An air fryer oven makes sense when you want trays, a front-opening door and more ways to cook than a drawer fryer offers. But the litre figure alone is a poor buying guide: a deep oven can swallow worktop space, while a roomy cavity may still reject your favourite tin. Start with the food and tray sizes you use most, then measure the space where the appliance will live.
For most households wanting one versatile worktop oven, the Ninja Foodi DT200UK is the strongest starting point here. Tefal’s 20L FW605840 is the smaller-capacity alternative, Tower’s T17122 gives you a 30L cavity and rotisserie, and HYSapientia’s HYS-AFO-05B is the unusual choice when two smaller sections matter. These are oven-style machines, not drawer air fryers.

Air fryer ovens compared
| Oven | Cavity | Useful feature | Best for | Check before buying |
|---|---|---|---|---|
| Ninja Foodi DT200UK | Not stated | two-level cooking | all-round worktop oven | Its approximately 50.5cm depth needs careful measuring. |
| Tefal Easy Fry FW605840 | 20L | 10 functions | 20L everyday choice | The 20L figure is cavity volume, not a promise that any roasting tin will fit. |
| Tower Vortx Platinum Xpress T17122 | 30L | rotisserie | large-capacity choice | Its larger body takes more permanent worktop space. |
| HYSapientia HYS-AFO-05B | 22L | removable divider | two cooking zones | Half-width trays are less useful for a large single dish; check the accessory set. |
Capacity is the maker’s cavity figure, not a guarantee that a particular roasting dish fits. Check the internal tray dimensions, rack positions and ventilation instructions for the exact model before ordering. The best choice depends on whether you need wide flat cooking space, a more modest cavity or separate cooking zones.
The four ovens in detail
Ninja Foodi DT200UK — The flexible family oven

Ninja’s DT200UK is a front-door worktop oven with air fry, roast, whole roast, grill, bake, pizza, dehydrate, reheat, toast and bagel modes. It can cook on two levels, with separate trays and an air-fry basket. That combination of racks and a front-opening door makes it more flexible for flat trays and toast than a drawer fryer.
Watch out for: The case is roughly 43.5cm wide and 50.5cm deep, before allowing the clearance the manual requires. It is not a compact answer to a shallow worktop. Nor should you assume every accessory is dishwasher-safe: Ninja distinguishes the basket and racks from the trays. See the maker’s model details.
Tefal Easy Fry FW605840 — A 20L oven for everyday trays

The FW605840 offers air frying, roasting, grilling, baking, pizza, toast and other settings in a 20L front-opening format. Tefal specifies three cooking levels, an air-fry basket, rack, baking tray and crumb tray. That makes it a practical option if you want oven-style access without moving to the largest cavity in this list.
Watch out for: 20L is still an oven, not a small drawer fryer. Measure your tins and counter first. Tefal says its cooking accessories should be cleaned by hand, so this is not the pick if dishwasher-cleanable racks are essential. See the maker’s model details.
Tower Vortx Platinum Xpress T17122 — A wide cavity with a rotisserie

Tower’s T17122 pairs a 30L cavity with a rotisserie and digital presets, including air fry, roast, bake, grill, toast and dehydrate. Choose it when the extra single-cavity space and rotisserie are features you will actually use, rather than paying for litres that sit empty. Its viewing window helps you check browning without repeatedly opening the door.
Watch out for: A large worktop oven still has rack and tray limits. Confirm your dish dimensions and the unit’s required clearance. Do not treat Tower’s advertised energy-saving percentage as a saving for every meal; batch size and cooking time change the result. See the maker’s model details.
HYSapientia HYS-AFO-05B — Two zones without two drawers

HYSapientia’s HYS-AFO-05B uses a removable divider in a 22L oven cavity. You can prepare two smaller dishes with the divider in place or take the divider out for a wider single space. The brand also supplies half-width accessories and a rotisserie, so the layout is different from an ordinary two-drawer fryer.
Watch out for: Check what fits on a half-width tray before choosing it over a single open oven. The accessory bundle has many pieces to store and clean. The maker’s own product information has inconsistent box-capacity wording, so check the exact supplied configuration with the seller. See the maker’s model details.
Oven style or drawer style?
Choose by how you load food
A drawer fryer is convenient for chips, wings and small portions you can shake. An oven-style fryer lets you slide in flat trays, watch food through a door and switch between toast, baking and roasting. That does not mean it will always crisp food better. A crowded shelf can block airflow, and a basket can be easier to toss partway through cooking. If a quick basket meal is your main use, start with our general air-fryer picks rather than buying an oven for unused functions. For a lower-cost drawer-style shortlist, our best air fryers under £100 compares capacity and layout before you pay for oven functions you may not use.
One cavity or two zones?
A divider can help keep two smaller dishes apart, but it reduces the width available to each. The HYSapientia makes sense if that flexibility will be used most weeks. For one pizza, a roast in a dish or a wider tray of vegetables, the Ninja or Tower’s open cavity is more practical. If you specifically want drawers, our dual-zone fryer guide covers that different format.
Size, trays and worktop clearance
Measure the appliance and the food
Check three measurements: external width and depth, usable tray width, and the headroom needed when you open the door or remove a hot tray. The Ninja’s roughly 50.5cm depth is a good example of why a photograph can mislead on a shallow counter. Cavity litres include air space; they cannot tell you whether your cake tin or roasting dish fits. Our air-fryer size guide explains why household size alone is not a reliable litre calculator.
Leave safe ventilation space
Use the exact manual’s clearance instructions rather than a universal centimetre rule. Keep the oven on a stable heat-resistant surface, clear of cupboards and curtains, and make sure the door can open fully. Plug it into a suitable wall socket as directed by the maker; do not stack several high-power cooking appliances on one overloaded extension. Electrical Safety First’s air-fryer advice covers plugs, sockets and basic checks.

Cooking results and running costs
A smaller cook may save energy; a larger one may not
A countertop appliance heats less space than a full-size oven, so it can be a sensible choice for one tray or a modest portion. But there is no fixed saving per use. A long roast, a full 30L cavity or two batches can erase much of the advantage. Which?’s air-fryer-versus-oven comparison found the strongest savings with small amounts and warned that batch cooking changes the calculation. Our wattage guide explains why the watt figure alone is not the cost of a meal.
Do not use presets as proof food is cooked
Presets are starting points, not guarantees: thickness, loading and rack position all change cooking time. Turn or move food if the maker instructs you to, and check the centre of meat rather than judging it by a browned surface. The Food Standards Agency’s cooking guidance is especially useful for poultry. For more everyday timings, see our air-fryer cooking-times chart and adjust to your appliance.
Cleaning and safe use
Front-door ovens give you more surfaces to wipe than a simple drawer. Look for a removable crumb tray and check whether racks, baskets and baking trays are dishwasher-safe separately; one machine can mix dishwasher-safe and hand-wash-only parts. Unplug and let it cool before cleaning. Avoid abrasives on coatings or door glass, and follow the manual for removing grease near the elements.
Greasy drips and built-up crumbs are worth dealing with promptly. Ninja’s instructions, for example, place the oven tray beneath foods that may drip. A rotisserie adds forks and a spit to wash, while two-zone kits add half-width trays to store. Our air-fryer cleaning guide covers routine cleaning without harsh shortcuts.
Which air fryer oven should you buy?
Buy the Ninja Foodi DT200UK if you want the most rounded worktop oven in this group and have the depth for it. Choose the Tefal FW605840 if a 20L cavity and everyday oven functions are enough. Pick the Tower T17122 for its larger single cavity and rotisserie, provided you have the permanent counter space. The HYSapientia HYS-AFO-05B is for someone who will actually use the divider and half-width trays.
Measure first, then confirm the exact accessory set, manual clearances and current seller terms. If your meals rarely need trays or toast, a drawer fryer is likely the simpler, easier-to-clean purchase.
Frequently Asked Questions
What is the difference between an air fryer oven and a drawer air fryer?
An air fryer oven has a front-opening door and usually takes racks or trays, so it is more flexible for toast and baking. A drawer model is often simpler for smaller foods you can shake. Compare usable tray space, not just litres.
Can an air fryer oven replace a full-size oven?
It can handle many smaller everyday meals if your dishes fit, but a full-size oven remains useful for large batch cooking, several trays or oversized roasting tins. Check your most-used cookware before deciding.
Is a 20L air fryer oven big enough for a family?
It depends on the size and shape of the food, not the litre figure alone. Tefal’s FW605840 has a 20L cavity and multiple levels, but a wide dish or large batch may still need your main oven.
Are air fryer ovens cheaper to run than conventional ovens?
They can use less energy for smaller portions because they heat a smaller space. Savings depend on cooking time, appliance power and whether you need extra batches; there is no reliable fixed saving for every meal.
Can I cook on two levels at once?
Some models support it, including the Ninja DT200UK and Tefal FW605840. Follow the maker’s rack and accessory guidance, and allow for differences in browning between levels.
Which air fryer oven suits two smaller dishes?
The HYSapientia HYS-AFO-05B offers a removable divider for two sections. Check that your dishes fit the half-width accessories; if you want easy-to-shake baskets instead, compare dual-drawer air fryers.
