From generators to water filters, your RV will really need these tools for it to become a conducive residence.

But things just don't stop there. You also need to mind the temperature of your motorhome as well. If it is cold, then you should have a standby electric heater. If things get humid, a dehumidifier is certainly needed.

Sure. Some of you would say that you can deal with humid and warm temperatures. However, let me remind you that there are a variety of inconveniences that only thrives in dry climates. Allergies, molds, and dust mites are among these.

If you let your RV stay humid, you and your family are susceptible from experiencing these unwanted manifestations. Of course, they would lead to illnesses and inconveniences such as irritation, rashes, and itching.

How To Choose The Best Dehumidifier For RV

You are already aware of the importance of a dehumidifier and when you should get one. This time, it is already appropriate to highlight the guidelines on choosing this item.

Always keep in your mind that dehumidifiers for RVs today have different and unique specifications. Therefore, it is crucial that you can get the right one that fits your setup.

Size Of The Dehumidifier

One of the most crucial aspects of choosing a dehumidifier is its size. It is noted that the size of the dehumidifier is determinant to its performance. Specifically, the total capacity of the dehumidifier to extinguish humidity and moisture is rated by its size.

The size here is not really related to the physical dimensions of a dehumidifier. But somehow, it still works that way. For instance, if you can see a dehumidifier that has a capacity of 50-pint, then the said device is capable of removing up to 50 pints of moisture in a day.

But of course, this is just but one factor. The size and capacity of a dehumidifier are also loosely dependent on the space that you are going to work with. It is still imperative that you know the overall space that you need to dehumidify. In fact, sizing your RV should come first before you start choosing a dehumidifier.

Overall Condition Of Your RV

It is not enough that you only know the size of the dehumidifier that you need. To get the best dehumidifier for your RV, you should also be aware of the condition of your living spaces.

You should be aware of the dampness of the rooms of your motorhome. If it is not that damp, you can just settle with low-capacity dehumidifiers. If the condition is excessive, you will need a workhorse.

Getting two or more dehumidifier is great if your space is particularly large or if it is notably wet there already.

Sizing Chart

You can refer to this guide below so that you can easily find the right dehumidifier for your RV.


Space Square Footage

300 square feet - 30 pint

500 square feet - 40 to 45 pint

700 square feet - 50 pint

1000 square feet - 60 pint

1500 square feet - 70 pint

500 square feet - 50 to 60 pint

700 square feet - 60 to 70 pint

1000 square feet - 70 pint

1500 square feet - 90 pint or more

This guide is just a basic chart that various dehumidifier manufacturers use. But if you are dealing with an extremely challenging condition, find a dehumidifier that has been tested under the Association of Home Appliance Manufacturers (AHAM).

In a standard AHAM test, they always assess the performance of a dehumidifier in conditions where the humidity reaches 60%. Units that can remove 50 pints of moisture on saturated conditions have lesser performance compared to units that can remove 50 pints of moisture under the conditions set by AHAM.


To prevent excessive moisture from developing in your RV, a dehumidifier is extremely necessary. It is the only device that can negate the effects of extreme humidity, especially if you are driving on tropical climates and terrains.

Getting the best dehumidifier for RV is a great investment. It will allow you to survive in unfavorable conditions. It can also stop the growth of molds and manifestation of unwanted odor inside your motorhome.
