Using a Dehumidifier In A Camper

RV living is one of the most rewarding lifestyles you can live. But, sometimes, it can come with its own unique challenges. One of these challenges involves managing the humidity inside your camper.

An RV is an investment, and not controlling the moisture and humidity can lead to costly repairs and health concerns inside your home. In this comprehensive guide, I will discuss the importance of dehumidifiers, when and how to use them, and which models are the best on the market.

What is the Best RV Dehumidifier?

The Best dehumidifier on the market for RVs is the hOmelabs 4500. This is an absolute powerhouse of a dehumidifier and can remove an impressive 50 pints of moisture a day. This dehumidifier costs around $260 on amazon.

If the hOmelabs is out of your price range, the Tenergy Sorbi unit is a great option. This option cannot remove as much moisture in the air as the hOmelabs unit, so multiple units may be needed. The Tenergy Sorbi costs around $90 on Amazon.

• Best overall: hOmelabs 4500
• Best Large capacity: Yaufey 120 pint
• Best Dehumidifier and Air Purifier in one: Tenergy Sorbi
• Best For Small Rooms: Pro Breeze
• Best Quiet: Tabyik
• Best Wireless: Eva-Dry-E 333
• Best Moisture Absorber: Damprid

Note: Purchasing a dehumidifier that cannot remove enough moisture in a day may result in continued condensation, mold, mildew, and moisture damage. Select a unit that can handle the amount of moisture you have or purchase multiple units.

What is an RV Dehumidifier?

An RV dehumidifier is a compact appliance designed to pull moisture out of the air and collect it in a reservoir. Dehumidifiers for RVs are smaller and usually have reservoirs instead of drain pipes. These smaller dehumidifiers tend to take up less space and energy.

A dehumidifier is a front-line defense for reducing moist air and condensation. Without a dehumidifier, your RV is at risk of developing growth of mold and damaging moisture damage. Mold growth can contribute to worsening health conditions.

Why do you need an RV Dehumidifier?

Protecting building materials, furniture, fabrics, and electronics from moisture damage.

Excess humidity can cause damage to the inside of your RV. High humidity can contribute to wood rot that may require removal and replacement. In addition to the building materials being damaged, moisture and mold can get into furniture, fabrics, and electronics, causing damage that may require replacement.

Protecting the items inside your RV from moisture-related damage can make things last a lot longer. Moisture tends to degrade items and make them unusable.

Improving air quality and comfort.

Maintaining the ideal humidity level between 30% and 50% is crucial for a comfortable living environment. Humidity levels that are too high can cause mold and mildew to spread throughout your RV. Mold and mildew can harm air quality and cause respiratory issues and discomfort.

Preventing condensation.

When an RV has high humidity levels, condensation can collect on windows, walls, and other surfaces. This moisture can sit in corners and drip down surfaces, causing damage and contributing to mold and mildew.

When do you need a dehumidifier?

A dehumidifier is necessary whenever you have evidence of high humidity in your RV. Some of the ways this evidence can present itself is as mold under the mattress, condensation on the windows, or the smell of mildew. Too much humidity can cause water damage.

What are the preferred humidity levels?

The ideal humidity range for an RV is between 30% and 50%. This humidity range is recommended for a healthy and comfortable environment.

What environmental factors can affect humidity?

Environmental factors like weather conditions, rain, and proximity to bodies of water can impact humidity levels inside your RV.

What man-made factors can affect humidity?

Cooking, showering, and other activities that introduce moisture into the air can elevate humidity levels in your camper. Additionally, using a propane furnace in cold weather can contribute to higher humidity levels in the RV.

How can you measure humidity?

A hygrometer is an inexpensive and easy device used to measure humidity. Hygrometers can be purchased as a stand alone sensor, or they can be one of many sensors in a weather station. Weather stations are devices that allow in-depth monitoring of your RV and immediate area.

Factors for choosing the best dehumidifier for your RV

Size and capacity

Consider the size of your RV and choose a dehumidifier with the ability to cover the square feet or cubic feet you need. Most dehumidifiers will be rated for the square footage they are effective within. Also, consider the size of the dehumidifier and ensure you get a size that can fit in the area you need it to. A portable dehumidifier is usually preferred for RVs.

Moisture Removal Rate

Every dehumidifier has a limited amount of moisture it can remove in a day. A lot of RVers make the mistake of buying a small dehumidifier that cannot remove the amount of moisture they accumulate in a 24-hour period. This will result in continued moisture problems. 

Do not make this mistake, because you will end up spending more money by either having to replace the unit with a bigger one or buying additional units to handle the moisture.

Humidity levels

Some humidifiers have adjustable settings that allow you to maintain your desired humidity in the RV. These controls all you to adjust the settings depending on your comfort level.

Power Supply

Choose between electric and non-electric dehumidifiers based on your power source availability and preferences. If you will be boondocking, you may be unable to run and electric dehumidifier.

Cost

There are dehumidifiers in many different price ranges. Factor in your budget when selecting a dehumidifier. Dehumidifiers are important, and if you need a more expensive unit to fulfill your needs, try to prioritize this within your budget.

Climate and Location

Different climates will have a different effect on the humidity levels in your RV. You may not need a dehumidifier in a desert climate but one in the rainy Pacific Northwest. Ensure the dehumidifier you select can handle the amount of moisture you need it to.

Drainage options

Look for dehumidifiers with convenient drainage options. If you have a dehumidifier with a built-in reservoir, you want to ensure it is big enough so you don’t have to dump it multiple times daily. Some people opt for dehumidifiers to which they can attach a drain hose so they never have to dump it.

Noise

Some dehumidifiers can be noisy. If noise bothers you, choose a dehumidifier with a low decibel level. Alternatively, some people enjoy the background noise, so they will purchase a dehumidifier that provides soothing background noise.

Air purifying

Some dehumidifiers come with additional air-purifying features. Adding a dehumidifier with an air purifier is an excellent choice for many. An air purifier can minimize odors and respiratory irritants like dust and mold. This is a great option for anyone with allergies or respiratory conditions.
