The reason for the purchase of this device, the permanent cold of our little treasure was. The humidity in our bedroom is still too low, even the little ones and his runny nose is not my opinion benefited. Thus I enschloss me so quickly to obtain a device without but now to buy a super professional and expensive equipment. I read some reviews here on Amazon and decided for this device. Have it now already some time in use and can say the following: - Start-up: super easy - Maintenance: also not worth mentioning, and as we go through our Hausentkalkungsanlage anyway have very little or no lime water and use for this device, the calcification keeps in line. - Volume: Yes, that's probably difficult to evaluate and because probably everyone has his own "bar". Listen to the unit in the bedroom doing quite well. But feel it is not particularly disturbing, because it is not nervendes perfumed. We have it but anyway overnight rather not run, but some time before we go to sleep. It has also been written by a bubbling here, which I do not find absolutely disturbing. This is always when a certain amount of water is from the nachgeströmt Voratsbehälter and has thus made a vacuum in the container. Sometime tearing this vacuum draws air from then and which is accompanied by a short bubbling. Not more. - Effect: Must say that I am a bit since überracht. Our bedroom has about 20 square meters and because the device works quite quickly. From 30% to 60% and more in less than an hour, I find great.
Conclusion: I'm super happy with the device. Works well, is cheap and would buy it again. If should turn out in the winter months but that the instrument but should be in operation longer and therefore would also run overnight times by a certain humidity value not to fall below, so I would then but a humidistat want on the device. This could then automatically turn off the power when it reaches a desired value and switch on again when it falls below. This would have the advantage that the device would have a lower duration and would thus make less perfumed. And in a smaller room would thus avoid that the device, when it passes through overnight, the humidity level increases too much and one morning in a stalactite cave wakes :-), joking .... I could also easily be reached by an external device connected to the cable, humidistat. Since this unit right switch (with locking function and no electronic switch) has, also keep their operating position when the power is disconnected from the unit time, it also works with a previously connected external humidistat that. For those who can not start over with my statement here now ....... that looks like this as a front-connected switch, how to control the Christmas lights. But not with a switch but a humidistat.
