The Top RV Dehumidifiers: Small & Portable Motorhome Dehumidifiers

Looking for a dehumidifier for your motorhome or trailer? Look no further, we’ve put together a comprehensive list for you based on the best reviews from other RV owners like you. (And no, you don’t have to buy your new appliance from Camping World… you can get it online at Amazon!)

Unfortunately there is no such thing as a 12 volt dehumidifier specifically for RVs, but there are plenty of miniature versions that only take a small amount of energy, which your RV will be able to run either off solar if you’re boondocking or off park electricity if you’re plugged in at a campground.

Now, the best RV dehumidifier for your needs will depend on a few things…

How much humidity do you have in terms of both people and weather, and how big is your RV? The more humidity and space you have, the more dehumidifyng power you’ll need. In fact, you may need more than one small dehumidifier to keep your whole RV dry and free of dampness if you have a very large space or many people.

If your RV is on the smaller side, some simple drying crystals may be all you need to suit the humidity in your rig.

We cover all of the options below!

  • PETITE DEHUMIDIFIER REMOVES MOISTURE: When average temperatures and relative humidity levels are high, the unit can absorb up to 16 oz. per week when run continuously! The unit will absorb less moisture at colder temperatures and drier environments. It is not recommended for temperatures below 50°F(10°C), relative humidity levels below 50%, or spaces larger than 122 sq. ft.
  • WHISPER-QUIET: The average noise output of thermo-electric dehumidifiers is 53.2 dB. The EDV-1100 has been measured at 33 dB, 23 dB below average. It generates less noise to help you sleep better at night.
  • AUTO SHUT-OFF PROTECTION: When the water tank is full, the dehumidifier will auto shut off, and the full light will light up yellow to inform you. It is very safe and convenient to use when you are not at home.
  • PORTABLE DEHUMIDIFIER FOR HOME: With a compact size of 6.5X5X11 inches, it can be easily placed most anywhere, helping you get the excess moisture out of the air in your bedroom, bathroom, RV, closet, and more.
  • AUTO RESTART AFTER A POWER INTERRUPTION: Once the power is restored after a power failure, the appliance will continue to operate normally.

This is our top recommendation.
