Best Dehumidifier for RV: Top Picks and Reviews

When you travel, your RV is essentially your home away from home. It?s where you engage in your basic activities, like showering, cooking, eating, sleeping, and relaxing.

Since all of these activities are done in a confined space, water vapor is bound to accumulate in the atmosphere. This vapor then condenses into water when it cools.

When the moisture accumulates, it can cause mold. If mold and mildew start growing in your RV, it can easily spread and lead to serious health complications, especially for people with allergies or asthma.

Furthermore, it can damage your soft furnishings, wreaking lots of havoc on your RV, which can be difficult to fix.

Mold and too much water vapor in the atmosphere will transform your cozy home into an uncomfortable one. If this continues, the atmosphere becomes unbearable, forcing you to cut your special vacation time short.

Even though just opening your window would solve the issue, this solution isn?t always available, especially in winter or when it?s raining or cold outside.

Keeping humidity at bay doesn?t have to be a struggle; all these problems can be prevented by simply using an RV dehumidifier. You?ll have to spend a reasonable amount of money on the best dehumidifier for your RV to gain comfort on the road.

In this guide, we?ve covered everything you need to know to make a successful purchase.

Things to Consider When Buying an RV Dehumidifier

You need to understand some complexities and variables before you can find the best one for your RV. That’s what this section will explore at length, the key factors that will form your final decision.

Dehumidifying Space

Knowing the amount of space you need to dehumidify is by far the most critical aspect of your quest. Many RV dehumidifiers will advertise the number of cubic feet that can be filled.

As a result, you must confirm the actual cubic footage you would like to cover and match it to the corresponding model. It’s also important that you don’t have too huge a model as the bigger the model, the more resources you’re using.

Let’s assume you need to dehumidify an area of 1,200 cubic feet; there’s no reason to buy a model that has the potential to cover 3,000 cubic feet. What you’d do is waste energy and resources.

You don’t want to dehumidify too small, either. It’s not going to have the potential to do the job efficiently. In the end, you need to know the exact square footage of the region to guarantee that you get optimum output from the dehumidifier that you end up buying.

In some particular situations, this involves choosing a model that will cover 2,200 cubic feet of your RV, which would not be challenging considering the number of options available on the market. It may sound like a little thing, but it will make a massive impact on your final decision.

Refrigerant Or Dessicant

Most dehumidifiers may be divided into a part of dual groups: refrigerant or desiccant. Refrigerant models rely on the cooling coil technique that energizes all condensation in the air into a container or water reservoir.

Desiccant dehumidifiers focus on water-soaking material that frees the air from moisture without needing a power source or daily emptying. And as you would imagine, each form has some pros and cons that the RV owner might need to know before buying.

Additional Features

Features are what all consumers are searching for first in their products, and the demand for RV dehumidifiers is no different. Each design will have its collection of specific features that will cater to you or not.

With this in mind, you have to determine the appropriate features for your device to have; do you want one with a thermostat, a laundry mode, a timer, adjustable levers, or all of the above? And these aren’t the only characteristics you can find in the RV dehumidifier.

A good dehumidifier will come with at least one of the features mentioned above. All of them have valuable features that any RV owner will benefit from. For instance, a thermostat device would constantly monitor your RV’s humidity levels and turn them off when it hits optimal levels.

Therefore, giving the consumer full regulation of the environment inside their RV. On the other hand, the laundry atmosphere is great too and can be considered a luxury.

However, the extra timer is also necessary for any RV dehumidifier that lets you schedule the device to work for several hours while you’re away from home. You’re never going to come home to a RV packed with musty air again.

And overall, flexible levers are another luxury feature; furthermore, they cause the vents’ airflow to be diverted. Again, to allow the RV owner more power over the environment of their rig.

Some features you’ve also encountered in the product analysis segment include automated shut-off, anti-slip sides, and clear tanks. Now, these are only a couple of the features you might see. But whatever the features, you have to consider what you think is important for your unit to have before making your final decision.


Typically, dehumidifiers weigh a lot and are difficult to drive around in your RV. These are the models that you’re not going to like. Instead, you’re going to want a lightweight model that gives preference to being compact.

There’s going to be a moment where you need to store the dehumidifier elsewhere, and a model with a peak portability rating would make this a much better experience than one that hurts your back when you lift it.

As you’ve seen in our product review, we’ve focused our attention on units that have this provision to ensure that driving around with your dehumidifier isn’t something you’re going to dread doing.

For example, if your basement floods, you should transport your RV dehumidifier to your basement and let it do its thing. Nevertheless, if you had a heavier model, this would be troublesome because of the amount of work required to take it into your house.

In the end, it is in your interest to invest in one that is lightweight, one of the most critical facets of your RV dehumidifier. In our opinion, if the RV dehumidifier is not lightweight, it is not a decent RV dehumidifier.

Noise Level

While this will not be a challenge for any of the desiccant systems, some coolant versions can get very noisy. Therefore, whenever you are on the lookout for a refrigerant dehumidifier, look at the consumer feedback.

These reviews would show whether or not the noise level caused discomfort. If the consumer reports define the sound levels as something like “deafening,” you should stay away from buying it.

Besides, the RV is a controlled environment and anything described as ?deafening? in a restricted room could make any sane person crazy. The RV ride is meant to be calming and stress-free. Don’t let the appliance spoil what would otherwise be a beautiful experience.


Deciding which RV dehumidifier is best for you can be quite complicated. However, choosing a top-quality dehumidifier for your RV is all about knowing your expectations and needs and picking the product that not only meets them, but exceeds them.

But when you eventually find that model, keeping your RV mold-free shouldn?t be a problem. Your RV should be a place of totally clean air that will help make your trips amazingly cozy and stress-free.

So, use the information we?ve provided you and look into buying an RV dehumidifier that is the best model for your needs and preferences. After all, no one wants to travel around in an RV that is full of humid air and musty smells.

Traveling can be difficult for multiple reasons. Don?t let your quality of air be one of them.
