Find this model on Amazon Explore this product ↗How we chose these air fryers
We checked the exact model descriptions and published specifications, compared each choice’s practical role and reviewed relevant alternatives. We retained products where a newer name alone did not justify a change.
Our recommendations are editorial judgements based on those published differences. We have not measured performance, comfort or long-term durability. A manufacturer listing confirms a reference model, not current Amazon stock.

How to choose air fryers
How big an air fryer do you need?
Start with a typical meal rather than a household-size label. Check the room for your usual pieces of food, whether you need separate cooking temperatures and whether you accept batches. Two drawers can separate foods, but splitting a total capacity also limits the space in each drawer.
Will it fit below the kitchen cupboards?
Mark the body footprint and then account for opening, loading and the manufacturer’s ventilation clearances. Double Stack’s listed body is 28 cm wide, 47 cm deep and 38.5 cm high. CRISPi needs somewhere to put its containers; those working areas are not captured by one appliance measurement.
Compare cleanup as part of the meal
List the basket or container, plates, racks and lids you would use for a normal dinner. Read which parts are dishwasher safe and how they should cool and be cleaned. We have not tested cooking evenness, cooking speed or washing effort, so programme counts are not performance scores.
Five or seven functions: compare the bundle first
Ninja also lists a seven-function CRISPi PRO AS101UK range. This guide retains the five-function AS090UKGN38 Family Set because its three included container sizes serve the glass-container use case. Compare the exact functions you will use and included containers before paying for another version.
