Can you dehydrate in an air fryer?
Yes, for small batches of fruit and herbs. The limits are capacity and the lowest temperature the machine will hold, and both matter more than the button on the panel.

What the dehydrate setting actually changes
It drops the fan speed and lets the machine sit at a low temperature for hours instead of minutes. Nothing else. The heating element and the basket are the same ones that cook your chips.
That matters because most air fryers cannot hold a temperature below 35 to 40 C, and several start their range at 40 or 50. Herbs want 35 to 40. Anything higher drives off the oils you are drying them for.
Capacity is the real limit
An air fryer basket holds one layer. A stacking dehydrator holds five to nine. Six apples fill four dehydrator trays and take roughly eight hours in one run. The same six apples in an air fryer are four or five separate batches, each needing its own hours.
Some models sell a rack with two or three shelves. It helps, but the shelves sit close together and the fan pushes air past rather than through, so pieces on the bottom finish long before the top.
Where the air fryer wins
One tray of apple crisps or a handful of herbs, when you want them today and do not want another appliance on the counter. Also good for finishing: a batch that came out of the dehydrator slightly soft can be tightened up in fifteen minutes.
If you dry food three or four times a year, this is the honest answer. A dehydrator earns its space at weekly use, not occasional use.
Where it fails
| Food | Air fryer | Why |
|---|---|---|
| Herbs | Usually too hot | Lowest setting often 40 C or above |
| Jerky | No | Cannot hold 70 C evenly for six hours across a full load, and one layer means half a kilo at most |
| Fruit leather | No | No solid sheet, and the airflow ripples the puree |
| Garden gluts | No | One layer per cycle turns a harvest into a week of batches |
| Apple or banana slices | Yes, small batch | Works well at 55 to 60 C |
If you try it, do this
Cut thinner than you would for a dehydrator, around 3 mm, so the shorter cycle finishes the centre. Leave gaps between pieces. Check every 45 minutes, because the swing between the thermostat's on and off is wider than a dehydrator's.
Expect it to cost more per batch. The element cycles harder to hold a low temperature in a small chamber, and you are running several cycles instead of one.
Questions people ask
Is an air fryer as good as a dehydrator? For one tray, close enough. For anything you would call a batch, no.
How long does fruit take? Roughly the same as a dehydrator at the same temperature, six to nine hours for 4 mm apple, because drying is set by temperature and airflow rather than by the appliance name.
Can an air fryer make jerky? Not safely as a whole process. You can heat the meat to 71 C in the air fryer and dry it in a dehydrator, but the air fryer alone cannot hold a drying temperature for the time jerky needs.
Safety note. For meat, USDA guidance is to heat beef to 71 C or 160 F and poultry to 74 C or 165 F. An appliance that cannot document its temperature at the food surface should not be used as the only heat step for jerky.
