our Ecoya reed diffusers.
