Device well designed, good quality and easy to use. Composed of 2 removable blocks, the reservoir when filled from below and screwed back the cartridge, simply stand it on its base and put on with the on / off button. The control panel provides other important functions: - Can modulate the humidity of 40 to 95% as required, the vapor flow rate is adjustable and can guide the outlet nozzle in the most useful direction. - The camera automatically starts for 1 hour fog but it is also possible to configure it for the duration of his choice to the maximum of 15 hours or he will have exhausted its reserve of 4 liters of water. The camera turns off automatically when it detects a lack of water. Once off, the fan continues to run a while and then stops also. - If the appliance is operated without time limitation, integrated hygrometer is responsible for monitoring the humidity in the room and shut down once the desired percentage is reached. - A button to use the "negative ions" function, which apparently allows to offer a very sanitized air humidification but I do not know more about it and to have no difference with this function activated. People who suffer from certain specific pathologies are perhaps more sensitive. - A night mode turns off the control panel, useful for the night, but the tank is lit up. The light does not bother me, as opposed to engine noise. I recognize that this device is very noisy but the complete silence when you need to sleep, it can become annoying. In this case, it is best to prepare the room before and schedule it for a short duration at the time of sleeping. This humidifier is well thought out and well done. Very popular to relieve dry cough, aggravated by including heating.
