Indian middle class summers are incomplete without an air cooler. Not just the middle class but the economic energy consumption and its budget pricing make the air cooler an attractive option to almost everybody.
The quality of an air cooler is primarily dependent on 3 major factors. They are
- Tank capacity: The capacity of an air cooler to store water to provide cooling divides it into two types. A personal cooler and a desert cooler. If you need a cooler for a big family or a big room, go with a desert cooler. If you need it just for yourselves or your partner as well in a small bedroom, go with a personal cooler.
- CFM: This is the Cubic feet of Air thrown per minute. This decides how powerful your cooler is. Ideal CFM ranges from 2500 to evben 4500 m3/hour as well. More people needs much more CFM
- Cooling Medium: This is the grass that comes on the sides of the cooler. There are generally two types of grass. The honeycomb and the wood wool. Wood wool is the commonly available and is good enough for most coolers. If you are very particular about water consumption, go with a honeycomb medium.
While those three were the three important features, there are many more additional features such as swing, pump, wheels, remote control etc., We have included all about these in the Buying guide section of the article. Make sure that you give that a read as well.
Now, let us jump right into the list of the top coolers available in India, for 2019.

The quality of an air cooler is dependent on several factors. But before you look at those factors, you first need to decide on the type of air cooler you are buying.
1. Types of Air Coolers
There are only 2 different types of air coolers available in the market now that are categorized based on the functionalities.
- Personal Air Cooler or Room Air Cooler
- Desert Air Cooler
Personal Air Cooler
Personal air coolers or room air coolers are made for one or two persons in a single room (mostly small to mid-sized bedrooms). They are small, compact and cool a room using blowers.
Also, personal air coolers have smaller tanks compared to that of a desert cooler. A personal cooler may have a 20 litres storage compared to the massive 85-90 litre storage tank of a desert cooler.
While that stays, Personal air coolers are very economical and effective against humid areas. If you are a bachelor or a small family or someone who has a very small humid bedroom, go for a Personal Air Cooler.
Desert Air Cooler
Desert Air Coolers are bigger machines that are designed for bigger and spacious rooms. Typically placed outside the window, these coolers take air from outside, cool them down through trickling water and then throw them into the room.
While the cool air comes into the room, the hot air from inside will be let out and thus maintaining the temperature of the room.
But as is the case, these types of coolers are more expensive compared to a personal cooler but they have an additional advantage of storage capacity.
As mentioned before, Desert Air Coolers come with very large tanks of 40-90 litres capacity. Thus no need for hasty refillings like you have with a personal cooler.
For a personal cooler, you might need to refill the tank about 3-5 times in a day but for a desert cooler, you just need to fill it once or maybe twice for a whole day.
Given below table completely explains the 2 different air coolers by considering the features like tank capacity, air circulation and room types that have the same functionalities.
|Feature||Room Air Cooler||Desert Air Cooler|
|Tank Capacity||20-30 litres||30-90 litres|
|Air circulation||Blowers||Huge fans|
2. Size of Room and Air Cooler
Size is one of the foremost important factors that you should consider while purchasing air coolers. After deciding on what type of cooler you are going to buy, you need to assess where you are going to use this. Do you have a large room or a small room to be cooler?
CFM (Cubic Feet per Metre) is a metric that decides the air delivery rate to the room. This is calculated depending on the size of your room.
CFM (in hours) = (room Surface area in Sq.ft*height*0.84)
For instance, consider a room of size 100 Sq.ft along with a ceiling height of 10 feet. Thus the total room will be considered as 1000 cubic feet (100*10).
Now, the CFM will be half of the cubic feet which are 500 (1000/2).
Room size=100 square feet
Ceiling height= 10 feet
Total=100*10=1000 cubic feet
CFM=cubic feet/2 =1000/2=500.
The chart below gives you a brief idea of how each sized room has its tank requirements.
|Size of the room||Size in Feet||Cooler tank capacity|
|Small||12 x 14||20-30 liters|
|Medium||14 x 20||30-60 liters|
|Large||16 x 24 or higher||60+ litres|
Also, check the product description thoroughly to compare the room size with the air cooler.
3. Cooling pads/ Cooler Grass
Cooling pads (or) Cooler Grass are the boards that come on either side of the cooler and it’s back. They are made out of jute, fibre or other materials which will provide a cooling effect when they soaked in water and are placed near the fan.
When the fast air comes out of the cooler, it touches these pads and evaporates the water on them. These molecules will jump onto the air and cool them down giving you cool air.
There are just 2 types of cooling pads available in the market.
- Honeycomb cooling pads
- Wood wool cooling pads
Honeycomb cooling pads are made in complex honeycomb-like arrangement and jute materials. They have a tendency to retain more water and thus honeycomb pads have a better cooling effect.
A wood wool cooling pad cannot hold a lot of water but are affordable and cheap. So if you live in very hot and humid areas, it is better that you invest some money and buy a honeycomb cooling pad cooler.
But if you are living in areas where it is not too much hot in summers (mostly towards higher altitudes with bearable summers), then save money by buying a wood wool cooling pad.
Even if you are going for a desert cooler, then pick a wood wool one. This is because the speed at which a desert cooler works, the cooling pad type does not really matter that much.
First off, tank capacity is primarily dependent on the size of the room you are placing it in. But again, the tank capacity can also be decided on how long you are going to leave the cooler on for. For instance, you may have a small room but you may leave the cooler on for a whole day which will require a lot of water.
In such cases, you even though the required CFM is higher, you need to go ahead with a desert cooler with higher tank capacity.
5. Power consumption
The best part about owning and using an air cooler is that they do not consume a lot of power. Typically, an air cooler may consume power ranging from 90-200Watts.
Apart from that, modern coolers also come with a lot of smart additions and even inverters too. Depending on what functions your cooler has, your wattage may change.
The rule of thumb is that low priced air coolers have lower wattage compared to that of high priced coolers. But by common sense, the units of power burned by coolers may not have a heavy impact on your electricity bill. Hence do not worry if you have to pick a feature-rich cooler with 200-watt power consumption.
6. Some Other factors to consider
Given below are some of the amazing features that you should keep in mind when you wish to purchase the air coolers online.
- Cooling Pad thickness – The thickness of the cooling pad plays an important role in the air-cooling operation. The pads need to have a minimum thickness of 90mm which will be effective in retaining the moisture and providing enough cooling effect.
- Blower speed – All coolers have a blower speed control. This knob gives you control over how speed the fan would be going. Typically, you will be having 3 speeds. Low, Medium and High. But ideally, the knob can go as high as 7 also. Higher the speeding options, the better you can control the wind from the cooler.
- Electronic thermostats – Some of the high-end coolers come with electronic thermostats which will monitor the temperature of the room/cooler and change the speed of the fan, switch the pump on/off automatically.
- Water level controller – Water level controller features are mostly seen in almost all modern air coolers. The automatic water level controllers ensure whether the water is filled up to the pre-set levels and stop flooding. When the water in the tank reaches the pre-set levels, either it alarms or buzzes and stops flowing of water. For optimum functioning of the air cooler, it controls the inlet pipe of the cooler flowing water into it.
- Water level indicator – An important and very common feature, water level indicators are either level based or just semi-transparent plastic on the cooler frames. A level-based indicator gives you an idea of when you can refill the tank.
- Automatic shutoff dampers – An unusual feature, automatic shutoff dampers are the flaps present in the cooler. It discharges the fan to reduce the loss of cooling from the cooler. They usually present in the duct to open up when the fan starts and shuts when the fan stops.
- Remote control – Many modern coolers also come with remote control. Though available for high-end models, remotes let you control the pump, speed of fan and swing.
- Casters – Caster is a just a wheel mounted on a device to ensure the free movement of an object. Not all types of coolers come with casters. Travel-friendly and lightweight coolers come with castors whereas heavy desert coolers do not come with casters.
Check whether the air coolers you buy have caster wheels or not. If this isn’t included along with the cooler and you need the cooler to move about, then you need to invest a little in casters which allow the air coolers to move freely from one position to another.
- Timer – Some coolers come with a timer equipped with them through which you can set shut off time. More of an additional feature, it makes your sleep at night convenient.
- Ice cube tray – The output of the cooler is as cool as the water you pour in. There are many coolers which come with a separate compartment where you can place ice. Such ice cube trays melt down the ice and it adds up to the water to add to the cooling effect.
- Air cooler without water – These are not technically full-fledged air coolers but are lightweight mini coolers which do not have a tank. They have smooth casters which make it easier for you to move it about from one room or place to another. Ideal for bachelors, they often are priced very low but do not guarantee cool air like a water air cooler.
Frequently Asked Questions
1. How to run air cooler on the inverter?
There are no special separate settings for air coolers to run on an inverter. As they are low energy consuming appliances, if your inverter has the required, you can directly plug it in and it will work normally.
There are however inverter air coolers that come with special inverter settings. When there is a power cut, by switching it on, it balances and works on the house based inverter and protects the cooler from voltage fluctuations.
2. What is the use of honeycomb pads in air cooler?
When the warm air is drawn into the air cooler, it passes through the honeycomb cooling media. Compared to the wood wool media, a honeycomb structure facilitates greater water absorption. This leads to more water getting evaporated and thus provides better cooling.
3. Do air coolers require a lot of electricity to run?
No, an air cooler doesn’t require a lot of energy. Running an air cooler requires less electricity compared to the air conditioners. Of all the air coolers Honeywell air cooler consumes very less power, making an attractive cooling medium where the electricity cost is too high. The average power consumption of Honeywell air cooler is 193Watts.
4. Why does a desert cooler cool better on a hot dry day?
The desert cooler cools much better on a hot dry day than other days, because of the temperature which is too high and the less humidity. Both of them help in having a high-evaporation rate that gives a better cooling effect.
5. How does an evaporative air cooler work?
Evaporative air cooler uses evaporation mechanism to cool the air. The operation is such that when the pump circulates water from the tank to a cooling pad, it becomes wet. The fans draw outside through the cooling pads and when it does, the air is cooled by evaporation.
The key factor to cool the device effectively is to ensure the cooling pads completely saturated at the time and the motors, fans are designed to deliver high air-flow.
6. How waterless air cooler works?
Waterless air coolers are basically normal table fan type mini air coolers. They do not have any tank to store water so they take in air from large spaces and then push it through the fan to a small area. The difference in airflow will create the required coolness.
7. Will air cooler cause asthma or rheumatism?
Not exactly. If you are already suffering from asthma, rheumatism or any other breathing ailment, then it is suggested that you sleep at a certain distance from the air cooler.
Breathing cool air at night times in an air-conditioned bedroom may cause loss of heat from airways that are important for triggering exercise-induced asthma. It also encounters with rheumatism where there is a maximized usage of cooling devices at homes.
8. Do air coolers require a lot of electricity to run?
No, an air cooler doesn’t require a lot of energy. Running an air cooler requires less electricity compared to the air conditioners. Because the cooling fans connected to the motors utilizes less power and handles it very smoothly thereby generating coolness in a room.
Given the humid nature of Indian summers, it is ideal that you pick an air cooler with a very high tank capacity. The Crompton Ozone air cooler comes with a massive 75 litres of water tank capacity. This can serve a large room of 550 square feet and has a large CFM of 4600 m3/ hour and an impressive 52 feet air throw. It has a honeycomb cooling medium and seperate ice cube tray. All this for a very low energy consumption and a 1 year warranty makes it a best buy out of all mentioned in the list today.
