Dehumidifiers Product Database

hOmeLabs HME0091

The hOmeLabs HME0091 is my top choice when it comes to RV dehumidifiers because it manages to pack in all the features you'd want without going overboard on size or price. 

While the manufacturer lists this unit as being rated for up to 1,800 square feet, that number is more theoretical than practical.

With its 8 pints per day moisture removal, it's best suited for a mid-sized Class C RV or a similar compact living space.

That's not a bad thing, though, since in a smaller environment you don't need (or want) an oversized commercial unit roaring away in the background.

One of the things I like most about this model is that it's incredibly quiet. When you're parked at a campground or trying to sleep in a tight space, noise levels matter. 

Add in WiFi controls, and it's easy to check on humidity levels or adjust settings on this hOmeLabs model without even getting up from the couch or bed. 

The built-in tank is on the smaller side at just 3.2 pints, so if you're in a particularly damp climate, it will fill quickly.

Fortunately, hOmeLabs includes a 3.3-foot gravity drain hose that can be routed into your sink or shower, which makes life much easier on the road.

For RV use specifically, I'd recommend skipping the caster wheels. They can be installed, but removing them later is a hassle, and honestly, you don't need rolling wheels in a camper where the unit stays put. 

On a recent coastal trip, I used this model for a week straight, and even after a couple of back-to-back rainy days, it kept the interior air fresh and dry without requiring me to constantly empty the tank.

Pro Breeze PB-03-US

The Pro Breeze PB-03-US is an excellent option for smaller RVs, vans, and compact living spaces where a full-size dehumidifier would be overkill. 

With coverage for about 215 square feet, it's best suited for Class B RVs or areas like a small bathroom, closet, or even a bedside table.

I really like this one for tight spaces because it's simple, reliable, and doesn't take up much room. At just over 11 inches tall, the Pro Breeze is easy to tuck out of the way.

This dehumidifier uses Peltier technology, which makes it lightweight and energy efficient, though it does mean performance is more modest compared to compressor-based models. 

That's not going to feel like a major difference in very humid conditions, especially when compared to something like the hOmeLabs HME0091, but in mild to moderate humidity, it works quite well. 

The built-in tank of the Pro Breeze can hold 52 ounces, so unless you're in a particularly damp spot, you'll only need to empty it every few days.

There's no gravity drain option, so you're limited to tank use, but that's a fair tradeoff at this size and price point.

One thing to note is that Peltier models like this tend to put out a bit of warmth while running. In cooler weather, that's barely noticeable, but in summer, you may not appreciate the extra heat. 

Still, for just around $65, the Pro Breeze is a simple on-and-off solution for humidity control in smaller RVs. If you want something compact and hassle-free for a van or camper, this is one of the best options available.

Afloia Q10

The Afloia Q10 earns a spot on this list because it's the only model that combines a dehumidifier and an air purifier in one unit.

That dual functionality makes it especially handy for small Class B motorhomes or compact travel trailers where space is at a premium.

You can run the purifier and dehumidifier together or separately, which gives the Afloia Q10 year-round usefulness whether you're managing summer humidity or just filtering the air during allergy season.

With a 216 square foot coverage area and 1.5 pints per day moisture removal, the Afloia Q10 is well-suited for smaller RVs. 

Compared to the Pro Breeze, the Q10 offers just a bit more capacity along with more flexibility. 

The built-in tank holds 2.11 pints, which is decent for a compact model, and Afloia includes a 6.5-foot gravity drain hose, which is long enough to make continuous drainage more practical in different RV layouts.

Noise is another highlight of this Afloia model. On low, it runs at only 25 decibels, which is barely noticeable, and even on the highest setting, it only reaches about 45 decibels. 

That makes it a great option for anyone who wants to keep it running overnight without disturbance.

Unlike the Pro Breeze's simple on and off switch, the Q10 offers three fan speeds, making it easier to balance performance with quiet operation.

One thing to keep in mind is the filter. You'll need to replace it every 6 to 12 months, and while off-brand filters are available, the Afloia ones (about $18 each) tend to perform more reliably. 

That said, at under $100, this unit is a budget-friendly, space-saving choice for RVers who want both drier and cleaner air.

Midea Cube 20 pints

The Midea Cube 20 Pints is a fantastic option for larger RVs, especially Class A rigs or big trailers that spend most of their time parked at a campsite with shore power. 

This Cube can remove up to 20 pints of moisture per day, which makes it one of the most powerful models on my list.

If you're spending the summer in a humid climate, it's a great way to take the load off your air conditioner while keeping the air comfortable and fresh.

Like my top choice, the hOmeLabs HME0091, the Midea Cube includes WiFi controls and smart features, which is impressive given that it's priced in a similar range. The big difference, of course, is capacity. 

While the hOmeLabs pulls 8 pints per day, the Cube more than doubles that performance. It's also Energy Star certified, which means you don't have to feel guilty about plugging in a more powerful machine.

One of the features I really like about the Midea Cube is its unique nesting design. Even though it comes with a massive 3.2-gallon tank and can run continuously with a gravity drain, the whole unit collapses down into a neat cube just 13.5 by 13.5 inches.

That makes it far easier to stow away when you're on the move compared to most dehumidifiers in this class.

Overall, the Midea Cube is best for RVers who plan to settle into one spot for days or weeks at a time. 

It's not something you'd run off a small generator, but if you've got shore power and need serious moisture control, this one will handle it without breaking a sweat.

Waykar PD160B

The Waykar PD160B is the highest-capacity model on my list and the one I recommend if you're dealing with extremely humid conditions in a large RV. 

With the ability to remove up to 30 pints of water from the air each day, it's powerful enough for an oversized Class A motorhome or a big travel trailer parked on shore power.

It's also a smart choice to run periodically during the off-season when your RV is in storage, since keeping humidity under control helps prevent musty odors and mold growth from creeping in over time.

Although the Waykar is the biggest unit here, it is still fairly compact at 9 by 12.2 by 20.9 inches, though you'll need to plan ahead for where to store it when traveling. 

Like the Midea Cube, it offers both a tank and gravity drain option, but in this case I really only recommend using the gravity drain. 

The tank is tiny compared to its output - just 5.28 pints. With 30 pints of daily capacity, you'd be emptying it several times a day to keep up.

Setting it up with a drain hose into your RV's sink or shower is the only practical way to use this Waykar model.

One thing I like about this unit is that despite its large capacity, it doesn't feel overbearing in the space.

On a muggy weekend along the Gulf Coast, I set it up in a friend's motorhome, and within a few hours the difference in comfort was obvious - the sticky air was gone, and the space felt crisp and breathable again.

Do I really need a dehumidifier in my RV?

Yes, a dehumidifier helps prevent condensation, mold, and musty odors that quickly build up in the compact space of an RV.

Can I leave a dehumidifier running in my RV overnight?

Yes, most RV-friendly dehumidifiers are designed for safe continuous use, especially when draining into a sink or shower.

What is the ideal humidity level for an RV?

The best humidity range for an RV is between 40-50% to stay comfortable and avoid moisture damage.

Will a dehumidifier work in cold weather inside my RV?

Yes, but compressor models are less effective in cooler temps, so desiccant dehumidifiers are better for cold climates.

Can I use my home dehumidifier in an RV?

Yes, but size and portability matter. Home models may be bulky and harder to store in an RV. Like any appliance, keep the wattage usage in mind when running in your RV.
