Then I bought last year these humidifiers and am still very happy. All the problems I had with the water heater, are not present here:
Benefits:
The unit is also in the highest humidifier very quiet (about the volume of an average laptop fan at medium speed).
Humidifier continuously variable
low energy consumption
The humidifier takes over the useful life not from by calcifying equipment parts.
Easy cleaning (cleaning brush included)
Separately removable water tank with handle
Pivoting steam outlet
Disadvantages:
As with any ultrasonic one should be careful not to direct the cold steam on furniture or parquet, can be thrown moist.
I could dry the equipment and combat watery eyes, headaches and sore throats in winter successfully and the humidity in the heating period of about 32 - 35% increase to 50-55%.
