First, let’s know the working principle of the hand dryer: when induction, the motor inside the machine rotates rapidly to suck in air and then blow out high-speed air. However, the sanitary environment in public places is more complicated, and the air contains a lot of bacteria. If it is blown out directly, it will definitely blow all the bacteria in the air to the hands. At this time, the hands will be dirtier than before washing hands. So the key is how to clean the inhaled air, which depends on the filter inside the machine. Now most hand dryers are equipped with filters.
WZWIYI High-speed Jet hand dryers are equipped with filters, which can capture 99.95% of particulate matter, including bacteria and viruses, from the airflow inhaled in the bathroom, and then blow out clean air to dry your hands.
Secondly, it is necessary to pay attention to the daily maintenance of the machine, such as cleaning the filter screen, treatment of the sump, and external wiping are all worth noting.

Maybe you’ll say that it is good to wipe your hands with a paper towel on public. But, when it exposed in public, or if it is placed in a relatively humid place for a long time, it has a certain amount of bacteria on the surface is naturally rough It will become the best breeding ground for all kinds of bacteria, and you will never be able to “clean your hands”.
