Why need a dehumidifier for your RV CAR?

There are many reasons why one might need the best dehumidifier for RV. Some of those reasons are down below.

Mold & Mildew Prevention

Have you seen mold in your RV lately? This could be because of the high humidity because high humidity can give mold shelter and help it flourish. A dehumidifier can reduce the moisture of the RV. As a result, it also stops the growth of mold and mildew.

Keeps Electronics Safe

People who live in their RV full-time have a ton of electronics lying around in the RV. And one of the most significant disadvantages of humidity is that it causes corrosion. As electronic items have tons of metal, humidity can ruin them. So, if you have electronics in your Rv, then getting a dehumidifier is the perfect decision.

Reduces Breathing Problem

Numerous people have breathing problems that can be triggered by high humidity. High humidity can worsen if you already have a breathing problem. By installing a dehumidifier, you can reduce the chances of worsening breathing problems.

Protects RV’s Interior

Humidity not only corrodes metal, but it can also ruin wood and chip paint. So, if you have wooden furniture or paint on the RV’s ceiling, high humidity can be detrimental. By getting a dehumidifier, you can protect the interior of your RV as well.

Keeps Food Fresh

Living in an RV full-time indicates that you keep food in the vehicle as well. But if you want to keep that food fresh and prevent it from rotting, then getting a dehumidifier is the perfect solution.

When do you need a dehumidifier for your RV CAR?

Dehumidifier for your RV CARNow you know why you should get a dehumidifier. But, do you know when to get it? According to many experts, the most suitable humidity to have in your house, office, or RV is around 35 to 50%. A little bit higher than that, and the metal will start corroding.

But how do you know if the humidity in your RV is high before getting the best RV dehumidifier?


You can get a separate hygrometer and place it in your RV. This tool helps to tell you the humidity of your RV. And if the humidity is higher than 50%, it is your indicator to buy the RV dehumidifier.

Google Weather

Google weather is an excellent free tool to know the humidity in your city. However, if the high humidity source is within the RV, this tool will not help you.

Signs of High Humidity

If you cannot use both of the tips given above, look for high humidity signs. For example,

  • Foggy windows
  • Musty smell
  • Allergies
  • Visible mold

If one or all of these signs are present in your RV, maybe the humidity is higher than usual.

How to choose the best dehumidifier for your RV CAR?

If you want to choose the best dehumidifier for your RV then look for the following features in the product.

Your RV Size

When buying a dehumidifier for your RV, the size of your RV matters the most. Because if the dehumidifier is too small, it won’t extract high amounts of moisture from the Rv. On the other hand, if the dehumidifier is too big, it will work excellently. However, you will not be able to fit it in your vehicle.

The good news for you is that dehumidifiers explicitly designed for RVs are smaller and more compact in size than conventional dehumidifiers.

However, not all sizes of RVs need the same amount of dehumidifiers. The following is a simple table showing how many dehumidifiers you would need based on your RV size.

RV TypeRV SizeNumbers of RV Dehumidifiers
Class A33 feet2 to 3
Class B20 feet1 to 2
Class C28 feet1 to 2
5th Wheeler Trailer32 to 36 feet2 to 3
Travel Trailer20 to 30 feet1 to 2

Compact Dehumidifier for RV

Compact dehumidifiers for RVs are those who are not only smaller in size but also lightweight and easy to fit in narrow spaces. Before buying a dehumidifier, check its dimensions to ensure a perfect fit.

Noise Level

Most of the time, RVs are small. And if you are living in it full time or for a more extended period, then even one noisy appliance can ruin the ambiance. This is why, in my opinion, the best dehumidifiers for RV are ones that feature low noise operation. You can determine if a dehumidifier is quiet or not by looking at its decibel rating. A dehumidifier with 50 decibels or below rating is quiet and works noiselessly.

Smart Setting

One of the most essential features in a dehumidifier for RV is smart features. Smart features are automatic features that make your life easier and your dehumidifier convenient. When buying a dehumidifier, look for the smart features mentioned down below:


Just as the name suggests, a timer allows you to set the time to turn on or off your dehumidifier automatically. Most dehumidifiers with timers will enable you to set time within 24 hours.

Automatic Turn-Off

If the humidity in your RV is extremely high, then the dehumidifier water tank would not take long to fill up completely. And if your RV dehumidifier lacks continuous drain features, it can also lead to overflow.

However, an automatic turn-off feature can save you from that. RV dehumidifiers that feature automatic turn-off turn off when the water tank is filled. And hence it keeps your RV’s interior from getting ruined by the water.

Comfort Mode

Some RV dehumidifiers offer comfort mode. Usually, comfort mode changed the humidity setting of the dehumidifier to 50-55%. This feature is convenient because you should not set the humidity level manually.
