Experienced travelers know their RV serves as a home away from home, which is why they take care of it as they would a house.
Unfortunately, an RV or travel trailer has limited ventilation, so activities such as bathing, cooking, and doing the laundry cause moisture in the room to soar, and the air quality to plummet. This results in increased moisture in the stale air of your RV, making the damp air an ideal breeding ground for mold, mildew, and all sorts of bacteria.

The Best RV Dehumidifier
1. Honeywell TP70WK
First up in our reviews today, the TP70WK Humidifier unit from a brand renowned for its top-quality products and design. Control the humidity in medium to large rooms up to 4,000 sq feet.
the TP70WK features Energy Star certification, which means that this dehumidifier is not only powerful, but it also uses less electricity than a conventional dehumidifier, saving you more money in the long run and using less energy. Taking the eco-friendliness a step further, the TP70WK also has a durable and easily washable filter that will age with the dehumidifier.
The best thing about buying a product from a renowned brand is that you have peace of mind in case something goes wrong with your device. In this event, you can call the Honeywell Comfort customer service hotline to help you with maintenance. When you purchase a Honeywell product, quality is guaranteed.
The Smart Digital Humidistat control on this energy efficient device automatically activates the appliance based on your preferred pre-set humidity levels. An additional feature is the 24-hour energy-saving timer, a sleep mode, low-temperature operation, auto-defrost, and auto-restart function after a power outage. These make the TP70WK one of the best dehumidifiers for mold out there. It also features a drainage outlet and a hose included, something that most companies don’t include in their package, saving you the time and trouble of having to go out and purchase one.
This is the most expensive unit on our list, but it’s well worth the cost. You’re investing in a well-made, long-lasting product, by a well-respected, long-standing brand. If that isn’t enough to convince you, Honeywell also has great reviews on the extended warranty of their products.

3. Eva-Dry E-333 Renewable Mini-Dehumidifier
You can cut down on excess moisture without increasing your carbon footprint with the Eva-Dry E33. This unit features renewable silica gel beads. The beads capture airborne liquid for up to eight weeks, and when it’s full, you can simply plug the unit in a ventilated area to recharge the beads.
This device is entirely silent because of its renewable gel technology, unlike other units that require batteries or electricity. In terms of the size, the E-333 gives you the advantage of fitting into little spaces that other types of dehumidifiers can’t. In terms of ease of use, it is extremely easy to operate because it doesn’t require batteries or electricity. There isn’t even a water tank to empty on these units.
This wireless and tiny dehumidifier unit is the size of a car radio, making it very portable. This unit works through the process of absorption. The gel inside the unit absorbs and attracts moisture through the unit’s plastic front grill. The gel changes color from blue to pink when saturated. You can plug the unit to “recharge” it, and the heat from the electrical unit dries out the gel so that you can use it again.
The portable unit has a moisture removal capacity of 4 to 6 ounces. According to the manufacturer, the E-333 will reach its capacity after 2-4 weeks of use, depending on the conditions of the space the unit is dehumidifying. It reaches its capacity more quickly in more humid and warmer conditions.
The design of this device works best for humidity control in mild humidity conditions in small spaces—like a gun safe. At approximately $20, the E-333 is a very inexpensive solution to mild humidity problems.
