Are you tired of bearing the scorching summer temperatures at home? Are you worried that buying an Air conditioner or any other cooling solution for your home will dig a hole in your pocket? Then worry not, these Air coolers are just what you need to relax in your much-deserved leisure time. A quick search on the internet to find an Air cooler to buy will puzzle you with a magnitude of parameters like power consumption, efficiency, climate, humidity control, brand etc and the list goes on. There are hundreds to thousands of air cooler models in the market all the way from room coolers to jumbo coolers used for large area-spaces like an office or a program hall. If you are looking for a small air cooler enough to cool your bedroom, office or anywhere else with a small confined space this article will guide you to finding the best possible match for your requirements.
Ever wonder how an Air cooler works?
Well, it’s really simple. I will explain it in the simplest and easiest way to understand. The majority of the coolers in the market work on the evaporative principle and hence called evaporative/swamp type coolers. On the contrary Air conditioners work using the principle of vapor compression. Getting any ideas?
The air cooler forces the outside warm air to flow over air cooling pads which are wetted by water. As the air flows over the cooling pads it evaporates the water, loosing heat to water and as a result, we have cool air which blows out from an Air cooler. This cycle when repeated multiple types, reduces the mean temperature of the room to a comfortable level. And what’s more? Air coolers are environment-friendly – they don’t utilize electricity and harmful gasses which can contribute to Global warming.
What should I consider before I buy one?
I have listed some of the factors which you should take into account before you make your decision.
- Choose the right capacity as per the size of your room. More on that below.
- The height of your ceiling!
- Portability: Do you need to move your air cooler very often?
- Quality and value for money
- Does the fan make too much noise?
- Does it have a remote for easy of access?
- How many liters of water can it store?
Look for CFH(Cubic Foot per hour), a parameter to measure the rate of airflow. To explain in simple terms the bigger your room, the more the flow rate(CFH) has to be for effective cooling. We have created a calculator to make the task of finding the suitable CFM for you.
Simply enter the area and height of your room and we will handle the rest.
(Field to enter area and height here)
By now you must know the flow rate that you need for your room. Let’s move on to the next parameter.
The height of your ceiling:
This is self-explanatory. You don’t want to buy a cooler only to find that it doesn’t fit in your room because it is taller than your roof.
A cooler operates at different efficiencies based on the climate. It works by using the principle of evaporation. The greater the water evaporation the better the cooling achieved. However, there is a limit to the amount of water the air can hold. In coastal areas, the air is already humid (contains water) and hence a cooler would not be able to evaporate as much water. Air coolers were designed to be used in hot and dry climates, in the recent year’s companies have come up with an innovative measure called humidity control. By utilizing this feature you can use a cooler even if you are in a coastal area. So if you live in such an area, be on the lookout for this feature. Although air coolers are not as effective in hot and humid regions they are still widely used because of the low cost.
An air cooler consumes only about 1/8th of the power that an Air-conditioner sucks in. I don’t want to bore you with the specifics. You can save plenty on electricity bills and at the same time be eco-friendly.
Type of cooling pads:
Two types of pads are commonly used- Aspen and honeycomb. Honeycomb pads absorb more water than Aspen pads and contribute to more evaporation resulting in better cooling.
Aspen pad: 72% efficiency
Honeycomb pad: 84% efficiency
Fiber body vs Galvanized metal body:
A fiber body gives a more pleasing and aesthetic looking. The downside is lower efficiency because this limits the area of the cooling pads.
Galvanized steel bodies are more robust and may seem less aesthetic to most. But the key advantage is higher efficiency and longer life of the machine. The galvanized metal will prevent rusting if you are worried about rusting.
With this knowledge, you should be equipped to make the best choice.

1.1 Symphony Diet 12T:

We believe the Symphony 12T air cooler provides the most value for money and quality and it can be rightly called the best cooler in India. As the name suggests, it has a water capacity of 12 liters, three-speed settings. A honeycomb pad is used which gives it an upper hand over most other coolers in the efficiency segment. It has a cooling coverage area of 100 sq.ft which should be adequate for a small bedroom or office.

For those of you thinking “wait a minute, what about all those negative reviews on Amazon”. Do people really expect to get the cooling effect of an Air-conditioner with an Air cooler? Seriously, you can’t expect a 5000-6000Rs product with a 25000rs product. It doesn’t make sense .Let’s get real. Having said this, I want to make it clear that Symphony has a bad reputation for customer service. So you may want to consider this aspect before you buy it.
