As a powerful ultrasonic nebulizer, Oliver rapidly increases humidity. Hygiene is ensured by a UV lamp, which illuminates the water before nebulization, thereby eliminating 99.99% of all germs. The water tank can be conveniently refilled during operation: open the lid at the top, pour in water, and you're done. A few drops of essential oil in the integrated fragrance dispenser – and the humidifier also diffuses a subtle scent. The desired humidity can be flexibly adjusted between 30 and 75% using the hygrostat. In Auto mode, the humidification level is automatically regulated – for quickly achieved and consistent humidity.
