In Singapore’s warm and humid weather, having air conditioning is a must. But here’s a question many people ask: are aircons also dehumidifiers? The quick answer is — yes, aircons can work like dehumidifiers, but they function a little differently.
In this post, we’ll explain how aircons help reduce humidity, how they compare to dedicated dehumidifiers, and when it’s better to use a dehumidifier instead. If you’ve ever wondered whether aircons are also dehumidifiers, or which one suits your home or office best, keep reading — we’ve got the answers for you.
Do Air Conditioners Remove Humidity?
Yes — air conditioners naturally reduce humidity as part of their cooling process. When the aircon cools the warm air, moisture in the air turns into water droplets on the unit’s evaporator coil. Then, this water drains out through a pipe, leaving your room cooler and less humid.
Therefore, if your room feels damp and sticky, switching on the aircon can quickly help lower the moisture in the air.
How Is an Aircon Different from a Dehumidifier?
At first glance, both devices might seem similar because they remove moisture from the air. However, they serve different main purposes. Let’s compare them side by side:
Feature | Air Conditioner | Dehumidifier |
---|---|---|
Main Purpose | Cool the air and lower humidity | Reduce humidity only |
Temperature Effect | Lowers room temperature | Keeps room temperature the same |
Water Collection | Drains water through a pipe | Collects water in a removable tank |
Energy Use | Typically higher | Generally lower |
As you can see, aircons cool the air while lowering humidity, while dehumidifiers focus on removing moisture without changing the room’s temperature.
Which One Do You Need in Singapore?
Now, you might be wondering — which one should you use?
It depends on your needs.
If you want to cool your room and reduce humidity at the same time, an aircon is a great choice. However, if your main concern is removing moisture without making the room too cold, like in a wardrobe, storage area, or basement, then a dehumidifier is a better option.
In addition, many newer aircon models in Singapore come with a “Dry Mode” or “Dehumidifier Mode.” This feature removes excess moisture while using less energy than regular cooling mode. As a result, you stay comfortable without feeling chilly.
Why It’s Important to Control Humidity

Too much humidity indoors can lead to several problems. Here’s why managing it matters:
✔️ It helps prevent mold and mildew
✔️ It reduces musty smells in rooms and cupboards
✔️ It stops dust mites from growing
✔️ It keeps wooden furniture and flooring in good condition
✔️ It improves comfort and prevents skin irritation
Therefore, controlling humidity isn’t just about comfort — it’s about keeping your home clean, healthy, and safe.
