How To Choose The Best Dehumidifier For RV


How big is your RV? While you may not have considered measuring your vehicle before, it’s probably a good idea to do so before you purchase a dehumidifier.

There are two different ways you can choose to remove moisture from your car. You can choose to buy a big sized dehumidifying device that will be able to cover the whole RV. Or you can buy the best small dehumidifier models for a specific area, like washroom or kitchen which are more prone to condensation and as a result, promotes mold growth.

Depending on your need and preference, you can choose devices with a varying range including 30 pints, 50 pints and 70-pint capacity.


Nobody gets a six-month vacation, twice a year! Right?

Well, if that’s the case, then what are you going to do with the dehumidifier during the time you are not camping with your buddies?

Of course, it can be used in your home or stored somewhere safe aside from your RV. But for that, you will need a dehumidifier that is easy to carry and can be transported to other places.

Finding a device that is light-weighted or has wheels on the bottom are some qualities worth taking a look at when you are purchasing an RV dehumidifier.


A dehumidifier can hold a certain amount of water in a given time. You have to empty the water bucket once it’s full.

If you are planning a trip that might last longer than a few weeks, then you are better off with a device with a large capacity that can hold more water and doesn’t require you to empty the bucket frequently.

Dehumidifiers with small capacity are more suitable for shorter trips which typically lasts for a few days or so. A small-capacity device also consumes less power per unit time than the large capacity ones.


You can find dehumidifiers with 3 different technologies on the market. Depending on your travel destination and climate, you should choose a suitable one.

1. Refrigerant

A refrigerant dehumidifier uses a compressor to make vapor in the atmosphere turn into water and collects them in a tank. These devices are suitable for the warm climate. By removing extra moisture from the environment, they stop the growth of molds and mildews in your vehicle. They also have an energy-saving feature available to save your pocket.

2. Desiccant

If you happen to take a trip to Alaska or Michigan, the Refrigerant dehumidifier won’t be of much help in such a cold climate!

When the temperature drops below 10-Degree Celsius, it’s better to go for a Desiccant dehumidifier instead. With the help of an internal heater, it absorbs the excess water from your environment and lets you breathe easier.

3. Peltier Technology

The Thermo-Electric or Peltier Technology requires two conductor plates with different temperatures. With the help of electricity, it creates water droplets on the cooler plate and thus removes moisture from our surroundings.

Although they can’t remove moisture as fast as the other two types, they require less electricity and are smaller in size.

Noise Level

The sound of an average dehumidifier doesn’t usually bother anyone. Unless you are a light sleeper and the slightest noise is enough to keep you awake at night!

An ideal dehumidifier shouldn’t cross 40 decibels of sound at night. Devices with Peltier technology and Desiccant dehumidifiers usually come with whisper-quiet operation and let you enjoy a relaxed and stress-free environment in your RV.
