Already having a humidifier because I am flat in the center of Toulouse with electric heaters, I need to humidify the air in the apartment. I already have a simple humidifier, so I was not surprised by the size of the unit. It is more convenient because allows simultaneously to purify the air and has several levels of ventilation (3 in total)! One can even sleep with the slow speed trouble-free, especially as the unit turns off automatically when the water tank is empty. Its small LCD screen is not the most stylish but still allows a small touch of gaiety.
Use side, I am not sure to use the product continuously for sterilizing (I fear the cost of long-term returns), as the cleaning liquid. But already the fact of placing items in the dishwasher is a plus. See anyway in the long run!
Another small problem, it is quite heavy if you must move the whole time. But I am fully satisfied.
