Air fryers have matured from a lockdown-era novelty into a standard UK kitchen appliance. The category is still crowded, but the buying decision has become clearer: choose the right basket layout and usable capacity before comparing presets or app features. A 9-litre dual-drawer machine can coordinate a complete family meal, while a well-designed 6-litre single basket is often faster, cheaper and easier to store for one to four people.
This guide compares five widely available models at different price points. It is an editorial assessment based on current UK specifications, manufacturer documentation and design trade-offs rather than a claim of hands-on laboratory testing. Prices and availability were checked in August 2026 and can change; treat them as reference points and compare current offers before buying.
Our quick recommendations
| Model | Capacity | Layout | Reference price | Best for |
|---|---|---|---|---|
| Ninja Double Stack XL SL400UK | 9.5L | Two stacked drawers | £269.99 | Large families with limited worktop width |
| Philips 3000 Series NA332/09 | 6.2L | Single drawer with window | £139.99 | Best balanced everyday choice |
| Instant Vortex Plus ClearCook | 5.7L | Single drawer with window | £99.99 | Best value and simple controls |
| COSORI TurboBlaze | 6L | Single square basket | £129.99 | Flexible low-temperature cooking |
| Tefal Easy Fry Mega EY8558G0 | 7.5L | Extra-large single drawer | £99.99 reference | Big portions on a budget |
Best overall: the Philips NA332/09 combines a useful 6.2-litre basket, viewing window and broad temperature range without demanding the space or budget of a dual-drawer unit.
Best for families: the Ninja SL400UK provides two independently controlled 4.75-litre drawers in a narrow, vertical format. It is the strongest option here when two foods must finish together.
Best value: the Instant Vortex Plus ClearCook offers the controls most people actually use, a practical window and enough capacity for a small household at around the £100 mark.
1. Ninja Double Stack XL SL400UK — best family air fryer
View the Ninja Double Stack XL SL400UK on the official Ninja website
Ninja’s Double Stack solves a genuine kitchen problem. Conventional dual-drawer fryers are very wide; the SL400UK places its two 4.75-litre drawers vertically, making the body approximately 28cm wide. It remains deep at about 47cm and tall at roughly 38cm, so measure the distance beneath wall cupboards as well as the available width.
Each zone can use a different time, temperature and cooking programme. Sync coordinates the finish time, while Match duplicates settings. The included racks create two cooking levels in each drawer, so four components can be cooked at once if airflow is not blocked. Six modes cover Air Fry, Max Crisp, Roast, Bake, Reheat and Dehydrate. Max Crisp reaches 240°C, which is useful for frozen breaded foods.
The main compromise is complexity. Loading four layers takes more planning than filling one broad basket, and food close to the upper heating area may brown sooner. The machine is also expensive and draws up to 2470W, although wattage alone does not determine energy use: short cooking times and heating a smaller cavity can still make it more economical than a full oven for appropriate portions.
Pros
- Two genuinely independent zones with a generous 9.5L combined capacity.
- Slim footprint for a dual-drawer appliance.
- Racks make complete family meals possible in one cooking cycle.
- Dishwasher-safe drawers and crisper plates simplify cleaning.
Cons
- High purchase price.
- Deep body can dominate a shallow worktop.
- Vertical racks require more rotation and attention for even browning.
Buy it if: you regularly cook separate mains and sides for four or more people and would otherwise run an oven plus another appliance.
2. Philips 3000 Series NA332/09 — best overall
View the Philips 3000 Series NA332/09 on the official Philips website
The Philips NA332/09 is the sensible middle ground in this comparison. Its 6.2-litre square basket has enough floor area for a small chicken, several portions of chips or a layer of vegetables, yet the appliance is easier to accommodate than a dual-zone model. The front window and internal light let you assess colour without repeatedly opening the drawer and releasing heat.
Philips lists 16 cooking methods, including air frying, baking, grilling, reheating, defrosting, dehydrating and fermentation. The 40°C lower setting is more useful than it sounds: it supports dough proving and gentle drying, while the normal high-heat range covers everyday crisping. RapidAir Plus describes the shaped basket and airflow system intended to circulate hot air around food.
The limitation is the single zone. A chicken and vegetables needing different temperatures cannot be independently controlled. A large basket can also encourage overfilling; crisp results depend on leaving gaps or shaking food during cooking. Nevertheless, a single broad basket is often more flexible than two narrow drawers when cooking a whole joint or baking in a suitable tin.
Pros
- Excellent compromise between capacity, footprint and price.
- Viewing window reduces unnecessary drawer opening.
- Wide temperature and function range.
- Removable dishwasher-safe parts.
Cons
- No independent second zone.
- Marketing claims around presets matter less than learning manual time and temperature settings.
Buy it if: you want one dependable air fryer for a household of two to four and do not need two temperatures at once.
3. Instant Vortex Plus ClearCook 5.7L — best value
View the Vortex Plus ClearCook on the official Instant website
Instant’s Vortex Plus focuses on fundamentals. The 5.7-litre drawer is large enough for a claimed 1.6kg chicken or around 900g of chips, though smaller batches will brown more consistently. ClearCook combines a window with an internal light, and the progress display plus turn-food reminder reduce guesswork for first-time users.
Its six programmes are Air Fry, Roast, Grill, Bake, Reheat and Dehydrate. That is a more honest and useful set than menus containing numerous food-specific presets that merely recall a time and temperature. At around £99.99, this model delivers most of the everyday benefit of more expensive single-basket machines.
Build and after-sales expectations should match the price. The official guarantee is shorter than some rivals, and the one-year coverage is worth weighing against a discounted premium model. There is also no second zone, app control or steam function. None is essential for crisping chips, reheating pizza or roasting vegetables.
Pros
- Strong price-to-capacity ratio.
- Clear window, light and useful cooking reminders.
- Straightforward interface with six relevant functions.
- Basket and tray are designed for easy cleaning.
Cons
- One-year manufacturer guarantee.
- Single-zone format cannot coordinate different temperatures.
- Large loads need shaking or turning.
Buy it if: you want a first air fryer that is easy to understand and costs close to £100.
4. COSORI TurboBlaze 6L — best for flexible cooking
View the TurboBlaze 6L on the official COSORI website
COSORI differentiates the TurboBlaze with a variable-speed DC fan and an unusually broad 30–230°C range. In practical terms, that gives it credible uses beyond high-temperature frying: proving dough, dehydrating fruit, keeping food warm and gently reheating leftovers are easier when the fan and heat can be moderated.
The 6-litre square basket is a good size for three or four portions and uses worktop space efficiently. Nine main functions are backed by manual controls, so the owner is not locked into presets. COSORI also provides a two-year warranty and a large recipe ecosystem.
Unlike the Philips and Instant models, there is no viewing window. You must open the basket to judge browning, and the touch panel takes a little familiarisation. The 6-litre capacity claim should not be confused with usable crisping area: dense piles of chips still need shaking and may be better cooked in two batches.
Pros
- Broad 30–230°C range and variable fan behaviour.
- Compact square basket with useful capacity.
- Two-year warranty.
- Good option for baking, proving and dehydrating as well as air frying.
Cons
- No viewing window.
- Single basket only.
- Nine modes add convenience but do not remove the need to adjust recipes.
Buy it if: you want a versatile single-basket appliance and plan to use lower-temperature functions regularly.
5. Tefal Easy Fry Mega EY8558G0 — best large single basket
View the Easy Fry Mega EY8558G0 on the official Tefal website
The Easy Fry Mega is built around one advantage: a 7.5-litre drawer in a relatively straightforward appliance. A wide single cavity can take bulky food that will not fit into either side of a split drawer, making it useful for a whole chicken, a cake tin or one large batch of roast vegetables. Tefal supplies eight presets and manual control from 80–200°C.
It is less technically ambitious than the other models. There is no window, independent zone or low-temperature proving mode, and the minimum 80°C setting limits gentle drying. However, simplicity can be a strength. If one large food is the normal use case, paying for synchronised drawers adds cost without improving the result.
Official availability has varied, so compare stock and warranty terms at reputable UK retailers rather than chasing an unusually low marketplace listing. The commonly advertised price near £100 makes it attractive, but only when backed by normal UK consumer support.
Pros
- Very generous 7.5L single drawer.
- Simple controls and eight presets.
- Strong value when available around £100.
- Better suited to bulky food than two narrow baskets.
Cons
- 80°C minimum temperature is less versatile.
- No window or dual-zone cooking.
- Availability and promotional pricing fluctuate.
Buy it if: you prioritise one large cooking cavity over independent zones.
How to choose the right air fryer
Choose basket shape before headline litres
Capacity figures are not directly comparable. For crisping, the basket’s floor area matters because food cooks best in a loose layer. Dual drawers provide flexibility, while a single square basket accepts larger items. Take the removable basket dimensions to the recipe or baking tin you expect to use.
Allow ventilation space
An air fryer moves large volumes of hot air and must not be pushed against a wall or operated beneath a low cupboard without the clearance stated in its manual. Measure width, depth and height with handles and control panels included.
Check coatings and replacement parts
Most baskets use a non-stick coating. Avoid metal utensils, aggressive scouring and aerosol sprays that the manufacturer does not recommend. A model with replacement baskets and crisper plates available from the brand is a better long-term purchase.
Do not buy on energy claims alone
Manufacturer savings are based on specific comparison recipes. An air fryer usually beats a full oven for modest portions because it heats a smaller chamber quickly; the advantage narrows when it is overfilled, run repeatedly or used alongside the oven. Compare the meal you actually cook, not the largest percentage on the box.
Final verdict
For most UK homes, the Philips 3000 Series NA332/09 is the best-balanced purchase: useful capacity, a viewing window and flexible temperature control at a mid-range price. The Ninja Double Stack XL justifies its premium for families that need two independent zones but lack worktop width. Budget-conscious buyers should start with the Instant Vortex Plus ClearCook, while the COSORI TurboBlaze is the more flexible choice for low-temperature cooking. Choose the Tefal Easy Fry Mega when one oversized basket matters more than additional technology.
Frequently asked questions
Is a dual-drawer air fryer always better?
No. Dual drawers are excellent for foods needing separate temperatures, but each compartment is narrower. A large single basket is often better for a whole chicken, baking tin or one broad layer of food.
What capacity does a family of four need?
Around 6 litres is a practical starting point for side dishes or smaller complete meals. For larger portions or cooking a main and side simultaneously, consider 8–10 litres across two zones.
Can air-fryer parts go in the dishwasher?
Many baskets and crisper plates are dishwasher-safe, but always check the model manual. Hand washing with a soft sponge can be gentler on non-stick coatings and may extend their life.
Are the prices in this guide guaranteed?
No. They are reference prices observed from official UK pages in August 2026. Promotions, colours and stock can change quickly.
