The cover is made of glass, and the internal reservoir is constructed from Food-Contact Grade BPA-free PP material, which is crack-resistant and can resist essential oil corrosion —— it’s also friendly to your babies and pets. How long can it work when fully filled with water? This diffuser has a maximum capacity of 120ml, working up to 6 hours in continuous mode and 12 hours in intermittent mode. Auto shut-off when waterless – use it with confidence all night. Why does the product stop working or produce less mist after being used for a period of time? No need to worry. This is normal for ultrasonic aroma diffusers. Mostly, the nebulizer disc in the tank is clogged by essential oil residue from infrequent cleaning. We recommend cleaning the tank regularly and drying it with a soft paper towel. What are the innovations of Onaboviva? Beyond core functions such as cool mist technology, automatic shut-off without water, and timer, we’ve added innovative features — continuous/auto mist and sleep mode — to enhance your daily routine. Why choose Onaboviva Essential Oil Diffuser? Onabotiva features handcrafted glass design, ensuring a premium look and feel that surpasses other products. Combined with patented original aesthetics, it prevents the influx of low-quality imitations.
