AIR FRYERS have been hailed by many as a healthy way to cook quick meals.
The kitchen-top gadget uses roughly half the energy of a regular cooker, making it a bit of a money-saving hack.
And despite its name, it doesn't actually fry food.
It just recreates the crispiness of fried food, without the need for extra fat.
Some now fear the small cookers could be a health hazard.
However, the research around the popular fryers is still very limited.

One NHS doctor has revealed how dangerous air fryers are and when exactly they can become a hazard.
Posting to TikTok, said on the whole, air fryers are okay to use - as long as you're using them correctly.
Like non-stick pans, air fryers are covered in polyfluoroalkyl substances (PFAS), otherwise known as 'forever chemicals', he explained.
The toxic substances are found in drinking water and other everyday products such as food packaging, carpets, furniture and contact lenses.

According to the , the chemicals may be linked to some cancers, including endometrial, ovarian, pancreatic, breast, and throat.
Dr Karan said: "This is only really an issue if the air fryer is damaged.
"As long as you don't plan on eating the lining of your air fryer you will be fine."
You should try and minimise how much damage and scratching there is to the non-stick coating of your fryer so the chemicals don't get into your food.
When cleaning or collecting food from your cooking device avoid using abrasive scrubbing tools and use wood or silicone utensils and liners.
"And if you're really worried about the non-stick coating you can use a ceramic or stainless steel air fryer," he said.
How do air fryers work?
The appliance operates a bit like a convection oven.
Hot air is created by a heating element, and this is then circulated around the food by a fan.
The veggies or meat you put in there are held up in the basket, allowing the hot air to cook all sides of the food.
By using an air fryer as opposed to traditional frying, you can get your food crispy and browned without having to use much oil - though you might use some to stop your food from getting stuck.
