If your home humidity is still manageable, consider getting an often underrated mini dehumidifier. Here at Airfuji, we clocked in more than 72 hours of testing and comparison to bring you the absolute best small dehumidifier currently on sale. Regardless it is for wardrobe, bedroom, RV or bathroom, we have the right recommendation for you.

What Is a Small Dehumidifier?

Also known as a portable or mini dehumidifier, a small dehumidifier is a tiny device used to draw close range moisture in the air. The water will then drip down into the removable reservoir for emptying. By keeping moisture level below 50% mark, it will make the air much more breathable, free from allergens and bacteria. It will also create an inhabitable environment for mold, mildew, and dust mites. You will experience fewer allergy symptoms like cold and reduce the risk of an asthma attack. Most models are priced between $30-100 dollars depending on the dehumidifying capacity. Think about it as the scaled-down version for a standalone dehumidifier around the size of an electric kettle.

How Do Small Dehumidifiers Work?

Small/ mini dehumidifiers are all powered by thermoelectric technology. It uses a Peltier module, a fan, a cold side heat sink, and a hot side heat sink to convert energy via temperature difference or vice versa. This phenomenon dehumidification cycle is known as Peltier effects and is known for its silent and maintenance-free operation. You can learn more about how Peltier technology works here.

Why Should You Get One?

Everyone could do with a small dehumidifier. If you have a very tight budget and would want something that can be used straight out of the box. It is also best used in a small room or tight spaces like RV, bedroom or bathroom. Otherwise, a full-sized dehumidifier would make more sense.

Like Ivation, SEAVON MD-819 is another nominee for the best small dehumidifier bedroom. It is also our pick of the bunch despite not being the most well-known brand here.

On overnight operation, one can expect an estimated 170 square feet coverage in dehumidifying. This will keep you waking up fresh in the morning every day at less than 40 bucks in price tag.

SEAVON MD-819 is still very much a thermo-electric dehumidifier. It runs silently in the background without affecting your sleep as there are no moving parts.

Ivation IVADM45 is the most unconventional, small dehumidifier in the list. It looks nothing like the rest and in fact, it is a hybrid between a full-fledged and a mini model. Why do we say that? First, it has a front digital display that shows the room humidity level. None of the mini dehumidifiers have that. Then the boxy shape with grabbing handles resemblances of a 30-pint model. Finally, its moisture capturing capacity is beyond most models here but still locked at 2,200 cubic feet coverage. Great if you want a dehumidifier that can give you a little bit more.

So why do we think Ivation IVADM45 is the perfect small dehumidifier? Because it is still cheap, compact (for its class), and inexpensive. It also uses the same thermoelectric technology that is silent and energy-efficient. Adding the large 68 ounces reservoir, IVADM45 would be a great choice to break free of the monotonous option.

What are ACH and CFM?

ACH is the abbreviation for air changes per hour. It is the definition of the number of air passages made to the dehumidifier hourly. The higher the air changes frequency, the less airflow there is in the dehumidifier. CFM is the abbreviation for cubic feet per minute. It is used to determine the airflow velocity in cubic square feet space. You can get the value by multiplying the room size (height x width x length) and divide by 60. Most small dehumidifiers will only show you the official cubic feet it can cover so you can make comparisons straight out of it.

Things to Consider When Choosing The Best Small Dehumidifier?
