The Hand Dryer is a device used to dry hands after washing them in a public or private bathroom. This appliance is essential for maintaining good hygiene and preventing the spread of germs and bacteria. In this section, we will explain the purpose of a hand dryer, the different types available, their advantages and disadvantages, how to choose a suitable one, and how to avoid bacteria when using it.
What is the purpose of a hand dryer?
The hand dryer is used to remove moisture from hands after washing. By drying hands, the spread of bacteria and germs through water droplets left on the skin is prevented. Additionally, by not using paper towels or cloths, paper consumption is reduced, contributing to environmental care.
What types of hand dryers are there?
There are different types of hand dryers on the market, each with its own characteristics. Here are the most common:
Hot air hand dryers
This type of dryer uses hot air to evaporate moisture from the hands. It is a quick and efficient option, as it dries hands in a few seconds. However, some studies suggest that hot air can contribute to the spread of bacteria and viruses in the air.
Cold air hand dryers
Cold air dryers use air at room temperature to dry hands. This option is slower than the previous one but is considered more hygienic, as it does not contribute to the spread of germs and bacteria.
High-speed hand dryers
High-speed hand dryers are a more modern and efficient option. They use hot air at high speed to dry hands in a few seconds. They are more hygienic than conventional hot air dryers and faster than cold air ones.
Paper hand dryers
Another option is to use hand dryers with paper. These devices dispense paper towels for users to dry their hands. This option is the most hygienic, as it eliminates the possibility of spreading bacteria through the air. However, it has a greater environmental impact.
Automatic hand dryer
This type of hand dryer is characterised by not having push buttons to activate the dryer itself, so by simply placing hands in the sensor, it will activate automatically until either you decide to remove them or it turns off by programming.
