How to Dry Herbs at Home with Two Fans and Air Filters

Home cooks know firsthand what it takes to make delicious and amazing food for friends and family. One of the most effective ingredients to making foods as delicious as possible is herbs.

Unfortunately for some, fresh herbs are not always readily available. When they are, naturally you would want to home dry them to store and keep for as long as possible, as big-brand dried herbs are not very tasty at all. Even more unfortunate, herb dryers or dehydrators are often very expensive.

But do not fear. I will show you how to make a homemade herb dryer with items that you most likely already have around the house.


  • Two box fans
  • Food grade shelf liner
  • Scissors
  • Two air filters
  • Herbs
  • Bungee cords

Step 1: Obtain Fans

Grab yourself two box fans.

Step 2: Measure and Cut Shelf Liner

Next, get some perforated, non-slip, food-grade shelf liner and a pair of scissors. Measure and cut four pieces that will fit comfortably on top of your fan.

Two of the cut pieces should be rather large and two should be long and skinny (to cover where the large pieces can't.)

Step 3: Place First Air Filter

Obtain two air filters. Place the first one on top of one of the fans. Make sure that it is on the side that the air blows out from.

Step 4: Place Shelf Liner on Air Filter

Place two pieces of the shelf liner on top of the air filter.

Step 5: Lay Out Your Herbs

Grab whatever herbs you wish to dry (I chose cilantro for this demonstration) and place them in a single layer on top of the shelf liner. Make sure that none of the leaves overlap.

Step 6: Place Other Pieces of Shelf Liner

Place the other two cut pieces of shelf liner on top of the herbs.

Step 7: Lay Down Other Air Filter

Next, place the other air filter on top of the herbs.

Step 8: Add Other Fan

Take your other box fan, and then place it on top of the other air filter to make an odd sandwich.

Step 9: Secure with Bungee Cords

Secure your fans together with two bungee cords. Make sure that they are long enough to keep the rig together tight, but not so short that they compress things too much.

Step 10: Leave Alone

Move your new drying rig to somewhere it can be left alone that is cool and dry, such as a spare bedroom or closet. I chose my spare bathroom. Plug both fans in and turn them to medium speed.

Your drying rig is done! You're going to want your herbs to have a solid 16-24 hours to dry and be left alone, depending on how big your fans are and how many herbs you are drying.

You have the system delete what I have already typed when you ask me to log in after I've clicked on 'Post Response?' Well, rethink that, for one thing.

Now this seems way to big, expensive, cumbersome and rubegoldbergish for the purpose and the return. I'm sure the idea could be remcgyvered to work with a smaller round oscillating fan and round versions of the other things. I shall think upon it.

(And remember what I said up top.)
