5 Best Small Dehumidifiers – 2021 Reviews

It’s important to take control of the environment you are living in, and the weather inside your home is one of the most tangible factors contributing to a good environment. Regardless of the weather, it is common for the air inside your home – be it your bedroom or bathroom – to feel sticky and humid, especially if you do not have proper ventilation outlets. This is because of the high level of moisture that’s present in the air that also encourages the growth of mold on the walls and ceilings. You constantly feel sweaty, and just staying inside the room might become a challenge!

In such a case, a small humidifier is your lifesaver. It is, indeed, the solution to all your humidity woes. What it does is that it extracts the moisture from the air inside the room, in the process of removing the dampness in areas like bathrooms and basements. The small dehumidifier is designed to absorb this sticky, muggy air and release non-humid, fresh air back to the room. This is done through a powerful fan that converts and condenses the humid air into water droplets. The final air released is pure and cooler that doesn’t let your clothes stick to your skin. Additionally, it also prevents the growth of bacteria in the form of mold or mildew, thus preventing allergies and infections.

Factors to Consider before Buying a Small Humidifier

There are several factors that need to be kept in mind while deciding which small humidifier to buy. The call depends on your requirements as well as the features of the small humidifier. Let’s take a look at some of the factors to consider before making the choice:

Weight of the Item

Most of the small humidifiers boast of being lightweight. Most of the ones listed in this article as well weigh less than 3 pounds. The lighter and compact the small humidifier is, the easier it is to transport it from one place to another. The smaller size also ensures that they can be placed in small areas like a closet or a wardrobe.

The Area Covered

The area covered by a small humidifier is as important as its size. Though, the purpose of a small dehumidifier is to cover small spaces so that they can work efficiently. The smaller the area you are aiming to cover, the better your product will perform. On average, a good small dehumidifier should cover about 200 square feet of area.


The higher the capacity, the less frequently will the water tank will need to be emptied and put back again. The water tank capacity depends on the size of the small dehumidifier. For areas that are slightly larger and not accessed frequently, it’s a good idea to buy a small dehumidifier with a large water tank capacity. 

Amount of Moisture Removed

This is undoubtedly one of the most important factors since this is the reason why you are buying a small dehumidifier. The dehumidification performance of the unit can decide whether it serves your purpose or not. Efficient small dehumidifiers hold the ability to remove about 80% of moisture from the air within an hour while the ones that are extremely small in size and use silica gel can take multiple weeks to remove just a fraction of that quantity.

There are other factors too that need to be considered while buying a small dehumidifier. For instance, how much noise it makes can be a deal-breaker for a lot of people since it shakes the peace of the environment. It should also be simple to operate and come without a lot of hassles. The warranty and guarantee on the spare parts can also be a big factor while making the final decision. 

Maintaining the Small Dehumidifier

Maintaining a small dehumidifier is important to extend its shelf life and keep it working at its utmost capacity. Bear the following points in mind to maintain your small dehumidifier.

Water Reservoir

The water tank, as soon as it becomes full, needs to be emptied to prevent the origin of any bacteria or mold inside the small dehumidifier. The water collected is stale and is the optimal breeding ground for various bacteria that can lead to allergies and infections for people around. 

Maintain the filters

Depending on your manufacturer, the filters of your small dehumidifier might need regular changes to ensure the effectiveness of the product and that it keeps absorbing the moisture as it should.

Adjust the Humidity Level

It’s important to adjust the humidistat to ensure that only the amount of moisture that’s necessary gets removed from the air. The ideal room humidity should remain between 45-50%. Going extreme either way can result in either extremely dry air or simply way too much humidity.

However, as long as the humidistat is adjusted to be maintained at the optimum level, there is no risk of any skin or health problems.

How Often Should the Water Tank Be Emptied?
