Key Features To Consider Before Buying The Best Dehumidifier
Before you buy a dehumidifier, you should consider the following key features to make sure you get the right one for your space.
Coverage Area & Capacity
A dehumidifier’s capacity is calculated by the pints per day of moisture it can remove from a room. For example, a small machine clearing 20-25 pints per day at 65°F could effectively handle a 400-600 sq. ft. room. A larger room would need a machine with a higher pints per day capacity.
Energy Efficiency & Certifications
Dehumidifiers with energy-saving features are a plus, particularly Energy Star Certified units that have met the strict guidelines established by the Environmental Protection Agency (EPA).
Drainage Options
There are 3 types of drains in dehumidifiers:
- Manual drainage means the machine will automatically shut off when the drainage bucket is full, requiring you to manually empty it.
- Gravity draining means the machine has a drain hose that will automatically drain the condensation. You’ll need a drain lower than the machine so gravity will draw down the moisture.
- A third option is an electric pump to push the excess water from the machine to a nearby drain location. If there isn’t a built-in pump, make sure the pump you choose is compatible with your unit.
Noise Level
If you’ll be using the dehumidifier in a bedroom or other living area, it is advisable to get one with a low decibel level (under 45dB).
Smart Features
Many higher-end machines have smart features like hygrometers that measure the humidity level in the air, app and voice features via phone, and built-in sensors to activate the machine automatically.
Filters & Maintenance
To keep a dehumidifier working properly, the filters need to be maintained. Some machines have filters that can be removed and cleaned to keep the machine working properly, while others require filters to be periodically replaced.

Why You Might Need a Dehumidifier
A dehumidifier can be an essential appliance for maintaining a comfortable and healthy home environment. Its primary function is to reduce the level of moisture in the air. You might need one if you notice signs of excess humidity in your living spaces.
Signs of Excess Humidity At Home
Some common signs of excess humidity in your home are condensation on surfaces, musty odors, visible mold and mildew, wood floors warping, or wallpaper peeling.
Benefits of Using a Dehumidifier
Removing excess moisture from the air with a dehumidifier can help protect belongings from being damaged by dampness, as well as save energy and reduce air conditioning costs. This is particularly useful in damp basements, where a dehumidifier can prevent mold growth and musty odors that might otherwise linger, even near a functioning floor drain.
Health & Structural Risks Of High Humidity
It is well known that high humidity can lead to respiratory ailments [13]. Yet high humidity can also create structural risks in buildings and homes. According to a 2024 article, high humidity is a silent but significant factor in the structural integrity of any building [14].
How To Use and Maintain Your Dehumidifier
Using and maintaining your dehumidifier correctly is key to ensuring it operates at its best and lasts for a long time. By following a few simple steps, you can maximize its efficiency and keep your home’s air healthy.
Ideal Humidity Levels To Aim For
A study showed that the majority of adverse health effects caused by humidity could be greatly reduced by maintaining indoor humidity levels between 40 and 60% [15].
To achieve and maintain this balance, it’s essential to monitor your home’s environment. Humidity control can be easily done with air quality monitors, many of which include a hygrometer to track humidity levels, giving you the information you need to adjust with a dehumidifier.
Placement Tips for Maximum Efficiency
For the best performance, your dehumidifier should be placed in a central location that has good airflow. A hallway or landing would be good, as well as near a moisture center like a bathroom or laundry room.
For a smaller room size or more confined spaces, a mini dehumidifier can be a great option. Make sure the machine has enough space around it for adequate ventilation, and always choose a unit with a capacity appropriate for the square footage of the room you’re treating.
Cleaning the Filter & Water Tank
The water tank of your dehumidifier should be cleaned with warm, soapy water and then treated with a 10% bleach solution to prevent the formation of mildew. This is a crucial maintenance step, much like regularly cleaning the interior of your refrigerator or dishwasher to prevent odors and buildup.
Troubleshooting Common Dehumidifier Issues
These are some things to do consistently to keep your dehumidifier working at maximum efficiency:
- Check the power supply
- Ensure optimum placement for ventilation
- Keep up on cleaning and replacing filters
- Make sure all drain lines are free and unclogged
