How To Choose A Dehumidifier That’s Right For You

by Raymond Archambault

A dehumidifier is an appliance that is particularly designed to prevent excess moisture in the air from drying up and turning into a mold or mildew problem. They are available for different sizes of your space, according to your needs.

Excess humidity can lead to several problems in the home, such as musty odors, warped wood, and peeling paint. If left unchecked, it can also cause mold, which is undesirable for most people.

It’s important to consider the environment surrounding your home. While most dehumidifiers work well in residential settings, there are several things you should know when selecting one that’s right for you. If you’re looking to invest in a new piece of home improvement equipment, it’s wise to start by considering the size and needs of your space, along with what’s in the room. Then think about the location of your unit and how frequently it will be used. Finally, consider the types of objects you typically put in your room, and the amount of moisture that’s present.

If the high humidity level in your home is bothering you, what can you do? If one word were to describe this answer, it would be a dehumidifier. Now that we’ve told you how to choose a dehumidifier, read on to learn more about them!


Water Damage, Mold, and Your Health

This tool is used to remove moisture in the air. This is an important preventative measure, given that mold likes to be drawn to many common building materials like ceiling tiles, wood, and other wooden products.

According to the (CDC) Centers for Disease Control, long-term exposure to damp or moldy environments can cause various health problems. Some symptoms include fatigue, wheezing, fever, and asthma development in children.


How Dehumidifiers Free a Space of Moisture

Dehumidifiers come in all different shapes and sizes. Though variations in design and quality exist, most dehumidifiers work the same way. You configure your preferred humidity levels on some models that can be set automatically; when they turn off by themselves when they hit a level higher than you’d like.

The appliance drives the moist air through a cold metal coil, condensing into water. The filtered air comes through a cold metal coil that passes over a warm coil before going back home. It’s easy to empty any collected water in this way!

Choose the Good Dehumidifier for Your Use

 Before deciding on a dehumidifier, it is necessary to take note of some important aspects of the product and your home to determine what size you need, along with the type and efficiency level that will be most appropriate for moisture reduction.

Test for excess moisture

The signs of high humidity in a home can help you determine whether or not you need a dehumidifier to include fogging on the windows and doors and moisture accumulating on walls or ceilings.

 If you are unsure if your house has been experiencing significant moisture issues, buy and monitor a humidity gauge – also known as a hygrometer. This device monitors the indoor air quality and reports the readings to you weekly or monthly via email.

Generally, the humidity levels in a home shouldn’t cause much trouble. But when the air is humid, it becomes difficult to breathe and can make one feel uncomfortable or even ill. When there is too much humidity outside, this should be addressed with a dehumidifier as soon as possible.

Determine the scope of the problem

The scope of the problem will directly dictate the nature of your solution. A larger whole-house dehumidifier would involve a slop sink, sump pump, or direct drainage to outside from an HVAC system. This type of dehumidifier isn’t cheap and is typically not easy for homeowners to install themselves.

What size dehumidifier do I need?

Even dehumidifiers of the same basic design can differ in capacity. Choose a small one that can hold 10 pints of water for a 500-square-foot space, and when you need to add four pants more capacity, you will do so by adding 1 pint at every additional 500 square feet (for example, up to 2 quarts total). So, if your basement is 1000 square feet, then you should choose 14 Pint Dehumidifiers.

If you need to remove extra moisture from the air, it’s best to use a dehumidifier with a bigger capacity. They hold around 12 pints of water for a 500-square-foot space and 5 pints for every additional 500 square feet.


Additional factors before selecting a dehumidifier 

The size of the area where you will place your dehumidifier is a deciding factor when choosing the right product, but there are many other factors in determining what size humidifier to buy or use. Those include household conditions like humidity levels and how different big furnishings inside the home determine them.

Humans produce humid air by breathing and sweating, which produces water vapor. In most homes, the humidity levels are negligible, but if you have a large household of six or more people, then buying a dehumidifier might be necessary to handle increased humidity levels.

The size and number of windows or doors in a home can influence the humidity levels in that space. Windows are good at transferring heat into homes, which leads to higher indoor humidity levels when there is more than one window present. However, large windows do not provide much insulation from outside air, so they have a high potential for elevated interior product temperatures as well.

When deciding what size dehumidifier is right for you, consider the space in which it will be installed and:

  • The number of occupants in your home.
  • Size and number of doors and windows
  • Laundry room and bathroom usage

Prioritize energy efficiency

Dehumidifiers that are Energy Star-rated use about 15 percent less energy than conventional units. In the long run, you’ll save $175 over the life of a dehumidifier – not to mention avoiding roughly 2,800 pounds’ worth of greenhouse gas emissions!

Dehumidifiers provide continuous fresh air during the entire year, resulting in a more energy-efficient solution that keeps mold growth at bay.


Pros and Cons of Dehumidifiers

 Dehumidifiers can be used to provide fresh, dry air in the home and keep mold growth at bay all season long. They are also energy-efficient solutions that help with improving indoor air quality.

One disadvantage to having a dehumidifier is the higher monthly electricity bill. And they also require regular maintenance – emptying the collection bucket, cleaning it out, and replacing its filter, which helps purify your air.

Before bringing a dehumidifier home, it is important to research how loud the one you are considering purchasing would be. It might not need one in your living situation.


  • Reduce allergy symptoms
  • Stop mold, mildew, and dust mites from spawning
  • Protect the home from premature rust and decay


  • Increased electricity consumption
  • Ongoing maintenance requirements
  • Constant background noise

Tip: In some circumstances, a slightly larger dehumidifier than you need may hold advantages. Running it on a lower setting could reduce electricity usage and energy bills; it could also become quieter as well.
