One of the main reasons why air fryers become so popular is that they can cook food very fast while also using much less oil compared to regular frying. But a lot of nutrition and safety experts warn that it is not appropriate to use them all the time as a substitute for a traditional oven. Air fryer advantages aside, there are still some health, safety, and even the quality of cooking issues concealed behind the idea of totally swapping your oven with one. Here are certain reasons why experts have warned people who choose air fryer instead of an oven.
High heat can form harmful compounds

On many occasions air fryer heating temperature is very high, thus it is very likely to lead to the formation of substances that are considered to be cancerogenic.
Nutrient loss from overcooking

Since air fryers’ cooking method is very fast and involves hot circulating air, it could result in drying of vegetables and even lean meat. This sometimes causes nutrients to be depleted more than in other ways, like baking.
Some models might release harmful fumes

The non-stick surfaces, which commonly contain PTFE or PFAS chemicals, can deteriorate at high temperatures that may release unhealthy compounds on the food in the case of being scratched and overheated.
Food safety risks from improper cooking

Also, if the heat is not uniformly distributed or the basket is crowded too much, it will result in the food being poorly heated, thus there will be undercooked meat and bacteria risks more specifically if the internal temperature is not checked.
Grease and residue build-up can be dangerous

Some of the experts have also stated that the particles, such as small bits of bread, oil splatters, and food leftovers that are inside and not visible, can accumulate very quickly, and if they are repeatedly heated without being cleaned thoroughly, they could become a source of fire or bacteria.
Higher fire risk if misused

There is also the risk of air fryers overheating and therefore playing a role in the outbreak of fires, especially if they are filled too much with food or placed too close to walls or other flammable materials.
Some devices have quality issues

Among other things, recall and safety notices of certain models indicate that a problematic design or electronics issues may be the reasons why the device vents excessively and causes fires.
Not ideal for large or certain foods

Although air fryers perform well with small amounts of food, it is very difficult to do a few tasks that an oven can do because it provides even heat distribution.
Potential for plastic or microplastic exposure

The least expensive versions of the fryer or parts made of poorly processed plastic may emit fine plastic particles or smoke when used over and over and heated.
Frequent cleaning is essential

In contrast to an oven, the limited space and the strong fan mean that the food that remains in the air will be recirculated and will settle everywhere, and if you do not clean them, there is an increased risk of health problems.
Uneven cooking can affect taste and texture

The principle of an air fryer is not the same as that of an oven; thus, in certain instances, the food may turn out to be dry or uneven.
Higher electricity use in some situations

If the meal is a big one or you want to do several batches, then the amount of energy consumed would be very high, which makes the anticipated savings non-existent.
Environmental impact and waste

Using small electric appliances regularly contributes to higher household energy consumption, and this,s together with the fact that these appliances will eventually become e-waste when they wear out, is very bad for the environment.
