Why Hand Dryers Work

To put it simply, electric hand dryers allow you to quickly and effortlessly dry your hands when they are wet. You will most often find hand dryers in public restrooms that have a lot of people going in and out of them. There are several reasons why you always tend to see them in these places. In this article, we will go over how electric hand dryers work and why you see them so often in restaurants.

Where Can You Find Hand Dryers?

You will most often find hand dryers in office buildings, bars, restaurants and any other place that a large quantity of people will be using the restroom in. The main reason why so many of these places use hand dryers is because of the costs. Contrary to what people may think, electric hand dryers actually will save the businesses a lot of money over the long run.

The alternative to hand dryers is paper towels. Although you can usually purchase these very cheaply, especially in bulk, the cost to run an electric hand dryer is drastically lower than the cost of stocking a public restroom with paper towels over and over again.

Over the course of the year, a busy restaurant can expect to save as much as $3000 a year by ditching paper towels and instead relying on hand dryers in their restaurants. Now that we know the reason why we see these so often in restaurants, we will move on to talking about how they work.

How Hand Dryers Work

Hand dryers work by accelerating the evaporation process on your hands. If you have ever used one, you may have noticed that the moisture on your hands doesn’t fly off when you use the hand dryer. Instead, the hot air blows on to your wet hands, and they quickly dry.

The warm air allows the water to evaporate more quickly than room temperature or cold air does, which is why it is heated. If you want to speed up the process even further, you can rub your hands as the air blows on them. By rubbing your hands, you will thin out the moisture that remains on your hands which increases the surface area that the air will be coming in contact with.


There are many benefits to using a hand dryer which is why they are so common to see. If you run a restaurant, switching to air dryers will save you a lot of money over the long run.
