The 5 Best RV Dehumidifiers: Knowing How to Select the Right One


If you are someone who loves to escape to the mountains or countryside in your recreational vehicle, then investing in the best RV dehumidifiers is one of the most important things you should do. It lets your life on the open road for several days more convenient and safer.

Note that all the time that you spend in a small space can also cause the buildup of damp and condensation. Your RV serves as your second home, so it is where you cook, sleep, and shower if you decide to go on a trip on your RV.

Those activities, however, when done in a small and somewhat restricted atmosphere can cause the accumulation of water vapor in the atmosphere. Such results in the damage of your soft furnishings. Also, it can cause your supposed-to-be cozy travel trailer to cause some sort of discomfort.

There is even a great chance that it will cut your vacation time short, especially if the poor atmosphere inside your vehicle gets too uncomfortable and unbearable. What’s worse? Excessive humidity inside your RV can lead to health problems and breathing difficulties, especially for those who are suffering from asthma or allergies.

Types and sizes of the best RV dehumidifiers

When figuring out what the best RV dehumidifiers in the market is, you have to check out the different types of it and their varying sizes. Gathering information about these factors can guide you in finding the one that suits your requirements and needs the best.

As for the types, your options actually include the refrigerant dehumidifier and the desiccant dehumidifier. The refrigerant type is preferred by many because it is also the one that’s commonly used at home. You can expect the refrigerant to perform its function by condensing moisture derived from the air.

The desiccant dehumidifier, on the other hand, is often water absorbent. This dehumidifier allows air to pass through after the rotor pushes it. It is smaller than the refrigerant and works only in those specific instances when it is necessary to take moisture out of a certain part of your RV, not the whole motorhome.

What about the sizes?

After knowing the types, it is also time to understand the different sizes of a dehumidifier. It should be noted that a few factors can contribute a lot to the unit’s overall size. When figuring out the perfect size for you, you also have to check how big your RV is.

Knowing the exact size of your RV will also help you find the perfect size of the dehumidifier for it. If you have a huge RV, then it is also important to look for a large dehumidifier as it plays a major role in boosting its efficiency, especially when getting rid of moisture from the air.

Also, take note that aside from the unit’s physical dimension, it is also important to consider the tank’s size. If you plan to install one in an RV, then a tank with a max of 30-pint capacity is already a good option. Such capacity is often enough as it already gives you quite a long time for the tank to get empty and require refilling.

The Best RV Dehumidifier Buyer’s Guide

Aside from the types and size of the dehumidifier, you also have to take into full consideration several other deciding factors – some of which are the following:

Space to dehumidify

One deciding factor when searching for the best dehumidifier for RV review is the exact amount of space that you intend to dehumidify. You need to know that as such will help you determine the specific capacity of the dehumidifier you have to buy.

The capacity is actually measured in pint, and it refers to the amount of moisture that your chosen top rated RV dehumidifier can take out of the air within a timeframe of 24 hours. You have to pick a unit, which is really designated for the space you plan to dehumidify as such ensures the best output.

Your choices often include small dehumidifiers, commercial dehumidifiers, and those that have 30-pint, 50-pint, and 70-pint capacity.

The Best RV Dehumidifiers Features

Assess all the features integrated into the unit you are eyeing to buy, too. One of the best features that a dehumidifier can have is the humidistat as it works in measuring the level of humidity all the time. Such a feature also switches it off automatically in case it reaches an optimum level.

There are also dehumidifiers equipped with laundry settings. It may not dry as fast as with an RV washer and dryer combo, but it will get the job done. By the continuous operation of this unit, you can expect the laundry setting to help you in drying your clothes faster. It would also be best to choose a unit with a timer. It lets you set it to perform its function for a preset period of time (usually a few hours a day.

When assessing the features, it is also important that you know exactly what you want from your dehumidifier. Such will let you know what specific features to look for.

Ease of installation

Another thing to check is whether or not the unit is easy to install. It would be best to look for a unit, which does not require excessive amounts of time and effort for it to set it up and start working.


Also, check the portability of the unit. You need a portable model, especially if you have no plans of camping or going on a trip on your RV too frequently in a year. With the portability of the unit, you can just store it in any other place conveniently in case you no longer need to use it.


The capacity of a dehumidifier refers to the specific amount of water it can hold. If you plan to take camping trips for just a week, then a large capacity is not an ideal option. However, if your trips often take longer than just a week, then go for one with a really large capacity, something that is capable of holding more water.


Another crucial factor that can greatly affect your buying decision is the noise level of the dehumidifier. Check the amount of noise that it can produce once it starts functioning. You can assess the noise level of the unit by checking the technical specification expressed in decibel (dB).

If it has a higher than usual dB, then it also means that it produces a loud sound. You need to go for one with minimal operating noise so it won’t disrupt you especially once you fall asleep in your vehicle. If possible, go for any of those that feature innovative technologies that promote a whisper-quiet operation.


If your choice has digital controls, then make sure that such controls are really user-friendly. If possible, the controls should let you set a certain humidity level based on category (ex. very dry or just dry). You should also be able to set it based on percentage.

You need user-friendly controls as it will give you more than enough power to make an adjustment to the operations. With that, you can address all the things that the unit is supposed to address, including major humidity challenges, such as a flood. It should also be able to handle just moderate preference in lifestyle, like slightly lower humidity.
