For one-person batches of vegetable crisps, start with a compact single-basket air fryer, but judge it by the space available for sliced vegetables and where the appliance will be stored, not litres alone. A larger model with a dehydrate function makes more sense if you also want to dry other snacks and have room for it. Drying the slices and leaving space for airflow still matter whichever size you choose.
If you mainly prepare a small portion of vegetable crisps, a compact single-basket model is a sensible starting point. Tefal UK describes its Easy Fry Compact EY301840 as a 0.4kg, two-portion appliance for small kitchens and households; that positioning does not tell you how many slices will fit in one layer.
If worktop or cupboard space is tight, compare external dimensions as well as basket capacity. Instant Pot UK specifies its 2L Vortex Mini at 28.6 cm deep, 22.9 cm wide and 29.8 cm high.
If you also want to dry sliced fruit or vegetables, check for a dehydrate function on the exact model. The Joybuy listing for the Ninja AF100UK identifies Dehydrate alongside Air Fry, Roast and Reheat; that model is distinct from the Ninja products shown below.
Start with the space your usual slices need in the basket, then consider where the appliance will live and how you will clean its removable parts.
| Concern | What to check | Who this matters to |
|---|---|---|
| Space for crisping | Look at the usable basket base, not just capacity in litres. Check that time and temperature can be adjusted for the recipe you intend to use. | If I want crisp slices without repeatedly cooking tiny batches, I need enough room to spread my usual portion rather than pile it up. Around 42% of consumers would put room for even crisping first. |
| Worktop and storage space | Compare the appliance’s external dimensions with the space available at home, then check whether the basket suits a one-person portion. | In a small kitchen, I want to put the air fryer away without giving up more space than my snacks justify. Keeping the appliance compact would come first for around 33% of consumers. |
| Cleaning and other snacks | Check which removable parts are washable and whether the exact model offers a dehydrate function if you want one. | After making seasoned slices, I want straightforward clean-up; I may also use the appliance for other snacks. Around 25% of consumers would make cleaning or wider snack use their primary concern. |
A capacity figure does not show the shape of the usable basket base. A larger appliance can also take up more of the space you hoped to save.
Compare external dimensions and inspect the basket in product photographs or the manual. Aim for room to spread your usual portion of slices without choosing more appliance than you can conveniently store.
Preparation and loading affect the result. Tefal UK’s guidance on crisp chips highlights drying ingredients and cut thickness, but it does not establish one method or cooking time for every vegetable.
Dry slices thoroughly, avoid crowding the basket and start with a small batch. Follow the chosen model’s instructions when adjusting cooking time for different vegetables and slice thicknesses.
Cheshire Fire and Rescue Service warns that baking paper or foil can block airflow and increase fire risk.
Avoid loose paper or foil. If the manufacturer permits an accessory, follow its instructions and keep the accessory clear of the heating element.
In a May 2023 report, the Office for Product Safety and Standards identified a high fire risk involving the fuse of a specific 8L air fryer, model S-18. That finding concerns that model, not air fryers generally.
Check the exact model and seller, and look for any applicable UK product-safety alert or recall before buying.

Instant Pot UK documents a 2L Vortex Mini for shoppers considering a particularly small appliance.
The 3.8L Ninja AF100UK is a reference point if a dehydrate function matters alongside air frying.
Philips UK lists the HD9252 compact model at 4.1L, an option to compare if you want more capacity than an ultra-compact appliance.
These air fryers are relevant to making smaller vegetable-crisp batches, with different capacities and formats. Check the usable cooking area and storage fit for your own portion before choosing between them.

Consider this model if you cook for one but also want to explore drying other snacks. Check that its usable basket base accommodates your sliced portion and that its external dimensions fit your storage space. Consult the AF140UK instructions for the settings and cleaning method you need.

Consider this format if removable containers appeal for preparing and serving smaller snacks. The product name specifies 1700W, two removable glass containers with lids, and Air Fry, Roast, Keep Warm and Recrisp functions. Check the usable base of the container you would use for slices, the appliance’s dimensions and the cleaning instructions.
Start with compact single-basket models, then check how much of your usual portion fits across the usable basket base. Instant Pot UK documents a 2L Vortex Mini, while the researched Ninja AF100UK and Philips HD9252 are listed at 3.8L and 4.1L respectively; the larger capacities may suit other cooking plans, but litres alone do not tell you how many slices fit in one layer.
Dry the slices and leave space for air to circulate, then adjust cooking to the vegetable and slice thickness. Tefal UK links drying and thinner cuts with crispness in its chip guidance; use your chosen appliance’s instructions and try a small batch rather than assuming one setting works for every vegetable.
Cheshire Fire and Rescue Service advises against using an extension lead with an air fryer and warns that baking paper or foil can block airflow and increase fire risk. Follow your appliance manufacturer’s instructions for any permitted accessory, ensuring it cannot reach the heating element.
Check the exact model and seller, keep the product instructions and look for any applicable UK safety alert or recall. The Office for Product Safety and Standards reported a high fire risk involving the fuse of a specific 8L air fryer, model S-18, in May 2023; that model-specific report does not establish a risk for every air fryer.
