High humidity in small spaces is never good, 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 will 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. Once the chemical has dissolved, you must 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 Pure Linen Refillable Absorber-10.5oz Traps Moisture for Fresher, Cleaner Air, 10.5oz cups - 4 pack, Blue, 4 Count
  • 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 dehumidifier uses silica gel to absorb moisture in your RV. When the beads turn blue, it’s time to plug them 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 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 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 difficulty finding the right-sized dehumidifier.

The size of the dehumidifier you need for your RV depends on the size of your RV and the level of humidity you need to control.

Generally, a small to medium-sized RV will require a dehumidifier with 20 to 30 pints capacity.

Larger RVs in humid areas may require a dehumidifier with a higher capacity, up to 70 pints per day.

Choosing a dehumidifier that is the appropriate size for your RV is important to ensure effective moisture removal without wasting energy.

Additionally, look for a compact and portable dehumidifier like our recommendations above for ease of use in a smaller space like an RV.

Is it OK to leave a dehumidifier on overnight?

It is generally safe to leave a dehumidifier on overnight as long as it is in good condition and used according to the manufacturer’s instructions.

Dehumidifiers are designed to remove excess moisture from the air, which can help prevent mold, mildew, and other moisture-related issues.

Protect Your RV From Humidity Damage

Now that you know the different solutions to combat humidity in your RV, there’s no excuse not to have a dehumidifier. Keeping your RV dry can protect it from moisture and humidity. An RV dehumidifier is a simple solution to prevent a big headache.
