Choosing the Best RV Dehumidifier

Below are some of the things that should be carefully considered as you try to evaluate the options that are available in the market.

1. What Type Suits Your Needs?

One of the first things that you should do is to determine the type that is suited to your needs. Most of the options, especially those that are used at home, are refrigerant dehumidifiers. It works by condensing moisture from the air.

The second type is known as a desiccant dehumidifier. In this case, there is a water-absorbent desiccant where the air passes through after being pushed by a rotor. They are smaller in size and will work only if you need to take out moisture in a specific part of the RV and not for the entire motorhome.

2. What Size Do You Need?

There are different factors that will have an impact on the size of the dehumidifier. Think about the size of your RV, which will help to determine the right size of the dehumidifier that you will choose. If the RV is bigger, this obviously means that you will also need an appliance that is larger to be efficient in taking out moisture from the air.

When it comes to size, aside from taking a look at the physical dimensions of the product, you should also think about the size of the tank. For an RV, up to 30-pint capacity will be good. With this, it will take a long time before there is a need to empty the tank of the dehumidifier.

3. What Features Does the Dehumidifier Have?


Among others, you should look for features that will ensure the safe operation of the dehumidifier. One of the most important is to have an automatic shutoff, which will prevent overheating. To add, there should also be a feature to prevent tilting, which will make it stable.

There should also be a feature that will automatically detect the level of humidity in the RV. Most products have a digital display, which will show you this information. It will also allow the unit to turn off on its own once the optimal level is reached. This is good because it will minimize energy consumption.

Having adjustable louvers can also be great. This will allow you to have complete control, making it possible to direct airflow.

Another good feature to have is a blinking light or LED notification. This will let you know in an instant if the tank is already full and if there is a need to have it emptied. It will be a good way to prevent mess and to ensure the optimal functionality of the dehumidifier.

For portability, it would be great if the dehumidifier came with handles and wheels, making it easy to move. Nonetheless, because an RV is quite small, this is not much of a concern.

4. What about the Noise?

Another thing that you should look at is the level of sound that is produced by the dehumidifier as it operates. This technical specification is expressed as dB or decibel. The higher the number, the louder the dehumidifier is. This can be a significant disruption, especially if you are sleeping in your RV. Some have innovative technologies that allow them to deliver whisper-quiet operations. You can barely notice that the dehumidifier is there.

5. What is the Warranty?

For your peace of mind, look for a product that comes with extensive warranty coverage. The standard is one year. Others are offering more than one year if they are really confident of the quality and functionality of their product. Within the warranty duration, they will provide free repair and replacement of parts if the product proves to be defective in any way.

There are also some products with a money-back guarantee, usually for a period of 30 days. This means that within a month, if you are unhappy in any way with the performance of the product, you can return it to the manufacturer, and they will issue an unconditional refund.
