Advantages and disadvantages of an air fryer

From starting my article I always discussed benefits, advantages, and many other key points but every product in this world has some upside and downside points. You are now very much enthusiast to know about the advantages and disadvantages of an air fryer. Let’s discuss this.

Advantages of air fryer

Do not take a large space: The air fryer is a small cooking convection appliance. They need only a corner of your kitchen countertop. If you compare it with your coffee maker, it is slightly bigger than but smaller than big size convection ovens.

Due to its small size, it has advantages. They could be easily transportable and can be stored in your storage area while not in use. I think most people do the same with their air fryer if they are not using it.

Use less oil for cooking: This is the main intent to buy an air fryer. These small devices use hot rapid air to cook food instead of messy oil. At the same time, a deep fryer needs a gallon of oil to submerge the whole chicken to fry.

But the air fryer needs only one tablespoon of oil to brush over your food depending on what you cooking.

Disadvantages of air fryer

Takes moe time: An air fryer needs much more time than a deep fryer. While both of them need to preheat their pans or container before cooking. But the air fryer heats its basket quicker than a traditional deep fryer.

Once the two reach their specific heat point, the deep fryer wins the race cooking. Take an example while the air fryer fries the French fries in 20 minutes at the same time deep fryer can do it in 10 minutes.

Cook in batches: If you are cooking for a large family or a small party, then an air fryer is not an ideal choice for cooking. The air fryer compartment basket is small and hot air should pass through the food without any hassle.

If you block the air by placing lots of servings at a time, then your food will be undercooked or not evenly from each side. So you have to cook in batches.

Technical problems: The air fryer is an electrical cooking gadget that comes with some period of warranty. But sometimes you may face some technical issues in your air fryer.

Sometimes they are not working for power circuit problems. The buttons also do not work properly while you adjust time and temperature. Sometimes air fryer emits blue smoke from the exhaust fan etc. You should hire a repairer for this problem.

Need extra air fryer accessories: Your air fryer comes with a basket and pans and other accessories included in the box. That is enough for air frying but if you trying something different with it. Then you have to buy sme extra accessories for that unit.

If you are trying to bake, grill, roast. you need the baking pan, and grill pan and pay for extra.

Which is not justified with the investment in air fryers. In that budget, you can buy two deep fryers. So air fryer manufacturers should include extra accessories with the air fryer units.

A little bit expensive: If you are looking for a premium digital air fryer, you have to pay more than $100 like a Philips air fryer. But you will not find any more extra features than a LED illuminating display, dishwasher safe, and some extra accessories.

But I would suggest there are a lot of cheap air fryers under $100 and also they are durable and featured with a lot of functions.

From the above air fryer Pros and Cons competition, if you found your recommended features in air fryers then definitely go with an air fryer.

What should you consider when buying an air fryer?

Before going to buy an Air Fryer you should follow the air fryer buying guide and some major things to consider s. it will help to choose the best air fryer from many options.


Before you go to buy it you should ask yourself “What do I cook in the fryer and how many members in my family because there are different sizes of air fryers available for all types of people’s needs.

The smaller unit is only 1 to 3 QT capacity which is the best air fryer for one person. And the medium units are 3 – 6 QT, which is best for a small size family.

If you like small parties or you have a big family, then you should go with a large-size air fryer unit. At the last, I would always suggest going with large units never going with a small size air fryer.

Because big size offers you cook in varieties with air fryer accessories but in smaller units, you could not do such types of experiments with your foods.


You need to make sure that your kitchen outlet supports the watts consumption of your air fryer will use. Your kitchen outlet should support 800 watts to 1500 watts that a standard air fryer typically uses.

The more watts an air fryer has, the higher temperatures it will reach & quickly it will re-heat the oil if you have added up frozen food like frozen peas or meat to the grease. Air Fryers are available with wattage levels of up to 1800 watts & more


The temperature settings of your air fryer can have a decisive effect on getting out the final result you want.

Mostly, air fryers cook food well when the temperature is over 400 degrees F. Higher temperatures have the advantage of cooking food more quickly.

Batter coatings and baked goods also won’t absorb as much grease if they are cooked for a shorter period at a higher temperature but ensuring the machine has proper control that will help you cook at the right temperature.

The presence of indicator lights and an integrated timer will simplify the cooking process.


The maximum of electricity almost every air fryer with 1500 wattage can consume is not more than 1 unit a day. But varies this figure in the small size air fryer.

High power watts mean, it can heat up easily in minutes and cook your food in less time.

In the case of cooking for 30 minutes in an air fryer, the maximum electricity that will be consumed will only be half unit of electricity a day.

Air Fryer takes upmost 20 minutes to complete household cooking needs.


Firstly, look out for a well-insulated air fryer that has a cool-touch hand grip so that your hands don’t get burned while pulling out the basket.

Secondly, the base of the machine should be a non-slip foot so that the machine doesn’t slip off, locking lid, and exterior basket control. Be ensured that the air fryer has an automatic shut-off to prevent over-cooking of food.

Some frequently asked questions about air fryer problems

1. Should I add my ingredients before or after preheating?

Preheating is highly recommended for the best result. If you do not preheat your unit, it takes much more time than usual frying. As a result, your food will be over burnt or undercooked. So always try to preheat your air fryer for 5 minutes at 400° F.

2. Should I toss my fries in the mid of cooking?

The answer is yes, the air fryer uses hot air blowing by a strong fan around the food ingredients inside the air fryer basket.
So the hot air crisps the upper part of the food but not the lower portion. If you toss it in the mid of cooking, the whole portion of the food will cook evenly from each side.

3. Should I add oil to my food?

The air fryer claims that it does not require oil to cook food. But using a tablespoon of oil brushing the upper layer crisps the fries more evenly and increases the taste. So you should use a little oil in your food while cooking in an air fryer.

4. How do I pause the unit so I can check my food?

Almost every manufacturer has featured their air fryer with auto-pause technology. When the cooking basket is opened in the mid of cooking, It automatically timer stops and starts after placing the basket timer starts from the pause time.

5. My air fryer emits white smokes

Due to cooking high-fat food or using excess oil in your air fryer. Extra fat or oil is stored in the bottom basket of your air fryer. With the increase in temperature, the fat or oil reaches the evaporated states and produces white smoke. To prohibit the smoke use some water at the bottom of your air fryer.

6. My air fryer emits blue smokes

These smokes are maybe the red signal to stop your air fryer. If your air fryer emits blue smoke that may be due to the electric short circuit inside the control panel. You should immediately be plugged out and hire a professional repairer.
