This small dehumidifier’s performance is superior to many of its competitors.

Its energy star rating means this unit is efficient and will help you save on running costs. It can run continuously if you attach your own hose. Without a hose, it will shut-off when the tank is full. However, you’ll need to supply your own drainage hose.

  • Weighs 2.87 lbs.
  • Spacewise Portable design

A larger RV needs a higher capacity dehumidifier, and the Frigidaire High Efficiency Dehumidifier is capable of handling these bigger spaces. It can remove approximately 70 pints of moisture in a day, keeping mold and mildew at bay while also eliminating bacteria from the air.

The unit comes with the ability to customize settings. Instead of letting it run for a continuous 24-hours, you can set it to your preferred schedule. For best results, you’ll want to attach a drainage tube. Otherwise, the unit will automatically shut-off and alert you when full.

The Frigidaire High Efficiency Dehumidifier runs at temperatures down to 41°F, making it ideal for cooler climates. The unit also comes with a digital humidity readout display, allowing you to compare conditions inside with those outside.

The washable filter is easy to remove, clean, and replace, and a splash guard will protect you from spills when emptying the unit.

  • Continuous operation with drainage hose
  • Ready-select electronic controls for easy use
  • Runs on standard 115V electrical outlet

5. OXA Smart Electric Mini: Best for Small RVs

Key Features

  • Compact cube design for smaller spaces 
  • Energy-efficient, drawing only 23 watts
  • Covers up to 215 ft² spaces with ease
  • Comes with a sleep mode setting
  • Sleek, attractive design

For smaller RVs,  the OXA Smart Electric Mini Dehydrator is a great choice. Measuring in at a compact 5.9” x 7.1” x 7.1” size, this cube-shaped unit will fit in anywhere. Set it in a corner, on a countertop, or anywhere else you have room.

The most unique feature is the unit’s two modes, one for normal operation and one for quieter running at nighttime. Just remember to return it back to normal in the morning so you can remove the maximum moisture from the air during the day.

While its tank capacity is small, you won’t have to empty it every day unless the humidity is excessive where you are. This compact unit also comes with a precise shut-off feature for when full, so you don’t have to be concerned with it spilling while you are out.

Ultra-efficient, this dehumidifier is perfect for smaller RVs or as an additional unit to supplement a larger one already in use.

Pros

  • Removes .7 pints of moisture per day
  • Automatic shut-off feature for when full
  • Unit won’t drain you RV onboard battery
  • Ultra-quiet when running

Cons

  • Small tank capacity which requires emptying more often
  • Not recommended for RVs larger than 27 ft.

Who Should Get This? 

Owners of smaller RVs will benefit from having at least one OXA Smart Electric Mini dehumidifier on board.

Key Features

  • No need for electrical outlet or batteries
  • Silica-gel beads are non-toxic to children and pets
  • Compact, lightweight design
  • Renewable/rechargeable for easy use
  • Indicator light tells you it’s ready for recharging

For those tiny areas in your RV, add an Ava-Dry Renewable Mini Dehumidifier to help keep moisture under control. 

These small dehumidifiers require no electric plug-in or constant emptying of a tank. Instead, they work by absorbing moisture into non-toxic silica-gel beads located inside the tiny unit. The silica gel beads absorb moisture for up to 30 days before you need to recharge them. 

In addition, the Ava-Dry Renewable Mini Dehumidifier is silent, so much so you’ll forget it is even there. Since the air will be cleaner, and no mold or mildew develops, you may even forget you have one of these hidden away. Be sure to set yourself a reminder, though, to check on your unit every month. Look for the orange light indicating it is time to recharge.

Buy a few of these mini dehumidifiers and place them wherever moisture is at a premium, such as under sinks in the bathroom and kitchen area of your RV.

Pros

  • Absorbs moisture in areas up to 333 ft³
  • Small enough to fit under sinks or in RV closets
  • Leak and spill-proof design
  • No need for expensive refills
  • One unit can last 10 years

Cons

  • Will require several units to help with humidity

  • Ultra-quiet technology
  • 1 button control for ease of use
  • Weighs 2.16 lbs.

For those who like to spend time in both warm and cool environments, the Hauture Electric Mini Dehumidifier is an excellent choice to keep moisture under control

While it runs efficiently in warmer temperatures, the Hauture Electric Mini Dehumidifier particularly excels in lower temperatures due to its unique defrosting function. It will keep working until the temperature drops to a chilly 41°F.

Removing up to 10 oz. of moisture a day and capable of holding up to 20 oz. at a time before shutting down automatically, this unit is efficient and user friendly.

Another fantastic feature is that it is ultra-quiet when running. It hums a low, consistent whisper that blends in, so you may never even notice it is there. You’ll be able to sleep, play board games, or listen to music without being disturbed.

How to Choose the Best Dehumidifiers for RV?

You know you need a dehumidifier for your RV, but how do you go about choosing the right one? A lot will depend on the actual size of your RV or space you wish to use your dehumidifier. There are other features to consider as well, so I’ve outlined a few of these below to help you choose the best for you and your family’s adventures.

Size

The size of your RV will be instrumental in the type and capacity dehumidifier you choose. While you may have a 36 ft. RV, space is still at a premium, just like those with smaller ones.

Everything needs to have a designated spot, including your new dehumidifier. Look around and measure how much space you have available. Ideally, it will fit in an out of the way space, avoiding trips and eyesores.

Space Requiring Dehumidifying

Measure the square footage of your RV, then look for a compatible dehumidifier designed for a similar space. Ones on this list range from small to large areas, so you’ll have several choices.  This is the most important factor to confirm, as you want a dehumidifier that covers the entire space you need it to.

Location

If you plan to spend long periods in high humidity locations, look for a dehumidifier with a larger capacity holding tank that pulls more moisture out of the air in 24 hours. All of these aren’t necessarily larger units. Some compact dehumidifiers are designed to work in high humidity areas as well.

Energy Usage

Your RV battery is most likely already close to its limit, so you don’t want to add much more.  A good option is a dehumidifier that allows you to set a continuous, 24-hour cycle. Otherwise, look for energy efficiency or go with a battery or rechargeable option.

Automatic Settings

If you don’t plan to install a drainage tube with your dehumidifier, then look for one that has an automatic shut-off and indicator light when full. This will prevent messy spills.

Noise Output

Hearing a noisy compressor will disturb your relaxation time, so be sure to research noise levels for each dehumidifier you are considering.

Portability

How often will you be moving your dehumidifier around? Will you store it somewhere else and only bring it in when you need it, or will it have a permanent designated space

If you plan to connect a drainage hose for continuous use, then you may need to move it back and forth at times. If so, be sure to look for a lightweight option that you can easily pick up and reposition. Many dehumidifiers today have built-in handles and wheels for ease and convenience.

Final Verdict: Our Top Choice

While there are several dehumidifiers on the market, not all are suitable for an RV. My preference is the Pro Breeze Electric Mini Dehumidifier, a practical, efficient, and all-around best unit for most size RVs. Lightweight, compact, quiet, and easy to use, this dehumidifier is by far the top choice to keep your RV moisture-free.

The Pro Breeze is also rated for the highest humidity areas, making it fantastic for keeping mold and mildew out of your RV and leaving your interior air healthy and clean. You don’t have to worry about any spills either, as the automatic shut off alerts you when the tank is full. For a reliable, all-around best performing dehumidifier for your RV, look no further than the Pro Breeze.
