When brainstorming ideas for this weeks blog post, I came upon an article that discussed several issues with modern hand dryers. These dryers are meant to reduce the amount of bacteria spread between users by releasing bursts of hot air onto users hands. However, several studies show that these new bathroom gadgets are causing more harm than good.
Researchers got a real surprise when they counted the bacteria left on the fingertips after using these new drying methods. When washing hands with conventional methods by using paper towels or continuous-loop cotton towels, researchers found that bacterial count was reduced by about 45–60 per cent. But when washing, and then using a warm-air dryer actually increased the bacterial count by an average of 255 per cent. This then lead me to question, “How could drying your hands increase the number of bacteria on your skin?” When examined more thoroughly the researchers found out the answer to my question. The solution was that the bacteria that was already inside the warm-air dryers, due to the warm moist environment, is spread when the air passes through the nozzle onto the user’s hands or arms.
Along with this information, I too became critical of these air hand dryers f0r several other reasons. First of all, these machines are loud, really loud, and after your ear drums have ruptured you are often left with moisture still on your hands, which requires you to enter round two with this ear deafening machine. Secondly, there is often a single air hand dryer located in bathrooms and this can lead to awkward lines which nobody enjoys. Finally, these dryers are expensive. Infact, a new Dyson Airblade Hand Dryer(pictured above) retails at $1,199.
Overall, I personally am unable to discern who would fund the purchase, use, or installment of these new air hand dryers. Not only do they lack functionality, they also have several deficiencies that cannot convince me that they are worth the lofty price tag that they are paired with.
