Top 3 Best Air Cooler in India 2021

Air- Coolers


When you talk about air coolers you are talking about something which has a history of may be over thousand years.  People have been capitalizing on this idea in different forms for many years. They look much contemporary now, but the basic mechanism of working is quite same as before.

Premature Air-Cooling:

Evaporative cooling takes place when water evaporates into the air, after this the heat in the air is disoriented. Evaporative cooling happens in nature quite often over oceans or lakes anywhere where there is water. We have been exercising this natural procedure to beat the heat since ages.

We can track its roots from ancient Egypt, from around 2500BC- where the engraving on the walls show the images of bondservant stir up bowls of full water to keep their kings cool. The Egyptians draft their homes in such a way that they can absorb water from their ponds.

The Invention of the Air Cooler:

Hot countries carry on with these ancient evaporative coolers for ages. Roman emperors use to go into the mountains and bring down ice to keep their homes cool. In 16th century the first air cooler was invented.

That entire air cooler wanted was some running water to work and it was automatic. It was made up of an air passage inside and a hollow water wheel. The air passage inside the wheel performs as pipes that flows cool air from the evaporating water into the openings and direct it to the rooms. 

It was not compact and convenient as compared to today’s models, but indeed it was a big advancement in direction of air coolers.

At that time people didn’t actually realize how air cooler worked, all they know was water makes things cool. But in 17th and 18th centuries when people were inventing things. They give a thought to it.

The interpretation of fluid mechanics advanced a lot during this period resulting in breakthrough called Dalton’s law. The English scientist John Dalton noticed that the rate of evaporation shoots up by the temperature of the water, when the wind flow fast over the water.

After understanding the basic fundamentals of air coolers the inventors started to experiment with this idea.  For instance, William Whitely came up with an alien idea of placing a tray of ice and a fan below a horse carriage.And the fan attached to the axle.

So when the carriage moved the fans spun and circulate the air into the carriage through ice tray. Thus making it the first air-conditioned conveyance.

Invention of an electric fan was the main reason for the advancement of air coolers. In 1920s people play on with the idea of using a fan to circulate air via a wet sheet was liked by many in desert regions.

The introductory air coolers were comprised of an electric fan positioned inside a wooden frame with a wet piece of fabric affix to it, and they were homemade. These tiny units were movable and very productive and pave the way for all the air coolers to come in future.

Companies and inventors harvest on the idea and step by step started to upgrade the design. What begin as a piece of wet cloth covered over a frame was soon equipped with water pumps and a tank to perpetually cycle water around the system, making the cooling result last for longer.

These ancient air coolers were more productive than before. They were also known as desert or swamp coolers at that time. But there was still more things to be improved. So the absorbent material made of wood chips replaced the piece of fabric in the middle with two wires to shield it from sagging.

This was so accurate that still most coolers use aspen pads and some models use more modern honeycomb pattern pads. And the wooden frames were vanished to be replaced by well-made delicate plastic housing.

Air coolers were big business by the early 1950s.Production methods had advanced gradually and companies around the world were able to bang out new designs and models in an organized manner.

For better performance and durability companies are now using advanced pump system and reliable synthetic material. The pump’s job is to make sure that the fabric is wet enough without engrossing more water and sagging.

At a time when air-conditioners are making their presence felt in the market, many households across the country still loves air-coolers. People usually opt for this cooling appliance for its nominal cost, much economical when it comes to bills and its quite environment friendly also.

Types of Air-Coolers:

Desert Coolers:

Designed for an extended area, Desert coolers are the bigger ones with the ability to store up to 40 to 60 liters of water. For outdoor use these are the best ones.

As they have mammoth fans and strong pumps with enormous tank capacity they are much productive in dry weather conditions also. Because of their castor wheels it is quite easy to move them. This one can help in keeping big offices, halls, banquet halls cool.

Personal Coolers:

Personal coolers are much more compact and movable compared to desert coolers. If you want to position it near your bed or dining table or sofa then this can work wonders for you.

With the tank capacity of 25 to 40 litres and consists of blowers for finer air delivery, especially designed for smaller areas these are cost efficient and make low noise compared to desert coolers .

Tower Coolers:

Tower Coolers are quite handy when it comes to narrow spaces. Its needle like shapes and artistic versions are best to fit in small areas. They provide you the best air delivery without taking too much space.

It can be easily used for long operational hours with its water tank capacity of 20 to 40 liters. Not much maintenance is required for these tower air coolers. And because of its sleek design,it’s very simple to clean this one. As they have rims attached to it, you can shift it from one place to other quite easily.

Window Coolers:

Window coolers are to be reinforced at the window which allows exceptional cooling as it pulls the fresh air from outside and then passes it. This is quite handy when it comes to low humidity area.

You can make them movable through trolleys which you can get apart if you are not interested in positioning them in a window. If you compare them with an AC they are much more energy efficient. As they use just 1/10th of energy used by an AC. With the water tank capacity up to 50 liters its best suited for indoors, small offices etc.

Air coolers are one of the most effective cooling solutions for beating the heat in summers. They are in demand because they are quite economical and are environmental friendly.

Choosing the right air cooler though can be a little confusing. We tried to help you out with this.

Key features to consider when buying an Air Coolers :

After deciding the type of cooler you would want, you need to decide a model which best suits your needs. Here are some of these features.

Water tank capacity:

The method that air coolers uses is called an evaporative cooling method. By this method water is transformed into water vapor. By blowing the air through fan or blower it reduces the temperature of the air.

It’s crucial to have larger tanks for coolers. The more capacity you have the longer the air cooler will run. Keep in mind that for your daily use you have to have the right size. Usually bigger rooms demands an air cooler with huge tank.

You will find extensive range of water tanks sizes in both desert and personal air-coolers. The range of a personal air cooler tank is about 20 to 30 liters of capacity whereas desert air coolers capacity is 31 to 50 liters approximately.


Same like an air conditioner it’s always crucial to buy the cooler according to size of the room. As the airflow of an air cooler is also studied in terms of CFM( cubic feet per minute). The CFM indicates the ratio of air circulated in your room each minute.

You can measure the CFM needed for your room and then pick the size of the cooler you want. By just dividing the cubic feet of your space by two you can measure the required CFM.

Fans can produce airflow with minimum pressure but in large volumes. They are generally used in big air coolers. Whereas blowers can produce high pressure air flow at high volumes. For this reason they are used in smaller designs.

Multiple speed setting is also an important aspect to inspect before you buy this allows you to check the airflow thus controlling the temperature of the room. Usually all the coolers come with three speed regulators.

It’s better to look for the one with automatic movement, to make sure that the air is flowing in all directions. When you use desert coolers in large spaces this feature is very important.


The main reason behind people’s hesitation to buy an air-cooler is the fact that they take up space and very often doesn’t go well with the interior also. Now manufacturers are playing smart and churning out some needle like designs and much glossier than before. For example tower air coolers are trendy and strong enough to cover the big spaces.

Air coolers that work on inverters

Air-coolers as we all know are popular because of their cost efficiency. Some manufacturers have come up with an additional feature of air cooler that can run on inverters.

This is quite a breakthrough because it consumes up to 50 percent less power than standard air cooler. So if you are worried about continuous power cuts in your area, this might be the right one for you.

Hope after reading this you may be able to pick the right one for your family. Go for the best beat the heat and enjoy summer.

Air Cooler vs. Air Conditioner – What is the Difference?

Many people get confused about the differences of an air cooler vs. air conditioner. Although an air cooler and Air conditioner are both used to cool down the air, each has it’s own benefits and disadvantages.

If you live in a climate that has high humidity levels, you should consider using an air conditioner rather than an air cooler. Air conditioners remove the humidity in the air, which increases comfort levels and makes it easier to breath. Air coolers on the other hand, add more humidity to the air because they use water when cooling the area.

Air Cooler vs. Air Conditioner Air Quality

Air coolers, also known as swamp coolers, operate by introducing fresh air into the system and then after passing by water, blowing that fresh air into the room. Air conditioners use the air already available and after cooling it, circulate it back out of the system.

If having fresh air constantly reintroduced into the room is important, you should choose an air cooler. Where as, if fresh air is not as important, you should consider either system, exploring other characteristics before making a decision.

Air Cooler vs. Air Conditioner costAir Cooler vs. Air Conditioner Operational Costs

Using an air conditioner to cool down the environment around you can increase your electric bill up to 50% when compared to months that you do not have to use one. This is a significant increase in electric use and cost.

Air coolers are very cost effective when compared to air conditioners. They can perform the same cooling process for approximately 75% less than that of an air conditioner.

If the cost of cooling your environment is a major concern, the air cooler is an obvious choice that will save you large amounts of money.

The Impact of an Air Cooler vs. Air Conditioner on the Environment

Some people choose to buy and use environmentally friendly appliances in order to conserve energy and preserve air quality for future generations. If these things are important to you, you should consider using an air cooler vs. air conditioner.

Air Cooler vs. Air ConditionerAir coolers use a natural method of cooling the air by a process of water evaporation. The system takes in fresh air and passes it by water soaked pads that cool the air, and then sends it back out of the system.

This process is very natural and preserves air quality. It also uses less electricity at the same time.

Air conditioners use a chemical refrigerant, such as Freon, to cool the air that is already present, and then the system sends that air back into the area. Some people believe that coolants can be harmful to the environment. They use a significant amount of electricity to perform the cooling task as well.

In the end, you will have to take all these things into consideration and decide which factors are the most important to you. Hopefully, this article has been helpful and informative regarding differentiating between an air cooler vs. air conditioner.
