HySapientia 24-litre air fryer oven summary

Where most air fryers are best suited to smaller households of two or three, this beast of a model from HySapientia can cater up to five people; a novel capacity for gadgets of this kind. Its oven-like body takes up a fair space on the counter, but what you get in return is 10 functions and an impressive 24-litre capacity with three tiers, so you can cook larger quantities or different dishes simultaneously.


For such a bulky appliance, it's relatively lightweight for lifting between its box and the kitchen countertop. The polished stainless steel body looks attractive, though it is easily marked with fingerprints.

It feels solidly built, and the accompanying accessories are extensive. Included are a pair of small silicone oven mitts, an oven rack, baking tray, rotisserie with a removable loading arm, air fryer basket, and crumb tray, which has a raised lip around it to contain any mess.

How easy is the HySapientia air fryer oven to use?

When unboxing this model, we found there was an excess amount of sticky tape attached to the packaging, which made it awkward to remove. The manual is clear and well written, and there's also a separate A2 sheet with cooking charts for various ingredients – though its enormous size is a bit impractical.

The attachments slot inside with ease, though the air fryer rack feels snug – so much so that you feel as though you might scratch the insides of the oven when you slide it in. We found the controls incredibly intuitive, and identifying each preset on the display is hassle-free and can be done without the manual.

It's a noisy machine, and there's a loud dinging sound that chimes every time you do anything. Adjusting the settings is a breeze though, and the LED screen also displays a heat warning for safety after the timer has finished.

Cooking results

The oven-like design of this air fryer means hot air can circulate easily around the basket during testing, which means you don't need to shake or turn the ingredients half-way through cooking.

Our chips were evenly golden and crisp, with a good seal and fluffy centre. The salmon was consistent in colour but not as browned as we'd hoped – five extra minutes of cooking would have resolved this.

Our aubergine slices were soft and golden brown, cooked for 10 minutes at 220C. Halloumi fries were also a success, both crisp and stretchy in texture.

How sustainable is the HySapientia air fryer oven?

While its two cardboard boxes can be recycled, there was plastic wrapping around the body of the appliance, two enormous chunks of polystyrene, and plastic around the various attachments – none of which were recyclable. There were unnecessary amounts of tape used. It also has a one-year warranty, which is short considering the price tag.

In testing, we found it was more expensive to run than most other models, costing 7.56p to operate for 10 minutes on the manual setting (based on a variable tariff of 31.8p/kWh). That said, it's a larger-than-average air fryer, so it requires more energy to get to temperature and cooks a larger quantity of food per run. You save on time over batch-cooking in a smaller model.


If you're a medium or larger-sized household looking to reduce your oven usage, this air fryer is an excellent alternative that scores highly on versatility, capacity and ease of use. Its size should be considered as some kitchens might struggle to store it, and improvements need to be made to the packaging to make it more sustainable. That aside, it produced impressive results in testing, and its array of accessories make it great value.
