Nothing compares to retreating to the countryside in one of their recreational vehicles for RV enthusiasts. There is a thrill that comes with it. However, whereas an RV provides a fantastic chance to travel across the country, depending on the crowd of people inside you are travelling, it can get uncomfortably humid. The finest RV dehumidifier, a product specifically designed to avoid and treat this type of problem, is the solution.

Here are five of the most-purchased, well-received dehumidifiers in the market, offering comfort and effectiveness — a package deal you can’t say no to! 

5 Best RV Dehumidifiers

The reason why this one is among the best is that HomeLabs dehumidifier can remove approximately 22 pints of humidity from the air each day (the 2012 DOE requirement is 30 pints). This Energy Star accredited model is ideal for mid-sized to large rooms, absorbing moisture promptly and efficiently without putting a dent in your wallet.

It is a sleek, modern design with built-in wheels and grips, as well as a quiet fan that won’t drown out your present binge-watching frenzy or disturb a quiet ride across the country. 

You can adjust the moisture level to your preference, then turn it on for a continuous 24-hour cycle again until the tank is full, at which time it will shut off. A drain hose outlet is also provided for continuous draining.

The built-in pump compressor of HomeLabs portable dehumidifier helps to remove moisture. It also has a Turbo setting that boosts the fan speed from 118 CFM (cubic feet per minute) to 135 CFM (cubic feet per minute) for optimum moisture removal.

When dehumidifiers are in use, they produce heat (which is how they absorb moisture). This device isn’t meant to be used in the same space as an evaporative cooler, but it’s only good for rooms up to 1,500 feet wide. It is 15.2 x 10 x 19.7 inches, with a 0.8-gallon water tank. Ingenious, eh?

  • Quality of material
  • Durability

  • Hard to empty without spilling water
  • Isn’t cheap to run
  • Heat emittance


The IVADM45 consumes 72 watts of electricity. The IVADM35 has the same power rating consumption of 72 watts as the IVADM35. According to internet reviews and our experience, the IVADM10 is the most power-efficient thermo-electric dehumidifier. It eliminates 6.08 ounces of water every day with a power draw of 13.5 watts. As a result, while it eliminates roughly a fourth of the moisture every day as the IVADM45, it does it with one-fifth of the electricity.

IVADM45 took around less than fifteen minutes to dehumidify our 50 sq ft testing environment from 80% relative humidity to 70% humidity levels.

In terms of durability, the IVADM45 was found to be a sturdily designed, well-crafted dehumidifier. In general, thermo-electric dehumidifiers are fairly robust and reliable machines. This is due to the nature of the Peltier technology that allows them to dehumidify. Every thermo-electric dehumidifier has a Peltier module. 

It is sophisticated in design (minimum in complexity), making it tough to break. As a result, IVADM45 is exceptionally durable. You should know that material quality is quite important in these purchases!

This dehumidifier is extremely simple to set up and operate. Take everything out of the box, connect it with a power source, and select your desired humidity level on the front of the dehumidifier, and it’s ready to dehumidify right away.



  • Ease of use
  • Highly portable
  • Cost-effective
  • Well-built


  • Best for mid-sized spaces only

On paper, the Pro Breeze 500ml tank dehumidifier appears to be the ideal dehumidifier — it’s small, silent, and less than $50. It can extract 9 ounces of humidity every day — to give it a visual, it’s one of those little cups that come with a workplace water dispenser.

Because this dehumidifier is so compact and light, it doesn’t need a handle and can be simply handled.  Only with push keys – on and off – it’s as easy as any dehumidifier can be.

This makes sense given its performance level and pricing, as a cut-off or dehumidifying sensor would be unnecessary because it would have such a minor influence on the total humidity of the space.

When the dehumidifier is full, it will shut down automatically and the LED light will illuminate, indicating that the water tank needs to be drained. You would just have to empty the water reservoir and reinstall it in the dehumidifier.

Ultra-quiet and energy-efficient functioning in bedrooms, restrooms, and workplaces, with a power output of 23W per hour, equating to only 0.55kW after operating for 24 hours.

It also has a remarkably optimal performance in rooms ranging from 1200 to 2200 cubic feet. It is ideal for dealing with high humidity levels in your house, kitchen, bathroom, bedroom, RV, garage, or closet. 



  • Super cheap
  • Portability 
  • Energy-conserving 


  • Suitable for small areas

COSVII dehumidifier is a smart dehumidification that saves electricity. It lowers energy expenses by allowing your forced-air system to work more efficiently.

Any advice on its use would be to keep track of how the temperature, humidity, and room size affect the effectiveness of these dehumidifiers in the house. The more sticky the dryer is, the more effective it is. The higher the level of functioning, the smaller the room.

COSVII can work at temperatures ranging from 15°C to 40°C (59°F to 104°F). It is not recommended for usage in temperatures below 5°C or with relative humidity below 35 per cent RH.

There is also an automatic shut-off system. When the water tank is full, this compact dehumidifier with a 2000ml maximum tank will automatically shut off, and the pointer light will turn red to prevent flooding.

Lightweight and Frequently Used: This excellent little dehumidifier is small and light, making it easy to transfer to anywhere you need it. suited for rooms up to 480 sq.ft., and especially suitable for high mugginess in a variety of settings, including your house, restroom, storm cellar, room, storage, kitchen, RV, and so on. There’s no need to be concerned about moisture anymore!

The Keystone 35 (formerly KSTAD50B) and the KSTAD504D are very identical in appearance. It has the same features and performance as the original, except for moisture removal capacity and ideal covering area.

This equipment extracts 35 pints of moisture each day from 1,500 to 3,000 square feet of area. Even for a 35-pint device, the 6.4-pint (0.8 gallons) water tank is rather little. (Keep in mind that this model was once a 50-pint dehumidifier.)

The temperature range for Keystone is 41°F to 99°F, which is the industry standard for residential dehumidifiers. It works well at higher temperatures (60°F and above) and typical humidity levels, just like any other dehumidifier (50 per cent to 60 per cent).

While setting the timer, Keystone has a simple two-digit display that shows the humidity or the number of hours. The air intake is on the front of the unit, while the exhaust is on the side. By simply pushing up on the dust filter from behind the intake grille, it can be accessible.

Frequently Asked Questions

What Size Dehumidifier Do I Need For My Camper?

The capacity you’ll need mostly depends on the size of your RV. Even the largest RVs (up to 45 or 50 feet long) typically have a maximum square footage of around 400 feet. So even owners of large RVs might find that a dehumidifier rated for a 1,500-square-foot home is overkill.

What Relative Humidity Setting Should I Program Into My Dehumidifier?

While this is largely a question of personal preference, most recommendations suggest programming a relative humidity setting between 30 and 50 per cent. This, of course, is only possible with a dehumidifier that has a smart humidistat function. 

What is the difference between high efficiency and energy star?

Energy star dehumidifiers use less than 2.0 kilowatt-hours per litre of under 75 litres per day or 2.8-kilowatt hours per litre for 75-185 litres per day.

What Is The Best Location For A Dehumidifier?

The exact answer to this question depends on the size and layout of your RV. However, two of the best places to set up a dehumidifier are the living room and the bedroom. As these are the areas most of us spend the majority of our time in our RV, they are the areas where comfort is most important.

A humidifier’s capacity, or its ability to remove water within a certain range, is measured in “pints of moisture.” A 30-pint extraction rate device can remove moisture from a 300-square-foot area. A 50-pint dehumidifier has a 700-square-foot working range, whereas a 70-pint dehumidifier has a 1500-square-foot operating range.

Humidistat and Timer


A humidistat monitors the amount of humidity in the RV regularly and turns off the dehumidifier when the air reaches the ideal water vapour level. When you’re gone, a timer comes in useful. You might programme the machine to remove the vapour over a defined period to save energy while keeping the air dry.
