Wondering how to select the best air cooler this year for yourself or your family
Finding the right cooler has never been easier with our cooler buying guide.
You should know at least about these things before choosing the right device
- Types of Cooler
- Types of Fan
- Types of Padding
Let’s start with types of air cooler suitable for your room.
Types of Air Cooler
There are three types of cooler
All these are designed to cater different needs
|Room Size||100-150 sq. ft||150-500 sq. ft|
|Water Capacity||10-40 ltr||40-100 ltr|
|Favourable For||Spot Cooling||Room, Outdoor|
Personal and tower cooler are similar, they just differ in design. Tower cooler is very thin and takes very low space.
On the other hand desert cooler is slightly bigger in size and features high air circualtion. It is best for dry regions.
Below you can find the pricing for each type of cooler.
Types of Fan used in Cooler
There are two types of fan used inside a cooler
- Normal Fan
Both differ in airflow mechanism, noise level, pressure used
|Used in Cooler||Desert||Personal/Tower|
|Air Circulation||Entire Area||Concentrated|

Types of Padding used in Cooler
There are two types of padding used inside a cooler
- Wood Wool
A cooling pad’s only job is to retain water and provide surface area for evaporation

Other Features to look in a cooler
Ice Chamber – This is a small space provided for placing ice cubes. Ice cubes can help in producing cooler air
Fan Speed settings – There must be speed settings provided in a cooler. Mostly we can see three speed settings inside a cooler – low, medium, high
Water level indicator – It should show how much water is left in the water tank
Empty tank indicator – It should indicate when the water tank gets empty
Castor Wheels – For better mobility it should have wheels
Warranty – It must have at least 1 year of warranty
Air Cooler Capacity Calculation
You can choose an air cooler based on the airflow or air displacement it can produce.
The CFM denotes the amount of air cycled into your room each minute.
CFM – Air displacement in Cubic Feet per minute
CFM = ( room area in square feet x ceiling height in feet ) / 0.84
Suppose, if you have 100 square feet room, ceiling height of 10 feet
CFM = ( 100 x 10 ) / 0.84
CFM = 1190.4
You will need a cooler with CFM value greater than 1190
CFM value is written on the product description like this.
Why should you buy cooler of a brand
When looking for a cooler
You have two options either buy a locally made cooler nearby or buy a branded cooler
Local coolers are cheaper
Let me tell you about an incident.
Once I bought a local cooler from my area and later found that it does not have fan speed settings.
Well, you would say that it’s my fault, I should have inspected the cooler before buying.
Speed settings are an obvious feature in a cooler so I did not inspect it.
If I had bought a cooler from a known brand that it is obvious it will have fan settings.
You will also get a warranty on the branded one whereas there is no warranty on the local one.
Frequently Asked Question
Which cooler is best for a closed room ?
You can use any cooler in a closed room, but do note it works best when cross ventilation is provided. By closing the door, you are reducing the ventilation. The humidity will eventually increase inside the room and the cooler will start to fail in terms of cooling
Why does desert cooler cool better on a hot dry day ?
Be it any cooler, it works on the process of evaporation for cooling. On a hot dry day, the humidity level is low making the evaporation process more efficient and thus cooling more efficiently
