Best Air Fryers — Complete Buying Guide
Choosing the right air fryer can feel overwhelming with hundreds of models on the market. This guide cuts through the noise — what size you need, single vs dual-zone, wattage and UK running costs, the features worth paying for, and what to check before you buy.
Quick Answer: Which Air Fryer Should You Buy?
For most UK households of two to four people, a dual-zone basket air fryer of around 7–9L is the best all-rounder: it cooks a main and a side at the same time, at different temperatures, and finishes them together. If you live alone or as a couple, a 3–5L single-basket model is cheaper, smaller on the worktop and plenty for everyday meals. Large families and batch cooks should look at 9L+ dual-zone models or an oven-style air fryer with racks.
Everything below explains how to narrow that down to a specific model — size, type, wattage, running costs, the features that matter and the ones that are mostly marketing.
What Size Air Fryer Do You Need?
Capacity is the decision that matters most. Too small and you end up cooking in batches while the first batch goes cold; too big and you pay more, lose worktop space and heat air you don’t need. Manufacturers quote the total basket volume in litres, so for dual-zone models check the size of each drawer, not just the combined figure.
| Household | Capacity | Best type | Good for |
|---|---|---|---|
| 1–2 people | 2–4L | Single basket | Snacks, sides, two portions of chicken or fish, reheating |
| 3–4 people | 5–7L | Large single basket or dual-zone | A main plus chips in one go, family midweek meals |
| 5+ people | 8L+ | Dual-zone or oven-style | Full family meals, batch cooking, larger joints |
Not sure where you fall? The Portion & Shopping Calculator scales recipes to the number of people you actually cook for, which gives you a feel for how much food your basket needs to hold.
Basket vs Dual-Zone vs Oven-Style
There are three main designs on sale in the UK, and each suits a different way of cooking.
| Type | Pros | Cons | Best for |
|---|---|---|---|
| Single basket | Crispiest results, compact, cheapest, easy to clean | One temperature at a time; small sizes mean batch cooking | Couples, small kitchens, snacks and sides |
| Dual-zone (two drawers) | Two foods at different settings, finished together; flexible | Wider footprint; each drawer is smaller than the total suggests | Families cooking a main and a side |
| Oven-style | Racks, more flat space, viewing door, often rotisserie | Usually less crisp; more parts to clean; bulkier | Batch cooking, dehydrating, larger households |
If you mainly cook chips, wings and anything breaded, a basket model gives the best crunch because the food sits right in the airflow. If you regularly cook a full meal in one go, dual-zone is the bigger quality-of-life upgrade.
Wattage and UK Running Costs
Most basket air fryers draw 1,400–1,800W, and larger dual-zone models can draw more when both drawers run. Wattage mainly affects how quickly the fryer heats up and recovers when you open the drawer; it should be matched to the basket size rather than chased for its own sake.
Running costs are where air fryers shine. At the Ofgem price cap for October–December 2026 (26.32p per kWh for electricity on a typical Direct Debit tariff), a 1,500W air fryer running flat out for 20 minutes uses at most 0.5 kWh — about 13p. In practice it uses less, because the element switches off and on to hold temperature. Our worked example in Air Fryer vs Oven: Real UK Running Costs puts a typical meal at roughly 15p in an air fryer against around 45p in a conventional oven.
Features That Matter (and Ones That Don’t)
Worth paying for
- A “finish together” or sync setting on dual-zone models, so both drawers end at the same time without you doing the maths.
- Dishwasher-safe basket and crisper plate. You will clean it far more often if cleaning is easy — see our maintenance guide.
- A temperature range up to at least 200°C, with fine control in 5–10°C steps for things like reheating and dehydrating.
- A viewing window or light if you like checking food without opening the drawer.
- A shake reminder — a small thing that makes chips and wings noticeably more even.
Mostly marketing
- Long lists of presets. Most people use two or three and set the rest manually. The Cooking Time Calculator does the same job for any food.
- App control. Handy for some, but you still have to be there to load and shake the basket.
- Very high maximum temperatures beyond what you will actually cook at.
Non-Stick Coatings and Safety
Most air fryer baskets use a PTFE-based non-stick coating. It’s considered safe at normal air-frying temperatures, but it does wear: avoid metal utensils, abrasive scourers and aerosol oil sprays, and replace a basket that is badly scratched or flaking. If you would rather avoid non-stick altogether, ceramic-coated, stainless steel and glass-bowl models are available. Our guide Are Air Fryers Toxic? explains the difference between PFAS, PFOA and PTFE and what to look for.
For electrical safety, buy from a reputable UK retailer, check the model has a proper UK plug and instructions, register it with the manufacturer so you hear about any recalls, and never run it on carpet or under wall cupboards that trap heat.
How Much Should You Spend?
| Budget | What you typically get | Who it suits |
|---|---|---|
| £40–80 | Single basket, around 3–5L, analogue dials or basic digital controls | Singles, couples, a first air fryer |
| £80–150 | Larger single baskets and most dual-zone models, better build and easier-clean parts | Most families — the sweet spot for value |
| £150+ | Large dual-zone, oven-style and multi-cooker models with extra functions | Big households, batch cooks, people replacing other appliances |
Spending more mostly buys capacity, a second drawer and nicer build quality — not better-tasting chips. A well-sized mid-range model will cook as well as a premium one for everyday meals.
Checklist Before You Buy
- Measure your worktop, including the space needed to pull the drawer fully out and clearance above for hot air to escape.
- Check each drawer’s capacity on dual-zone models, not just the total.
- Check the basket shape. Wide, flat baskets crisp better than tall, narrow ones of the same volume.
- Look at the warranty and whether replacement baskets and crisper plates are sold separately.
- Read reviews for noise and cleaning — the two complaints that come up most once the novelty wears off.
Frequently Asked Questions
Is a dual-zone air fryer worth it?
For households of three or more, usually yes. Cooking a main and a side at different temperatures, finishing together, saves time and avoids one part of the meal going cold. For one or two people, a single basket is simpler and cheaper.
What size air fryer is best for a family of four?
Around 6–9L in total. A dual-zone model in that range lets you cook chicken in one drawer and chips in the other; a large single basket of 6L+ works if you mostly cook one-dish meals.
Are air fryers cheaper to run than an oven?
Yes, for most meals. They heat a much smaller space, preheat in a few minutes and often cook faster. At current UK prices a typical air fryer meal costs around a third of the same meal in a conventional oven.
Which air fryer brands are popular in the UK?
Ninja, Cosori, Tower, Philips, Salter and supermarket own brands are all widely sold. Rather than choosing by brand, choose by size and type first, then compare models from two or three brands at your budget.
