A dehumidifier uses a fan to draw moist room air over a series of coils - first a refrigerated coil, and then a heated coil. As the refrigerated coil cools down the moist air, the moisture content in the air condenses into water and drips down into a collection bucket or drain hose. The now drier air then passes over the heated coil before being released back into the room as dry, warm air. A dehumidifier is most effective at warmer temperatures and higher relative humidity levels.
Many basements in warm humid climates need dehumidification during the summer months to keep mold growth at bay. If you notice a musty smell or odor in a room, it will probably benefit from a dehumidifier, as drier air is not only healthier for you but will also be less likely to smell or have a stale, musty odor.
A quick and inexpensive way to check the relative humidity level in any room is with a hygrometer. Dehumidifiers are rated according to pint capacity, which refers to how many pints of water it is capable of removing from the air in a 24 hour period actual water removal per day will vary with the temperature and relative humidity level of the room.
Most dehumidifier manufacturers do not refer to specific room sizes in square feet, as the starting relative humidity level of the room plays just as important a role as the size of the room in determining the capacity needed. Dehumidifiers range in capacity from 25 to 70 pints per day the higher the capacity, the more moisture it is capable of removing per day. Generally you want to use the highest capacity dehumidifier possible in your room to ensure the most efficient operation, as a higher capacity unit will be able to extract moisture from the air faster and as a result may not need to be run as frequently or on as high a fan speed as a lower capacity model.
If you have a small area and space is a concern, then of course the lower capacity models are an excellent alternative. How much electricity does a dehumidifier use?
Electricity usage varies with the capacity of the dehumidifier. While a higher capacity dehumidifier will draw more electricity while running, the larger units are actually going to be more energy efficient because they are more effective and faster at removing moisture from the air. This means that the larger the unit, the less often the compressor will need to be on, thus saving you money in the long run.
How often will I need to empty the water bucket, and can I have the dehumidifier drain continuously? Dehumidifiers come in many shapes and sizes. Refrigerant dehumidifiers work by condensing moisture in the air into water with the help of cold evaporator coils. This type is considered the industry standard for homeowners because it works well at room temperature.
Another option is a desiccant dehumidifier, which draws air through a chamber that contains water-absorbing gel packs. These are usually quieter than the other option and draw less power to get the job done. Another way to reduce moisture downstairs is to install basement fans to control humidity. Similar in function to a bathroom fan, these high-capacity vents push moist air away from the basement and into the outside air.
If used sparingly, you can also run your bathroom fans to reduce humidity in the house. Putting a dehumidifier in the dampest part of your basement can dramatically reduce its humidity levels. A dehumidifier has a fan that draws in air — that air then runs into cooled coils that remove its moisture and deposit it in an attached tank or down a drain.
Make sure to check and empty the reservoir regularly, or talk to a plumber about having your dehumidifier attached to a floor drain. If your basement has windows, consider cracking them open when temperatures are cooler outside than inside to help get rid of some of the humidity.
Basement bathrooms can produce a lot of humidity, too. Consider making your house a smart home by installing a smart hygrometer, thermostat and other home appliances that can help you keep your home safe and comfortable with just a couple taps on your phone.

There is no perfect humidity setting level. But there is a range of what the right humidity level is. We want it to be in that range. A dehumidifier can help dry out the air. It is not important to get the humidity just right. Many dehumidifiers can tell you the humidity level in a room. If you do not want to use the humidity levels on your dehumidifier, then you may need to adjust it up or down. Your dehumidifier has a button to control the humidity. If you have an older dehumidifier, you might need to experiment with the settings.
