Air fryers can simplify weekday cooking, but the wrong model may become an expensive appliance that takes up worktop space without fitting your routine. Capacity figures, cooking modes and energy claims can also be presented in ways that make comparison difficult.
Before choosing from the wide range of air fryers, look beyond the headline features. The most useful questions are: how much food will you cook at once, do you need separate cooking zones and can the parts be cleaned without unnecessary effort?
A large litre figure does not always mean you can spread food across a large, even cooking surface. A tall basket may hold plenty of volume but provide limited room for chips, vegetables or chicken pieces to cook in a single layer.
For family meals, compare the basket layout as well as total capacity. A large capacity air fryer with one wide drawer may suit a roast or traybake, while a dual-drawer design may be more practical for cooking a main and side separately.
A 4-in-1 air fryer, 6-in-1 air fryer, 8-in-1 air fryer or 10-in-1 air fryer may list several programmes, but many rely on the same heating and fan system. Presets can make operation easier, yet the useful measure is whether the appliance supports the food you regularly prepare: air frying, roasting, baking, grilling, reheating or dehydrating.
Check the actual temperature range, timer and cooking instructions rather than selecting a model solely because it has a higher function count.
An appliance that is difficult to wash may be used less often. Look for removable baskets, non-stick surfaces and clearly stated dishwasher-safe components. Also measure the appliance before ordering. Air fryers need clearance around air inlets and exhaust vents, and steam models require additional care around the steam outlet.
A compact air fryer or portable air fryer can be convenient in a smaller flat, but confirm that its capacity matches your normal portions. A large model may be unsuitable if it cannot remain safely positioned on your worktop.
As a general guide, a 4–5 litre appliance can suit one or two people, while 6–9 litres may be more suitable for couples, families or batch cooking. These are practical guidelines rather than fixed rules, as basket shape and portion size vary.
A dual zone air fryer uses two independent compartments, allowing different temperatures and cooking times. Look for a synchronisation function if you want both foods to finish together. Some flexible models let you remove a divider and create one larger cooking area, which is useful for a whole joint or larger roasting dish.
Review the appliance’s temperature range and wattage, but do not use wattage alone as a measure of cooking performance. Higher power can affect heat-up time and electricity use, while cooking duration, load size and food type also matter.
If you are considering a steam air fryer, check whether it has a dedicated water tank, how long the tank runs and how the steam system should be cleaned. Steam can help retain moisture during certain cooking programmes, but it adds another component to maintain.
An air fryer oven may offer shelves or a larger cavity for baking and roasting. This can provide flexibility, although it may need more worktop space than a drawer-style model.
Look for clear information on food-contact surfaces, removable parts and the manufacturer’s cleaning instructions. A dishwasher-safe air fryer can reduce washing-up, but check which components are actually dishwasher-safe; the main electrical unit must not be immersed.
Energy claims should be read carefully. For example, a manufacturer may report lower energy use than an oven under a particular test involving specific foods and cooking times. Actual household costs depend on the appliance’s power rating, cooking duration, load and your electricity tariff. Using an appropriately sized air fryer instead of heating a full oven may reduce energy use for some meals, but it is not a guarantee for every recipe.
Why This Fits Their Persona: Its 5-litre format suits individuals, couples and small households looking for a straightforward worktop appliance without the footprint of a dual-drawer model.
It uses a clearly stated 5-litre capacity and four defined functions rather than relying on a long list of overlapping presets.
Digital touch controls; air fry, roast, bake and reheat modes in a compact design.
Why This Fits Their Persona: The 10.4-litre format is suited to households that want to prepare family portions or switch between two meals and one large cooking area.
Its removable divider lets you choose between two 5.2-litre zones and one 10.4-litre MegaZone, addressing the limitations of a fixed basket layout.
Seven cooking functions; drawer, divider and crisper plates are described as non-stick and dishwasher-safe.
Why This Fits Their Persona: This model is designed for cooks who want air frying alongside steaming, baking, roasting, grilling and reheating in a 7-litre appliance.
The dedicated 1.4-litre water tank and listed SteamFry function make the steam feature more specific than a generic multifunction label.
1700W power; adjustable temperature up to 200°C and timer up to 90 minutes.
Why This Fits Their Persona: Two 4-litre baskets allow a family to prepare different foods at separate settings, while SyncFinish is intended to coordinate serving time.
The separate basket capacities and independent controls make its dual-zone design clear rather than implied by a high total litre figure.
Eight listed functions; SyncCook and SyncFinish support same-setting or coordinated cooking.

Accessories can expand what a suitable appliance can do, but check the internal measurements before buying. A cake pan, pizza pan, rack, skewers, silicone mat or egg-bites mould is only useful if it leaves adequate room for air circulation.
The six-piece accessory set listed for 3.5-litre appliances includes baking, roasting and grilling components. Confirm compatibility with your specific basket, particularly if it has a divider or unusually shaped drawer.
They can use less electricity for some smaller meals because they heat a smaller cooking area. Running cost depends on wattage, cooking duration, portion size and your tariff. Treat manufacturer comparisons as test-specific rather than a universal saving.
Lifespan varies with frequency of use, cleaning, storage and component wear. Follow the manual, avoid abrasive utensils on non-stick surfaces, keep vents clear and do not immerse the main unit. Check the available parts guarantee before purchase.
Use a stable, heat-resistant surface with clearance around the air intake and exhaust. Keep it away from flammable materials and do not block vents. Steam models need additional space around the steam outlet and all hot drawers, baskets and chambers should be handled with suitable protection.
