Best Dehumidifer for Gun Safe

It is very important to keep humidity out of your gun safe. If you live in a very humid environment this is a real challenge. Hunting season in colder climates can also exposure guns to humidity. When you come back in from the winter weather the ice cold metal components become saturated with condensation.

This is the same idea of a cold beverage on a summer day. The humidity naturally in the air comes into contact with something cold and condenses. It is pretty easy to wipe this water off the outside of your hunting rifle. But what about the trigger housing and lower receiver? There are a lot of small spaces that are difficult to reach with a cloth or Q-tip.

An easy way to solve this is keeping a desiccant dehumidifier in your gun safe. While you store your guns for the night the dehumidifier will do it’s work. The extra dry air inside the safe turbocharge the evaporation process. The extra water will be removed before it can do any damage or rust metal components.

The presence of extra humidity in places such as safes, closets, bathrooms, under kitchen sinks, inside boats, in RVs and so on, can cause nightmares. This excessive humidity can be taken care of if you use the E-333 dehumidifier.

By using the “Eva-Dry Renewable E-333 Wireless Mini Dehumidifier”, you can save energy as it does not operate on either electric power or on a battery. Though it is not suitable for large areas, it is ideal for small places like bathrooms and closets where there are chances of growth of mildew and molds.

Mode of operation:

The E-333 dehumidifier does not need electric power or batteries but works on a technology that requires replaceable silica gel. The dehumidifier can quietly absorb all the moisture in an area efficiently for an area up to 333 cubic ft. The Silica gel color can be seen in a small window, to assess how much moisture that has been absorbed by crystals.

Note: The unit does not have any indicator that lights up, and only the color of the beads have to be checked regularly. Within two to four weeks, depending on the amount of moisture present, the color of the silica gel beads will change to green when they have absorbed moisture to their full capacity of 4 to 6 ounces. After this happens, the dehumidifier has to be kept in a well-ventilated location for 8 hours to 10 hours to allow the crystals to lose the moisture and revert to their orange color. They can now be used repeatedly and for up to 10 years.

Previously the color of the crystals used was blue which used to change to pink when they became wet. The model E-333 humidifier is effective for small spaces. Remember that the place beside an open window in a large room or an area outside the house is the best place for allowing the humidifier to release the moisture into the air.

No need to buy fresh beads or cleaning up after a spill!

There is no chance of water spilling out, even when the E-333 has absorbed moisture to its full capacity. It can retain all the moisture till the beads are renewed by allowing the absorbed moisture to evaporate. Thus, costly refills can be avoided and the dehumidifier with warranty coverage of 5 years can repeatedly be used for ten years.

Advantages of the E-333 dehumidifier are:
