No matter if we are talking about an RV or a house, we are all looking to save energy. We wonder: is this appliance Energy-Star certified? How many watts does it draw? Will it show significantly on my energy bill? These are all important points to consider. But what if we told you about a dehumidifier that can work efficiently in small spaces without requiring energy at all? Eva Dry E-333’s non-toxic crystallized silica gel technology can remove a maximum of 6 ounces of moisture from the air until it needs to be recharged. While the recharging process does imply plugging it into an outlet, the energy consumed by the heating element is very low, and it doesn’t take long until the silica gel beads become dry again and are ready for a new water removal session. You will never have to renew them and, as this technology is guaranteed to last for up to 10 years, it will take long until you need to replace your unit.

It can cover a space measuring up to 333 cubic feet, so it is more suitable for your RV storage space like cabinets or closets, where it will do a terrific job in removing odors and preventing mold growth. Nevertheless, as these units aren’t expensive, you could buy more of them and spread them around the RV. They are compact, with a height of just 9″, a width of 8.2″, and only 2.9″ thick, so it won’t be difficult to find a good place for them, especially as they come with a hook that allows you to hang them. They are cordless and don’t require a water recipient that could spill. Moreover, as they don’t use a fan, they produce no sound, so you won’t even know they are there.

Two moisture indicator beads will announce when you need to recharge the unit, as it starts on orange and, as the silica beads absorb more and more water, it turns to green. Nonetheless, one charge can last for up to 4 weeks, so you won’t have to perform any daily maintenance as in the case of bucket dehumidifiers that need frequent emptying. Moreover, it is backed by one of the most generous warranties on the market, with 5 years being offered for any manufacturing flaw, so you can purchase with confidence as this is a trouble-free investment.

What we like:
  • Eco-friendly & 100% renewable
  • Compact and lightweight, easy to store in any place
  • Easy maintenance as it only needs to be recharged once every 4 weeks
  • Excellent 5-year warranty
  • One unit can last for up to 10 years
  • Great price
What we dislike:

✖ Suitable only for small spaces

Verdict

Very compact and cheap to run, it will make a great companion for the road. It consumes no energy, and you will only have to spare a few watts once a month to dry the silica beads, so it is probably the most energy-effective dehumidifier you will find on the market. Furthermore, your investment can last for up to 10 years and is covered by a 5-year parts-and-labor warranty, which is more than generous if you consider the price.

  • Weight: 1.87 pounds
  • Warranty: 2-year


Measuring only 8.5 inches in height, 6.5 inches in width, and 5.3 inches in length, it is perfect for small RVs, where space is usually a problem. In fact, it was built to cover narrow spaces with a surface of only 150 sq ft, where it can run at its maximum capacity and draw up to 9 oz of dampness per day. The water is stored in a 16 ounces reservoir, which is placed on the front for easy access. It can be detached and emptied in minutes, an operation that doesn’t need to be performed more often than once every 2 days. Plus, if you are not around when the water tank gets full, there’s no worry, as the auto shut-off will instantly turn off the device.

It offers only one speed setting, as it works on Peltier technology and doesn’t include a fan. The good news though is that it is extremely quiet, as all the components are tightly fixed and vibrations are reduced to a minimum. To power it on, you will only have to plug it into a 110V outlet and press the on/off switch. This is the only control available, therefore you don’t get too much control of the functions. Nevertheless, the simple design has its advantages. First of all, there’s no risk of spending hours trying to figure out how everything works. Secondly, the power consumption rate is significatively lower at 25 watts, as there’s no fan, no LED or LCD screen, or fancy functions that need extra energy. Last but not least, it is lighter at only 1.87 pounds and can be easily carried around. It does feature an indicator light, though, that turns on when the water recipient is full.

Regarding maintenance, we should state that it doesn’t require a filter, so you won’t have to deal with periodical filter washing or replacement. Moreover, the exterior is easy to clean with a cloth once a week, and the water recipient can be thoroughly washed and rinsed when emptying it to prevent mold and bacteria growth and the development of unpleasant odors. Additionally, if a mishap shall occur within the 2-year span given by the manufacturer, you will get free repairs or full replacement of the unit.

What we like:
  • Low energy consumption
  • Low noise level
  • Easy maintenance
  • Compact design
  • Great 2-year warranty
What we dislike:

✖ Suitable only for small spaces

✖ Needs to be shut off every 12 hours to avoid overheating

Verdict

It is a great choice if you are looking to dehumidify small spots in your RV, like the bathroom or the cooking area. It is lightweight and compact, so easy to carry around. Plus, with a very low sound level, it is almost unnoticeable no matter the spot you choose for it.


7. Eva-dry Edv-1100 – Best for Low Temperatures



Specifications:


  • Room Coverage: 1,100 cu. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 8 ounces/day
  • Water Tank Capacity: 16 ounces
  • Speed Settings: 1
  • Noise Level: 50.9 dB
  • Rated Power: 22 watts
  • Filter Type: Filter-free
  • Controls: On/Off Switch
  • Auto Shut-Off:

  • Timer:
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: 23℉ – 95℉
  • Power Cord Length: N/A
  • Continuous Drain Option:
  • Dimensions: 6.5 x 8.5 x 5.3 in.
  • Weight: 1 pound
  • Warranty: 1-year


It is a very popular choice among RV owners, not only for its compact and portable design that makes it suitable for narrow spaces but for its ability to continue working even when the temperature outside drops down to 23 degrees Fahrenheit or raises to a maximum value of 95 degrees Fahrenheit. It doesn’t require an auto-defrosting function to maintain its internal components intact, as the advanced Peltier technology is known for its ability to resist extreme temperature conditions. Thus, it is the best choice if you are traveling during the cold season or wish to maintain an optimal humidity level in your RV while in storage.

It is more suitable for small RVs or for removing moisture in a single room as its maximum coverage reaches only 1,100 cubic feet. However, its action in this space is surprisingly performant, as it can draw up to 8 ounces of water per day. The 16 ounces water tank is generous and doesn’t need to be emptied daily. As a matter of fact, it may take days until the indicator light lets you know that the tank is full, especially if the environment in your RV is not particularly humid. Moreover, in terms of energy consumption, it is one of the most efficient on the market, with a 22 watts rate that allows you to run it the whole day without significant energy costs. Nonetheless, you should remember to turn it off every 12 hours as the manufacturer recommends to prevent overheating.

It lacks a timer, but the auto shut-off function is present, so accidental spills or fire hazards are out of the question. The controls are almost inexistent, with a single on/off switch included for safety purposes. However, there’s something that distinguishes this unit among the others, and this is the sturdy construction. We have noticed that it is built of superior-quality materials that are resistant to wear and can last through the years. Besides that, it is covered by a 1-year warranty that needs to be activated within 30 days from the date of purchase, and which, according to customers who have already tested this model, is quickly honored by the manufacturer.

What we like:
  • Straightforward design
  • Durable structure that can last under extreme temperature conditions
  • Energy-efficient
  • Auto shut-off function
  • Compact
What we dislike:

✖ Can get pretty loud at 50.9 decibels

✖ Can make a difference but only in small spaces

Verdict

To summarize, it is perfect if you are traveling in an area with a cold climate, but one unit might not be enough for a large RV, so you should consider investing in two, as most dehumidifiers that can cover larger spaces usually cannot work under 41 degrees Fahrenheit. Moreover, even two units running at the same time won’t draw more than 50 watts, so you will save energy and money in the long run.


6. Pro Breeze FBA_PB-03-US – Best for the Money



Specifications:


  • Room Coverage: 220 sq. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 18 ounces/day
  • Water Tank Capacity: 52 ounces
  • Speed Settings: 1
  • Noise Level: 40 dB
  • Rated Power: 40 watts
  • Filter Type: Filter-less
  • Controls: On/Off Switch
  • Auto Shut-Off:

  • Timer:
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: 59℉ – 86℉
  • Power Cord Length: 6 feet
  • Continuous Drain Option:
  • Dimensions: 6.6 x 9 x 12.7 in.
  • Weight: 5.09 pounds
  • Warranty: 1-year


It is a practical model that comes at a great price and with excellent customer reviews. Built on the thermo-electro Peltier technology, it is super quiet, with a peak noise of only 40 decibels, so if you are looking for a unit that can work during nights and draw the moisture out of your RV’s bedroom, we recommend it. It is built of resistant plastic and comes with a generous tank that can hold up to 52 ounces of water. It may not seem a lot, but you should consider that it was designed for small spaces with a surface smaller or equal with 220 square feet, where it can remove up to 18 ounces per day. Therefore, in this case, the tank doesn’t need to be emptied once or several times a day, a feature that makes it very convenient.

It uses a compressor to absorb moisture, so the power consumption rate remains around 40 watts as there’s no fan involved that could draw more energy. Nevertheless, this could be an inconvenience if you are looking for customization, as it offers only one speed setting. The controls are straightforward, and by this, we mean that it includes an on/off switch and an indicator light that lets you know when the water reservoir is full. On the other hand, the tank is easy to remove and comes with a plug on the bottom for easy water removal into a sink or a drain. The large opening makes it easy to perform periodical cleaning, which is recommended to prevent mold and bacteria growth.

It can operate at temperatures of 59 to 86 degrees Fahrenheit, so it isn’t suitable for use in cold climates or in environments where the temperature drops under 41 degrees Fahrenheit. But it is a great choice for spring, summer, and fall RV trips, as it is super compact, measuring only 12.7 inches in height, 9 inches in width, and 6.6 inches in length. The small dimensions and reduced weight make it easy to carry around and position in narrow spaces, especially as it features a 6-foot power cord that allows you to find a safe spot for it. Although it lacks a timer, it does come with an auto shut-off function that prevents it from spilling the water when the reservoir is full. Moreover, in case a mishap occurs or you discover a manufacturing flaw that prevents it from running as it should, you have got 1 year from the date of purchase to get it fixed or replaced for free.

What we like:
  • Small dimensions make it easy to transport and store
  • Super-quiet compressor
  • Auto shut-off
  • Excellent quality-price report
  • Low energy consumption rate
What we dislike:

✖ Cannot be used at temperatures lower than 59 degrees Fahrenheit

Verdict

It is a great investment if you own a small RV or looking to cover one room at a time. It can work quietly for days before you need to empty the generous water reservoir. Moreover, it is energy-efficient and doesn’t imply supplementary filter replacement costs, so it is cheap to run. Not to mention that maintenance is a breeze, as the water tank has a large opening and comes with a plug for easy emptying.


5. Ivation IVADM35 – Best for Full-Time RV Living



Specifications:


  • Room Coverage: 2,200 cu. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 20 ounces/day
  • Water Tank Capacity: 68 ounces
  • Speed Settings: 1
  • Noise Level: Low
  • Rated Power: 72 watts
  • Filter Type: Filter-less
  • Controls: On/Off Switch
  • Auto Shut-Off:

  • Timer:
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: N/A
  • Power Cord Length: 6 feet
  • Continuous Drain Option:
  • Dimensions: 9.6 x 14.1 x 7.2 in.
  • Weight: 4.85 pounds
  • Warranty: 1-year


If the RV is your house, you are probably looking to make it as comfortable as possible without increasing your energy bills too much. In this case, this dehumidifier from Ivation offers the best balance between performance and costs. It was designed to cover small spaces with a volume of up to 2,200 cubic feet, therefore it is more suitable for trailers than motorhomes. Nevertheless, if you place it in the bathroom or cooking area, where the humidity is the highest, you can increase its efficiency and solve the problem. It comes with a medium-size 68 ounces water reservoir and can draw up to 20 ounces of moisture per day at a low 72 watts power consumption rate, so, although it hasn’t been Energy Star certified, it is energy-efficient.

Strongly-built and running on Peltier technology, it is both quiet and resistant to external factors like increased humidity or temperature variations. It is easy to maintain as well, as the water tank is removable and offers a large opening for cleaning and emptying. An indicator light lets you know when the tank is full and, if you miss the signal, the auto shut-off function is ready to kick in and shut everything down so the water doesn’t spill and cause electrical damage. Regarding dimensions, which are important as it will become a permanent part of your wheelhouse, we should mention that it is very compact and lightweight, with a height of only 14.1 inches and a small footprint measuring 9.6 x 7.2 inches. The weight is only 4.85 pounds.

The convenience is increased by the long 6-foot power cord that allows for easy positioning of the device. It is easy to control, as it only features an On/Off switch for quick powering on and off. On the other hand, it doesn’t incorporate a fan, so you have no control over its speed. Nevertheless, the lack of a fan is what makes it extremely quiet, so we think this is a worthy-to-make compromise. Besides that, we should remember that fans require more energy to run, and this will show up on your bills if you use it continuously.

What we like:
  • Low energy consumption makes it suitable for long-term use
  • Compact and easy to move around
  • Super-quiet as it doesn’t include a fan
  • Water tank is easy to clean due to large opening
  • Great 1-year warranty
What we dislike:

✖ Not suitable for cold environments

Verdict

It is small but strongly-built and up for years of run, so your investment will surely pay off. We liked that it works quietly and has a low power consumption rate that makes it the perfect choice for continuous running. Furthermore, it has a simple and clean design that will immediately blend in with the décor, while the small footprint won’t cut too much in the already reduced space.


4. TOSOT 1,500 Sq. Ft. 30 Pint – Best for Winter RV Storage



Specifications:


  • Room Coverage: 1,500 sq. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 30 pints/day
  • Water Tank Capacity: 8 pints
  • Speed Settings: 3
  • Noise Level: 44 – 48 dB
  • Rated Power: 296 watts
  • Filter Type: Washable filter
  • Controls: Digital
  • Auto Shut-Off:

  • Timer: 2 – 4 hours
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: 41℉ – 90℉
  • Power Cord Length: 6 feet
  • Continuous Drain Option:
  • Dimensions: 15 x 11.7 x 20.7 in.
  • Weight: 34 pounds
  • Warranty: 1-year


Storing the RV for the winter means more than sheltering it in a garage or parking it in a spot that can provide as much protection as possible against winds, snow, and freezing. You must consider the effects cold weather can have on the interior, where humidity starts to build up, especially as windows cannot be opened in this season. Thus, to maintain everything under control, we recommend this unit from TOSOT, which proved to be the best for this task from multiple points of view. First of all, it is capable to provide excellent dehumidification for an entire motorhome, as it was designed to cover spaces as large as 1,500 square feet. Secondly, the dehumidification rate is amazing at 30 pints per day, so it can easily face even the most humid environments. Last but not least, and this is essential, it can run at low temperatures down to 41 degrees Fahrenheit and comes with an auto-defrost function that prevents the internal coils from freezing.

It includes an 8 pints bucket, which is rather small for its capacity, but the good news is that it offers a continuous drain option, so you can just connect a garden hose to the special nozzle and direct the water to a garage floor drain or an outdoors drain. It is highly independent, with an auto-restart function that saves your last settings in case of a power outage and sets it going as soon as the power is back on. Furthermore, it includes a timer that can be set for 2 or 4 hours, perfect if you don’t want it running continuously. Nevertheless, we noticed that it lacks an auto mode, which is present in higher-capacity TOSOT dehumidifiers, so you will have to set the speed manually. The digital panel will help you select either low, medium, or high speed that will generate different sound levels and power consumption rates.

With a height of 20.7 inches and a footprint of 15 x 11.7 inches, we can place it among medium-size models that occupy some of the RV’s floor space. Nevertheless, we must consider that it was designed for motorhomes, where it is easier to spare it. Regarding maintenance, the only things that need to be performed regularly are the cleaning of the water tank and the washing/replacing of the mesh filter, two simple operations that will keep it in good shape and increase its lifespan. Moreover, for eventual mishaps or manufacturing flaws, the manufacturer offers a 1-year warranty and friendly customer support.

The peak sound it can reach is 48 decibels, which is under the noise level of a normal conversation. Moreover, if you decide to set it running at the lowest speed, you won’t even know it’s there during the summer holidays when we assume you will take it with you. In terms of costs, we should mention that it has been Energy Star certified and draws a maximum of 296 watts. It may seem high compared with the previous models, but the truth is that, for its size and capacity, it is one of the most energy-efficient units.

What we like:
  • Works in low-temperature conditions that can drop as down as 41 degrees F
  • Auto-defrost function
  • Auto-restart function
  • Continuous drain option
  • Offers humidity readout
  • Features a timer
What we dislike:

✖ The 1-year warranty is rather short for the price

✖ Some customers complained that it doesn’t come with instructions

Verdict

Overall, it offers great value and it was surely made to last. It comes with an intuitive digital panel and offers multiple smart functions, designed to increase its independence and reduce your efforts. It is energy-efficient and allows you to customize both fan speed and run time so you can save money when the humidity remains within normal limits. Moreover, it comes with a continuous drain option that allows you to remove water directly into a drain, so it is extremely convenient.


3. Vremi 30 Pint 1,500 Sq. Ft. – Best for Large RVs



Specifications:


  • Room Coverage: 1,500 sq. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 30 pints/day
  • Water Tank Capacity: 8 pints
  • Speed Settings: 2
  • Noise Level: Low
  • Rated Power: 270-600 watts
  • Filter Type: Permanent metal dust filter
  • Controls: Digital
  • Auto Shut-Off:

  • Timer:
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: Down to 41℉
  • Power Cord Length: 6 feet
  • Continuous Drain Option:
  • Dimensions: 16.1 x 10.4 x 19.9 in.
  • Weight: 33.1 pounds
  • Warranty: 1-year


It is a very popular choice and many customers confessed that it does an excellent job removing moisture from their RVs. The large 1,500 square feet area coverage makes it suitable for both trailers and motorhomes where it can work continuously to remove up to 30 pints of moisture per day. It comes with a large 8-pint removable bucket, which is great if you can’t evacuate the water outside. Nevertheless, you should know that the alternative is possible as it offers a continuous drain option. You just need to provide the garden hose, which isn’t included.

The digital panel is positioned on the top side and offers easy access to the functions. Here you can set fan speed, by choosing either normal airflow or turbo, or activate the timer, which will power off the unit after a period and reduce energy consumption. You can monitor the smart functions as well, as an indicator led will let you know if the auto-defrost function has kicked in or the auto shut-off function has paused the operations when the bucket is full. Another attractive function is the auto-restart, which activates during power outages, saving the last settings. As soon as the power is back on, it will automatically restart the dehumidifier, and it will continue its activity.

The power consumption rate can reach 600 watts on the turbo speed, but we doubt that you will need to run it at this level for long periods. At normal speed, it draws 270 watts, which is a decent value for such a high-capacity device. As a matter of fact, it has been Energy Star certified, so it is considered energy-efficient. Moreover, you can rest assured that in case a mishap occurs, you won’t need to invest in repairs, at least not for 1 year, during which the manufacturer offers to solve them for free.

Although it is a bit bulky, with a height of 19.9 inches and a footprint of 16.1 x 10.4, the housing is sturdy and resistant to long-term use. The water bucket features a transparent window that allows you to monitor the water level. Furthermore, it is easy to remove for emptying and provides excellent access for cleaning as it features a large opening. The long 6 feet power cord allows you to find a good spot for it, so you won’t need to invest extra money in an extension cord. Moreover, as the filter is washable, if you clean it regularly, it can last for years, saving you of other expenses.

What we like:
  • Large area coverage
  • Multiple smart functions
  • User-friendly digital panel
  • Continuous drain option
  • Resistant to low temperatures
What we dislike:

✖ Rather bulky

✖ Can get expensive if ran on turbo speed for long periods

Verdict

This is the best option for motorhomes, as it can provide excellent coverage for the entire space. We liked that it is quiet and can continue its activity even when the temperatures drop down to 41 degrees Fahrenheit. Furthermore, we have appreciated its sleek design which, although it is a bit bulky, won’t ruin the décor.


2. hOmeLabs HME020030N 1,500 Sq. Ft – Editor’s Choice



Specifications:


  • Room Coverage: 1,500 sq. ft.
  • Dehumidification Rate (2012 DOE Rating Standard): 30 pints/day
  • Water Tank Capacity: 8 pints
  • Speed Settings: 2
  • Noise Level: up to 54.5 dB
  • Rated Power: 602 watts
  • Filter Type: Washable filter
  • Controls: Digital
  • Auto Shut-Off:

  • Timer: 24-hour
  • Energy-Star:
  • Bucket Full Indicator:
  • Operating Temperature Range: Down to 41℉
  • Power Cord Length: 6 feet
  • Continuous Drain Option:
  • Dimensions: 15.2 x 10 x 19.7 in.
  • Weight: 30.5 pounds
  • Warranty: 2-year + 6-month if registered


Reliability is the keyword for this dehumidifier, and most customers go for it when they need to cover large areas. It has a solid construction and high-quality internal coils, designed to ensure and maintain the performance over the years. Nevertheless, the design hasn’t been neglected, and we were impressed by its clean housing that rests on sturdy wheels and sleek digital panel that allows for easy access to controls and smart functions. A handle has been included as well for easy manipulation, therefore, although it is a bit bulky, with a footprint of 15.2 x 10 inches and a height of 19.7 inches, it isn’t difficult to reposition or move around the RV.

In case of a power outage, it can save the last settings and restart automatically once the situation is solved. Moreover, it will automatically defrost if the temperature drops as low as 41 degrees Fahrenheit to prevent the coils from freezing. If you don’t notice that the bucket is full, it will activate the auto shut-off function, so you will never have to deal with accidental spills. Additionally, it offers a timer that can be set for up to 24 hours. What we noticed thou is that it isn’t the quietest on the market, especially if you run it at the highest speed, where it can reach a noise level of 54.5 decibels. Nonetheless, on continuous or comfort mode the noise drops considerably and, according to their reviews, becomes unnoticeable to most users.

In terms of performance, we should mention the strong built-in pump compressor, which can remove up to 30 pints of water per day in a space measuring up to 1,500 square feet. Nevertheless, the smart functions are the ones that make it stand out, so we should take a moment and analyze them. The first time you will plug in the unit, it will start on the continuous mode which works best if you match it with the continuous drain option. Thus, the water will be evacuated outside, and you won’t ever need to empty the bucket. If this option isn’t available for you, you can easily turn off this mode by touching the continuous key and use the left-right arrows to set the desired humidity level. By selecting the comfort mode, you will allow the unit to monitor the humidity in the RV and automatically adjust the fan speed. Manual speed adjustment is available as well, and you can set it to run either on normal or turbo speed.

The maintenance is easy to perform, as the 8-pint bucket is removable and features a large opening. The filter is washable and can be easily detached from its place. Regarding the power consumption rate, it is rather high, but only on turbo speed, where it can reach 602 watts. On continuous run it is comparable with the energy drawn by the previous model. Nevertheless, the warranty is better, with 2 years being offered for repairs and 6 extra months if you register on their website.

What we like:
  • Excellent dehumidification rate
  • Easy maintenance
  • Advanced customization options
  • Generous warranty
  • Auto-restart function
What we dislike:

✖ Turbo speed generates high energy consumption and noise

✖ Large footprint

Verdict

In conclusion, it is worth buying if you own a motorhome. With its high moisture removal capacity and strong fan, it will cover all the space and won’t allow humidity to build up and release the mold and mildew plague. Furthermore, as it features an auto mode, an auto-restart function, auto-defrost, and continuous drain, your work will be reduced considerably, and you will be able to enjoy your vacation without thinking about small buckets that need to be emptied daily.

When it comes to dehumidifiers, Frigidaire is the first among customers’ choices, no matter if they pick it for their homes, basements, RVs, or commercial activities. The brand produces models in different sizes that can provide proper coverage for every space, and we have chosen the 30-pint model as the most suitable for trailers and motorhomes. It is performant but quiet and offers excellent area coverage. Moreover, although it is a bit bulky, most buyers find it sleek and easy to blend in with the décor.

Perfect for Motorhomes

When they think about a dehumidifier for RV, most customers have in mind a compact unit that can be easily lifted and moved around. But we must admit that such a small unit is unable to cover the space of a motorhome. This model, on the other side, was specially designed to deal with high humidity levels and comes with a strong fan and superior features that make it suitable for larger RVs:

  • Large area coverage – it can provide efficient dehumidification in a space as large as 1,500 square feet
  • High water removal rate – it can collect up to 30 pints of water per day, being perfect for very humid environments
  • Continuous drain option – allows for easy water evacuation outside of the RV
  • Energy-efficient – is Energy Star certified and has a maximum power consumption rate of only 320 watts

The bucket is generous and can hold up to 7.6 pints of water, so it is a great alternative to continuous draining but only if the environment isn’t particularly humid. Otherwise, you will have to empty it several times in a day and this can become a struggle. On the other hand, it does offer a timer, so you can shorten its operation time and reduce your effort.

Smart Technology

We must admit that the price you pay is mostly for the high-quality construction that makes it durable and able to run for years, but the smart functions are part of the costs as well. They make it convenient and comfortable and save you a lot of trouble, so let’s take a good look at them:

  • Auto shut-off – activates when the bucket is full and turns the unit down, thus preventing the water from being spilled on your floor or carpet
  • Digital humidistat readout & control – it constantly monitors the humidity in the RV and can adjust the fan to reach the value you choose
  • Auto-restart – kicks in only if a power outage occurs and restarts the unit afterward, allowing it to continue its program from where it has left it

It offers 3 speed settings that produce variate airflows and noise levels. Nevertheless, the maximum it can reach is 52 decibels, and this only at the highest speed. We have appreciated that it can work in low-temperature conditions (down to 41 degrees Fahrenheit) but we noticed that it doesn’t feature an auto-defrost function, which would have been useful during the winter.

Convenience at its Best

The water bucket is placed on the front side for easy access and is provided with a handle and a splashguard. Therefore, it can be quickly removed and carried to the sink without the risk of spilling the water. Retrieving the filter and washing it couldn’t be more effortless. Not to mention that, although it weighs 34 pounds and has a height of 20.5 inches, it is easy to reposition and transport, as it comes with wheels, a top handle, and two integrated side handles. Plus, the manufacturer offers a great 5-year warranty for the sealed system and 1-year warranty on the components, so you will be covered in case of malfunctions.

What we like:
  • Offers efficient dehumidification for large spaces
  • Easy to transport as it comes with wheels and 3 handles
  • Smart functions make it safe and easy to use
  • Energy Star certified
  • Durable construction
  • Generous warranty
What we dislike:

✖ No auto-defrost function

Verdict

All in all, this is the best you can get for your RV at the moment. It is a strongly-built unit that has been tested by tens of thousands of customers and has received excellent reviews. It comes with a strong fan and smart technology that make it highly-customizable and easy to use. Moreover, it is easy to maneuver, as it comes with wheels and side handles.

Conclusion

We’ve got the end of our analysis in which we tried to cover as many aspects as possible. Although we have chosen only high-quality products, we kept a keen eye for both their qualities and flaws, so you can make an accurate comparison and pick exactly what you need. Nevertheless, apart from price, structure, and performance, other criteria need to be considered, and, this time, it is your turn to make your own ranking according to your budget, preferences, and RV type.

Best Dehumidifier for RV on the Market: Frigidaire FFAD3033R1 30-Pint

It is a top-quality unit and a customers’ favorite, so there’s no chance you could go wrong with it, as everything has been carefully crafted, starting with the sleek housing and user-friendly control panel and ending with the easy-removable water bucket with handle and splash guard. You get an auto shut-off function, auto-restart, and even an auto mode that makes it extremely convenient. Not to mention that it has an excellent dehumidification rate that makes it suitable for motorhomes.

Editor’s choice: hOmeLabs HME020030N 1,500 Sq. Ft

Our runner up and favorite distinguishes among its competitors through a clean design and excellent water removal capabilities. It can stand winter cold, as it comes with an auto-defrost function that keeps the coils from freezing when the temperature drops down to 41 degrees Fahrenheit. Furthermore, it will restart on its own if a power outage occurs and will shut itself down when the water bucket is full, so it is both safe and convenient.

Best Dehumidifier for Large RVs: Vremi 30 Pint 1,500 Sq. Ft.

It is easy to observe that only a bigger dehumidifier can deal with a whole motorhome, so the bulky design is difficult to avoid in this case. Nevertheless, you can go with a sleek model like this one and get both performance and a flawless décor. It offers continuous drainage and comes with a generous 8-pint bucket in case the first variant isn’t available. Besides that, functions and settings are easy to control, as it features an intuitive digital panel.

Best RV Dehumidifier for the Money: Pro Breeze FBA_PB-03-US

An affordable option that is both quiet and cheap to run, this model offers the best quality-price report. It is built of high-quality materials that make it resistant over the years and can provide great dehumidification for small RVs or individual rooms. Moreover, as it is equipped with a generous water recipient, it is both easy to empty and clean and doesn’t require daily maintenance.

Best RV Dehumidifier for Winter Storage: TOSOT 1,500 Sq. Ft. 30 Pint

Multiple features recommend this model as the best for winter RV storage. As we have mentioned before, it comes with an auto-defrost function that doesn’t allow it to freeze even when the temperatures get as low as 41 degrees Fahrenheit. A second feature that is worthy to mention is its ability to operate continuously due to the continuous drain option. Furthermore, it comes with an auto shut-off function, auto restart, and a timer, 3 functions that make it highly independent, saving you from tiring supervision.

Best RV Dehumidifier for Full-Time RV Living: Ivation IVADM35

When selecting this model, we took into consideration its ability to perform at a low power consumption rate and its coverage capacity, which is great for trailers or even for motorhomes if you purchase 2 units. Nevertheless, it is not only cheap to run but super quiet, an important quality as it is going to be used continuously in a wheelhouse. Besides that, it is small and lightweight, so you will easily find a good place for it in your RV.
