Pro Breeze Electric Dehumidifier

Buy from Amazon

The Pro Breeze Electric Dehumidifier is both compact and highly energy-efficient, making it a great dehumidifier for your RV. Capable of removing up to nine ounces of water from your trailer’s air per day, it’s designed to be used in RV’s with a floor area of up to 150 square feet.

Drawing just 2.5 Amps, it’s a good choice for use when you’re on the road, as well as keeping your RV moisture and odor-free during periods in storage. However, note that it only works effectively above temperatures of 59 degrees F and not at all below 41 degrees F. So if you are looking for a dehumidifier for your RV in storage in a cold winter climate, you’ll need to take a look at some of our other RV dehumidifier reviews.

Portable and lightweight, this model weighs just 2.4 pounds. Measuring 7” long by 6” wide, it has a height of 11”, compact enough for multiple locations in your trailer. Thanks to its relatively large 16-ounce water tank, this unit shouldn’t require very frequent emptying. When it is full, it automatically shuts off and an LED alerts you to empty the tank.

Very easy to use and highly effective in small, damp, warm spaces, this compact dehumidifier represents good value for money. While there are similar cheaper models on the market, this version comes complete with a 12-month warranty for your peace of mind and testament to its build quality.

Pros – Things we liked

Can remove 9oz of water a day

Eva-Dry Wireless Mini Dehumidifier

Buy from Amazon

Designed to keep small enclosed spaces up to 333 cubic feet free from excess moisture, the Eva-Dry Wireless Mini Dehumidifier is a viable alternative to your regular disposable mini humidifiers for campers and closets. As it is rechargeable, it is also more eco-friendly, while the entire unit is non-toxic and pet and child-safe.

Capable of absorbing between four to six ounces of water over 20-30 days, the Eva-Dry Wireless Mini Dehumidifier could be a good choice for your RV closets or small campers. When the unit has reached its maximum absorbancy capacity, the silica beads change color from green to orange, indicating that it’s time to plug in the unit for a recharge.

Bear in mind that to dry out the beads for reuse, you will need a power source away from your RV, or else you will simply release the moisture removed back into it, defeating the purpose completely. You could plug it directly into your generator to recharge outside to recharge.

Realistically, this mini humidifier is only really suitable for removing excess moisture in closet-sized enclosed spaces. If you have your camper sat idle on your drive, it could help keep it fresh, provided you don’t have a serious excess moisture problem. It could also be an option for larger RVs with climate control that also dehumidifies, but still need a small dehumidifier to keep closed cabinets and closets moisture-free.

Relatively inexpensive and complete with a five-year warranty, if this model suits your circ*mstances and needs, it makes a great choice.

Camco Fragrance-Free Miniature Dehumidifier

Buy from Amazon

This Miniature Dehumidifier from RV specialists Camco is a really handy, cost-effective solution to prevent humidity build-up in small spaces. Ideal for keeping your camper fresh during winter storage, or use several throughout your larger travel trailer, this model uses calcium chlorate as the active moisture absorbent.

Highly portable and extremely compact, this mini dehumidifier for campers measures just 4.75” long by 5.88” wide, with a height of 3.31 inches. Place them in your closets, shower room, wherever you need to tackle excess humidity. They are silent and weigh next to nothing at just 8.1 ounces.

Obviously, these miniature dehumidifiers are not going to adequately tackle large rigs with excessive moisture problems. They will likely struggle to absorb enough moisture when you are actively using your trailer. Also, bear in mind that they will need regularly replacing – lasting between 1-6 months depending on the environment in which they are placed.

Inexpensive, completely silent, and requiring no power source, we think every RV owner who puts their rig into storage can definitely benefit from using a couple of these to keep moisture levels down. For when you’re RVing or if you keep your RV in an especially humid climate, you’ll want to look at our other RV dehumidifier solutions.

Suitable for even the very largest of RVs, it can reduce moisture levels in indoor spaces up to an impressive 1,500 square feet.

Buyer’s Guide to Buying the Best RV Dehumidifier

Find out how to choose the best dehumidifier for your RV right here in our buyer’s guide, we’ll take a closer look at all of the important features that you’ll need to consider when making your purchase.

Price

As you’d expect, dehumidifiers that cover a larger area and pull out more moisture per day cost more than less effective models. So, before you start to set your budget for your RV dehumidifier, it’s important to consider how much moisture you’ll need to remove and your RV size.

For large RVs located in high humidity areas, such as Florida, Louisiana, or Iowa, for example, you’ll need to spend significantly more on a high performance model. For small RVs, such as campers and small travel trailers, located in areas with lower humidity levels, you can spend much less and still reduce your moisture levels to prevent damage and odors.

In terms of price, you’ll have to assess your needs, then budget in for any extra features that may bump your price up. For small moisture absorbers, expect to pay around $10. If you have a small RV with a slight moisture problem, you can pick up a standard small dehumidifier for $30.

Add on extra features and you’re looking at between $50-$80, going up to around $100-$150 for RV with a large floor space or a significant moisture problem.

Energy Usage & Power Source

As always, you’ll want to keep an eye on how much energy your dehumidifier uses as well as its power source.

For storing small RVs in winter without a power supply, several moisture absorbers placed throughout your trailer can really help to prevent any moisture build up and associated odors.

For larger rigs or if you’re in a high humidity area, you’ll want to look out for a more powerful electric dehumidifier without a large power draw. Whether you frequently go off-grid or are always hooked up to shore power will affect your choice of RV dehumidifier.

Luckily, there is a great middle of the road selection that manages to combine good performance with a low electrical draw. Some compact versions draw just a couple of amps.

Alternatively, if you need high moisture removal levels, you’ll want to pick a more powerful model and stick to using it when you’re hooked up. You can always purchase an additional energy-free moisture absorber for when you’re off-grid.

Auto Settings

RV dehumidifiers with auto settings make it easy to save energy and keep your rig’s humidity levels within a preselected comfort zone. Simply switch on auto setting and your dehumidifier will switch on and off as needed to maintain your RH levels, usually at 50%. Some models allow you to adjust this level.

Without auto settings, your unit will operate on continuous mode. Whilst this can be useful for when you are visiting places with high humidity levels, generally, it’s best to opt for an auto setting to allow your dehumidifier to cycle on and off as needed, rather than having it run 24/7.

Noise Output

Dehumidifiers can be pretty noisy. Even the quiet ones can be enough to disturb RVers with sensitive hearing.

Compressor models make the most noise, so avoid these if you have over-sensitive hearing. For others, if you manage to sleep with your RV AC on, or are planning on using your dehumidifier when watching TV, showering, or cooking, the noise levels shouldn’t be that much of a problem for you.

Silent, non-electric models don’t work as effectively at drawing out moisture from the air, but you may want to consider using them in your sleeping quarters with another type of dehumidifier for your living space – if you have a large RV.

Extraction rate

The extraction rate is an important figure to bear in mind when comparing RV dehumidifiers.

Before you buy, make sure that the extraction rate is compatible with the conditions where your RV is used. High humidity areas will require a high extraction rate to reduce your RV’s relative humidity down to comfortable levels.

Another thing to bear in mind is that the extraction rates you are given are under ideal conditions, often at high temperatures with very high humidity levels in excess of 80%. In an average climate, you would not expect your dehumidifier to be exposed to these conditions each and every day, except if you RV in areas with very high humidity levels.

Portability – Size & Weight

With space at a premium inside your RV, you won’t want a bulky dehumidifier taking up precious floor space. If you need a high performance dehumidifier, opt for a model with wheels to make it easier to move out of the way when you need to.

While compact moisture absorbers will weigh next to nothing, it’s not unusual for large compressor models to weigh over 30 pounds. As with any RV equipment, make sure your model is the smallest size and lowest weight for the performance level that you need.

Features

Some RV dehumidifiers come with a range of features that may or may not be useful for your needs. Take a look at the following most common types.

Humidistat

Unless you are opting for moisture absorbers or a very basic dehumidifier for barely-there moisture issues, we recommend opting for a unit with a built-in humidistat.

Not only does this make it easy to quickly check just what level of relative humidity you’re at, it also allows you to set your desired level. This will save energy as your dehumidifier will cycle on and off to reach and then maintain that level, rather than staying on regardless.

Laundry setting

If you have to dry your dry inside your RV, you most definitely need a dehumidifier.

While a laundry setting will work well to help you to quickly dry your wet laundry, in reality, any model with a fast fan speed and a continuous setting will work exactly the same, so don’t go in for a model just because it has a so-called “laundry setting”.

In any case, all electric dehumidifiers will help your laundry to dry faster by blowing warm dry air.

Timer

A timer is a very useful feature, allowing you to set how long you’d like your dehumidifier to run for. If you’re going out for the day, for example, you can set it for several hours and save energy rather than having it run continuously. This is a good option to have if your model does not have a built-in humidistat.

Adjustable louvers

In order to dry out the air in your camper, your dehumidifier will need the moist air to pass through it before ejecting it as dry air. This can lead to quite a breeze especially if you have it running on a high-efficiency setting.

Adjustable louvers allow you to angle this airflow to avoid having your dehumidifier blow on you while you’re having lunch, or to better angle the airflow for improved drying in different parts of your RV.

Desiccant or Refrigerant

If you’re not going for simple moisture absorbers and are looking for a full-on dehumidifier for your RV, one of the most important questions you’ll need to ask yourself is should you get a desiccant or refrigerant dehumidifier for your trailer? To help you to decide, here are the main differences between the two types.

Desiccant RV humidifiers utilize an absorbent material to remove water from the air. The material is then heated to remove the water that then drips into the collection tank. As they don’t rely upon any difference in temperature to remove moisture they are suitable for use in unheated trailers. However, they also tend to have higher energy requirements than refrigerant versions.

Refrigerant dehumidifiers draw moist air in over cold coils. This causes the moisture to condense and drip into the water tank. As this type of dehumidifier needs the moist air to be warmer than its internal coils, refrigerant models are often less effective or unsuitable for use in very cold temperatures. They also tend to be much noisier than desiccant versions, but they are less expensive.

Tank Capacity

Smaller tanks will need emptying more frequently. If you are not going to be around to empty your tank on a daily basis, look out for models with a large capacity tank that equates to at least a couple of days at the maximum extraction rate.

If you are battling with high humidity levels in your RV on a permanent basis, you may want to look out for a dehumidifier that can be attached to a hose to provide you with a gravity-fed continuous drainage option.

This will allow your dehumidifier to remain in continuous operation rather than shutting down until you empty and the tank.

110 or 12 Volt Dehumidifier For Your RV

While a 12V dehumidifier sounds like a good idea for your RV, in practice, it’s best to opt for a regular 110V model, just like the rest of your appliances that run on regular AC power. 12V DC humidifiers are pretty rare, plus they also risk running down your battery.

As dehumidifiers tend to use a fair amount of electricity, if you are looking for a solution to keep moisture levels down over an unattended storage period, you would be better off using a moisture absorber non-powered variety.

Benefits of an RV Dehumidifier

Installing an RV dehumidifier has numerous benefits, including the following:

Eliminate musty odors – dehumidifiers remove moisture so you won’t get that telltale damp musty smell when you open up your RV door.

Dry soft furnishings and bedding – moist air can lead to damp soft furnishings, clothing, and bedding. Using an RV dehumidifier will keep your RV interior dry.

Feel more comfortable – reducing the moisture levels in your RV will make a big difference to how you feel, making it a more comfortable and relaxing environment.

Prevent mold formation – damp air inside your camper can quickly lead to mold growing on your ceiling and walls.

Improve your breathing – if you suffer from asthma or allergies, an RV dehumidifier can help you to breathe more comfortably, alleviating some of your symptoms.

Prevent RV deterioration – moisture buildup inside your RV can cause serious damage if left unchecked over a period of time. Installing a dehumidifier will allow your RV to fully dry out and halt any damage.

Ways to Reduce Humidity Inside an RV

If you are suffering from high humidity levels inside your RV, you’ll need to invest in a dehumidifier. Most moisture inside your RV comes from breathing, cooking, and washing all in a confined space.

Here are some extra tips on how to keep humidity levels down inside your trailer.

• Wipe down your shower room with a towel after use. This will remove water that would otherwise end up in your RV’s air moisture levels.
• Put your towels outside after use. Of course, if it’s raining, you’re going to struggle with this one, but if it’s nice out, make sure you remove your wet towel from your RV to dry before it joins the laundry queue.
• The same goes for laundry. Try to hang it outside whenever possible.
• Open your windows to encourage airflow and reduce your relative humidity level. That is unless you’ve got your dehumidifier running. Also, if humidity levels are really high out, you won’t want to encourage damp air to enter your living space.
• When cooking, especially boiling pans of water, always make sure you run your extraction hood, use lids, or better still cook al fresco.
• Improve air circulation in cabinets and closets. Every so often when you’ve got a nice dry day, periodically open up your cabinet doors to allow the air to renew itself and prevent moisture build up.

FAQ – Best RV Dehumidifier

As an RV enthusiast, you understand the importance of maintaining a comfortable and healthy environment inside your home on wheels. One common challenge faced by RV owners is excessive moisture, which can lead to issues like mold, mildew, and unpleasant odors. To help you make informed decisions and address this concern, we have compiled a list of frequently asked questions about the best RV dehumidifiers. In this section, we will provide answers to these questions, offering valuable insights into why you need a dehumidifier, what features to consider, and how to properly maintain it. Whether you’re a seasoned RV owner or new to the lifestyle, this FAQ section will serve as a helpful resource to ensure you choose the right dehumidifier for your RV and enjoy a comfortable and moisture-free journey.

Why do I need a dehumidifier for my RV?

RVs are prone to high humidity levels due to limited ventilation and the presence of moisture sources such as cooking, showering, and breathing. A dehumidifier helps reduce excess moisture, preventing mold, mildew, and musty odors. It also helps to maintain a more comfortable and healthy living environment inside your RV.

What features should I look for in an RV dehumidifier?

When choosing an RV dehumidifier, consider factors such as size, capacity, energy efficiency, noise level, and portability. Look for models with automatic humidity control, built-in timers, and easy-to-use controls. Consider the water removal capacity, the size of the water reservoir or drainage options, and the coverage area of the dehumidifier to ensure it meets your specific needs.

What is the optimal capacity for an RV dehumidifier?

The optimal capacity depends on the size and moisture levels in your RV. As a general guideline, a dehumidifier with a capacity of around 30 to 50 pints per day should be suitable for most RVs. However, if you frequently encounter high humidity or have a larger RV, you may want to consider a higher-capacity dehumidifier.

Are RV dehumidifiers energy-efficient?

Energy efficiency varies among different dehumidifier models. Look for dehumidifiers with an Energy Star certification, as they meet strict energy efficiency guidelines. Additionally, features like auto-shutoff and programmable timers can help conserve energy by operating the dehumidifier only when necessary.

How should I maintain my RV dehumidifier?

Regular maintenance is essential to ensure optimal performance of your RV dehumidifier. Clean or replace the air filters as recommended by the manufacturer to prevent clogs and maintain proper airflow. Empty the water reservoir regularly or set up a continuous drainage system if available. Keep the dehumidifier’s exterior clean and free from dust or debris.

Can I use a household dehumidifier in my RV?

While it’s possible to use a household dehumidifier in an RV, it’s generally not recommended. RV-specific dehumidifiers are designed to withstand the unique conditions of RV environments, such as vibrations, humidity fluctuations, and power limitations. They are often more compact, lightweight, and portable, making them more suitable for RV use.

Can I use a dehumidifier while my RV is in storage?

Yes, using a dehumidifier while your RV is in storage is highly recommended. Stagnant air and lack of ventilation can lead to excessive moisture buildup, which can cause damage and promote mold growth. A dehumidifier will help maintain optimal humidity levels and protect your RV from moisture-related issues during storage.

Can I run a dehumidifier while using other appliances in my RV?

Yes, you can run a dehumidifier alongside other appliances in your RV. However, keep in mind the power limitations of your RV. Ensure that the combined electrical load does not exceed the capacity of your RV’s electrical system to avoid tripping circuit breakers or overloading the system.

Are there any safety precautions I should follow when using an RV dehumidifier?

To ensure safe operation, always follow the manufacturer’s instructions and safety guidelines provided with your RV dehumidifier. Avoid blocking air intake or exhaust vents to maintain proper airflow. Place the dehumidifier on a stable surface and avoid tilting it excessively. Keep the dehumidifier away from water sources and flammable materials. If you have any specific safety concerns, consult the manufacturer or a qualified professional.

Remember to consult the specific product manuals and guidelines provided by the manufacturer of your chosen RV dehumidifier for detailed information on usage, maintenance, and safety precautions.

Final Thoughts

If your RV is uncomfortably humid inside, you need to get yourself the best RV dehumidifier. Prolonged high moisture levels create prime conditions for mites, mildew, and mold which can worsen allergies and respiratory problems. What’s more, high humidity levels have also been associated with increased concentrations of volatile organic compounds, as well as a general sense of fatigue and low energy levels.

To keep your small RV fresh on a budget, pick up a set of Damp Rid Moisture Absorbers. They don’t require any electricity and can be refilled after use to cut back on single-use plastic. Ideal for campers or trailers, if you dread that musty smell on your first trip of the season, these inexpensive moisture absorbers will help to keep your RV dry and clean smelling.

For small to medium RVs that have serious moisture problems, the Mid-Size Thermo-Electric Intelligent Dehumidifier by Ivation makes a good choice. It can remove up to 25 ounces of water from your RV air per day and comes with a built-in humidistat so you set your desired relative humidity level. Complete with a large water tank, it measures less than 14” high, so you’re sure to find a space for it in your small motorhome.

Big rigs, such as class As and fifth wheels in high humidity areas will benefit from the Midea Dehumidifier with Reusable Air Filter. This high-performance RV dehumidifier can remove up to an impressive 20 pints of water from your RV air per day. It also benefits from an LED hydrostat allowing you to select your desired humidity levels between 35% to 85%, plus a turbo mode, and auto shut-off.
