Some ideas to review when shopping for a food dehydrator can be made into a small rather simplistic list. Think about how much storage space your dehydrator will need. You must figure out how often you plan to use your food dehydrator, along with what type of food you'll be most likely dehydrating. If you'll be dehydrating many different types of foods quite frequently or at the same time then consider buying 2 smaller food dehydrators for about the same cost as one larger food dehydrator. The reason this is a practical idea is because different types of foods need to dehydrate for different time periods and have different drying times. For instance you would never want to dehydrate meat and fruit at the same time in your food dehydrator because the drying times are just to different.

Keep the wattage of your food dehydrator above 500 watts with a capacity of 4-12 trays. When buying a food dehydrator with more than 1000 watts of power add a few trays to the interior to keep your food from dehydrating to quickly or becoming to dry. Likewise if you have a 24 tray food dehydrator and its fully stuffed and you have 500 watts of power you may run the risk of your food not dehydrating properly. The problem then could be that the food will not dry completely which can lead to mold or bacteria growing even inside the food.

A very common mistake that many make when buying a food dehydrator is buying a cheap "no name" model. You may wonder why this matter? The reason being "testing", usually lesser known named models in food dehydrators have not been tested as well and also may not work efficiently or will simply burn out to fast. When that happens you'll have to go through the painful process of getting a refund which is more hassle than it's worth. Another common mistake many people make with a food dehydrator is spending entirely too much. If you don't need a $200 18 tray food dehydrator don't buy one. Buy a rather more affordable 500 watt 12 tray food dehydrator for $80-$100 instead and you'll have a lot more excess money to spend on buying food to put into it.

All of the above tips will help you buy a food dehydrator that is practical for what you want one for and will keep you from buying the wrong model.
