An air fryer is a kitchen appliance that cooks food using a circulating stream of hot air. A heating element generates the required temperature, while a fan moves the hot air around the food at high speed. This process, known as convection, allows for cooking and browning food with a minimal amount of oil, offering a low-fat alternative to traditional deep-frying. These appliances are characterised by short preheating times and versatile applications that extend far beyond just frying.
Buyer's Guide: What to Look for When Choosing an Air Fryer
Selecting the right model depends on objective parameters based on your household size, cooking habits, and available kitchen space.
1. Capacity and Appliance Size
The usable volume of the cooking basket, measured in litres (L), is a crucial criterion. It determines the amount of food that can be prepared in a single batch.
- Small Air Fryers (up to 3 litres): These compact models are suitable for individuals or two-person households. They have a small footprint and are sufficient for preparing one to two servings.
- Medium Size (3 to 5 litres): A common size for couples or small families of up to three people. They offer a balance between footprint and capacity.
- XXL Air Fryers (over 5 litres): Designed for families of four or more, or for preparing large quantities for guests. These appliances can also accommodate whole chickens or larger cuts of meat.
2. Power and Energy Efficiency
The power of an air fryer is measured in watts (W) and typically ranges from 1000 W to 2200 W. A higher wattage generally results in shorter preheating and cooking times. Compared to a conventional oven, which has to heat a much larger cavity, an air fryer enables energy-efficient cooking. The smaller space to be heated and the often shorter cooking times lead to potentially lower electricity consumption per use.
3. Range of Functions
Modern appliances offer more than just the basic air frying function. Additional features significantly expand their range of applications.
- Air Fryer with Grill Function: Models with this feature often include a special grill plate and programmes that use higher temperatures to create roasted flavours and grill marks.
- Dual-Zone Air Fryer: These appliances have two separate cooking baskets that can be controlled independently in terms of temperature and time. This allows for the simultaneous preparation of two different components of a meal, such as fries and vegetables.
- Automatic Programmes: Preset programmes for common foods like fries, chicken, fish, or vegetables simplify operation, as the temperature and cooking time are already optimally configured.
4. Material and Cleaning
Ease of cleaning is an important factor for daily use. Most cooking baskets and inserts feature a non-stick coating (often PTFE- or ceramic-based) to prevent food from sticking. Check the manufacturer's specifications to see if the removable parts are dishwasher-safe, which further reduces cleaning effort.

Frequently Asked Questions (FAQ)
1. How does an oil-free fryer work? An oil-free fryer uses the principle of convection. A heating element heats the air to temperatures of up to 200°C. A powerful fan ensures this hot air circulates quickly and evenly around the food. This intense airflow cooks the food and creates a crispy outer layer, similar to the results of traditional deep-frying, but with significantly less or no added oil.
2. Is an air fryer more energy-efficient than an oven? In many cases, yes. An air fryer has a much smaller cooking cavity than a standard oven. This allows it to preheat faster and require less energy to maintain its operating temperature. Additionally, cooking times for many dishes are shorter. Especially when preparing small to medium-sized portions, energy consumption can be significantly lower, which supports energy-efficient cooking.
3. What can you cook in an air fryer? The applications are diverse and go far beyond just fries. You can cook chicken pieces, fish fillets, vegetable sticks, or meatballs. You can also bake rolls, reheat leftovers from the previous day, or even bake small cakes and muffins. Models with a grill function are also suitable for steaks or grilled vegetables.
