Besides feeling great on a hot summer day, fans are best at circulating air. That’s exactly what they do in your humidor too. By gently circulating the air in your humidor, an even distribution of humidity is dispersed at all times. This means the few cigars you forgot about on the bottom, are as good to go as your favorites on top. Just make sure you have a unit compatible with a fan kit. Otherwise it’s as useful as a….errr fan with no cord.
