Air Fryer vs Food Dehydrator: How Different Are They?

Have you heard people talking about air fryers? You’ve probably heard a family member or friend mention them at some point because they’re a very hot kitchen appliance right now.

And what about food dehydrators? You may have heard mention of these appliances too.

When you’re not very familiar with either appliance, they can seem pretty similar. If you’ve been thinking about testing one out, how do you know which is right for you?

To help you discern the differences between an air fryer or food dehydrator, just keep reading below.

We’ll cover what they are, some similarities and differences, and a few advantages and disadvantages of each. After reading, you’ll have a clear picture of which appliance is right for you, so you can take the best one for your needs home!

What Is an Air Fryer?

If you’re like most people, you probably enjoy eating fried food. One thing you may not enjoy, though, are the health risks so often associated with consuming fried food.

Often times, fried food contains grease, which, as you can assume, can lead to a wide array of health problems if not eaten in moderation.

An air fryer aims to eliminate these health risks by frying food without having to saturate them in oil first.

What Is a Food Dehydrator?

The primary function of a food dehydrator, on the other hand, is to reduce the water content of foods like fruits and vegetables. Foods like these have a high water content, which, if left for an extended period of time, can result in the formation of bacteria or fungus.

If you want to preserve your food without having to worry about bad bacteria or fungus, you’ll want to think about getting a food dehydrator.
