10 Best Air Coolers in India 2021 ( Review Features & Suggestions )

Buying Guide of Air Coolers

Before buying an air cooler, you have to keep some factors in mind, which will help you to find the right product according to your needs. Most importantly, doing so will save you both money and time.

How does an air cooler work?

Air coolers work on the evaporation method. The outside air is drawn inside the cooler, then the moisture on the cooling pads evaporates by absorbing the heat of the air. Due to which the air becomes cold, then the fan throws the cold air into the room, and in a short time, the temperature of the room decreases.

Water on the cooling pads is circulated by the water pump. Cooling pads only work to cool the air, without it the cooler is just a fan of air.

• Type of Air Cooler

Air coolers are of three types – tower, room, and desert air cooler. The working principle of the three types is the same and there are differences in water tank capacity, cooling capacity, and features.

See, all three coolers are used according to different room sizes. Read the below-given definitions.

1. Room air cooler

Room air coolers are also called personal air coolers. They are used for small rooms whose area is 100 to 300 square feet. And they are small and lightweight.

Room coolers are suitable for working in humid areas. Water tank capacity is in the range of 20 to 30 liters, which is much less than Desert Coolers, due to which their size and weight are less.

Small size and low weight allow them to be kept and used easily anywhere. You can keep them in places like the bedroom, kitchen, hostel room, and a small shop and avoid the heat.

If you are a hostel or run a small shop, then room coolers are the best option for you. But if the area is larger then find another option. They have a blower fitted which throws air.

2. Desert Air Coolers

Desert air coolers are meant for large size halls, shops, malls, and restaurants as they are capable of extreme cooling. The capacity of water tanks can be between 30 to 60 liters, it depends on your need.

They are larger and more expensive than room coolers as well as they have excellent power to cool well. If the size of your hall is more than 300 square feet, then you should go for Desert Coolers. There is a fan in it, which throws air into every corner, which reduces the temperature of the hall.

For the Indian climate, it is better than the air conditioner because it works efficiently in the dry climate. The best place to keep these coolers is right in front of the window if you want 100% better cooling.

Nowadays, Desert Coolers are equipped with all kinds of digital features such as humidity control, speed control, ice chamber, and many more which make them convenient and effective.

Factors to consider while buying an Air cooler

Below are some important factors that you must consider before buying any air cooler. These will help you to buy the best and the perfect cooler according to the need.

1. Water tank capacity

The higher the water tank capacity, the less the hassle of refilling the tank. Choose a cooler that is capable of cooling you for as long as you want.

The larger the water tank is, the larger the size of the cooler is, so if you want a cooler for a small room, then take the decision by keeping the size of the water tank in mind.

2. Area coverage

All coolers have a term in the description called “area covered” which describes how much area this particular cooler can cool in the best way. There are desert air coolers for large size halls and room/tower air coolers for the small or medium size.

So before buying a cooler, calculate the area of your room and select a cooler whose area is equal to or more than the calculated value. With this, you will be able to choose the right cooler which will give you great coolness in summer.

3. Cooling pads

Cooling pads are the only ones that convert hot air into the cold air, and then the fan spreads the cold air everywhere, so it is important to choose a good cooling pad.

Good cooling pads have high water retention ability so that maximum water evaporates by absorbing heat from the air. Two types of cooling pads are available – Honeycomb and Wooden Wool Cooling Pads.

Honeycomb cooling pads are more durable, effective. They do not need to be changed for 2-3 seasons and their structure is like a house of bees, due to which they can retain more water.

At the same time, wooden wool cooling pads are less reliable, effective, and durable. They may have to change 2-3 times in the same season.

4. Power consumption

It is always good to buy a cooler that consumes less power while providing better cooling. Therefore, when buying a cooler, check the power consumption. Coolers with power consumption from 150 to 220 watts consume less power.

5. Castor wheels

Castor wheels make it very easy to move the cooler here and there, you do not have to do much physical work. So it is a good idea to buy an air cooler with a castor wheel when you have a heavy cooler.

Now Castor Wheels also come in different types – Castor Wheels made of plastic deteriorate after some time of use. And the wheels made of thick rubber and metal last for a long time.

Nowadays, coolers with detachable castor wheels come, so that the coolers can be used differently.

6. Water level indicator

This feature tells you the level of water present in the water tank, which will save you from overfilling the tank, and tells you before the water in the tank is exhausted.

Some coolers have an electric indicator that points digitally. It depends on your budget which option you will go for.

7. Speed control feature

The coolers mostly have three-level speed control and by changing the level you can manage the cooling intensity according to your requirement.

There are high, medium, and low speed controls that provide cooling from different intensities. This feature is most useful for pregnant ladies or newborn babies, as they cannot be kept in front of the cooler’s fast air.

8. Empty Tank Alarm

This feature gives you a voice signal before the water runs out in the tank so that you can refill the tank. When the cooler is running, it is necessary to have water in the tank as the temperature in the room increases, and the chances of motor damage also increase.

This feature is more important in Desert Coolers. Tower/room coolers do not face any problem in using without water so this feature is not of much use.

9. Remote Control Feature

Nowadays the new generation wants control of everything in their hands, so why not the air cooler. With the remote control, you can control all the features and modes of the cooler sitting away from the hands.

Fully functioning remote can control any feature such as speed control, lowers, and other modes.

10. Ice cube chamber

The Ice Cube Chamber allows you to pour ice and give chilled and fast cooling. After placing some ice cube in the ice chamber, the ice melts and gets into the water tank, which causes the temperature of the room to decrease quickly.

But by putting too much ice, it will not make the room too cold, it will give an effective experience only to people sitting for some distance.

11. Inverter compatibility

This option is not necessary for everyone, only for those whose house is in an area or city where power is cut off. If the cooler is inverter compatible, it is written in the cooler description.

12. Brand

If any product is of a good brand, then it can be trusted, and it is also in air coolers. Good brands will survey you even after buying coolers like repairing. Brands like Symphony, Bajaj, Kenstar, and Crompton supply good coolers to the entire world.

13. Warranty

The longer the warranty period, the more trust. Buy a cooler with a longer warranty period. If your cooler is damaged in the warranty period, then the company repairs it for free, so do not forget to check the warranty period.

14. Correct Price

Although the price of the best air coolers is not high, you should still know the correct price of the right cooler. Powerful and popular brand air coolers are priced between Rs.6000 and Rs.11000. And if your need is for more area then you will have to pay a little more amount.

15. Humidity Control

Air coolers do not work properly in places with high humidity because coolers work on the evaporation process. The more water evaporates by absorbing heat from the air, the colder it is.

If there is already enough water in the air, then it will not be able to hold more water, because of this, coolers are lost here.

Some big brands are introducing features like “humidity control” to get rid of this problem. This feature makes air coolers to be used in humid areas.

16. Perfect Size

It is of no use to buy large-sized coolers that encircle the entire space of the room. Nowadays companies are bringing air coolers of luxurious designs and perfect size, which enhances the beauty of the house with good performance.

Advantages of Air Coolers

1. Economical: For the common man, air coolers are the cheapest way to stay comfortable in the summer as they are 80% cheaper than air conditioners. maintenance, repairing, and parts cost is also cheaper than AC.

2. Power consumption: Air coolers consume very less power, almost 70% less than AC. Because in the coolers, electricity is used to operate 2 motors. Coolers consume 40% more power than ceiling fans.

3. No Harmful Gases: Air coolers use water for cooling, it is a natural method. In air conditioners, many powerful gases are used, which is not good for both health and the environment. Gases emitting from the AC affect the ozone layer, which causes the sun’s powerful ultraviolet rays to reach us and cause diseases.

4. Convenient: You can move air coolers from one room to another whenever you want, which you cannot do in air conditioners. A feature like Castor Wheels makes this easier to do.

5. Fresh and Healthy: Here also the air coolers are ahead of the AC’s because the air conditioners circulate the air inside the room frequently to cool. While the coolers continuously bring the fresh air inside from outside to cool, which is a fresh and healthy way.

6. Parts availability: air cooler parts such as body, honeycomb cooling pads, water pumps, wires, etc. They are easily found in the market and also cheap. Indian companies supply coolers all over the world, due to which parts in India are found cheap.

Disadvantages of air coolers

1. Climate: Air coolers are not efficient in humid areas, so they are not used much in western countries. The climate in India is hot and dry due to which coolers are the first choice of the people here. At the same time, air conditioners can be used effectively in any climate.

2. Water supply: Coolers cannot cool without water, so continuous water supply is necessary. While air conditioners run without water. In coolers, water has to be filled 1 to 2 times every day for continuous cooling, however, it depends on the water tank capacity.

3. Frustrated sound: Yes, if you have not bought a cooler of the right quality, it will create an irritating noise. It is also caused by loose and faulty parts. This problem does not occur in air conditioners that make you feel peaceful sleeping.

4. Weight: Desert coolers come more weight and bigger size, so it is not so easy to take them anywhere. Due to the castor wheels, this can be done easily but lifting is difficult. At the same time, AC’s are mounted on the wall, they cannot be shifted freely.

5. Effective: Coolers do not cool so well compared to air conditioners but they are healthy. The temperature of the room comes down slowly while AC makes it work quickly.

Tips to increase the efficiency of air coolers

If you take care of some special and simple things, then you can increase the efficiency of the coolers more. So let’s read about those tips.

1. Positioning: The best place to position the air cooler is in front of the window. By absorbing the heat of external hot air, water evaporates quickly. The more evaporation, the colder it is.

2. Cross-ventilation: By keeping some of the windows of the room open, the circulation of air goes on continuously, so that fresh air keeps coming in.

3. Use Ice Chamber: Due to the chilled water, the temperature of the room decreases rapidly, but by putting too much ice, the evaporation rate is reduced, which does not make the cooler more effective.

4. Quality cooling pads: Good cooling pads, of course, increase the efficiency of air coolers and their timely cleaning is also important. Water retention efficiency increases when cooling pads are taken care of. The more water the pads can hold, the better they will be.

5. Cleaning of fans: Due to the continuous movement of the fans, dirt gets collected and efficiency is reduced. So take care of the timely cleaning of the fans.
