The ultrasonic diffuser doesn't generate any heat, making them safer than conventional diffusers which boil water to produce water vapor.

Once the smart sensor detects no water in the diffuser, it'll automatically switch off. You can put any essential oil of your choice. If you wish to put your favourite fragnance you can also do so. We recommend putting 1-2 drops/puffs at first to see how strong the scent will come out. Then, you can top up to your personal liking. No, it’s not real flame, it is just designed to look like it. It is just fog that is created through modern technology and that is not warm. It is completely harmless and extremely eye catching to the human eye. It is better to use distilled water, but of course you can also use tap water, but after use, clean the inside where the water was located to avoid the formation of bacteria.
