But, if you notice your humidor does not hold up to 70% humidity, it is possible you have a leak in your humidor. In a recent survey conducted, it was noticed that glass top cigar humidors have the highest rate of losing humidity caused by a leaking humidor, and this happens mainly if there is a change in the weather condition.

Regardless if you have a new humidor or not, there are two methods to help you easily locate the source of the leak, and they are the dollar bill test and flashlight test method.

Dollar bill test

The dollar bill test method is highly recommended for desktop humidors because it is easier to use than the travel humidor. Below is a breakdown of the steps you will need to follow to enable you to carry out the dollar bill test easily on your humidor.

Get a dollar note and make sure it is very flat

Place half of the dollar note inside the humidor and close it, with you holding the other half outside with your hands.

Drag the dollar bill slowly out from the other half, which you are holding with your hand.

If you easily get the dollar bill out, there is a huge possibility you have a bad seal.

You should also repeat this procedure on every side of the humidor to ensure there is even distribution.

Normally, the dollar bill should not be difficult to pull out, but this test is to determine if there is a problem with the lid. If the dollar bill comes out easily, then the air can also easily escape.

Flashlight test

The flashlight test can also be done after the dollar bill test to help you have more accuracy of your humidor leakage and where the leak is coming from. Below are the procedures you need to follow to help you carry out this experiment.

Get a flashlight or a mobile device that has one.

You have to dim the lights of the room where you are

You will have to start moving the flashlight around the humidor from top to bottom.

If you notice any light passing through the humidor to the other side, then it means there is a leak in your humidor, and that is the source.

Fixing the leak

After locating the leak in your humidor, then comes a very important question, is it easier to fix the leak or to get a new humidor. Once you decide fixing your humidor is easier and cheaper, you will need to apply food-grade silicone on the cracks. There are different methods available, but this is the best, and it will only take a few days to cure. Below are the procedures to follow if you want to fix your humidor leak.

Get a non-toxic silicone that is also odorless

In the tupperdor or Ziploc bag, place the cigars inside for temporary storage

You will have to seal the leak on your humidor from the interior because it might not be effective and might spoil the look of your humidor

Allow the silicone to dry on your humidor, and you might need to wait for about three days.

Then you will have to put back the hygrometer and humidification for at least 24 hours or until the humidity level reaches 70%
