7 Easy And Effective Ways To Reduce Humidity From Air Cooler

Last Updated on 14 May, 2024 by Sourav Roy

A good air cooler can be an excellent companion during summer. It can lower the temperature of a room by several degrees and make it more comfortable to stay in. However, one problem that air coolers can cause is increased humidity in the air. This can be particularly troublesome in areas with high humidity levels already.

Easy And Effective Ways To Reduce Humidity From Air Cooler

Fortunately, you can do a few things to keep the air dry. In this post, I’ll tell you how to reduce humidity from air cooler.


Why Do Air Coolers Produce Humid Air?

Before we begin, let’s get this out of the way first. You’ll be able to better use the tips I have if you know why exactly Air Coolers tend to make the air so humid.

Air coolers work by evaporative cooling. This is the same principle that your body uses to cool itself down on a hot day. When you sweat, the water on your skin evaporates and takes some heat with it. This is called the latent heat of vaporization, and it’s what makes evaporative cooling so effective.

Air coolers use the same process. They have a water reservoir that they use to wet the evaporative pads. These pads are usually made out of thick, absorbent material like cellulose or honeycomb. As the fan draws air through these pads, the water evaporates and cools the air.

The problem is that this process also releases water vapour into the air. And this is what increases the humidity in your home.

7 Tricks To Reduce Humidity From Air Cooler

Tricks To Reduce Humidity From Air Cooler

Here are the best ways to make the air in your room drier. I’ve experimented with all these methods- they can make your room significantly more comfortable.

1. Ensure Proper Ventilation

Ensure Proper Ventilation

Cross ventilation is the most basic and easiest solution. You can do this by opening doors and windows on opposite sides of the room. As a result, dry air from outside will come in and get rid of a significant amount of humidity. However, do note that you might not get as much of a benefit from that if you’re living in a coastal area, as the outside air is also bound to be humid.


2. Use Charcoal Briquettes

Use Charcoal Briquettes

Charcoal is a great way to reduce humidity in the air. It can adsorb a large amount of water vapour, and it’s very effective in small spaces. You can buy charcoal briquettes from most stores, and they’re really easy to use. Just place them in a bowl near the air cooler and let them do their job. They’ll be able to absorb a good amount of humidity as long as there’s no extra obstruction or covering. However, you also need to be cautious while using this method; charcoal is easily flammable, so you might set off a huge fire if you place it in the wrong area.

3. Fix Leaks Around The House

Leaks in any plumbing inside your home

Leaks in any plumbing inside your home can lead to a rise in indoor humidity. This is because water coming out from these leaks will evaporate and add to the already existing amount of water vapour in the air whenever the day is particularly hot. By fixing the leaks, you prevent any more extra water vapours from being added to the air. If you can’t do the task yourself, just call a plumber.


4. Don’t Hang Laundry In The Room

Don't Hang Laundry In The Room

Leaving wet clothes hanging anywhere in the room can lead to an increase in its humidity levels. The effect is even more apparent when you leave them in front of a cooler; doing so won’t help dry clothes faster at all. Clothes need dry air to get dry, which isn’t something a fan of an air cooler provides. It’ll simply make more mist instead, making your clothes even more soaked. So when drying clothes, always make sure to do it outside or on a balcony.


5. Get Rid Of Any Plants In Your Room

Get Rid Of Any Plants In Your Room

You might be surprised to know this, but plants actually add to the humidity levels in a room. This is because they release water vapour into the air as part of photosynthesis. So if you want to reduce the humidity in your room, it’s best to get rid of any plants you have there. You can replant them outdoors or keep them on a closed-off balcony to keep any released vapours from entering the room.


6. Load Ice Into The Air Cooler

Load Ice Into The Air Cooler

An effective way to make the air in your room drier is by loading the cooler with ice. Once you do that, the cooler will start blowing out cooler and drier air, which will help reduce the overall humidity in the room. Just be careful of putting in too much ice- it’ll hamper the evaporation process instead.


7. Maintain The Cooler

Maintain The Cooler

If you don’t maintain your cooler properly, water can start to accumulate inside it. This will, in turn, lead to the cooler releasing more moisture into the air and making the problem even worse. To avoid this, make sure to clean out the water reservoir and pads regularly.
