Keep Your RV’s Humidity Under Control with One of the Best Dehumidifiers
These dehumidifiers will help you manage moisture and humidity inside your RV.
Think about the living conditions in your RV. You shower, sleep, eat, cook, shower, and engage in many other activities inside. Because it’s a small, confined space, there’s bound to be a lot of humidity in the air. Cracking a window may make it less stuffy, but that’s hard to do when it’s raining or freezing outside. A dehumidifier can suck up all the water vapor from your RV and make it more comfortable. Here’s a rundown of some of the best RV dehumidifiers on the market.
Your RV makes it easy to enjoy the great outdoors with all the comforts of home. Unfortunately, it also makes it pretty easy to bring all of the frustrations of home along with you, including common household issues like humidity, mold, and the damage these wet weather side effects can introduce. An RV’s interior can get surprisingly humid, just like your home, and that can leave you with unexpected repairs over the long term. But if you can keep that humidity at low levels, you can keep your camper in great shape. And the best way to do this is with a portable dehumidifier for RVs. Available in many different sizes, shapes, and forms, I’ve rounded up the best RV dehumidifiers you can employ while you camp or park your RV.

An RV needs a dehumidifier that can operate in the background without taking up valuable space. All of my picks are compact and road-ready, suitable for the power systems of RVs of varying sizes and made to sit out of the way. Plus, these devices can effectively tackle humidity, pulling significant amounts out of the air and keeping your camper’s interior feeling comfortable (and free of all of the damage-causing moisture that may linger). To assess this, I considered user reviews and the pros and cons mentioned for each machine.

What to Consider When Buying a Dehumidifier for an RV
An RV dehumidifier might not seem like an essential camper accessory, but when moisture begins to build inside, it can wreak havoc. That’s why you’ll want to keep these key details in mind as you weigh the pros and cons of different dehumidifiers.
Types of Dehumidifiers for RVs
Desiccant models are rechargeable and are ideal for enclosed spaces such as closets. They help reduce mold problems. They typically have low noise levels, a lightweight profile, and work just as efficiently when temperatures drop below 33 degrees Fahrenheit. They also keep the RV warm by blowing out warm air. However, you may need more than one desiccant model to solve the humidity problem in your RV, and they are expensive.
Refrigerant or compressor units are cheaper than desiccant models, have lower power consumption, and have a high extraction rate. You only need one refrigerant model to keep your entire RV humidity- and mold-free. However, they aren’t efficient when temperatures drop below 40 degrees Fahrenheit and are noisier than desiccant models.
Dehumidifier for RV Key Features
The capacity of a humidifier or its ability to remove water in a given range is measured in “pints of moisture.” A unit with a 30-pint extraction rate can remove moisture within a range of 300 square feet. A 50-pint dehumidifier has an operating range of about 700 square feet, and a 70-pint dehumidifier has a high operating range of up to 1,500 square feet.
Do you plan to have the dehumidifier as a permanent accessory in your RV or would you prefer to move it into your house and back? A unit under 20 pounds with wheels and a handle is easy to carry around from your basement to the RV. However, portability isn’t an issue if you want the dehumidifier in your RV all year long.
Humidistat & Timer
A humidistat regularly measures the level of humidity in the RV and automatically shuts off the dehumidifier when the air attains an optimal water vapor level. A timer comes in handy when you are away. You could set the unit to extract the vapor at a predetermined amount of time to reduce power consumption but keep the air humidity free.
Dehumidifiers for RVs Pricing
Most dehumidifiers will cost less than $50, and the options within this price range are small and ideal for small travel trailers and enclosed spaces such as closets. However, they may not come with extra features like wheels or handles for transportation, and they have a low extraction capacity. If you spend over $50 on an RV dehumidifier, you can get a larger dehumidifier with an extraction capacity than can cover a large RV. Anything smaller isn’t worth purchasing unless it’s energy-efficient and you don’t mind buying two.
You’ve got questions. The Drive has answers.
Q: What humidity level should an RV be at?
A: Aim to keep your RV’s interior humidity level between 30 and 50 percent. This is a level at which you’ll be able to keep moisture-related damage (like mold) at bay.
Q: Should you run your RV’s dehumidifier all the time?
A: When you’re camping, you can run your dehumidifier all the time. It’s generally a good idea, if you aren’t trying to conserve power, to run it for at least 12 hours during the day to keep overall humidity levels down throughout the duration of your trip.
Q: Can you use a dehumidifier when your RV is in storage?
A: If you live somewhere that’s prone to damp or humid weather and don’t plan to break your RV out often, you don’t need to plug into power and keep a dehumidifier running. Instead, you’ll want to use a product that you can use for passive dehumidifying, like DampRid. Powders or moisture-absorbing filters are a great way to soak up excess moisture in the air while you aren’t using your camper.
