Air Fryer Buying Guide

An air fryer cooks crispy food with a fraction of the oil used in deep frying. It heats up fast, cooks quickly and is easy to clean, which is why it has become one of the most popular kitchen appliances. This air fryer buying guide explains what to look for so you get the right one the first time.

How does an air fryer work?

An air fryer is a compact convection oven. A heating element and a powerful fan circulate very hot air around the food, browning the outside like frying while using little or no oil. Most recipes use a spoonful of oil or none at all.

Which size do you need?

Capacity is the most important choice. Too small and you will cook in batches; too large and it wastes space and energy.

Household	Recommended capacity
1–2 people	2–3.5 litres
3–4 people	4–5.5 litres
5+ people or batch cooking	6–8 litres, or a dual-basket model

Wattage and speed

Most air fryers use between 1,200 and 2,000 watts. Higher wattage heats faster and crisps better, especially in larger models. Make sure your kitchen socket can handle the load, and avoid running it on the same extension board as a kettle or microwave.

Basket, oven or dual-basket?

Basket style: compact and quick. Best for fries, wings and small meals.
Oven style: wider with shelves, a window and sometimes a rotisserie. Good for families and baking.
Dual-basket: two separate baskets so you can cook a main and a side at the same time.

Features worth paying for

Viewing window: check food without opening the basket.
Preset programmes: one-touch settings for fries, chicken, fish and baking.
Adjustable temperature up to 200°C: needed for proper crisping.
Non-stick, dishwasher-safe basket: makes cleaning easy.
App control: handy but optional; useful for recipe ideas.

Tips for the best results

Don’t overfill the basket; leave space for air to flow.
Shake or turn food halfway through cooking.
Lightly brush or spray oil on vegetables and fresh potatoes for extra crunch.
Preheat for 3 minutes for crispier results.

Frequently asked questions

Is air-fried food healthy?

Air frying uses far less oil than deep frying, which lowers fat and calories. The overall healthiness still depends on what you cook.

Can I bake in an air fryer?

Yes. Many models bake cakes, muffins and bread in small tins. Oven-style models are best for baking.

Does an air fryer use a lot of electricity?

It uses a similar amount of power to an oven but for a much shorter time, so it usually costs less per meal than heating a full-size oven.
