  • Noise: 52 dB

When you want the best-rated dehumidifier for RV use, then take a closer look at what Frigidaire has to offer. This dehumidifier is available in 30, 50, and 70 pints versions, with this offer being for the 30 pints.

All the other features are the same though, beginning with the electronic controls, the easy to read display, timer, and automatic humidity control system.

This 30-pint dehumidifier comes with a 7.6-pint water collection bucket, but it also offers you an option to connect a hose for continuous drainage of the collected water.

The water bucket comes with a handle and the electronic control will alert you once the bucket is full. The dehumidifier also features three handles, one on top and two on the sides, plus caster wheels to improve its mobility.

​This offer's downside is the relatively high cost of the units and the ​52 db noise, which is also comparably noisy.

It will work in cold weather down to 41°F without issues and Frigidaire backs it with a 1-year warranty.

Pros:

  • Removes 30-70 pints of moisture per day
  • ​Features electronic controls, including a timer function
  • Energy Star certified and UL/CUL/CSA listed
  • Feature a continuous drainage option

  • Capacity: N/A
  • Area: 1,100 cu. ft
  • Noise: 51 dB
  • Dimensions:  6.5 x 5 x 8.5 inches

Here comes a great but mini-sized electric dehumidifier for RVs. It runs on only 23 watts of electricity and is just 50.9 dB loud. Please note that this is a relatively small dehumidifier, measuring just 6.5 x 5 x 8.5 inches and weighing just 1 pound.

This dehumidifier uses no compressor, but rather a thermo-electric Peltier module to do its job, resulting in its low energy consumption. It's also very easy to understand and to use, including its air filter, detachable water tank, and simple controls.

It's one of the smallest dehumidifiers for RVs and features simple controls, including an On/Off button plus LED status indicators. This dehumidifier is for areas up to 1,100 cubic feet in size, which might seem large but is really small and definitely not for use by more than 1 person.

It has a stylish design, which lets it fit easily into the most modern interiors. The water container is easy to reach from the front but it's only a half pint large.

Pros:

  • Features an auto shut-off mechanism
  • Ideal for small campers up to 1,100 cu. ft large
  • It's silent and uses little power
  • Small enough to fit on a table or workbench

Cons:

  • Only ideal for really small spaces

  • Noise: N/A
  • Dimensions: 7 x 6 x 11 inches

Here's another small and compact desiccant dehumidifier offered by Pro Breeze at a good price. It comes with everything ready to go, including a power adapter and a user manual.

This dehumidifier has a 16-ounce water tank for collecting moisture but it only works at a rate of 9 ounces or 0.56 pint per day. Yes, it's too small for a large RV but it's perfect for a small one.

Electric functions are also available and include an auto-off function once the bucket is full, plus a LED indicator to call your attention to it.

In addition to its simplicity and ease of use, this Pro Breeze dehumidifier is also beautifully made. It's the perfect choice for someone who needs a small and beautiful dehumidifier for his recreational vehicle.

Pros:

  • Lightweight, small and compact dehumidifier
  • Removes 9 ounces (0.56 pint) of moisture per day
  • ​Runs on just 20 Watts of electric power
  • Large tank holds water for nearly 2 days

  • It lacks a frost control option
  • There's no possibility for continuous draining

  • Capacity: 50 pints
  • Area: 3,000 sq. ft
  • Noise: 55 dB
  • Dimensions: 10.8 x 15.4 x 23.3 inches

This portable dehumidifier for RVs packs a lot of features that make it stand out from the rest. First off, it can remove up to 50 pints of moisture from the air per day.

It's quite an efficient machine that can easily dehumidify areas up to 3,000 sq. ft large. You get a digital control system with a display, a timer, frost control for working in cold weather, auto-restart after a power outage, and a 14-pint large water tank.

Alerts keep you notified of necessities like a full bucket and filter change, and the option to continuously drain the water is also available. Although this package does not include the draining hose, it is still one of the best dehumidifiers for RVs. 

​Another disadvantage of this dehumidifier is its relatively high operating noise of 55 decibels. It's, however, Energy Star compliant, uses 520 Watts peak, and comes with 4 casters for easy mobility.

Pros:

  • High-capacity removal of up to 50 pints per day
  • For use in spaces up to 3,000 sq. ft large
  • A continuous draining feature is available
  • It features an easy to use interface

Cons:

This thermo-electric technology uses just 25 Watts but it's also designed for smaller spaces up to 150 sq. ft. So, while it does a great job in a small RV, it's just not for large RVs.

  • Low noise and compact dehumidifier

The Best RV Humidifiers Buying Guide

The Best RV Humidifier Buying Guide

Picking out the best dehumidifier for RVs is often a confusing experience for many people. The reasons include the conflicting information produced by different manufacturers to persuade potential customers, plus the differences in their technology.

A dehumidifier is a unique technological tool and so it needs a little understanding of its processes for you to make the right choice to fit your needs.

1. Types of Dehumidifier

The first thing to understand about dehumidifiers is that there are three major types based on the process they use in removing water from the environment.

These three types are the refrigerant, the desiccant, and the Peltier dehumidifiers. Following is a closer look at them:

Refrigerant. These dehumidifier types use a compressor to create a colder surface in the environment upon which water vapor condenses to become water. The water is then channeled into the tank.

Refrigerant dehumidifiers are more energy-efficient and they're better for use in a warmer environment. They do not work well in cold temperatures under 15 °C because of the nature of the compressor.

Desiccant. With desiccant dehumidifiers, a desiccant wheel gets used in absorbing the moisture from the air. This system has no compressor, but it does use a fan and an internal heater to recharge the desiccant.

A desiccant is any material that naturally absorbs moisture from the air. Desiccant dehumidifiers are lighter, quieter in operation, and work well in cold temperatures.

Peltier/Thermo-Electric. This third type of dehumidifier is based on a physical phenomenon, which relates electricity to temperature change.

A Peltier dehumidifier uses this phenomenon to create a cool plate upon which water condenses. Peltier dehumidifiers are small and quiet but they have a low rate of moisture removal.

2. RV Space & Dehumidifier Capacity

These are two factors that work together and therefore, need considering together. The RV space refers to the size of your RV because you'll obviously need a more powerful dehumidifier for larger spaces.

The dehumidifier capacity refers to the amount of moisture that a dehumidifier can remove in any given 24-hour period. This capacity is given in pints, while the space that the dehumidifier is ideal for is given in sq. ft.

3. Power Consumption

The amount of power that a dehumidifier uses depends first on the type of dehumidifier it is, secondly on its capacity, and thirdly on its setting at the time of use.

A refrigerant dehumidifier will use less energy on average than a desiccant dehumidifier. All other conditions being equal, a 90-pint dehumidifier will use more energy than a 45-pint model.

Some dehumidifiers come with extra features that allow higher fan speeds or other energy-intensive operations. These three aspects are what you need to consider, especially if you're on a tight energy budget.

4. Noise

Desiccant thermo-electric dehumidifiers run quieter than refrigerant models and so, are the better choice in situations where noise is a concern. They will usually produce about 40 dB in their low-speed fan modes.

In higher-speed modes though, most desiccant dehumidifiers will equal their refrigerant counterparts in noise level.

5. Drainage

Most dehumidifiers come with a water bucket for draining the moisture they collect from inside your RV. These buckets come in different sizes depending on the manufacturer, and so need different lengths of time to fill up, after which the dehumidifier turns itself off.

Some designs though, come with a continuous drain option, which allows the dehumidifier to work round the clock without needing to empty any bucket. Your choice here depends on how much convenience you want.

6. Portability

You'll also need to decide how much portability you want. If you want a dehumidifier that you can easily carry around, then look for something lightweight, else, then it doesn't really matter.

7. Ease of Use

The ease of using the dehumidifier is another point to look at. You need to check out the functions it offers to see how much easier it could make your life.

Offering a laundry setting is an example because this helps you to dry your clothes faster. Other important or helpful features include a timer, adjustable louvers, and a humidistat, which automatically measures and regulates your RVs humidity levels.

Different features could be helpful to different people, so you need to figure out which features you need and which dehumidifier provides it.

Conclusion

We've reached the end of this best dehumidifier for RVs review and you've seen all the different offers out there, including those with Peltier, desiccant, and refrigerant technologies.

While the refrigerant models offer the best price to performance value, the Peltier devices offer the least noise.

The final choice though is yours alone to make because you alone know how important price, noise, convenience, and performance are to you, and which one you find the most important in this situation.
