Buying Guide: Tank Size, Coverage, Noise and Drain Options
Choosing the right dehumidifier for your RV comes down to a few key factors. These are all thermoelectric (Peltier) units, not compressor-based, which means they are quieter, lighter, and use less power. But they also work slower in very humid conditions.
Here's what you need to think about.
Tank Size: How Often Do You Want to Empty It?
The tank size is the biggest practical difference between these models. They range from 35 oz up to 95 oz. A smaller tank like the 35 oz on the TABYIK means you will be emptying it every 8 to 12 hours in a humid climate.
A 95 oz tank like the one on the BEDRED or NineSky can last a full day or more, depending on conditions.
If you are boondocking or don't want to wake up to a full tank, aim for 68 oz or larger. The 68 oz models from the drain hose unit and the bedroom/bathroom unit offer a good middle ground. The 95 oz tanks are the best for minimizing interruptions.
Coverage: Match It to Your RV Size
Coverage ratings are based on ideal conditions. In a real RV, with windows, doors, and less insulation, expect the effective coverage to be about 60 to 70 percent of the claimed number. A unit rated for 1000 sq ft will realistically handle a 30 to 35 foot motorhome.
A 500 sq ft unit is better for a travel trailer or a smaller Class C.
The Small Dehumidifier Home 44OZ is only rated for 260 sq ft, making it ideal for a pop-up camper or a van. The TABYIK covers 280 sq ft. For anything larger than 300 sq ft, you should look at the 68 oz or 95 oz models.
Noise Level: How Quiet Is Quiet Enough?
All of these units are Peltier-based, which means they are inherently quieter than compressor dehumidifiers. The quietest unit here is the TABYIK at 28 dB, which is barely audible. The BEDRED and the bedroom/bathroom unit are also very quiet, with most owners reporting they are fine for sleeping.
The 60 OZ dual-fan unit is slightly louder because of the two fans. If you are a very light sleeper, the TABYIK or the ToLife with its sleep mode are your best bets. For most people, any of the top five units will be quiet enough.
Drain Options: Tank or Continuous Hose
Only two models in this lineup include a continuous drain hose: the 68 oz Small Drain Hose Up and the bedroom/bathroom unit. This is a huge convenience if you are parked at a site with a sewer connection or a sink drain. You can route the hose and never touch the unit.
The other models rely solely on the tank. If you don't want to empty a tank, consider the 68 oz drain hose model. If you are okay with emptying the tank every 12 to 24 hours, the 95 oz units are great.
To see how these factors play out on real picks, compare the BEDRED Dehumidifier 95OZ Home 1000 sq, Dehumidifier 68oz(2000ml) Small Drain Hose Up and the Small Dehumidifier Home 44OZ Quiet Auto reviewed above.
Who Should NOT Buy Best Dehumidifier for RVs
These thermoelectric dehumidifiers are the wrong purchase for two kinds of buyers. Here's who they are and what to look at instead.
You Live Full-Time in a Very Humid Climate
If you are a full-time RVer in the Gulf Coast, the Pacific Northwest, or any area with consistently high humidity (above 70 percent), a Peltier dehumidifier will struggle to keep up. These units work best in moderate humidity. In very damp conditions, they remove moisture slowly and may not lower the humidity enough to prevent mold.
What to look at instead: A compressor-based dehumidifier, like a standard 30-pint or 50-pint home unit. They are larger, louder, and use more power, but they are much more effective in high humidity.
You Need to Dehumidify a Very Large RV or Multiple Rooms
These units are designed for a single room or a small open space. If you have a 40-foot motorhome or a toy hauler with multiple rooms, one of these small units won't be enough. You would need to run multiple units, which adds complexity and cost.
What to look at instead: A larger whole-RV dehumidifier system or a single 50-pint compressor unit placed in the main living area. You can also use two smaller units, like the BEDRED and the bedroom/bathroom unit, one in the main area and one in the bedroom.
Final Verdict
The best overall pick for most RV owners is the BEDRED Dehumidifier 95OZ. It has the largest tank, the quietest operation, and the widest coverage. It's the right choice for anyone with a mid-size to large RV who wants to empty the tank as little as possible.
Want a continuous drain hose instead? Get the 68 oz Small Drain Hose Up. It's the best set-and-forget option for anyone parked with a sewer connection.
Need something for a tiny camper or van? The Small Dehumidifier Home 44OZ is compact, loaded with features, and perfect for small spaces.
If you are a full-timer in a very humid climate, jump back up to the Who Should NOT Buy section. A compressor-based unit will serve you better.
FAQ
What's the best Dehumidifier for RVs overall?
The BEDRED Dehumidifier 95OZ is the best overall pick. It has the largest 95 oz tank, quiet operation, and covers up to 1000 sq ft, making it ideal for most RVs.
Can I leave a dehumidifier on all night in my RV?
Yes, all of these units have auto shut off and are designed for continuous operation. The ToLife and TABYIK have sleep modes for even quieter nighttime use. Just make sure the tank is empty before you go to bed, or use a model with a continuous drain hose.
How often do I need to empty the tank?
It depends on the humidity and the tank size. In moderate humidity, a 95 oz tank can last 24 hours. A 35 oz tank like the TABYIK may need emptying every 8 to 12 hours.
In very humid conditions, you may need to empty any tank more frequently.
Do these dehumidifiers work in cold weather?
Thermoelectric dehumidifiers are less effective in cold temperatures. They work best above 60 degrees Fahrenheit. Below that, the moisture removal rate drops significantly.
The Small Dehumidifier Home 44OZ has a defrost function that helps, but it's not as effective as a compressor model.
Are these dehumidifiers safe for use in an RV while driving?
It is not recommended to run a dehumidifier while the RV is moving. The water in the tank can spill, and the unit could tip over. Always empty the tank and secure the unit before driving.
Do I need a dehumidifier in my RV if I run the air conditioner?
Air conditioners do remove some moisture, but they are not as effective as a dedicated dehumidifier, especially in humid climates. A dehumidifier will help keep the interior dry and prevent mold and mildew, even when the AC is running.
