Best RV Dehumdifier
TOP PICK: Pro Breeze 2200 Cubic ft Electric Mini Dehumidifier
The following RV dehumidifiers have been selected based on performance, efficiency, ease of use and price point.
Our testing method involves a combination of the above criteria, plus recent customer reviews and feedback on operational quality, as well as analysis of how each of the models fares against others on the market.
Our top pick RV dehumidifier for 2020 is the Pro Breeze Mini, 2200 cubic feet model.
If you have a large-sized RV this top-quality unit will be just the answer you need. Featuring a lightweight and compact design the dehumidifier is able to remove up to 18 ounces of water per day.
As the title suggests it is best used within RVs no more than 220sq ft in area size, (this translates to around 2200 cubic feet).
The real benefit of this model and one of the reasons it has been chosen as our top-rated pick is the quiet operation.
Utilizing what the manufacturers have labeled an advanced Peltier technology; the unit is both highly energy-efficient while being low in volume. Essentially, you can keep the Pro Breeze working day and night without disturbance. The low power consumption is just what you need in terms of less drain on your RV too.
The unit has a large 52-ounce capacity water tank to absorb all the water from the air. An LED indicator will flash when this is full. The Pro Breeze also has an auto-shutoff when the unit is full in case you are not there to empty it.
As with the majority of mini dehumidifiers available on the market, the Pro Breese has an optimal operating temperature. In this case, it is between 59-86F. However, you should be aware that the unit will not work below 41F.
Pros of the Pro Breeze Electric Mini Dehumidifier
Suits RVs up to 220-sq-ft
Compact and lightweight design
Large 52-ounce capacity water tank, capable of absorbing 18 ounces a day
Ultra-Quiet Peltier Technology allowing you to run the unit without disturbance
Energy-efficient with low power consumption
Auto-Off and LED indicator when full
Some complaints that the unit fails to perform to advertised levels in a 2200 cubic room.
Overall the Pro Breeze Electric Mini Dehumidifier is a great little unit that will take care of your RV dehumidifier needs.
With its quiet, low energy operation and good rate of 18 ounce absorption per day, if you have humidity issues in your large sized RV, this is the model to buy.
The second RV dehumidifier option in our top 7 has a much smaller tank at just 2 liters.
While this clearly will fill up relatively quickly, to ensure continued operation while you are not present to empty the tank, the InvisiPure also has the ability to be connected to a 3/8” hose for continuous drainage.
This hose in not included with the original unit, however.
Beyond this, a very adequate absorption rate of up to 27 ounces (800 ml / 1.7 pints) is provided by the HydroWave. This is a high level of water from the air removal and makes this a great option if you do have severe humidity issues within your RV.
[Note: The manufacturers state that this level of performance is based on approximately 86⁰ F and 80% relative humidity. If you have less humidity in the air, you can expect removal levels of around 16-27 ounces per day)
Similar to the Pro Breeze, the InvisiPure has a built-in Automatic shutoff, that activates once the tank is full.
It also uses Peltier dehumidification technology in order to remain quiet yet efficient in operation.
For peace of mind, a one year warranty & lifetime support is included with each unit.
Pros of the InvisiPure Hydrowave Dehumidifier
Takes up little space, especially when used with the tank drainage hose (not included)
High performance up to 27 ounces per day water removal (under applicable conditions)
Peltier dehumidification technology
Inbuilt Automatic shutoff should tank become full.
For a number of uses, the unit fails to live up to 27 ounces a day moisture extraction
The InvisiPure HydroWave is another great RV dehumidifier, especially if you decide to hook up the overflow pipe for continuous, uninterrupted water removal.
If you live or travel with your RV in humid climes, you really will not be disappointed.
The Afloia Electric Home Dehumidifier closely matches our number one pick in terms of square feet suitability, (here 215sq ft instead of the Pro Breezes 220), making them suitable for large RV spaces.
Water absorption rates are lower with the Afloia however, in that this unit has a day rate of just 11 ounces (300±50ml).
It will take longer to fill the tank up as a result, especially as this has a capacity of 24 ounces (700ml). (The above specifications are appropriate in 86°F, 80%RH operating conditions.)
Latest Peltier technology has once again been used in the design of the Afloia. (Most of the models in our top 7 utilize the technology in order to be efficient and ultra-quiet.) In this case, the noise comes in below 33dB; perfect for undisturbed sleep in a small family RV.
The auto-shutoff on this unit is powered through a DC adapter. This feature will obviously shut down the dehumidifier once the tank is full.
And much like all mini dehumidifiers designed for use in RVs, the design is the lightweight, portable and compact meaning you can conveniently pack it for your next RV trip without taking up much cabin space at all.
Pros of the Afloia Electric Home Dehumidifier
Small and compact
Quiet and efficient operation
Good sized tank considering absorption ability
Users have complained about extraction performance in larger spaces
Overall the Afloia Electric Home Dehumidifier is a good little unit that will get the job done. It’s affordable and lightweight which is what you need in your RV dehumidifier.
Absorption rates are lower than some of the other models in our top 7 so this should be considered too.
You’ll have to forgive us for seeming biased, however we have opted to give another model from Pro Breeze a top pick accolade.
This time it is in the form of our best budget choice RV dehumidifier.
The Pro Breeze 1200 Cubic Feet features the same design and technology as the top pick model however this model (as the name suggests) is suitable for smaller RVs.
The specifications have been reduced of course. On offer here is 1200 cubic feet capacity, along with a mere 9 ounces of water per day absorption rate (compared to the larger models 2200 cubic feet and 18 ounces per day removal).
However, the unit is significantly cheaper and one of the best budget prices in our top 7.
So, if you have a smaller RV this is basically the top pick option for you.
Pros of the Pro Breeze Electric Mini Dehumidifier
Compact, efficient and quiet operation
Specs well suited to small RVs
The very competitive price point
It only works in small rooms as the specs are low.
The same great features of our top pick, (compact design, auto shutoff efficient and quiet operation), but with reduced specifications to meet the needs of smaller RVs.
And of course, along with that you benefit with a reduced price point. A top quality unit that is a no brainer as our top budget choice for 2020.
The Hysure Dehumdifier is a model suited to small and medium RVs with a cubic feet capacity of 1200.
The unit features a 700ml tank making it both a compact option for your RV dehumidifying needs, while having a moderate storage capability.
Peltier technology is once again all present and correct and helps give the unit an increase in efficiency while being ultra-quiet to run.
300ml of moisture per day can be retrieved from the air, making this a system in line with many of the models in our top 7 review round up.
There is an auto-shutoff built-in of course, (otherwise, you could end up with an extremely wet RV if the tank overflowed. The 700ml tank will fill up in just over 2 days, meaning if you’re not there to empty it, the unit will switch off until the water is cleared.
Hysure offers a 30 days money back or exchange guarantee on the unit, which is a nice touch to increase peace of mind on the purchase.
They also back the dehumidifier with a 24 months warranty. The company also has a well-regarded customer service team that is easy to get hold of, should you experience any problems.
Prod of the Hysure Dehumidifier 1200 cubic feet
Peltier technology for quiet and efficient operation
Compact design great for RVs
Good specs with 700ml tank and 300ml daily moisture absorption
30 days money back or exchange guarantee with 24 months warranty
Minor complaints on the power of the fan
Again, a minority of reviews fault the extraction level and speed
Overall the Hysure Dehumidifier,700ml Compact is a reliable little unit. With good specs for a small to medium RV and at a competitive price point there’s a lot to like here.
Another worthy addition to our top 7 selection of RV dehumidifiers.
Our premium choice RV dehumidifier for 2020 is the Ivation 11 Pint Small-Area Compressor Dehumidifier.
With its high performance, built-in air purifier and superior smart touch operation, the unit clearly is a cut above the competition reviewed here in our top 7 round-up.
The compressor dehumidifier is designed specifically for smaller spaces, (RVs included) and is able to combat areas up to 216 sq ft with a daily absorption rate of 11 pints.
What we really liked about the model however, (and it really is a small addition that goes a long way) is the integrated air purifier.
This built-in ionizer purifies the air via negative ion technology. Not only does this clean the air, it is also deodorized so that the inside of your RV is a more comfortable, healthier environment.
There’s also Ivation’s the smart touch operation to rave about. This intuitive system of control allows you to set the humidity levels while providing a clear indication of current settings. The system then continuously monitors the air to maintain the selected level.
This smart controller also conserves energy by allowing you to set the humidity levels in 5% increments.
The easy to read display will also alert you if humidity levels dip below 20% or above 95%.
The unit also comes with a continuous drain hose so that you need not worry about emptying the tank when it becomes full.
However, as a failsafe, there is also an auto defrost/auto-shutoff system in place. This will continue the unit and will cause it to shut down if full tank issues arise.
Pros of the Ivation 11 Pint Small-Area Compressor Dehumidifier
Premium RV dehumidifier with superior features
Smart technology that reduces moisture to preferred levels (with built-in alerts)
Built-in ionizer and deodorizer
Continuous operation with overflow hose (auto shut off included)
Only a 1-year warranty
Good for smaller areas only
Overall the Ivation 11 Pint Small-Area Compressor is a top pick RV dehumidifier for good reason. With its superior interface and smart technology, built-in deodorizer as well as overflow system, this is a unit you can rely upon.
Yes it is the most expensive model in our top 7, however the quality performance speaks for itself. A highly recommended option.
The final RV dehumidifier to make our review round up is this offering from Homelabs. This small space option is designed for RVs with a total area of less than 150 sq ft and will comfortable remove up to 250ml of moisture a day.
The tank offers 500ml of storage meaning it will need to be emptied every two days at optimum working levels.
The unit features low noise operation via the thermoelectric Peltier engineering. It is also energy efficient in operation alongside a 25W ETL certified adapter. This also prevents overheating, an important safety requirement in any situation.
There’s an auto-shutoff system built in of course. An LED indicator will inform you when the tank is full.
The unit is also very lightweight making it a good option for your RV. Measuring just 6.5 x 5.3 x 8.5 inches you can easily move it into different areas of the cabin for concentrated results.
Pros of the hOmeLabs Small Space Dehumidifier
Small and portable, great for mobile homes and small RVs
Good performance levels with quiet operation
Auto shut off and safety 25W ETL adaptor included
Some complaints on the construction quality with a minority of units breaking down within a short time of purchase.
Overall the hOmeLabs Small Space Dehumidifier is a worthy addition to our top 7. Especially for those looking for an affordable RV dehumidifier designed for small spaces no larger than 150 sq ft. It does the job.
If you are searching for a dehumidifier to control the moisture in your RV there’s a few things you should consider first.
From the size of your RV, to whether you plan on rigging up a continuous overflow pipe, and a whole lot more besides; your answers to the following factors will help you decide on which is the best model for you and your needs.
So if you are ready, let’s jump to it.
Size of your RV (in cubic feet or sq ft)
Dehumidifiers have a recommended area size that they will comfortably be able to extract moisture from.
This means you need to know the dimensions of your cabin space in order to correctly choose an appropriate dehumidifier.
For example, if you have an RV with 250 sq feet of space inside, a dehumidifier designed to work in spaces up to 150 sq ft will clearly underperform. It will not be able to extract moisture fast enough over the wider area in order to keep your cabin space at optimum levels.
You will find details of the internal space of your RV in the user manual or a Google search of your particular model vehicle.
We recommend that you opt for a dehumidifier where the specification offers at least 50% more power than your needs. A unit designed for spaces up to 250sq ft, will provide great results in an RV with internal dimensions of 150 sq ft for instance.
Extraction rate per day
Beyond the issue of cabin size capability, the performance of dehumidifiers can also be measured in terms of the amount of moisture they can extract each day, (based on specific environmental conditions).
This can range from as little as 9 ounces day, (a rate designed for small spaces) up to 27 ounces per day and more.
Again, this variable is connected to the dimensions of your RV, plus the humidity in the area you either like to travel to or live in.
A large RV permanently situated in Florida will likely need the power of a 27 ounce per day extraction rate.
A small mobile home traveling New England in the autumn, not so much.
Collection Tank size (and optional overflow function)
The collection tank size will impact how often you will need to empty the tank as well as how much space the dehumidifier will take up in your RV.
Tank space is also connected to the extraction rate. Generally speaking, a unit with high daily moisture collection specs will require a large tank to hold all that water.
There’s also the option of fitting an overflow pipe to some model dehumidifier. If you plan on running the unit continuously having this installed is recommended.
All models feature auto-shutoff systems that will turn the dehumidifier off once the tank is full.
The factors to consider here are how often you will be present to empty the tank, whether you aim to have the unit running constantly and if it is possible to use an overflow pipe.
These considerations will help you choose an appropriate dehumidifier for your needs.
A good rule of thumb is that the larger the unit and more powerful the daily extraction rate, the more noise it will make during operation.
That said, models that utilize the emerging Peltier technology will run quieter than most.
User reviews will be helpful in ascertaining the noise levels you can expect. Some units will sometimes offer decibel rates within the specifications too.
Whether you plan on using the dehumidifier throughout the night is an important consideration here. A noisy unit can be found during the day when there are other ambient sounds and you won’t necessarily be spending much time in the cabin, however, at night, that same unit could cause a lot of disturbance.
Again, your specific needs should be considered. If noise levels are important to you, do your research in order to find a reliably quiet dehumidifier.
Extra Features & Usability
Some RV owners will only require a basic dehumidifier that they manually switch on when required, and can rely on the auto-shutoff should the tank get full.
Other users may want a timer function allowing them to set when and for how long the unit is on for.
Different model dehumidifiers will cater to these needs. Along with a whole host of other features.
Smart models will provide precision control over the level of moisture in your cabin, and then will adjust moisture extraction in order to maintain that.
Other units have intuitive LCD controls, and will clearly alert you to the water levels in the collection tank.
Whether you find these features necessary will help determine which model RV dehumidifier to buy.
Finally, there is the important issue of price point. These days you can pick up a quality dehumidifier for small spaces for as little as $50.
However, you can pay over double that for more sophisticated units with superior features and higher extraction rates.
Your needs should determine the amount of money you are willing to spend more than the other way around.
Essentially, it is actually a big waste of time and money to scrimp on the budget and buy a unit not cannot suitable to remove moisture from your cabin space.
The under-par performance will mean you’ll end up spending more money on a replacement dehumidifier.
Evaluate your needs and then focus your price point on units that comfortable meet those needs.
