One issue that RV owners are constantly having to deal with is moisture and dampness in their RV (especially in the winter months). This can lead to mold growth inside your RV which has negative effects on you and your family’s health as well as the RV itself.
This moisture comes from a variety of sources such as cooking, showering, breathing, and running a propane furnace.

What is a Dehumidifier
A dehumidifier is a small appliance that removes moisture from the air.
How Do Dehumidifiers Work
A dehumidifier works by drawing warm air into its coils which then contracts as it’s fed through refrigerated metal channels that produce condensation inside the machine. It collects the water and stores it in a holding tank.
Why you Need a Dehumidifier if You Full Time RV
RVs come with many different features that make them great homes when it comes to livability – but when temperatures drop below freezing or humid conditions occur throughout the year, moisture levels tend to rise inside of an RV which increases indoor humidity levels dramatically.
This increase in humidity is what contributes toward mold growth, making it extremely important to have a way of lowering these high humidity levels quickly before damage occurs within your RV walls. If the humidity level in your RV is above 50% you are at risk of developing these problems.

The ideal humidity in an RV is between 40 to 50%
How to Choose the Right Dehumidifier for Your Needs
There are quite a few different options when it comes to finding the best RV dehumidifier, so here are some things that should be considered when making your decision:
- Size: How much room do you have in your RV for a dehumidifier?
- Tank Capacity: A dehumidifier’s capacity is determined by its total moisture removal ability in pints.
- Auto shut off feature: Dehumidifiers with automatic settings keep your home at the perfect level without requiring much monitoring or maintenance.
- Energy efficiency: If you are going to be off-grid make sure your battery bank can handle this type of energy consumption.
- Price: the best RV dehumidifier is one that has been carefully chosen for your RV needs and preferences. But always be mindful of your budget.
- Portability: Consider if your dehumidifier will be in the RV full time or if you will need to carry it back and forth.
- Humidistat: do you prefer having the LCD Display of the humidity level in your RV?
- Noise Level: If you are looking for a quiet RV, then most of them come with whisper-quiet amenities.
The Best Moisture Absorber for RV
A large and efficient dehumidifier is necessary for removing moisture from the air in an RV. Since RVs are notorious for having high levels of humidity, you need one that collects a lot of water and gets the moisture out of the air quickly.
We used to have the Pro Breeze mini dehumidifier that I see every other blogger review as a reliable option for your RV, but it’s not powerful enough. It had a small water holding tank that was difficult to empty, there were no indicators on the humidity level in the air and simply did not do its job well enough to justify recommending it – compared to other products on the market.
With that being said, here is my comprehensive list of dehumidifiers that will work great in your RV. Most of them are on the larger side, but when you are in an RV, trust me, this is what you need if you want to prevent mold and mildew damage.
