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!

  • LESS NOISE OUTPUT - The average noise output for all of the thermo-electric dehumidifiers we tested was 53.2 dB. On the other hand, the EDV-1100 was measured at 50.9 dB, 2.3 dB below average. Making it generate less noise to provide you a good night sleep at night..Compact size is perfect for bathrooms, closets, and R.V.sLow energy consumption
  • MAXIMUM PORTABILITY - The EDV-1100 couldn’t be any more portable. For one, it can easily be transported. Secondly, it is also one of the smallest, lightest thermo-electric dehumidifiers on the market.
  • LOW POWER CONSUMPTION - The Eva-Dry EDV-1100 has a manufacturer specified power draw of 22 watts. That makes it low on energy consumption so you can save on your electricity bill and also helps the environment. Capacity - 16 ounces
  • SUPERIOR QUALITY – It is made from high quality and superior materials making it durable. It also has renewable reservoir which absorbs musty odors from stagnant air and also eliminates odors and fungus.
  • PLUG AND PLAY SETUP - This couldn’t be easier to use. Simply plug it in and turn it on. It will immediately start dehumidifying. If the condensate collection bucket fills up the “FULL” LED will light up and the dehumidifier will automatically shut off.

This is our top recommendation.

  • 1,500 sq ft Dehumidifier: Our dehumidifier removes up to 22 pints (30 pint 2012 DOE standard) of moisture from the air per day. This Energy Star certified model is fit for medium to large rooms, to quickly and effectively absorb moisture without racking up your energy bill.
  • Designed For The Modern Home: That most dehumidifiers are clunky eyesores is news to nobody. We designed with the modern consumer in mind: a sleek clean look, convenient built-in wheels and handles, and a quiet fan that won’t drown out your current binge-watching obsession.
  • Super Easy To Use: Dehumidifiers don’t need to be complicated, so ours isn’t. Adjust to your ideal moisture setting, then let it run its continuous 24-hour cycle until the tank is full, at which point it will automatically shut-off. There’s also a drain hose outlet for continuous draining. The hose is not included; we recommend a ⅝” diameter garden hose with an internal threaded end, and optionally Teflon tape for extra security.
  • Eliminates Moisture Effectively: Our portable dehumidifier reduces moisture through its built-in pump compressor. It also features a Turbo mode that increases fan speed from Normal Air CFM 118 (cubic feet per minute) to High Air CFM 135 for maximum moisture removal.
  • Important Things To Know: Dehumidifiers emit heat when in use (that’s how they absorb the moisture). This product won’t work in the same room as an evaporative cooler, and is intended for any indoor space up to 1,500 square feet. It measures 15.2 x 10 x 19.7 inches, has a 0.8 gallon water tank capacity, and removes up to 22 pints of moisture from the air per day.

For very large RVs, toy haulers, and fifth wheels that are plugged into park electricity in high humidity areas, this will protect your RV from must and mold.
