This renewable mini dehumidifier is a super-compact unit, which despite its small size dehumidifies small to large gun safes like a champ. The unit is no bigger than a car radio, hence easily portable.

Power and Dehumidification Capacity

It’s hard to compete with the Eva-dry E-333 Renewable Mini Dehumidifier when it comes to moisture extraction from confined spaces, which is achieved through specially engineered crystallized silica gel.

• The silica gel adsorbs moisture through the device’s plastic front grill, and its operation is completely quiet and safe as no toxic substances are involved.
• Once the crystals reach their maximum moisture absorbing capacity, they simply change color, and there are no spills or leakages.
• This dehumidifier is capable of absorbing 4-6 ounces of moisture from your gun safe; depending on the humidity levels in your region, it should take the silica gels 2-4 weeks to fill up.
• Once the silica gels reach capacity, they will change color from orange to green.
• Monitoring the color change is super easy through a small indicator window.
• Once their color changes to green, you may renew their adsorption power by recharging the device, which is accomplished by plugging it into a wall outlet.
• This will allow the desiccant to heat up and hence liberating the moisture from it.

Setup and Usability

Using the Eva-dry E-333 Renewable Mini Dehumidifier is incredibly easy; just hang the unit in your gun safe and leave it to absorb moisture.

• With this unit, there are no batteries to contend with or cables to the plugin as it works perfectly without power.
• Also, this unit doesn’t contain a tank, and hence you don’t have to worry about carrying a heavy reservoir around and emptying it.
• It also features an innovative recharge indicator; when the crystals turn green, it’s time to renew the silica gel.
• Simply plug the device in before retiring to bed and take it out in the morning.

Cleaning and Maintenance

Maintaining the Eva-dry E-333 Renewable Mini Dehumidifier is as easy as recharging it; you’re not required to renew or replace anything.

Since the recharge process involves liberating moisture from the silica gel, it’s advisable to recharge the unit in a well-ventilated indoor space like a garage or utility room.

If your gun safe is not dry, its entire purpose of protecting your firearms is negated. Luckily, a compact dehumidifier like the ones we reviewed above will go a long way in reducing the moisture levels in the safe to avert the risk of corrosion and rot.
