Best RV Dehumidifier Guide

RV life is an example of small living, where we take a shower, cook and sleep. All these activities in such a small space can cause the buildup of vapor and water condensation in the air. And that is why you will need the best RV dehumidifier in your RV.

What is a dehumidifier and how does it work?

RV dehumidifier is a unique device that dehumidify the air in your RV making it clean and safe for breathing. It is portable and light in weight than residential dehumidifiers. They usually run on electric.

Moisture collects in the tank and you have to empty it when full. It functions by getting rid of moisture from the air, which would have led to the growth of mildew, mold and rust in the RV. It also aids in removing dampness, which can lead to build up of infectious organisms like bacteria in your RV.

An RV dehumidifier is a good appliance to invest in because it improves the air in your RV and makes it fresh and safe for your family to breathe.

The different types of RV dehumidifiers available

There are two different types of dehumidifies:

  • Desiccant Dehumidifier
  • Refrigerant Dehumidifier

The refrigerant dehumidifier is what you will find in homes and is a popular choice for RV owners. It works using the condensation process, by condensing the humid air found in your RV.

The second RV dehumidifier is the desiccant dehumidifier, which absorbs water and allows air to pass through it. The desiccant is small compared to the refrigerant. Those who want to get rid of moisture from a specific part of the RV (eg. bedroom) and not the whole of it will prefer a desiccant dehumidifier.

There are many different models to choose from if you are in the market for a dehumidifier. As such you will find yourself overwhelmed with options. That is why it is important for you to know the different factors to consider when you are looking to buy an RV dehumidifier.

Size and Space

Before shopping for your dehumidifier, you might want to consider the size of the space you want it to dehumidify. You should already know where you want the appliance to be in your RV. Figure out the size of the appliance that you would want to buy.

If you need your dehumidifier to be portable so that you can move it around, then you should take note of that and have that as one of your consideration when shopping around.

Ease of Installation

When shopping for your RV dehumidifier, find one that will make it easy for you to install. You would not want to get a dehumidifier that will take a lot of your time setting up. Or worst, one that require lots of steps and tools to setup with manuals written in a language that you do not know.

Noise level

You should find a dehumidifier that will not irritate you due to its noise. One way to know its noise level is look at the decibel level found on its label. If its decibel is high means it produces a lot of noise, opt for one with a minimal decibel rating. You can also buy the ones that have a better technology; they operate without any noise.

Capacity of Dehumidifier

It is important to consider the capacity of the appliance you are choosing. It means the amount of moisture the humidifier can accumulate. If you want to use it for a shorter period, you choose one with a lesser capacity. If you are doing fulltime RVing then you should opt for a dehumidifier that offers a bigger capacity and is able to retain more moisture.

When looking at what capacity, check for pint capacity. This is how much moisture the appliance can clear from the air in a day. You have to consider one that will be efficient and deliver top performance. You have the option of choosing small which has a smaller capacity or the commercial ones with capacity range from 30 pint to 70 pint.


Simple and easy to operate should be other factor to consider when choosing a dehumidifier for your RV. You should opt for user-friendly models even if you are buying digitally controlled ones.

Another thing, you should check if the appliance you choose offers an option to adjust the humidity levels according to your preference. Some offer dry or extremely dry levels of humidity. You should make your choice based on your preferred humidity percentage.


It is important to look at the different functions each model offers. You might want to opt for one that is equipped with a humidistat for measuring humidity levels, which also works automatically, whereby it goes off when the air is free from humidity.

There are dehumidifiers that come with laundry settings, which you may use for drying laundry faster when operating continuously. When checking out for features, you should find one that will best suit your needs and lifestyle.
