Our Verdict
This is one of the largest air fryer ovens we’ve seen and its huge capacity means you’ll get crispy results no matter how much you cook. But you’ll need plenty of space to house it and if you’re only cooking small amounts of food, it seems like overkill.
Air fryer builds have trends, like everything else, and right now, air fryer ovens are having a moment.
While air fryers — which are really just mini convection ovens — started out as fairly compact appliances with a single slide-out drawer, larger models are becoming more common. Air fryer ovens, as they are called, have a larger capacity and, in fact, resemble the built-in oven in your kitchen, with a number of rack heights, internal lighting and a drop-down door that has a viewing window. .
These countertop ovens will need a correspondingly large amount of space. That’s certainly the case with the massive HySapientia 24-Quart Air Fryer Oven, although it’s a versatile cooker, even boasting a rotisserie function.
HySapientia is a brand specific to air fryers. You can buy its home appliances in the United States and the United Kingdom.
Design and build
- 10 presets
- Stainless steel construction
- Viewing window and interior lighting
One of the best things about the HySapientia Air Fryer Oven is its construction. It’s made almost entirely of stainless steel and other food-grade metals, which is a nice change from the plastic air fryers we tend to see. Still, it feels a bit flimsy and certainly not as sturdy as a microwave, for example.
As you would expect from a 24 liter capacity device, it is huge, with dimensions of 16.8 x 18 x 16.5 inches/ 41.4 x 37.5 x 37.5 cm . It will need 4 inches/10 cm of clearance around it, so you won’t be able to keep it flush with the tiles. But it looks great on the counter, because its shiny steel means it’s not a black monolith that sucks up the light like so many competitors.
There’s a large viewing window in the door and an internal halogen light that you can turn on, so you can monitor what’s cooking inside.
It is controlled via a wheel and a series of six buttons. The screen shows 10 presets, as well as the time and temperature.

Presets include toast, bake, fish, dehydrate, broil, air fry, defrost, steak, pizza and rotisserie. But you will have to go back to the manual to decipher them since dehydration is represented by a carrot and grilling by a chicken leg. You can also choose a high or low fan setting.
You choose a preset using the dial and while it’s simple to understand, it’s annoying to use. For starters, the device beeps with each adjustment, so turning the dial is accompanied by a loud beep. whore ! whore ! whore ! whore ! whore ! when it reaches each preset, time or temperature option. I was hoping to find a mute option in the manual but no luck.
Second, with so many preset options, a dial isn’t the best option, as you’ll spend a lot of time turning it back and forth (to the sound of maddening beeps). A touch screen would be much faster and more precise.
Once you’ve chosen your preset, you can then adjust the time and temperature – again, using the dial. But it is not possible to choose a duration and temperature independent of the setting. This means that for everything except dehydration, you can only choose a cooking time of up to an hour. Dehydration gives you 240 minutes, but heat is capped at 70oC/160oF. Overall, the device has a maximum temperature of 230oC/450oF.
To take advantage of the huge capacity, I decided to roast some lamb. The suggested time on the package cooking instructions was two hours. I knew the air fryer oven would take a lot less time, but that still meant coming back to reset the unit for a second cooking period. This is not ideal for an air fryer oven of this size.
Likewise, the shortest cooking time is 5 minutes, so if you want to reheat something that won’t take a full 5 minutes, you’ll need to hover over the device until it looks ready.
A final word on screen. When you turn off the air fryer oven, the display says OFF – all the time. So you’ll come into the kitchen for a glass of water in the middle of the night and the air fryer will still show an OFF light to remind you it’s off.

The air fryer oven comes with a variety of accessories including a mesh air fryer basket, roasting pan, crumb tray, oven rack, drain rack, rotisserie spit and a silicone oven glove. It has everything you’ll need to make the most of its various functions but then you’ll need to find a place to store all the items. It is not recommended to place them above the appliance and, moreover, your cooking will be accompanied by the noise of the metal trays colliding.
Performance and Features
- Cooking time from 5 to 60 minutes (except in dehydration mode)
- Crispy results
- Cheap to cook entire family meals
One of the reasons to buy this device is its versatility. You can do everything with it, from making toast to baking, defrosting pizza or making roast potatoes. If you find the size of your current air fryer frustrating when cooking, that won’t be the case with HySapientia’s 24 Quart Air Fryer Oven.
But the downside is that if you just want to heat up a few fish sticks for your child’s dinner, you’ll be heating up a lot of empty space and that seems excessive.
It’s an 1,800W device, which means that with the current capped price in the UK it will cost you 26p or less to cook for half an hour. You can find out how much your tariff will cost by using an online energy calculator.
But its capacity has a money-saving advantage. If you have a smaller pull-out air fryer, you will only be able to cook one dish at a time, such as chips or chicken nuggets.

In this appliance, you’ll have room for both, or more, meaning you can cook an entire meal at once for much less than it would cost in your built-in oven.
There is a learning curve to using this air fryer oven. Luckily, it comes with a recipe book that offers recipes for each preset. However, they tend to focus more on full recipes rather than baking guides, which means they contain lots of phrases such as: “When the mutton is cooked to your liking, take it out.” . There are also some translation oddities scattered throughout the text.
The air fryer oven is easy to install. Simply remove the packaging and stickers and wash the accessories in warm, soapy water. Then you are ready to go.
I tested the air fryer oven for three weeks, using it in place of an air fryer and oven. What impressed me the most was how crispy the food cooked in it was, probably because the large cooking space allows plenty of hot air to circulate. From crispy, melty toast to crispy roast potatoes, gnocchi, roasted butternut squash, frozen pizzas and chips, almost everything I’ve cooked in it has turned out well – and everything has been cooked a lot faster than in a built-in oven.
However, I didn’t find the presets particularly useful and until I calculated the times and temperatures, I spent far too much time staring out the cooking window, trying to decide when a dish was ready. It was particularly difficult to judge when a lamb shoulder was done. If you want to cook a roast or other large piece of meat, we suggest investing in a meat thermometer to ensure perfect cooking.
Nevertheless, the lamb was a success, the meat juicy and the fat crispy.

After cooking, I found the interior and accessories easy to clean, except for the window. It is a double layer, but water and oil can get stuck between the two panes. You will need to unscrew the interior glass panel to clean it thoroughly.
Pricing and availability
The HySapientia 26QT/24 Quart Air Fryer Oven is available on Amazon US, with an MSRP of $199.99. However, at the time of writing, it’s available for $159.99, which is what we think you should pay for it.
It’s a similar story in the UK, where its full price on Amazon UK is $199.99, but the current deal is £159.99.
It compares favorably to the price of other large-capacity air fryers, such as the Tefal Easy Fry Air Fryer Oven and the Ninja Foodi Max Dual Zone. For its construction, its enormous capacity and its functionalities, its price is very attractive.
Should you buy the HySapientia 26QT/ 24 Liter Air Fryer Oven?
Due to its size, it is a niche product. You’ll essentially have a second oven in your kitchen, which isn’t for everyone. But if your current air fryer is too small and you want more cooking space – especially if you use its rotisserie function – it’s great value, easy to use and will deliver amazing results crispy. All we’d like to caution is that the control panel could be faster and less of a nightmare to use.
