RV Dehumidifiers Reviewed

hOmeLabs 4000 Sq Ft Dehumidifier 70 Pint Energy Star

A strong contender for the number one spot, this RV dehumidifier is a worthy match with its 1.6 gallon water storage capability, it also removes up to nine gallons of moisture a day.  

This unit is great for larger RV’s that have plenty of space to dehumidify. A good added benefit is that it won’t cost you any more money to run than the previous portable dehumidifier, and this product is so quiet you can hardly hear it running.

You can set the humidity you want your room to be and won’t have to worry about it until its full but not for a full 24 hours. Of course, no one wants to be constantly emptying out the liquid from the storage tank, and this RV dehumidifier has a hose attachment so you can continuously drain any fluid.

The hose, of course, doesn’t come with it, but the company does recommend “a ⅝ diameter garden hose with a female threaded end, and optionally Teflon tape for extra security.”

This unit also has a neat added feature called ‘Turbo mode’ which makes the fan speed increase from 165 cubic feet per minute to 188 CFM for maximum moisture removal and odor reduction.

Bottom Line

This model is up there with the best RV dehumidifiers. It has a great 24-hour operation life until it fills up. That said, if you want it to be on constantly without having to empty it, you could just set up the hose to drain continuously.

The turbo mode is something that makes it stand out from the crowd, this thing truly is a beast at dehumidifying the air. The only downside we see to this model is its size. The RV dehumidifier is pretty big and wont easily blend into the background. And depending on the size of your RV, you might be better looking for something smaller.

Vremi 30 Pint Portable Dehumidifier

This portable dehumidifier can hold up to four gallons and is certified to absorb moisture fast and effectively with minimum energy consumption. This gadget is best used in medium to large sized RV’s.

If you want a mix of high performance and portability, this is the dehumidifier for you. Easily moved about with the addition of some wheels, and again, this dehumidifier will get rid of all that moisture and humidity without any irritating noises.

Like the hOmeLabs 4000 Sq Ft Dehumidifier above, this dehumidifier has a turbo mode that will increase your fan speed from a standard setting of 129 CFM to a boosted speed of 138 CFM for maximum effect. You can also choose the humidity on it, and keep it on continuously to drain the liquid so you can have it running 24/7, all you need is a standard gardening hose with a female threaded tip.

Bottom Line

This handy portable dehumidifier is easily one of the better versions on the market. It’s portable with the help of some wheels, it gives you the option to attach a hose for continuous usage, and uses minimum amounts of power even when turbo mode is switched on.

The only real downside to this product is that although it is a portable dehumidifier, it’s still a bit chunky and it could be hard to find a decent spot for it to blend in.

Pro Breeze Electric Mini Dehumidifier, 1200 Cubic Feet

The best-rated RV dehumidifier on Amazon at the moment, the reviews reflect on how reliable this dehumidifier is. Small and compact, this portable dehumidifier can remove up to nine ounces of water per day with a storage capacity of 16 ounces.

This model will automatically shut off when full and will need to be emptied, it doesn’t offer a continuous drainage option like most of its competitors.

Thanks to its size, the device will easily blend into its surroundings. Actually, it’s about the same size as your average plant pot and looks just like an air freshener. Another added bonus for this portable dehumidifier is that it’s silent and doesn’t give off any irritating noises.

Judging by the reviews on Amazon, this product is one of the favorites for any RV/Caravan owners, mainly because of its size, but still getting the job done effectively.

Bottom Line

As well as being quiet when switched on, this RV dehumidifier is a simple solution to your humidity problem.

It might be reliable, but it does have a minimal amount of features. It has to be drained manually every two days, which might seem decent but it does only collect 9 ounces of moisture per day. Not the most advanced model, but if you want something simple and does its job, this might be the gadget for you.

Ivation 11 Pint Small-Area Compressor Dehumidifier

This is the best and most compact RV dehumidifier on the market at the moment, it has everything the previous dehumidifier was missing. It can remove up to 11 pints of water per day with a storage capacity of 2 liters. Even though it fills up fast, you won’t have to drain it manually as it comes with its own automatic drainage hose so it can work around the clock.

The smart technology built into the portable dehumidifier allows you to not only view the current humidity in your RV but also set it to your desired level. This model will enable you to set a time up to 24 hours away so you can just leave it and let it do its thing throughout the day.

Not only is this a fantastic dehumidifier, but it also has a built-in Ionizer, which purifies the air around you, leaving you feeling all energized.

Bottom Line

A small and reliable unit that has plenty to offer, the automatic drainage allows you to run the dehumidifier regularly without having to worry. An added bonus is that it already comes with its own hose and bucket, so there’s no need to buy your own, a rarity for most portable dehumidifier units.

The built-in humidity settings allows you to choose the level of humidity you want, the same goes for the timer. Not only can this dehumidify your RV but it also cleans the air around you with its top of the range Ionizer.

The only real downside to this unit is that its small, but not small enough for those hard to reach places. Mold and dampness can be anywhere, a closet, for example, might be hard to reach and could warrant the use of an even smaller dehumidifier.

Ivation IVADM35 Thermo-Electric Dehumidifier

Just like the smaller version we spoke about previously, this 12v dehumidifier has no moving parts and is nice and quiet. The unit can bring in a maximum of 20 oz of water a day with a total capacity of 68 oz, at which point it will shut off automatically.

Unlike the smaller model, this unit doesn’t come with a hose, bucket or an automatic drainage option, meaning that you’ll need to do it manually. This isn’t too much of a problem as it usually take three days to fill. You have the option of choosing the humidity setting you’d like, and once this has been reached, the device will automatically shut off.

Bottom Line

Taking up to three days before filling up, the RV dehumidifier certainly does its job collecting up to 20 oz of water per day. No more sleepless nights and no dealing with a noisy machine, this unit has no moving parts, and thanks to its in-built humidistat you have control over the humidity setting.

These are the best features of this portable dehumidifier. And despite not having the ability to drain like the company’s smaller model automatically, it still packs a punch and can be relied upon. One complaint that cropped up a few times on Amazon was about the power cable. Apparently, it’s easily broken and can be heavy when trying to move about.

Tosot 70 Pint with Internal Pump 4500 Sq. Ft.

A large unit, this electric RV dehumidifier sits at a whopping 51 pounds, so it’s safe to say that it can take a hit or two. Despite its weight, it can be moved about easily on its four wheels. And for something so big it’s not too noisy either, as the noise proof components help it blend perfectly into RV life.

The smart panel allows you to change a few details such as the humidity setting. Other features include a timer of up to four hours and the continuous draining option.

The dehumidifier removes up to nine gallons per day and has a bucket capacity of 160 ounces. To get continuous drainage, just connect a standard ¾ inch hose to the unit, then the other end to a drain and select the non-stop setting.

Bottom Line

The good outweighs the bad on this portable dehumidifier, as it works effortlessly to bring in up to nine gallons per day, all the while nice and quietly. The timer and humidity settings are also a useful feature, the only downside about the timer is that you can only set a maximum of four hours.

Other than that, if you decide to carry your portable dehumidifier somewhere and for some reason, the wheels aren’t working, it can be heavy for some.

The company designed this dehumidifier to be portable and easy to move about considering it isn’t the smallest of units. The dehumidifier is also Energy Star certified, so there’s no need to worry about racking up a massive electricity bill.

The reservoir can be drained via a hose pipe, meaning that it can run 24/7 while draining water. The only two complaints are that it doesn’t already come with a hose like some of their competitors. And although it’s portable, you might still need to sacrifice vital space in a smaller RV. Therefore, it’s probably best used in medium to large RV’s.

New and Improved Eva-dry E-333 Mini Dehumidifier

Using no batteries or fancy flashing lights, this portable RV dehumidifier is 100% renewable unit that uses silica gel technology. The fancy little dehumidifier can be placed in any small rooms and is fit for even a bedroom of an RV or any area up to 333 cubic square ft.

What Makes The Best RV Dehumidifier?

Like all products we buy, there’s always one with unique features that makes it stand out from their competitors, something that gives it an extra advantage. The same goes for RV dehumidifiers. Features such as continuous drain capabilities, anti-frost technology, auto settings and a timer all would give any dehumidifier an advantage over their competitors.

Constant Drain Facility

This feature allows you to have your portable dehumidifier on 24/7 without having to empty it once full. A hose can be connected to your dehumidifier which can then be connected to a compartment within your RV or just a simple box where the excess fluid will end up.

Anti-Freeze Technology

Because of the cold air and moisture running through the device, the coils might freeze over. This is more of a problem for refrigerant models rather than desiccant ones.

Auto Humidistat

Being able to set what humidity you want in your RV and leaving it on throughout the night is a life-saver. With a regular dehumidifier, you’d need to keep getting up throughout the night to switch it on again. This auto setting will keep the humidity to a pre-selected level.

Timer

The timer on a portable dehumidifier is a neat feature that you can use to make heading to bed more comfortable. Just turn your dehumidifier on and set the time to an hour or so and you’ll fall asleep like a baby. If you want it running for only a few hours to save on power, you can set it to switch off roughly two or three hours after you expect to be asleep.

Types of RV Dehumidifiers

Below are the two main types of portable dehumidifiers you may want to consider adding to your RV:

Desiccant

These types of dehumidifiers are filled with a water absorbing material that will extract any moisture from the air that passes through the device. This type of unit doesn’t need a power source or to be emptied regularly. Once they’re full either a small light or change in color of the crystals will let you know it’s full. Plugging it into a socket will dry it out via the heat created by the electricity. When empty, it will return to the original color.

Refrigerator

Air filled with moisture is sucked into the dehumidifier and passes over a cold coil. Then the air is condensed on the coil which then turns into water droplets, which collect in the water tank. The same air then heads over a hot coil, which in turn is sent out of the unit, producing dry air.
