In the run-up to the test, we defined practical requirements and established the following test criteria:
- Frying performance
- Control panel
In order to be able to evaluate these criteria, we have defined several tests for the hot-air fryers. In these, all appliances must prepare 750 g of ribbed chips and 750 g of chicken wings. If appliances cannot absorb this amount, the maximum possible amount is used. First of all, the scope of delivery, functions and filling quantity of the appliances are checked. The first foods to be prepared are French fries in the deep fryers. Meanwhile, the required time is stopped. Then the fries are tasted and evaluated by test persons. Particular attention is paid to the crispness of the fries. The process is repeated with the chicken wings. The volume is measured in normal mode at 200 degrees without content. Finally, the appliances are cleaned and checked whether individual parts are dishwasher safe.
In order to exclude errors and to ensure that the test is not affected by everyday use, each test is carried out in several runs.
The test criteria are given percentages according to their importance. The final mark is finally calculated objectively from the test criteria using an algorithm.
Our product selection is based on the observation of the current market. In addition to popular brand products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come on the market, our test field will be expanded to include them. The new products undergo the same tests as already tested devices.
