How We Picked


When shopping around for a good RV dehumidifier for your recreational vehicle, you should consider certain factors so that you can make a better decision later. In the following, we’ve highlighted some of the things to look into when comparing your choices. So before you choose from one of the products we’ve reviewed above, keep reading to help you pick better.

How big is the space to dehumidify?

Before shopping around for a dehumidifier for your vehicle, think about the space you’re actually planning to use it to get rid of condensation and dampness in your RV. How big or how small is it? Determining where you actually plan to use the device, you can figure out the capacity of the device that you have to consider.

When checking for capacity, you might want to look into the pint capacity, which is the moisture amount the device can remove from the air within one day. In this case, you might want to consider a unit that you can really use to dehumidify the space you want it to work on, ensuring it can deliver top efficiency and performance. Some of the choices you have include small or commercial dehumidifiers or a unit with capacity of 30 pint, 50 pint or 70 pint.


It is another crucial factor to check when buying an RV dehumidifier. If it is portable, it will be easy to take anywhere especially if you’re planning to use it in other places aside from in the RV. So if you’re planning to move it and operate it often in other places when you’re not camping with your RV, you should check for the portability of the unit.


When comparing your choices, you should also find an easy to install RV dehumidifier if you don’t want to have a hard time to start using it out of the box. You should look for one that will not take much of your time when setting it up so that you can start using it right away.

Noise Level

In addition to the above features, you should look for a device that won’t become a nuisance due to noisy operation. Noise level when operating is one of those to affect your buying decision. It is one of the things to check when weighing your options. In this case, you must check the noise amount that the device is producing when it starts running. The best way to check on that is to see the decibel rating in its technical specification label or sheet.

If the device is rated with a higher dB, it is noisier than its counterparts are. It also means that it is producing more sound. You should stay away from those devices. Instead, you should choose one that offers a minimal operating noise.

Otherwise, its noise will be disruptive for everyone in the RV especially at night. If possible, you should also go for those with an advanced technology that can promote a quiet operation.


It is another important factor when trying to compare your options. This capacity refers to the water amount that the dehumidifier can hold. So if you’re planning to use it for a short period of time when camping, you might want to go for a smaller unit that has a lower capacity. But if you are having a camping trip that can last for more than a week, you might want to choose a dehumidifier that offers a larger capacity that is able to hold more moisture than its counterparts can.


Ease of operation and simplicity, you should also be looking for these factors when buying a dehumidifier. You should be able to compare different models also based on the controls they have. For example, you should check that the controls are user-friendly even if going for digitally controlled models.

In addition, you might want to check that its controls can let you adjust humidity levels based on your needs. Some of these units can offer just dry or very dry humidity levels. In short, you should pick one that can be adjusted based on the percentage of humidity for which you want the unit to work.

Comparing your options based on the controls will also give you ease of use when it comes to adjusting the settings. For example, the unit should also be able to handle moderate preference, such as lower humidity or slightly lower humidity.


When shopping around for the right dehumidifier, you must also look for the functions that it offers. You might want to see the integrated features in the model that you want to buy. For example, you might want to choose one that comes with a humidistat, which works smartly when it comes to measuring humidity level. It is also the ideal feature that works by switching off automatically when the humidity reaches it ideal level.

Some of the units to find also have laundry settings. It works by helping you dry clothes faster when it is operating continuously. In addition, a timer can be another feature to look for if you want a device that can work based on your preset time period.

When checking on the features, you should also realistically find out what you really want to get from the device so that you will know what other things you want it to have.
