If you’re like me, you hate humidity. It’s the worst thing ever. It’s hot and sticky, and makes it impossible to sleep at night. And if you’re an RV owner, humidity is your worst enemy.

Because even though RVs come with air conditioning, that AC can only do so much against the moisture in the air. So what can you do to keep humidity from ruining your RV trips? Dehumidify!

That’s why we’ve put together this list of the best RV dehumidifiers on the market right now. So whether you’re looking for something small and compact, or something that can handle a large space, we’ve got you covered.

Best RV Dehumidifiers Available – A Quick Glance

What Is An RV Dehumidifier And What Does It Do?

An RV dehumidifier is a device used to remove moisture from the air inside your recreational vehicle. Moisture can cause all sorts of problems inside the RV, such as musty odors, water on windows and walls, and even mold and mildew growth.

How Do Dehumidifiers Work?

• Dehumidifiers work by pulling in moist air from the room and passing it over cold evaporator coils.
• This causes the water vapor in the air to condense onto the coil, where it is then collected in a pan or bucket.
• The now-dry air is blown back into the room, reducing the overall humidity levels inside your RV.

There are two main kinds of RV dehumidifiers: those that need to be vented to the outside and those that can operate without venting.

• Vented dehumidifiers are the most effective at removing moisture, but they also require a hole cut in your RV’s exterior so that the humid air can be vented outside of your RV.
• Non-vented dehumidifiers are not quite as effective, but they are much easier to install and don’t require any modifications to your RV.

No matter which dehumidifier you choose, it will need to be emptied regularly to continue working properly. Most models have a built-in indicator that lets you know when the unit needs to be emptied.

Why Do You Need A Dehumidifier For Your RV?

Here are just a few of the benefits that come with doing so –

Condensation Control

 When there’s too much humidity in the air, it can lead to condensation on surfaces like windows and mirrors.

This not only makes your RV look wet and unpleasant, but it can also lead to things like water stains and rust.

Odor Reduction

 If your RV has been closed up for a while, chances are it’s started to develop a bit of a musty smell.

This is because mold and mildew growth causes musty smells, both of which thrive in humid environments.

Mold and Mildew Prevention

In addition to reducing musty odors, a dehumidifier can also help prevent mold and mildew growth. As we mentioned before, mold and mildew love humid environments.

So by keeping the humidity levels low in your RV with a dehumidifier, you can help discourage mold and mildew growth. Not only will this keep the RV smelling fresh and clean, but it will also help to extend its lifespan. 

There are a few different RV dehumidifiers in the market, so choosing the right one is important.

3. Desiccant Dehumidifier

• A desiccant dehumidifier uses a drying agent, or “desiccant,” to remove moisture from the air.

• Desiccant dehumidifiers are very effective at removing humidity from the air, but they can be expensive to purchase and operate.

5. Refrigerant Dehumidifiers 

• Mechanical compressors or refrigerant dehumidifiers are the most common type of dehumidifier. They work by drawing air into the unit and cooling coils below the dew point.
• This causes water vapor to condense on the coils, and they then collect the water in a tank within the unit.
• These units are relatively noisy, so if noise levels concern you, this may not be the best option. However, they are very effective at removing moisture, making them a good choice for humid climates. 

6. Thermoelectric Dehumidifiers 

• Thermoelectric dehumidifiers use electricity to create a temperature difference between two sets of coils within the unit.

• Thermoelectric dehumidifiers are silent and energy-efficient, making them a good choice if noise levels and power consumption concern you.
• However, mechanical compressor units are not as effective at removing moisture from the air. 

7. Solar Dehumidifiers

How To Find The Best RV Dehumidifiers?

If you have a small RV, a smaller unit may be all you need. However, if you have a larger vehicle, then you may need a bigger unit to cover an entire RV.

After all, you want to spend only a little time fiddling with settings whenever you want to turn on your dehumidifier.

Not only will an energy-efficient dehumidifier save you money on your electric bill, but it will also help reduce your carbon footprint.
