Hand dryer is not quite safe
The idea that hand dryers in public toilets very hygienic, it is quite understandable. However, several studies, however. Fair must be noted, however, that there are different study results. Exchange studies of paper towels, like hand dryer - manufacturers were given in order.
- Scientists at the University of Westminster and the University of Leeds, for instance, in their studies to the result that hand dryers are not hygienic. In both studies, it was noted that the hand dryers are more unhygienic, the more the air flow is.
- The Problem with hand dryers is that they stir up with their enormous heat-ray only pure air. The hand dryer is spinning with the air flow of bacteria through the air. To make matters worse, especially in public toilets a lot, not always harmless bacteria are. These bacteria are often also on the hands. Removed the bacteria, when the hands are very thoroughly washed be. This doesn't happen often.
- The wet be held, only superficially cleaned hands under the hand dryer, does not dry the device with just the skin. Due to the strong heat flows are also in the hands of the remaining bacteria to be thrown through the air. The more modern and more powerful the tested device was, the more bacteria are whirled through the air. A compressed air dryer flinging around four times more Bactria through the air than a simple heat-drying and 20 times more than ordinary paper towels.
- Particularly fatal to The bacteria flying up to two meters wide and were after ten minutes still in the air. Ultimately, it means that you might after Drying more bacteria on hands than the hands wash.
- Dyson, the largest manufacturer of compressed air dryers, holds the result, however, is unrealistic because the study conditions are not the actual realities. The subjects in the Westminster University study wore gloves, which were pre-fitted with Laktobakterien. Then she felt the gloved hands under the hand dryer without having them pre-washed. A counter-study that was given by Dyson in order, were accordingly less dramatic.

Sometimes even thorough hand washing is not. There are occasions, as it is strongly recommended that hands be disinfected.
