The Cosori Premium is the dehydrator we'd recommend to most people. A rear fan dries every tray evenly, the stainless trays clean up easily, and in TechGearLab's test it never strayed more than three degrees from its setting. The trade-off is capacity: six trays fill up fast during harvest season.

How it dries
A rear-mounted fan pushes warm air across six stainless steel trays, so there's no need to rotate them. Temperature runs from 95 to 165°F, and the timer goes to 48 hours in 30-minute steps. Cosori rates it at under 48 dB.
Test results
TechGearLab found it the most temperature-accurate model it tested, never varying more than three degrees from the set point, though it scored lower for ease of cleaning. Food Network named it best overall: every food came out even and uncracked, and fruit leather released easily from the included sheet.
In the box
Six stainless trays, a fruit roll sheet, a mesh screen and a 50-recipe book. The unit measures 13.4 × 17.8 × 12.4 in.
Price and warranty
$159.99 list; Cosori had it at $143.99 when we checked. Two-year limited warranty and a 30-day money-back guarantee.
After it's dry
Whatever you dry, cool it, condition it and pack it airtight. Our sister site covers vacuum sealing dried food and vacuum sealing mason jars.
This review is based on Cosori's published specifications and independent test results (we name whose test each figure comes from), compared against the other dehydrators we track. We'll add hands-on notes as our own testing progresses.
Questions
Do you need to rotate the trays?
No. The rear fan blows air across all six trays at once.
Is the Cosori good for jerky?
Yes. It reaches 165°F. Heat the meat to 160°F first, as USDA advises; see how to make jerky safely.
