Best Air Coolers in India Buying guide
How does an Air Cooler work?
Evaporation method is used by air cooler to cool the air. Regular supply of water is needed. There is pump by which water is dispersed from reservoir to the cooling pad in turns that gets wet. From the unit that is outside the fan draws air and guides it through the cooling pad.
From outside air the water takes up heat and evaporates. As the heat is transferred from air to water, the temperature in air decreases which makes it comparatively cool. The cool air is then heading inside the room. This process is constantly repeated and brings down all the temperature of the room which make the hot sunny days pleasurable.
It is most environment friendly of the space cooling, as the cooler working engage only with the water evaporation. Without the effect of global warming you can enjoy the coolers to cool yourself as there is not cooling gases is involved.
Types of air coolers:
Room cooler and desert coolers are the two types of cooler. With the difference of few features both work in the same way cooling the surrounding by evaporating the water. Both are used in different weather conditions.
|Room Air Coolers||Dessert Air Coolers|
|20-30 liters is the water tank capacity||30- 60 liters is the water tank capacity|
|Small to medium sized room can be cooled||Larger sized rooms can be cooled|
|These coolers are suitable for humid weather conditions||These coolers are suitable for dry areas|
|Blowers are mostly used in this coolers for cooling||Fans are used for cooling|
Room Air Coolers:
Areas with humid conditions is where these personal or room coolers are mostly preferred. Instead of normal fans these air coolers comes with the blower and is suitable for smaller rooms, price is lesser.
Personal cooler allows easy mobility as it is smaller in size it can be placed anywhere like kitchen, dining, bedroom etc and can be carried everywhere easily as it comes with caster wheels.
It has 20 to 30 liter water capacity; it uses low electric power than desert cooler which makes it more apt for household use.
Desert Air Coolers:
These air coolers are mostly suitable for dry area. They are designed for cooling large rooms and compared to personal coolers these are bigger. Cost is also little high compared to personal coolers.
Water capacity of these coolers is 30 to 70 liters; they are designed with fan to blow air more effectively. To draw the air from outside desert coolers should be mounted on your window. You will be able to move it from one room to other and is suitable for halls, restaurants, office, and hotel use.
Than a normal cooler desert cooler uses more energy, you can opt this cooler if you prefer excessive cooling.
If you need a cooling unit that is helpful to fight extreme heat then dessert coolers is the best option. If the room is smaller than room coolers would be enough.
Factors to consider while buying an Air Cooler:
The following are few factors to be considered before you buy air cooler.
1. Water Tank Capacity
The bigger the tank size the longer air cooler will run and the lesser times you need to refill the tank. According to your requirements choose a model that has enough water tank capacity.
The tank size is relative to the real size of the unit so the size should be enough big to store enough water and fulfill the space of the storage.
For commercial use select the tank capacity of 60 to 120 liters, for residential purpose select 30 to 50 liters tank capacity.
2. Cooling capacity Or Air Delivery
According to the size of the room you want to cool there should be the correct size of the cooler for it to work effectively. You need to have clear idea of the measurements of the room and the area should be more than the room size or else equal to it.
In the description or on the label of the cooler it will be clearly mentioned about the cooling area. You will find this under the heading “cooling area” or “area covered”.
CFM (cubic feet per minute) this the terms in which the air flow of the air cooler is measured. The CMF refer to the amount of air cycled in your room every minute. By calculating the CMF that is required for your room the correct size of the air cooler is calculated. The higher the CMF, the fan moves more air in the room.
To find the right size of the cooler you need there is the simple calculation which will help you out.(The denominator factor 2 is denoted as the air in the room gets changed once in every 2 minutes.)
Example: ceiling is 8 feet high and the room size is 100 sq feet in area then,
Air displacement or Air delivery (CFM) = 100 x 8/2 = 400 Cubic feet/ min
Many leading brands at present state the sir displacement in cubic meters/ hour.
Convert the CMF to cubic meters/ hour multiplies CMF value by factor of 1.699.In the example given size of the required cooler is 400CMF that is equivalent to
1.699 x 400 = 680 cubic meters/ hour (approx).
Having the correct size cooler is very important, it will take long time to cool if the cooler size is smaller and depending on difference in wattage it may consume more energy of the small and right sized cooler.
3. Cooling pads
Cooling pads gets moistened and it lets the hot air to pass through them to get them cool down, these cooling pads have direct influence on the efficiency of air coolers. Depending of the thickness of the cooling pad the outflow of the air is cooler. Cellulose and aspen are the materials they are generally made of they have their own pros and cons.
Honeycomb material require lesser maintenance and is more durable and efficient, these are made of cellulose material and take shape of honeycomb. Compared to our next variety these are slightly expensive.
The wool cooling pads seems like grass and is made up of shaving synthetic fibers from wood. The maintenance of the aspen wool cooling pads is high and are less durable and lesser efficient. It is more economical this is the only positive part compared to previous one.
4. Air Cooler Size
If you are lying on the bed and the cooler does not reach above your bed level is completely of no use, so buying a cooler that is adequate in height that throws air to your body level is important. You need to select the cooler that fits perfectly to your space.
Box shaped design and tall tower design are the sizes that air cooler comes. For box size coolers you can buy a separate stand with different heights.
5. Power Consumption
Before you buy the cooler check the power usage, the lower the watts mentioned the lesser the power it will consume. Anything between 160w to 220w is good. On the product description and sides of the cooler you can check the power usage.
6. Castor Wheels
It’s better to get an air cooler with castor wheels if you plan to use it in different rooms. A Castor wheel helps you to move the cooler around the house. Some come with attachable wheel option.
Castor wheels come with different types. Few come up with plastic which done last in long run as they lose the efficiency. Cooler with heavy duty castor is the best option. These are made up of thick rubber and strong metal material that suits best for long run and makes easy for you as you can push across the rooms more often.
7. Water Level Indicator
This indication helps you to know the water levels, this features helps the user to know if the water tank is full or when it runs out of water. In many cases this indicator is manual from which you will be understand easily to know how much water is required for entire tank.
8. Variable Speed Control Knob
Low, medium, and high are the three evaporative coolers come with. According to the intensity of breeze that you want, you can select the fan power, but the higher speed will be noisier.
9. Empty Tank Alarm
This feature is available in high end coolers, air coolers require basic level of water for it to operational, and this alarm helps you to be aware of it all the times. As you hear the alarm sound you need to fill up the tank as soon as possible, otherwise cooler will not work well.
10. Thickness of pads
The amount of water a pad absorbs which affect the cooling of air, based on the thickness of the pad; the air produced will be cooler. If you want to have a cooler that performs better you need to consider thickness level of 90mm.
Most of the people don’t prefer to buy air cooler as they take up lot of space and do not go with the aesthetics of the room. Manufacturers now a day’s come up with sleek and stylish design models, tower air coolers are trending in the market. These air coolers are powerfull to be used in large rooms and take up less space.
Tower models are suitable for hall or offices which blows air at certain height and two directions so it has to be placed to the corner of room. It is little expensive and not widely used in houses.
12. Remote Control Feature
Choose the air cooler that have remote, so that it will be easy for you to access the cooler easily. You don’t need to get up every time to change the speed settings; if you have remote system you can control the speed of fan easily.
13. Ice Cube Tray
Few coolers come with the facility of ice tray. You can keep the ice tray on the top shelf of the cooler, as the ice melts it mixes with the water tank and helps in cooling the temperature of water in few degrees.
14. Shutoff dampeners
Coolers are designed in the way that when they release cool air they ensure that coolness does not lash out of the cooler premise. Flaps or shut off dampers present at the discharge of fans preserve the cooling effect of air that comes from cooler.
Flaps are put along the duct, when the cooler is switched on they automatically open and closes when cooler is switched off.
15. Air Cooler Compatible with an Inverter
Air coolers are well known for low energy consumption. Some coolers have added features that can even work on inverters. Compared to standard air coolers these coolers consume up to 50% lesser power. If there is constant power cut at your home then this is the best option.
It is always good to choose a well known brand than local made and also check out the warranty. The well known brand always gives you good service, assist you better and they will come to house and fix it.
Air coolers that are listed here are all well recognized brands, you can make a purchase without any worry.
Checking a budget is also important before you buy the cooler. In India the best air coolers from the well recognized brands cost starts from Rs 5000 to Rs 12,000 and above. You need to pay little more if you want to buy a cooler with high tank capacity.
As of my choice, I would like to suggest anything around 30 to 50 liters of air coolers would be great, between Rs 6000- Rs 9000 you will get this type of air coolers.
Manufactures provide a year warranty generally as few other manufacturers may provide a longer period of warranty. Choose the model that have longer period, so you will be having protected and safeguarded after your purchase.
19. Effectiveness of Coolers in various temperatures
In the hot and dry climates air coolers works well. Depending on the evaporation of the water in atmosphere, the working of the air cooler depends. If the water evaporates more, you will get the cooler air.
For the air holding capacity of the atmosphere there will be a limit, if there is humidity already it will not be able to hold more water and give good result in getting cool air. It will be cooler in drier climates. Thus, Higher the humidity lesser will be the effect of cooler.
‘Humidity Control’ is the new addition to the coolers this overcomes the drawbacks. Many top brands like Bajaj, symphony models have this special feature and can be used in humid coastal region.
The figure shows relation between temperature that is outside and humidity in air.
If the air temperature is 90 Fahrenheit (32.3 Celsius) and humidity is 30% then outside air get cool up to 74 Fahrenheit (23.3 Celsius).
The temperature that comes from cooler also increases as the humidity go on increasing.
Advantages of Air Coolers:
- They are very eco friendly as they use water for cooling and also they are affordable.
- Easy to place them from one room to other, they are portable
- Low investment, initially buying a cooler is lesser.
- Compared to air conditioners, the power consumed by air coolers is less, as the annual energy saving is more.
- Cost of using coolers is lesser than using AC.
Disadvantages of Air Coolers
As there are advantages there are disadvantages also for air coolers.
- Main disadvantage of the air coolers is its dependency on climate. As there is high humidity coolers will be less efficient. Due to evaporated water the air coming from cooler is humid.
While you buy a cooler look for ‘Humidity Control’ feature.
- There should be continuous supply of water to use cooler. There are chances of corrosion if the water in your area is hard water, the internal parts of cooler will also get damaged. Maintenance is needed for this type of coolers.
- There is noise of the fan in coolers which may be disturbing.
Tips for better working of Air Coolers:
The tips of the better working air coolers are,
- The position of the air cooler should be in front of window. The evaporation will be faster, if the air is hotter. From the fan the cooler air is blown.
- The humidity needs to be pushed out to create the good ventilation in room. Due to this window of the room should be open. As it results in increasing the room temperature you should be careful that the window should not be opened too wide.
- Using ice water is good on very hot days as it will lower the temperature further.
- It is time to clean the cooler if there is foul smell, cleaning and maintaining will increase its lifetime.
- Keep cooling pads of cooler clean all time for good performance.
- Be sure there are no leakages and it is important to maintain the water tank clean.
- Cleaning of the fan blades will make sure that the air cooler will be of highest efficiency.
Air cooler Vs Air conditioner:
The comparison between air cooler and air conditioner are given in below table.
|Air Cooler||Air Conditioner|
|Air coolers prices start from Rs 3000 to Rs 15000.||Air conditioner cost between Rs 25,000 to Rs 50, 000.|
|Installation is not required for air coolers||Installation is little difficult for air conditioner, for window A.C there should be made proper arrangements and for split A.C proper drill should be done to walls.|
|These are eco friendly as it uses water for cooling the room||A.C uses harmful CFLs as refrigerant to cooling liquids, these are harmful for environments.|
|You need to fill water every time in the air coolers. 10 buckets of water is required for regular use.||On daily basis there is no maintenance required for air conditioner.|
|It uses outside air to cool the room down it circulates fresh air.||Internal air is circulated by using air conditioner.|
|Here fresh air is used||For Asthma patient make sure that A.C has bacteria filters.|

A: The following are the best brands of air coolers in India
Frequently Asked Questions?
The following are the best brands of air coolers in India
Yes. They can make the air cool using the evaporation mechanism. When water or ice is added in the air cooler, it evaporates them and spreads the cool air through the air flow dispenser.
The difference is the level of water absorption and also the evaporation process. The wood wool coolers are a bit pricey and also the power they consume is much more. As far as the water consumption is in question, wood wool coolers consume a lot more water than the basic honeycomb coolers. You have to make sure you prioritize your interest and select a one you wish to have.
You will not face any issues if you use a smaller capacity of cooler in a large area. The only issue you will face is uneven air across your room. Your room will not get a sufficient amount of air it needs and only a limited and particular area of the room will stay cool. To enjoy the best of the cooler experience it is highly recommended you take the capacity of coolers in the account.
Water capacity is not really an issue as far as the functionality is in question. You will be able to enjoy all the benefits the cooler has to offer. The only issue you will face is refilling the cooler. You will have to refill the cooler quite often if you purchase a smaller water capacity cooler, whereas if you choose a larger one, your labor will decrease to a great extent.
Almost all the coolers you will find in the market are already embedded with wheels which make it easy for the user to carry it across the areas easily. If you happen to come across a cooler you wish to purchase and have no wheels, you can always buy a stand with wheels on which the cooler can be placed. Such stands are easily available in the market so choose the stand which best goes with your cooler.
If the cooler has an additional chamber for ice tray, you can add on some ice in it and the air the cooler would produce is assured to be cooler as compared to the normal air. In case you come across a cooler which has no provision of ice trays, you can instead choose to add on ice in the water which would as well work and you will notice the chance of coolness in the air.
Humidity is what most of the coolers find a hard time battling. The climate really plays a very significant role in effecting the humidity of a particular are and that in turn affects the room temperature of your area. Hence, it is always best of your interest to have a cross ventilation provision available in the room. This would have an effect on the air produced by the cooler as the excess of humidity will be forced out the ventilator.
There is no such thing as no-noise coolers. Coolers do produce noise and that is a result of the technology with which they work. The fans, motor, the motion of water, etc all do have an impact on the noise produced by the cooler. But there is a slight differentiation in terms of the kind of fans which are used in the cooler and they affect the noise process. Such coolers are not noise-free but rather produce lesser noise as compared to regular coolers.
Yes, the quality of water which you use in the cooler does have an effect on the internal part of the cooler. There is a lot of hardware which is put together to get the cooler working. All such parts get in contact with the water and as a result, produce the air which comes out of the cooler. This is why the quality of water does matter.
If you live in a place having hard water, it would affect the functionality of the cooler. The way to cope up with this issue is to maintain the cooler. You need to take good care of the cooler and maintain it by cleaning it on regular intervals if you want to minimize the risk and the effect hard water has on the internal parts of the cooler.
Price does vary as a result of the additional features which are made available with the coolers. Examples of such features are empty tank warning, sleep mode, remote control, etc. These factors do matter but what needs to be taken into consideration is the element the coolers are made for. The capacity of cooling the air and by the efficiency with which the coolers work is the basic which needs to be sorted. Make sure you look out for the same and the additional features are extremely dependent upon your need.
It is forever advised to place coolers near windows. Place a cooler in a closed space is definitely a myth and works against the technology of coolers. If the air is hotter, then the evaporation process will be faster too and as a result, cool air is thrown out of the cooler. The humidity should be pushed out of the room and windows do that. But, it is also important that you do not leave the doors and windows wide open for the excess of humidity and temperature to enter into the room.
After evaporation, the air cooler allows the water vapor to revolve around the room. This is the reason humidity is increased, so they can be used in dry and hot weather conditions. If you use it in places that are already humid, then it can affect your health. There is a drain plug but the draining can be done manually only.
An increase in humidity is created when an air cooler is used. After evaporation, the air cooler allows the water vapor to revolve around the room. Water vapor in the air is called humidity, so they can be used in dry and hot weather conditions.
