Air Coolers: How to Choose the Right Size for Your Room
Iraq's summer heat is hot and dry — exactly the conditions where an air cooler works well. It cools the air with water instead of a refrigerant, so it uses far less electricity than an air conditioner. But an air cooler that is too small for the room will struggle, and one that is too big wastes water and space. This guide explains how to match the cooler to your room.
How an air cooler works
A pump keeps honeycomb cooling pads wet with water from the tank. A fan pulls warm air through the wet pads, the water evaporates and cools the air, and the cooler blows fresh, cool air into the room. Most MODEX air coolers are 2-in-1, so you can also use them as a fan without water.
1. Measure your room
Multiply the room's length × width × height to get its volume in cubic metres. For example, a room 4m long, 5m wide and 3m high is 60m³. Compare this with the cooler's cooling capacity or airflow.
2. Airflow (m³/h): how much air it moves
Airflow is how much air the cooler pushes out every hour. The bigger the room, the more airflow you need to cool all of it, not only the spot in front of the cooler.
3. Water tank: how long it cools
A bigger tank runs longer between refills. Coolers use more water on higher speeds, so a large tank is important for big rooms and long summer days.
4. Handy features
- Low-water alarm and auto-off: protects the pump when the tank runs dry.
- Remote control and timer: change settings and switch off at night without getting up.
- Memory restart: the cooler switches back on with your settings after a power cut.
- Castors: move the cooler easily from room to room.

Frequently asked questions
Does an air cooler work in Iraq's summer?
Yes. Air coolers work best in hot, dry air, which is typical of an Iraqi summer. They cool the air by evaporating water.
Should I keep a window open?
A little fresh air helps. Opening a window or door slightly lets humid air out so the cooler keeps cooling well.
How often do I need to refill the tank?
It depends on the tank size and speed. For example, the AC996 uses 0.8–1.6L per hour, so its 20L tank lasts many hours. The AC998 uses 1.8–5.5L per hour with a 45L tank.
What happens if the water runs out?
MODEX air coolers have water shortage protection that switches off the cooling automatically.
