School grade 6

All the text are basically again only my opinion and memory. So can some of it be wrong, because it is wrong in my memory. This I beg to be considered. If I wrote something wrong, then it was not aware and I order message in the comments box, so I can rework immediately here.

It should first be mentioned that Venta uses a disinfectant. Öko-Test had mE said it was benzalkonium chloride and it gets into the air. Venta has towards me once told that it was actually benzalkonium chloride. In a second request at a later date this question has not been clearly answered. It must also be borne in mind that water with detergent / disinfectant will be charged.

For benzalkonium chloride, there are numerous hazards (please google for Wikipedia or other)

As already reported many reviewers, the power of the device is very weak. In 1998, there were my knowledge of the Stiftung Warentest rating Poor.

For eco-test years later there was a satisfactory mE (without evaluation of the cleaning performance). Where Me was determined that the humidification is weak. If the cleaning performance has also been tested, the result would mE failed Warentest more towards Foundation.

Here, air is blown by a fan on a water surface mE only. That's all. Because of all the dirty is blown into the air at the water surface, a sanitizer must be used mE.

Venta maintains mE that the device can purify the air. This may not be the device mE. Venta itself indicates that dust can be captured to 10Mikrometer. And even this creates the device is not sufficient. State of the art in the air cleaning is 0,3Mikrometer to 99.97% (HEPA H13).

The device is good in my opinion nothing is his money and not begin to value.

Suffice it to say: Venta maintains that one can not humid spaces by means of cold evaporation. Venta devices also unable to do this in my opinion. But I do not believe because of the principle of "cold condensation", but because the devices work extremely inefficient. If the Venta week by continuously running, the device will not make it in my opinion, to damp the room. I have a device that also works with cold evaporation and not an hour is my bedroom to over 70%. This device creates obvious in one hour more than Venta can ever reach.

For as much money as Venta demands for medium and large equipment, you get devices with sensors for temperature, humidity, dust and odors HEPA filter, activated carbon filter, etc. Venta has nothing. As is already clear that Venta mE achieved here extreme margins.

Originally Unfallkasse Post and Telecommunication:

"Even humidifier can become germ and fungus skidding The magazine Ökotest examined 2006 several of these devices. (Own Note: Was the Venta not it?) After eight weeks, an exuberant bacterial flora was evident in all the inner, permanently damp surfaces themselves. if they have been cleaned and disinfected exactly as specified by the manual.

The Federal Environment Agency in 2008 pointed out that it should be omitted because of the ... risk of microbial colonization on Humidifiers. Experts from the UK PT share the assessment of the Working Group of the Technical Committee Air impacts and work-related health hazards the German Social Accident Insurance. According to the current state of knowledge is an additional humidifying the air ... for health reasons does not make sense. "

Telekom, Postbank, Post: If you the specialist for occupational safety decreases the device, then it only does what it should.

Bacteria, germs can be multiresistant to my knowledge under constant exposure to disinfectants (as in principle Venta). Because the Venta device can not be mechanically cleaned aureichend (disk pack too closely), this can be dangerous in my opinion.
