So first I hung a wide planter with an aluminum frame on my radiator and filled it with water, in the planter was a towel that hung at the same time on the top of the radiator, fully drawn and the water evaporated then. That brought in my living room 20 square meters about 38% RH, at times even more than 40%. But for this then also had the heating be fully at what energy actually costs only during the day is impractical.
Looking at the commercial units, the evaporation device came out of the question, because they eat too much power for me.
In the evaporators / nebulizers have to watch in turn, that they distribute any germs in the room, because the water is not heated and no germ killing takes place.
In the above device first of all think of phenomenally low power consumption (below 10W), since only a fan driven the anpustet a roller which is rotated in a water bath. This has due to the many plastic discs on a surface 4qm, it is wetted at each revolution of water, which is then "cold" evaporated.
The germination problems encountered by the company a water additive, which 14d may be left in the water. Another effect of water addition is a lowering of the surface tension reduction from water so that wetting of the roller slats works better.
So far so good. To test the device I have it ordered and me times one week run at medium speed in continuous operation.
Conclusion: Of the 10l fuel tank capacity of the unit has approximately 6l evaporates daily (be within 1min to simply filled again) what the humidity has increased to about 45% with an open living room door, thus creating a pleasant climate in the apartment of 90 square meters. With the door closed, the humidity went on even to about 55%, this could have been a device of this size can also chokes.
From the smell of her, the air smells neutral, at well above 50% RH, the air acts subfektiv bit musty.
As for the air filter function is after 1 week a slight layer of dust on the floor of the unit. Whether the germ killing is work itself difficult to judge for someone who dares to relevant tests (Ökotest) it seems to work quite well indeed.
Bottom line, the humidification top notch and the electricity consumption is very low. As for the sound, there is a low frequency hum that can be heard even on the smallest stage and the addition would sleep for me too noisy, but during the day is not a problem, even on a medium setting. In stage III, the part sounds like a fan and then a bit annoying.
In terms of processing affects the device externally solid, but the price of the delivered simple technique is absolutely horrendous, here you pay apparently the patent.
To me it was worth it, even if I would have had no problem with a towel over the heater.
