High humidity in small spaces is never a good thing. Especially when that space is your RV. Humidity and condensation in your RV are not only annoying but can be damaging and if not handled quickly. In this article, we are going to give you the best budget-friendly RV dehumidifier and the best overall.

How Do You Dehumidify an RV?

As we moved across the country and started to experience humidity inside the RV from cooking, showers, rain, and weather, we would turn on the roof fan and open the windows. But we quickly learned that wasn’t going to cut it. There are a few ways you can dehumidify an RV that are much better than simply using a fan.

DampRid Buckets

DampRid is made of calcium chloride and dissolves as it absorbs moisture. Meaning, once the chemical has dissolved, you will need to replace it with more.

If you’re on a budget, the DampRid Refillable Buckets can help with moisture in the air but aren’t your best attack. We recommend tossing these in your RV storage compartments or closets as they work best in smaller spaces.

  • DampRid Refillable Moisture Absorbers are convenient 10. 5-ounce cups that attract and trap excess moisture out of the...
  • DampRid eliminates odors by absorbing excess moisture out of the air that creates unpleasant, musty smells.

Eva-Dry Renewable Mini Dehumidifier

The Eva-Dry Mini Dehumidifier is another budget-friendly option. We consider it a step up from the DampRid buckets as there is no mess and no refills to buy. This type of RV dehumidifier uses silica gel to absorb moisture. When the beads turn blue, it’s time to plug it in to dry them out. Once they are dry, it’s good to go again!

The Best RV Dehumidifier

The best RV dehumidifier, and the one that we’ve been using for years, is the Ivation 13-Pint Desiccant Dehumidifier. We love this product because it is small but powerful. It works in temperatures from 33°F to 104°F and even removes mold and mildew.

You can adjust the humidity level, just in case you don’t want the room too dry (yes, we’ve actually done that with this machine!). The noise levels are practically nonexistent and we love how lightweight it is.

This portable dehumidifier holds 13-pints of water, so feel free to run it for extended periods of time without worry it will fill up. And when it does fill up, it will alert you with a few beeps and shut off automatically.

Budget-Friendly Option

If you’re looking for an RV dehumidifier that will still get the job done but not take a hit on your wallet, we recommend the Eva-Dry Petite Dehumidifier. It is only one pound and can hold up to 16 ounces of water. This mini dehumidifier is perfect for RV life as it can be moved from room to room to absorb moisture in your whole rig.

Another great feature is that it has low power consumption and only draws 22 watts. So even when boondocking in high humidity, you don’t have to suffer.

What Size Dehumidifier Do I Need For My RV?

When shopping for a dehumidifier for your RV, you might notice that they have different square foot ratings. Even the largest RVs come in at 45 feet and around 450 square feet, so you shouldn’t have a problem finding the right-sized dehumidifier. Additionally, you are able to move any of the above dehumidifiers around. So anything rated for a bedroom, bathroom, or storage closet should do the trick in small spaces.
