The newly created temperature difference is what results in dehumidification. It means that this is a perfect method for dehumidifying the RV because there is no need for a motor, pumps, fluid, oils or gases.

These thermoelectric dehumidifiers only work in small spaces because of a lack of compressor. It’s also no exception.

It’s made for spaces of 100 square feet or less, so you’ll most likely need at least two if your RV is longer than 20 feet.

There is no requirement of a whole lot of absorption ability for RVers who live in a hot and humid climate.

So, it can be considered to be a better dehumidifier solution for part-time RVers on those that don’t live in locations with super high relative humidity.

What Are The Important Features Need To Consider While Choosing An RV Dehumidifier?

Perhaps you understood that there are several types of dehumidifiers available in the market. Whenever you have decided in your mind to purchase the best RV dehumidifier then you should follow some of the factors.

The best dehumidifier has lots of varieties. Moreover, you should also know about the locations and your preferences.

Now, you will not purchase an RV dehumidifier every year. That is why you need to follow the buying guide. In this buying guide, we are going to provide you with all types of details. Follow it.

How to Choose the Correct Dehumidifier Size For Your RV?

Whenever you are going to purchase an RV, you need to follow the correct size for it. We know that space becomes limited for RVs. That is why it is essential to look into space as soon as possible.

Everything needs to have its place and it’s really important to establish daily habits that help you keep your space organized.

When it comes to a dehumidifier, it helps to select a unit that you won’t be constantly tripping over as you move around your RV.

In simple terms, the smaller your RV, the smaller dehumidifying unit you should look for.

For those in larger RVs, you’ll probably get away with having a larger unit because you have more space.

Energy usage

Another important factor is energy usage. It is directly linked to the use of RVs. It doesn’t matter how many devices or appliances you have plugged in.

If you add a dehumidifier to everything to the RV battery, powering requires careful consideration.

You need to be careful not to load your battery and drain it out too far before you get the chance to recharge the battery.

This is the reason why dehumidifiers allow the user to set a 24-hour cycle and it can be beneficial.

The humidity changes with the course of the day. Depending upon the humidity level, you can program your unit to work less or more.

While doing so, the user can easily be able to reduce the overall energy usage and also keep the RV batteries sufficiently charged.

What Is The Right Size Dehumidifier Do I Require For The Camper?

Depending upon the size of your RV, you have to set the capacity. It has been noticed that the largest RV which is almost 45 to 50 feet, typically has a maximum square footage of around 400 feet. So, even the owners of the large RVs might find that a dehumidifier rated for a 1500 Square foot home is overkill.

You should start by measuring the square footage of your RV. This will help you to give a solid number for the comparison against the amount the space that the dehumidifier has given.

However, you also need to consider the environment in which you are living. A location with an average relative humidity of 95% will require a higher-performing dehumidifier than a location with an average relative humidity of only 50%.

Auto Settings

If the product comes with the ability to set and forget, then it can be considered to be a great bonus for the customers. We are not saying that it is difficult to monitor and maintain the dehumidifier but at the same time, you must look after the auto setting options.

If you have other things to worry about then make sure to choose a dehumidifier with an automatic setting. If it is done then there is no need to spend your valuable time and energy monitoring it.

Ease Of Installation

It is fortunate for us that most of the best dehumidifiers fit into the plug-play and variety.

Once you’ve identified a place for it and made sure there’s a plug nearby (for electric models), you can easily plug it in, dial in your settings, and let it work.

Some models, however, do come with a drain hose outlet. While this is an optional feature, there can be long-term benefits to spending extra installation time to set up a drain hose.

This will eliminate the need to regularly empty the water tank when it’s full.

It will also eliminate the possibility of the unit shutting off for multiple hours if you’re away and the water tank fills.

Noise Output

Noise output is another feature of looking to purchase a dehumidifier. If you find difficulty in sleeping or hearing your favorite show then installing a dehumidifier will be the best solution for you. It will help in increasing the white noise in your RV.

Combined with the refrigerator, water heater, and other ambient noise coming through your RV’s thin walls, it’s important to make sure the dehumidifier you choose isn’t going to turn into an annoying nuisance.

Fortunately, there are several super quiet dehumidifiers that you’ll hardly notice when they’re doing their job.

Even if you need to purchase a larger model that makes more noise, you’ll often be able to program it to turn off for several hours at night so that you can hear your shows and fall asleep easily.

Which Is The Best Dehumidifier For An RV?

To boil it all down, your final choice should depend on the size of your RV, the location where you’ll primarily be living, and your desired comfort level.

If you’ve already spent an incredibly uncomfortable summer sweltering in your RV, you might not hesitate to go for a dehumidifier that’s rated for a larger space than you have in your RV.

Do some research on average relative humidity levels in your area. Assess how much energy you’re already using to power your current appliances and devices.

Consider what it feels like to truly feel comfortable in your RV during the hotter months of the year.

Once you gather this personal information, you’ll be much better suited to compare dehumidifiers to your criteria to select a model that’s right for you.

Frequently Asked Questions

Which relative humidity is best for setting in my dehumidifier?

Answer: This is a question of personal preference. It is better to suggest programming of relative humidity settings between 30 and 50%. This, of course, is only possible with a dehumidifier that has a smart humidistat function.

Is it possible to drain out the dehumidifier into the RVs grey water tank?

Answer: All the manufacturers of dehumidifiers recommend not to empty water from the dehumidifier into RVs grey water tanks. The work of a dehumidifier is to pull harmful bacteria from the air and water.

Some of the bacteria cause problems with your RVs internal tanks. So, the best method is to water the grass or plants outside the RV.

Which is the best location for a dehumidifier?

Answer: The best location for a dehumidifier depends on the size and layout of the RV. However, it is best to set the dehumidifier in the living room as well as in the bedroom. These are the two places where we spend our time mostly.

How can I tell if there is a need for a dehumidifier?

Answer: The first warning sign is discomfort. Maybe it feels like constant dampness on your skin or maybe it feels like not being able to fall asleep at night because you’re still sweating even though you’re lying absolutely still.

Furthermore, if you begin to smell dampness or mold when inside your RV, it’s definitely time to invest in a dehumidifier.

Is it okay to allow a dehumidifier to run constantly?

Answer: Dehumidifiers are specifically designed to be able to run on 24-hour cycles and are safe to leave on overnight.

However, caution should be exercised with any electronic appliance.

Always be careful to thoroughly review the owner’s manual to make sure you don’t overtax your dehumidifier and cause it to overheat.

What is the function of a dehumidifier?

Answer: The main function of the dehumidifier is to absorb the moisture from the air. Dehumidifiers are helpful if the user lives in a hot and humid climate. The moisture in the air can cause mold and dust mites in the home. That is why the dehumidifier absorbs moisture.

What are the disadvantages of dehumidifiers?

Answer: Dehumidifiers also tend to blow warm air out of the back of the unit. In the winter, this can be an advantage — but not so much in the summer. Position the back of your dehumidifier in a doorway so that it doesn’t heat up the room from which you are removing excess moisture.

Final Thoughts
