This article will cover what an air fryer is, how it works, and different technologies that manufacturers use to make their air fryers stand out. Let’s get started:

What Is An Air Fryer?



An air fryer is a countertop appliance that circulates hot air around your food in order to cook it. Unlike a deep fryer, an air fryer uses little or even no oil too cook your food. Picture cooking your food with a blow dryer and you’ll get the concept. Because of using less oil, an air fryer is thought of as a new healthy way of cooking. The healthy benefits of this appliance is not only reducing risk of heart disease caused by saturated fat from cooking oil but also helping you to lower calorie consumption. Some people question if cooking with a very high temperature will cause cancer. Surprisingly, this oil less fryer is safe for health and does not increase risks of cancer.

Air fryers come in a variety of colors, sizes, shapes, and technologies so you can find the right air fryer that looks great in your kitchen and meets all of your needs. Air fryers can also bake, grill, and roast foods, making them a very versatile appliance that’s great to have in any kitchen.


How Does an Air Fryer Work?

Modern air fryers are a surprisingly simple design. They are usually a box or cylinder shaped appliance with a lid on the top. Inside the air fryer is a stainless steel wire basket with a drip pan underneath to catch oil and juices from the food. All you have to do is to place your food into the basket, apply a light coat of oil to promote a brown crispy texture, close the lid, set temperature and set a timer.

Most air fryers come with cookbooks that tell you the proper temperature and cooking time for each food you prepare. You just set your fryer to the right temperature and set a timer. The air fryer will instantly begin producing superheated air at the set temperature, and then its fan will circulate the hot air around your food. When the time is up, you will get nice, crispy, oil-less food that doesn’t have as many calories as you would get from foods fried in heavy oils.

For foods high in fat like chicken, most of the fat and grease simply drips off into the drip pan. Air fryers are a surprisingly effective and easy way to cook virtually any foods. In fact, you can even bake a cake inside your new air fryer!

Digital vs Manual Control System


There are several air fryers available in the market. The air fryers that come with manual temperature and time control are usually cheaper than those with digital touchscreen. For example, Philips HD9220 Airfryer is approximately $100 cheaper than Philips HD9230 Digital Airfryer  although both models have the same capacity.


Smart Program

Despite this unique feature, the GoWise air fryer is still among the most affordable air fryers in the market.


Smart Button Technology


This feature is found in the Philips HD9240 XL Digital Airfryer. You can save your presets much the same as your radio stations on your car radio.
