The best air fryers have gained popularity in recent years as the must-have, kitchen appliance. Not only are they convenient at quickly rustling up fried foods and delicious meals using very little or no oil, but also considered a healthier and safer alternative to traditional deep fat or pan frying. Plus, if you enjoy cooking tasty treats in no time at all, there are many best air fryer recipes to try out. 

Essentially, air fryers are mini convection ovens, and work by circulating hot air around foods inside to ensure evenly cooked results. In addition, the heat helps to cook food quickly and achieve that crispy texture that you would normally get from traditional frying methods. This is also safer to use without the risk of hot oil splashes or incidents.

However, if you’re considering buying this handy appliance, avoid this biggest mistake people make when getting an air fryer. According to Sam Milner, air fryer expert and co-author of The Complete Air Fryer Cook Book, this one mistake could cost you in the long run.

With that said, you may well want to find out what this big mistake is before hitting the stores for a new air fryer. Plus, beware of these 5 worst places to use an air fryer in your kitchen. 

The biggest mistake when getting an air fryer

There are several, common air fryer mistakes that anyone can make — such as overcrowding the basket, putting in the wrong things, or even not cleaning it the right way. 

However, this key mistake may not be so obvious, according to our expert. “The biggest mistake people make when getting an air fryer, is buying the wrong air fryer size,” states Milner. “There is the assumption that if an air fryer size is marketed as being for one or two people, that it's perfect for them.

But an air fryer marketed for three to four is perfect for one to two people because it allows them to cook their meat, potatoes and veggies at the same time. Whereas, the smaller one-to-two person ones would just be big enough for a meal for one, or just the meat for two people.”

A surprising, yet useful tip to bear in mind when buying an air fryer for your home.

What is the ideal air fryer size?

Depending on your needs, air fryers vary in size, shape, capacity and price. So what would be the ideal size to buy for long-term use?

“We recommend that you go to a size of air fryer that will fit in your kitchen and to visualize placing a whole chicken inside the air fryer along with sides,” suggests Milner. “Then, that is the correct size for you — even if you don’t like chicken, you will have plenty of room for full meals and sides.”

Another thing to consider when buying an air fryer is whether you have sufficient countertop space, and storage. Since air fryers can be huge, you’ll need to find one that is suitable for your kitchen. 

In addition, it’s not recommended to use them in crowded spaces, or under low-hanging cabinets. Air fryers need proper ventilation during the cooking process and placing it under a kitchen cabinet will restrict this airflow — which may cause the appliance to overheat. And while it’s fine to store them underneath cabinets when not in use, always move your air fryer to an open space to allow enough surrounding space to vent while cooking.
