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!

We start out with the highest recommended, the Eva Dry. Check the notes under each product for our thoughts.

  • PETITE DEHUMIDIFIER REMOVES MOISTURE: When ambient temperatures are above 50°F(10°C) and the relative humidity is above 55% you will begin to see the collection of moisture in the reservoir. With higher temperatures and relative humidity levels, the unit can absorb up to 8 oz. per day! Unit is not recommended for temperatures below 50°F(10°C) or relative humidity levels below 50%.
  • 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.

hOmeLabs 4 Gallon (30 Pint) Dehumidifier Energy Star Safe Mid Size Portable Dehumidifiers for Medium Large Spaces up to 1000 Sq Ft with Fan Wheels and Drain Hose Outlet to Remove Odor and Allergens

 out of stock
as of June 22, 2024 4:13 am


  • 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 moisture-removing, Energy Star certified beast 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. Durability is key, too, which is why we offer a 1-year warranty, plus an additional 1 year if you register on our website.
  • 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. Don’t got time for that? 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 Moistness: Moist is a bad word. 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 165 (cubic feet per minute) to High Air CFM 188 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 1 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.
