5 Best Dehumidifiers of 2025

Dehumidifiers remove moisture from the air to prevent mold, mildew, musty odors, and condensation in damp areas of your home. They work by pulling air over cold coils, condensing the water vapor, and releasing dry air while collecting water in a tray.

Humans need some humidity for comfort, but too much is problematic. Low humidity can cause issues like chapped lips and cracked wood, while high humidity encourages mold and mildew growth. A dehumidifier helps manage excess moisture effectively.

How Dehumidifiers Work？

Imagine drinking a soda on a hot day. You might notice the can feels wet on the outside. Why is that? As the air cools, it can’t hold as much moisture, so the colder surface of the can pulls water from the warmer air, forming condensation. A dehumidifier works the same way. Most dehumidifiers have five main parts:

Fan Compressor: Compresses and expands a refrigerant like freon to cool the coils. (For details, see How Air Conditioners Work.)
Reheater: Captures the heat produced during the cooling process.
Cooling Coils
Reservoir

How do these parts work together to remove moisture from the air? It’s simple and effective:

1. The fan pulls in air from the surrounding area.
2. The air passes over the cooled coils, which cause moisture to condense and drip into the reservoir.
3. The air is reheated and released back into the room.

What’s the Difference：Air Conditioner vs Dehumidifier

Air conditioners and dehumidifiers function similarly: both use refrigerant, evaporator coils, and condensers to remove moisture from the air. However, while air conditioners cool the air, dehumidifiers do not.

This is because a standard dehumidifier is not designed to expel hot air from the home. It only cools the air enough to extract moisture and then releases warm air back into the room.

The primary purpose of a dehumidifier is to remove as much moisture as possible from the air. It does this by drawing moist air over cold coils, which causes the moisture in the air to condense and turn from water vapor into liquid water.

The dehumidifier collects this water in a bucket or tray. This collection pan can be easily removed and emptied manually from time to time.

Dehumidifier Features and functionalities

You’ve chosen a dehumidifier that’s the right size and energy efficient. Now, it’s time to look at the details. Dehumidifiers come with several features you should be familiar with. If you think you’ll need any of these features, make sure to select a model that offers them.

1. Mobility – Most people want to move their dehumidifier around, so if it’s a large unit (more than 8L), ensure it has a handle and caster wheels.
2. Adjustable Humidistat – Allows you to set your preferred humidity level.
3. Inbuilt Hygrometer – Automatically detects the air’s humidity and helps the unit decide when to turn on or off.
4. Automatic Shutoff – Shuts off the unit when the ideal humidity level is reached or the water tank is full.
5. Auto-Reset – If there’s a power outage or you unplug it, the system remembers your settings for next use.
6. Defrost Mode – Prevents the dehumidifier from freezing in low temperatures.
7. Noise Level – Dehumidifiers come with a noise rating so you can know how loud they are during operation.
8. Continuous Drainage – Some dehumidifiers include a built-in hose for draining the water tank, so you don’t have to empty it manually.

For example, if you won’t be around to turn off the dehumidifier, an automatic shutoff feature is essential. Likewise, if you need it to run while you’re away, such as in a basement, choose a model with continuous drainage.
