Try making some chips in an air fryer without oil and tell me how satisfactory you think the end result is.
Not quite as satisfactory as with a tiny coating of oil, but not uneatable. Same with 'roasted vegetables' cooked in a conventional or fan oven - oil is not essential, but produces a more satisfactory result. However, as I've said, unlike 'real' frying (shallow or deep) it is primarily the hot air within an oven (whether 'blown' or not) that does the cooking, even if there is a tiny amount of oil present, whereas with 'true frying' it is actually the hot oil/fat in contact with the food which primarily does the cooking.
Same as a fan oven. Why not call a fan over an air oven?
They might well have coined that term, but clearly didn't. In fact, they tend to be called "convection ovens" these days, which id pretty close to "air oven".
At the end of the day, common names for things don't always appeal to one's own sense of logic.
Indeed - as I wrote, despite our use of things like "roast beef", "roast vegetables" and "nut roasts", it's really all 'baking', since very little true roasting is done these days. It's all very inconsistent, since we also have ('correct') 'baked apples', 'tray bakes' etc
Nobody is being defrauded by the name "air fryer" and it's a lot more concise than "countertop compact fan oven".
I'm not sure that "defrauded" is the right word, but an awful lot of people seem to think that what they are doing is, in some way, more like true frying when they do it in one of the small ap;liances than when they do exactly the same thing in a 'full-sized' oven - so maybe confused or misled, rather than 'defrauded'.
To try and keep this vaguely on topic, my air fryer seems to do a good job of containing cooking fumes.
They do. They presumably have to be relatively air-tight in order to make them reasonably efficient?
I made the effort to "plumb in" our recirculating cooker hood recently and this makes a massive difference to indoor air quality. If only I could convince the Mrs to actually turn the bloody thing on every time.
I'm sure that's true, but there can be downside. Most of our cooking is done on a gas (LPG) Aga,, which has a flue in continuity with the oven cavities. As a result, it's far from unknown for oversight on our part to result in food items being 'burnt to a cinder', without the slightest 'giveaway smell', since all the smells and smokes had, literally, 'gone up the chimney' - as was this recent case with some croissants
