## Overview

The Boneco U350 Ultrasonic Humidifier combines advanced high-frequency technology with a large 5L top-fill tank to deliver pure, micro-fine mist in either warm or cool modes. Featuring a digital LED touch panel, programmable hygrostat, and integrated AQUA PRO water filter with antibacterial Ionic Silver Stick, it ensures clean, residue-free humidification for spaces up to 80m². Its dual jet nozzles and essential oil container let you customize airflow and fragrance, making it a sleek, quiet, and efficient solution for year-round indoor air comfort.

## Description

"""The BONECO U350 is an ultrasonic humidifier that can release cool or warm mist. It features an easy-to-read digital display with helpful reminders such as when to refill water or clean the device. You can easily adapt the U350 to meet your needs with AUTO mode, timer function and fragrance container for essential oils. The humidifier converts the water into a microfine mist which is dispersed into the air and can be distributed in two directions using the double jet nozzle. An integrated demineralisation cartridge ensures that the water mist is limescale-free, and the Ionic Silver Stick provides optimal water quality with antibacterial effects. The programmable hygrostat allows you to set your ideal humidification levels, while the digital display shows all functions at a glance. The U350 features a large water tank for long running time and provides a high humidity output covering areas up to 80m. """

Review: Disappointing :( - I bought four humidifiers from Boneco so far, and this one failed after only 11 months after the purchase. The water refill/recycle symbol just stays on...I tried all the solutions on the desertcart.com https://www.desertcart.com/ask/questions/TxJFP44U37Y7O1/ref=ask_ql_ql_al_hza and it remains unsolved.
Review: Very quiet, 5 L capacity which lasts much more than one night. Disperses humidity seemingly quickly and effectively - stops dry coughing at night when normally humidity levels drop. Not sure if the LCD % numbers are correct but device does change humidity in rooms of 50-80m sizes. Easy to use via touch buttons plus appears to have some heating function for warm mist. . No visible mist coming out (this can discolor nearby furniture (whitens) over time) from the 2 swivelable outlets, unlike another popular “M” brand I used which is bulkier and noisier. Has a so called antibacterial “Sonic” baton inside which is quite expensive to replace but hopefully lasts many months. Has also a filter piece inside (for kalk?) which can also be replaced… Overall bought as highly recommended by UK reviews and meets expectations…

J'ai eu plusieurs humidificateurs pour ma maison trop sèche. Celui-ci tient vraiment ses promesses en plus d'être ultra silencieux. Seul bémol le prix des sticks a remplacer régulièrement.
