Why Would You Want a New Dehumidifier For Your RV?

We’ve already said that RVs are prone to humidification a lot more than any other vehicle. But how exactly? An RV is basically a second home while you’re on the road. It’s a recreational vehicle where you’ll find yourself performing all of your day-to-day activities from cooking to bathing.

All such activities being performed in a closed vehicle would lead to eventual accumulation of water vapors within the RV. This happens a lot faster than you can imagine, given the smaller size of the vehicle.

All these accumulated vapors not only make breathing uncomfortable but also affect the soft furniture in your RV. Not to mention the problems that may arise with mold around the vehicle!

To avoid these problems, it is best to invest in a good dehumidifier. The device will save you from a number of issues and expenses that you may face later on without a dehumidifier.

Aspects to Consider Before Buying

There are a number of dehumidifiers in the market, and a lot of good ones too. But not every good dehumidifier is going to work for you. There are some aspects that you need to carefully look at before you buy a dehumidifier for your RV.

Space in the RV

The foremost aspect to consider is the space in the RV that needs to be humidified. Once you’ve considered the space in the RV, you’ll have a general idea of what sort of dehumidifier you need to purchase because certain devices are designed to dehumidify smaller spaces while others work just as efficiently in larger areas.

Portability of the Device

It is also important to make sure that the model that you pick for your RV is portable. Since you’re always on the go in the RV, you might need to move around the device with not much energy to spare on such tasks. It is therefore crucial that your picked model is portable and convenient to handle.

Easy to Install & Control

The device that you pick also needs to be easy to install and control. If this aspect is overlooked, you might have a hard time setting it up, and all your dreams of using the device right out of the box will be long gone. You do not want to be stuck reading manuals when you need to be reading maps.

Our Review

It is no secret that electric dehumidifiers offer incomparable performance. These dehumidifiers come with an internalized pump that works on energy and provide functionality that works better than a number of other devices. This dehumidifier makes it the best of the best, earning it a position in this list.

What we love about this dehumidifier is its power outage restart feature. This allows the device to restore the programmed settings once the device is restarted after a power outage. So no need to worry about programming your device over and over again. This is what we call convenience!

The most striking feature, however, of this device is its internal pump. This allows a hose drainage mode as well as a bucket approach, putting you at the liberty of choosing between the two to suit your needs. So, let it drain through the hose, or let the bucket fill.

Bottom Line

Electric dehumidifiers do have an edge over the other types of dehumidifiers, and this specific model has an edge over all other electric dehumidifiers that you might come across. From its high efficacy to its power outage restart function, everything about this dehumidifier is designed to impress you.

  • The base of the screw is plastic and easily breakable, and it is also attached to the machine and therefore .requires the whole unit to be replaced instead of being fixed.

Our Review

hOmeLabs is one of the known brands when it comes to dehumidifiers, so a model from this brand is expected to feature nothing but the best. And that is exactly what this 30-pint dehumidifier delivers. Don’t let the unit's tiny size fool you as it functions as efficiently as any other larger sized device.

Best RV Desiccant Dehumidifier:
Eva-Dry E-333

New and Improved Eva-dry E-333 Renewable Mini Dehumidifier

PROS

  • Efficiently removes moisture from the air without consuming much energy.
  • The device comes with a 5-year warranty to guarantee customer satisfaction.
  • The silica gel is renewable and can be used again for multiple cycles instead of being replaced.

CONS

  • The device heats up upon operation which may cause the functioning of the unit to decline.
  • Silica gel is not as efficient for even slightly larger spaces, and its functioning may be greatly impaired if not used in closed spaces.

Our Review

Being a desiccant dehumidifier is what sets this unit apart from all the others in this list right off the bat. But that has no impact on its functioning. This desiccant dehumidifier works just as well at removing moisture from the air.

Silica gel is known to work efficiently at absorbing moisture from the surrounding air, and this device makes good use from this property of silica gel, using it to decrease the level of humidity in the room. The desiccant dehumidifiers are best at working in small and closed spaces about 333 cubic feet, making this the ideal dehumidifier for an RV.

The unit features a crystal indicator instead of actual lights of LEDs which turn from orange to green when the desired level of humidity has been reached. Furthermore, the device is renewable and can be “charged’ to be used over and over without having to replace the silica gel.

Bottom Line

A desiccant dehumidifier is a good choice for all those that look to cut down on their energy consumption. Even though it uses a lesser amount of energy, it provides the same outstanding functioning that will keep your RV at acceptable levels of humidity.

Types of RV Dehumidifiers

Dehumidifiers are mainly of three kinds, but only two of them are suitable for use in RVs. This is because compressor-based dehumidifiers are too big and too noisy to be appropriate for use in an enclosed space like a vehicle. The other two types of dehumidifiers are absolutely perfect for use in an RV.

Thermo-Electric Dehumidifier

As the name suggests, this device uses a thermo-electric system that sucks the excessive moisture out from the air in the room. What really makes this ideal for use in an RV is their smaller size which doesn’t occupy much space and also proves to be easy to move around. The small size has no effect on the efficiency, however, and they are perfectly capable of eliminating just as much moisture from the air as any other device.

Desiccant Dehumidifier

A desiccant dehumidifier is similar to the thermo-electric in terms of its size and efficiency. It is compact and highly functional, putting it on par with all other dehumidifiers. What’s different between these dehumidifiers and the thermo-electric ones is their mode of functioning. These units use a moisture absorbing substance that absorbs the excessive water vapors from the air and decreases the level of humidity.

Conclusion

An RV is a second home that is constantly on the move, and given all the activities that go on inside this closed space makes it extremely prone to excessive humidity. If not dealt with properly with a good dehumidifier, this may affect not only your breathing but also the structure of your vehicle. So save yourself from a number of future expenses and invest in a good RV dehumidifier that'll help you in the longer run.
