Why You Need an RV Dehumidifier (and the Most Portable Options)

Why You Need an RV Dehumidifier (and the Most Portable Options)

Have you ever been in your RV and noticed that moisture is building up on the inside of the windows and walls?

This is because you have a lot of moisture in your RV and it has nowhere to escape.

While it might not seem like a big problem, you don’t want moisture in your RV especially for long periods of time.

Mold will quickly grow and ruin things if not treated quickly and properly. You need a portable RV dehumidifier to combat moisture.

We’ve put together this guide to RV dehumidifiers to help you find the best option for you. Let’s dive in!

What Are RV Dehumidifiers? 

An RV dehumidifier is a device that sucks the moisture out of the air. There are RV specific dehumidifiers, but household ones are great, too.

These machines act like a sponge that soaks up the moisture and drains the water into a bin for collection.

When choosing the right RV dehumidifier, you want to get one that will be the right size for your space. The bigger your RV the bigger dehumidifier you will need.

Why Do RVers Need Dehumidifiers? 

The biggest reason you need a dehumidifier in your RV is to stop mold from growing. Moisture can get into all the nooks and crannies in your RV and mold loves cold, dark, moist places.

When mold starts to grow, it’s extremely hard to get rid of. Mold can cause severe health issues in humans and pets. Reducing the moisture in your RV will inhibit mold growth and prevent illness.

Benefits of a Dehumidifier for your RV: 

  • Prevent mold and mildew: benefit number one is keeping mold and mildew out of your RV to reduce any health risks.
  • Keeps air fresh: it’s also a great way to keep the air fresh in your RV. When it’s cold out and you keep the windows closed, the air can get stale. Dehumidifiers help keep your air clean and fresh.
  • Can help it feel cooler inside: Humidity is a huge heat factor. If you’ve ever been in the southeast, you know what I mean! Reducing humidity will make your indoor RV temperature feel a lot cooler in those muggy, warm areas.

Fridgidaire 50 Pint Dehumidifier 

The Fridgidaire 50 Pint Dehumidifier is one of the best on the market.

This portable RV dehumidifier can remove up to 50 pints of water a day from the air. It holds up to 2-gallons before needing to dump. Once the fill tank is full, it will automatically shut off so it doesn’t overflow. You can even set it up to attach a hose and have a continuous dump so you never have to empty the holding tank.

Average Price: $330

What People are Saying: “This is fabulous! It works very quietly, easy to use and it already pulled 3.5 gallons of water (humidity) in my basement!! My humidity levels are holding steady at 43% that is awesome and my base will remain dry and clear from mold and mildew smells. Love this!! The best money spent!” – Amazon Review

Keystone 35 Pint Dehumidifier

The Keystone 35 Pint Dehumidifier is another great choice.

This dehumidifier works best in a space of no larger than 3000 sq. feet and can consume 50 pints of moisture out of the air a day. This product has many control settings depending on how fast you need it to work. It also has an option to attach a hose for continuous draining without having to constantly dump the holding reservoir. 

Average Price: $190

What People are Saying: “I found many positive detailed reviews on this unit, and they were fairly accurate. This beautifully designed, well-built dehumidifier (the first one I ever bought) seems to work great. Its display gives an accurate reading of the ambient humidity and its simple keypad allows for several modes of operation and adjustment. It’s also quiet, which I love.” – Amazon Review

Pro Breeze 150 sq ft Dehumidifier

The Pro Breeze is a small portable RV dehumidifier that’s perfect for smaller spaces.

You don’t want to use this dehumidifier in a space larger than 150 sq. feet. This product removes 9-ounces of water per day and has a holding tank of 16-ounces. It automatically shuts off once full. This is a small and quiet machine. 

Average Price: $45

What People are Saying: “I liked that the description explained what to expect from this device in performance. The wattage was 20 Watts, important in an RV. I would like to have seen a noise level listed, I was also unsure of the physical unit’s size. I see one set of measurements but I think that’s of the box and not the unit. Clear that up and this review has all the information you need.” – Amazon Review

Invisipure Hydrowave Dehumidifier

The Invisipure Hydrowave is a nice mid-size portable RV dehumidifier.

It works well in spaces up to 300 sq. feet. On average it can remove up to 1.7 pints of moisture a day. The holding tank holds up to 2-liters before it automatically shuts off. The machine is quiet and not too big that it takes up a lot of space. 

Average Price: $80 

What People are Saying: “Bought to use in our 29’ Coachman travel trailer. It works much better than expected, given the price point, indeed it is perfect for the space. In the last three days, it has pulled 3 cups of water into the reservoir. When we arrived at the campground, the trailer was muggy at setup. Within an hour, the difference was noticeable and humidity was at a very comfortable level within an hour or so after that.” – Amazon Review

Honati Home Portable Dehumidifier

The Honati Home Portable RV Dehumidifier is another good mid-size option.

It works well for areas no bigger than 269 sq. feet. It can remove up to 750 ml a day with a holding tank of 2000 ml. The machine has an auto shut off when the tank gets full. This one is a popular option because of how quiet it is. 

Average Price: $70

What People are Saying: “I’m really glad we got this product. The windows in our ground level apartment had so much condensation in the mornings that it took a microfiber rag and at least four paper towels per window to dry them out. We left the dehumidifier running overnight… no condensation! This has made my morning. The unit is quiet and portable and seems to be taking care of my excess moisture problem. So far we are satisfied with our purchase.” – Amazon Review

    I have a large dehumidifier for my 32-ft jayco and I’ll never have an RV without one. I’m amazed at how much moisture this takes out of the air which then feels so much warmer without the humidity and I live in the Seattle area so you know I get a lot. I think mine holds about a gallon and I empty it two times a day but it makes an absolutely huge difference. Carolyn Clark

    I live in an a pretty small apartment in the southern US where it gets VERY humid during the summer months. I decided to try out little dehumidifier just to help maintain a cool, dry space in my bedroom. I’ve used it for about a month now and so far so good! Although it’s small, it really does pull a lot of moisture out of the air.
