How to Choose a Dehumidifier

There are certain things to look into once you have decided to purchase a dehumidifier.

Humidity Levels

First, you must be aware of the humidity levels. Are you really in need of a dehumidifier? If humidity is affecting your household items like wooden work and if it is aggravating allergies and flare-ups of chronic asthmatic people, then a dehumidifier is a good option to invest in.

Space Demands

Next, you need to be aware of the space available. How much of the area needs dehumidification? Your pint capacity is largely dependent on the severity of humidity and the space available. The drain hose attachments must be looked into as well. The output of the condensed water should be smooth for the dehumidifier to work at its optimum levels. The drain hose attachment lessens the burden of continuously emptying the water reservoir. If it is not present, then a dehumidifier with an automatic shut off system when the water tank fills is useful.

What Added Features Are There?

After looking into the basics, see if the dehumidifier has additional features. The option of ducting is key when you have more than one room to cater to. Wheels and handles must be kept in check to provide mobility and ease of handling.

Review of the Best Dehumidifiers

What is a Dehumidifier?

A dehumidifier is essential in your household as it will not only aid in your sleep, but will also keep harmful bacteria, mold, and dust mites at bay. A dehumidifier reduces the amount of humidity in your atmosphere to provide comfort and eliminate any stale odors. This prevents the growth of mildew and mold by depriving the air of water. Some people even find it hard to breathe in areas with high levels of humidity. So, a dehumidifier comes in handy at such pressing times.

This electrical appliance maintains humidity levels and has two variants to help in doing so. These are condensate dehumidifiers and desiccant dehumidifiers. The former simply condense the water vapors while the latter uses a substance that absorbs the moisture.

How Does a Dehumidifier Work?

The regulation of humidity by dehumidifiers is done commonly by refrigerant based methods. Mechanics pertaining to this phenomenon circulate around the simple principles of condensation and evaporation.

Photo credit:

It works similar to a refrigeration unit; the moist warm air enters the unit and condenses on the cool coils within the machine. Imagine how on a hot day your cold glass of water forms condensation around it. In the same way, the coils in the unit are at a lower temperature, causing the air around them to condense. The condensate is retained, leaving the air cool and moisture free.

However, note that it is not similar to an air conditioner. The air is slightly re-warmed as it passes over the fan of the dehumidifier, confirming the high efficiency of the dehumidifier, as the dry and warm air draws in more moisture.

What Size of Dehumidifier Do I Need?

There are different sizes of dehumidifiers available in the market. Your purchase is largely dependent on the space needed for dehumidification and the moisture levels in that area.

Danby Energy Star 70-Pint Dehumidifier

Large, medium, small, and whole house capacity dehumidifiers are available. If the area is simply damp with occasional staleness, then for 500 sq. ft. to 1500 sq. ft., 40 pints or fewer is perfect. If the area is larger than 2000 sq. ft., then around 41-60 pints prove to be beneficial. Remember, the scenario changes as the moisture levels increase. If you have a relatively smaller area but high humidity, the pints needed to dehumidify increase

Types of Dehumidifiers

Dehumidifiers may seem like simple devices that function all the same, but that isn’t entirely the truth. Dehumidifiers aren’t all the same. There are, in fact, three different types.

Compressor-Based Dehumidifier

These humidifiers are usually large sized, and with the large size, comes greater water holding capacity that can amount to as much as 10 gallons. Given their size and capacity, these dehumidifiers can be used in rooms of all sizes, small to extra-large, and that too at any level of humidity. The only con of these models is that they’re hard to handle and move given their size.

Thermo-electric dehumidifiers

Thermo-electric dehumidifiers, on the other hand, are not as big in size, and neither is their water holding capacity, usually amounting to only a few ounces in a day. Given their size, these models are perfectly portable and easy to store. However, they only work efficiently in small and closed spaces that have comparatively lower levels of humidity.

Desiccant Dehumidifiers

These humidifiers use a substance that absorbs the moisture instead of a compressor or a thermo-electric system like the other two types. Just like thermo-electric dehumidifiers, these devices are also efficient only for smaller spaces that do not need large scale dehumidification.

Afloia Portable Electric Dehumidifier


Dehumidifiers can work wonders for the air around your home, given that you’ve chosen the right one and the best one for your needs. Keep in mind all the types of dehumidifiers that you can choose from, and all the important aspects of the dehumidifier that need to be considered, and you’ll find the job of selecting the perfect dehumidifier to be a lot easier.

People Also Ask

Below are some common FAQs:

How Long Should My Dehumidifier Run Per Day?

The ideal answer to this question is simple. Run it for 24 hours a day. That is also what most brands of dehumidifiers will tell you because that’s the ideal running time to keep the levels of humidity according to your liking.

But that running time won’t be ideal for your unit. If you do run your dehumidifier, you’ll end up spending a lot more than you should be. For the optimal working of your device as well as the optimal humidity levels, you can run your dehumidifier for up to 10-12 hours, and safely so.

How to Use a Dehumidifier

Dehumidifiers are not very complicated machines to use. Just a couple of commands, a few settings, and you’re good to go.

Make sure that you place the unit in the most humid room, such that air is allowed to circulate around it. It is essential to make sure that the unit isn’t placed against the wall.

Connect your dehumidifier to a power outlet, turn it on and adjust its settings according to the manual. This may likely include inputting a desired level of humidity. For this, you may need to measure the current level of humidity and evaluate how much dehumidification you need.

Make sure that you close the doors and windows of the room where a dehumidifier is working as open spaces may reduce the efficiency of the units. Moreover, you need to ensure that you regularly check and empty the water tank, and once in a while, pay attention to any required maintenance for the device.

How Much Power Does a Dehumidifier Use?

The power used by dehumidifiers depends upon a number of factors such as the type of dehumidifier being used, its size and its use. In general, a standard electric dehumidifier operates at 280 watts-hour, which is a considerable amount of power being used.

A better idea of how much power is used by a dehumidifier can be made by the fact that dehumidifiers use twice as much as electricity annually as a refrigerator would.

Why Does a Dehumidifier Ice Up?

You may notice that your dehumidifier is starting to frost up. Do not worry; this doesn’t put your unit at grave risk. This icing is mostly due to the temperature of the room itself, or possibly due to the air flowing through the unit. These problems can be quickly fixed by temporarily shutting down the unit and reviving the airflow through it. If that doesn’t work, you may refer to the provided manual or seek out customer care.
