That's what makes this device very well.
It consists of two separable parts.
- Above essentially the four-liter tank with a removable swivel spout wish.
The tank is filled by unscrewing the filter at its base, behind the blue glass part.
- Below that, essentially, the part with all the electronic device and settings buttons. These buttons are all an obvious purpose: on-off, steam emission power (cold: it is actually a mist emitted by an ultrasonic generator), desired humidity, timer (optional , 1 hr. 24 hr.), emission of negative ions desired or not (it can slightly help asthmatics acting somewhat on the concentration of dust and pollen grains).
Once the desired humidity recorded (ranging from 40% to 95%), the unit turns on (see my photos below) when it is 3% too low. I chose 50%. Power consumption is very low: maximum 30 watts transmitting. The machine stops automatically when the water level becomes insufficient. The fan (virtually inaudible) stops working soon after.
Two very minor points I think are improvable.
- First the French part of the manual is full of (large) fouls. Fortunately, the device pattern himself is very clear and its use is, as I just explained, almost obvious. So it's no real importance, but still a shame in making contact with as good a unit.
- Then, the three concentric circles symbolizing the light steam emission strength are only active when this vapor is emitted. The setting is a little faster if they were at all times.
Finally, my attention was drawn to a remark of another commentator, with which I was initially agreed: the apparent impossibility to distribute products to the pleasant smell with the steam. Indeed, almost all less dense than water, they stagnate in the reservoir surface. But, on reflection, I thought that the receiving water basin in the lower part could be suitable. I tested the idea with a few drops of eucalyptus oil highly concentrated. And it works very well. So a non-intended use (or in any case not announced) by the manufacturer surcharge.
