Quick answer: Compare the usable basket or tray dimensions, not litres alone. Match the appliance to the foods and batch sizes you actually cook, then check external dimensions, ventilation clearance, controls, cleaning, power input and whether included accessories are useful.
Independent testing by CHOICE warns that claimed air-fryer capacity can be confusing because brands may describe total cavity volume rather than practical cooking capacity. A wide single layer can be more useful than a deeper basket with the same litre claim.
Define the normal cooking load
Write down three meals you expect to cook most often and the number of portions. Then compare whether the basket can hold that food in the arrangement required by the instructions. Crowding or stacking can reduce browning and increase cooking time.
- For chips or vegetables, compare basket base area and the recommended maximum quantity.
- For chicken, fish or schnitzels, check the longest and widest usable dimensions.
- For a whole chicken, verify the stated food size and required clearance around it.
- For dual-zone cooking, compare each basket separately, not only the combined litre figure.
Choose the format
| Format | Useful when | Trade-offs to check |
|---|---|---|
| Single drawer | One main food or simple batches | Basket area, depth, shake access and total batch count |
| Dual drawer | Two foods need different time or temperature | Each drawer may be narrower; combined power and bench width can be high |
| Oven style | Racks, rotisserie or broader multi-function use matter | Larger footprint, more surfaces to clean and uneven results between rack positions |
| Multi-cooker with air-fry function | Pressure, slow-cook or grill functions would genuinely be used | Weight, storage, lid handling and compromises between functions |
Measure the bench and ventilation area
Record width, depth and height with drawers and doors fully open. Check the product manual for the exact clearance from walls, overhead cupboards and other appliances. Do not apply a universal 10 cm rule. Hot exhaust can damage surfaces or recirculate into the intake when clearances are wrong.
Choose a stable, heat-resistant location where the cord reaches the wall outlet without crossing a sink, cooktop or walkway. Do not store or operate the unit beneath combustible items unless the instructions permit the complete setup.
Power and electrical use
Check the rated input on the product specification and the condition and location of the outlet. High-power kitchen appliances should not be combined carelessly on overloaded power boards. Follow the electrical instructions and stop using a damaged plug or cord.
An air fryer can use less energy than a full-sized oven for some small, short cooking jobs, but not every model or meal. CHOICE testing notes that performance and energy results vary by appliance, food load and cooking time. Compare the actual job rather than assuming one technology always wins.
Features worth comparing
- Controls: clear temperature and time adjustment, readable display and useful increments.
- Sync or match functions: valuable only when you regularly use both drawers.
- Viewing window: can reduce unnecessary opening if visibility remains clear during cooking.
- Cleaning: removable parts, accessible heating area and dishwasher suitability confirmed by the manual.
- Instructions and recipes: clear load limits, preheating and cleaning guidance.
- Replacement parts: baskets, trays and seals available for the model.
- Noise and alerts: important in open-plan homes.
Coatings and utensils
Follow the manufacturer’s instructions for the basket coating, dishwasher use and acceptable utensils. Avoid abrasive cleaners or metal tools unless explicitly allowed. Replace peeling, damaged or distorted components rather than continuing to cook with them.
Buying checklist
- List normal meals and portions.
- Compare usable basket or tray dimensions.
- Measure the complete operating footprint.
- Check manual-specific ventilation clearance.
- Review rated input and outlet location.
- Compare cleaning access and replacement parts.
- Confirm which accessories are included.
- Read warranty and return terms before use.

Frequently asked questions
What litre size air fryer suits a family?
Litres alone cannot answer this reliably. Compare the usable cooking area and whether the normal family meal fits in the required arrangement without repeated batches.
Is a dual-zone air fryer worth it?
It can be when two foods need different settings, but compare each basket’s usable size and the appliance’s total width and power.
How much clearance does an air fryer need?
Use the exact clearances in that model’s instructions. Exhaust direction and cabinet conditions vary.
Does an air fryer always use less energy than an oven?
No. It often has an advantage for smaller loads and shorter cooking, but results depend on both appliances, preheating, load and time.
Can removable parts go in the dishwasher?
Only when the manual says they are dishwasher-safe. Repeated dishwasher use may also affect some finishes, so follow the care guidance.
