How to Choose the Right Air Cooler for Your Home?


Sure, the rising temperatures are tempting you to buy an air conditioner, and why not? They are portable for moving from one room to another and can provide a cooling ambience in the space of the installation. But let’s get real: if you don’t know how to choose an air cooler, you will not be able to make the right decision. Don’t worry! We have curated this article especially for you to pick the right air cooler for your home.

1. Cooling pad thickness and quantity

An air cooler’s ability to cool is directly impacted by its cooling pads. They absorb water while allowing air to pass through to cool it. The thicker the cooling pad, the more effective the cooling. Cooling pads of an air cooler are typically made of aspen or cellulose. Aspen pads are composed of wood shavings as well as synthetic fibres. They are less expensive, require more maintenance, and have a shorter lifespan. Cellulose cooling pads, on the other hand, are thicker than aspen cooling pads, require less maintenance, and have a longer lifespan. They resemble honeycombs; hence, they are also known as honeycomb pads. These honeycomb pads are comparatively more expensive, but their efficiency makes every penny worth it.

2. Variable speeds and air mode

Air coolers automatically become more attractive options when they come with an option to regulate the speed. Variable speeds can help you control the speed of the fan inside as per your requirements. Some innovative coolers also offer three different air modes, such as normal mode, sleeping mode, and natural mode.

3. Power Consumption

These days, air coolers come in energy-efficient variants. Purchasing an energy-efficient air cooler will not only have a less negative impact on the environment but will also help you save money on your monthly electricity bills.

4. Water Tank Capacity

An air cooler makes use of the evaporative cooling method to provide a cooling ambience to your room. In this method, water is converted into vapour, which lowers the temperature of the air blown by the air cooler’s fan. It is essential to have larger water tanks, as they will enable the air cooler to run for longer hours. You must determine the number of hours you might need the air cooler to run before making a purchase.

5. Fan types

An air cooler can be fitted with either an axial fan or a centrifugal fan. The centrifugal fan is drum-shaped and usually quieter, but it uses more power for cooling and is costlier than the axial fan. The axial fan, on the other hand, is less expensive and consumes less energy, but it is a lot noisier than the centrifugal fan.

6. Garden hose connector

This connector allows you to attach a standard garden hose to the appliance for a continuous water supply while the unit is in use. This will save you time and energy by not requiring you to manually pour water into the water tank.

7. Remote Control

Find an air cooler that comes with a remote for easy access to settings. Air cooler remotes let you regulate the fan’s speed without having to physically move from your seat or bed to alter the settings.

8. Castors

Some air coolers simply use simple plastic castors that cannot be used for an extended period, particularly if the air coolers are to be moved quite often. Selecting coolers with heavy-duty castors made of thick rubber and sturdy metal materials is preferable.


Find Your Type and the Right Model


In your quest to find the answer to your question, “How to select an air cooler for home?”- you must learn more about the types of air coolers and then pick the one that best fits your requirements. The following table will help you understand the features of different types of air coolers for your better understanding:

Features Personal Coolers Tower Coolers Window Coolers Desert Coolers
Tank Capacity 10 to 30 Litres 25-50 litres 40-60 Litres Up to 90 Litres
Ideal for Office cabins, small rooms, etc. Medium-sized rooms. Medium-sized rooms. Larger spaces like backyards and halls.
Maintenance High Less Moderate Very Low
Portability Highly Portable Easy to move Not portable Heavy but portable

1. Personal Coolers

Personal coolers, also known as mini coolers, are the most commonly found air coolers for homes. These lightweight, portable coolers are designed for a personalised cooling experience in smaller spaces.

2. Tower Coolers

These coolers are among the finest cooling systems because they are specifically designed to provide superior air delivery. These are large appliances that, due to their stylish and slim designs, can fit into very small spaces.

3. Window Coolers

These air coolers are specifically designed for installation in windows and take up very little floor space. These air coolers are not portable, but they use less energy and provide more efficient cooling, which makes them a deal breaker.

4. Desert Coolers

Desert air coolers are ideal for regions with dry climates due to their large tank capacity, large blower or fan, and powerful motor. With their superior air throw and delivery, these coolers are quite capable of cooling down larger rooms. These coolers are heavy, but they are portable enough to move from one room to another.


Size & Capacity


While looking for the best suitable air cooler for your home, you must remember to measure the room’s size. Generally speaking, a personal cooler is recommended for small rooms, whereas tower coolers and desert coolers work well in medium- to large-sized rooms. The following table will help you identify the appropriate model based on your room size:

Room Size (sq. ft.) CFM Required Recommended Capacity (litres)
0-150 0-600 Less than 15 Litres
150-300 600-1200 11-30 Litres
300-450 1200-1800 31-50 Litres
450-600 1800-2400 41-60 Litres
600-750 2400-3000 More than 60 Litres


Features & Specifications


When trying to find the answer to your question, “How to buy an air cooler?” you must remember to first look for certain features and specifications. These are listed below:

1. Air throw distance

The fan and its blade profile are essential parts of an air cooler. It makes a big difference because a “nice-looking” cooler might not even perform well if it is unable to throw good air. The profile of fan blades achieves longer air throw, which means that coolers with high-angled fan blades are capable of delivering cool air to longer distances, leading to a greater area being cooled.

2. Room size

A small cooler in a larger space might not deliver sufficient cooling, whereas a large cooler in a small space may produce excessive humidity. There is a simple, standard formula for determining the proper size of an air cooler for your room based on the airflow required for the available room size. The airflow of a cooler is measured in cubic feet per minute (CFM), which refers to the air volume that the fan can blow per minute. The greater the CFM, the greater the area covered by the air cooler. You can use the formula:

CFM of Airflow = Room size (sq. ft.) * ceiling height / 2 

3. Quality of Cooling Pads

A good cooling pad can contribute significantly to keeping your space cold for an extended period. As previously stated, there are two types of cooling pads that can be installed in an air cooler: aspen pads and honeycomb pads.

4. Anti-mosquito feature

Today’s air coolers include an anti-mosquito breeding feature, which is highly useful for avoiding mosquito breeding within the cooler.

5. Ice Chamber

If you want your air cooler to deliver quick and amplified cooling, purchase a model that features an ice chamber. You can place ice cubes in the chamber to speedily cool the water, leading to quicker room cooling.

6. Inverter Compatibility

If you reside in a region with frequent power failures, you must choose an inverter-compatible air cooler to experience continuous cooling.

7. Dust Filter

A dust filter in an air cooler removes contaminants such as dust from the air that is drawn in from the outside.

8. Design

Air coolers are available in a wide range of shapes, sizes, and appealing designs, allowing you to select one that will blend in flawlessly with your home decor.

9. Convenience of Control

If you wish to access the settings as well as other functions of your air coolers without getting out of bed, a remote control will come in handy. You may additionally select smart coolers that are IoT-enabled, work on Wi-Fi, and may be controlled with voice through the use of voice assistants.

10. Tank capacity and auto-fill function

Since air coolers have various tank capacities, you must select the cooler with the appropriate tank capacity for your room size. The fundamental principle here is that a large water tank will provide cooling for extended periods, and vice versa. In addition, an air cooler with an auto-fill function will run all night without needing to be manually refilled.


Benefits Of Using Air Coolers


Here are a few of the many benefits of using air coolers in your space:

  1. Unlike ACs that circulate the same air into the room, air coolers circulate fresh air by drawing hot air from the outdoors and cooling it down. Furthermore, the circulated air is filtered, moist, and easy to breathe.
  2. Air coolers are pocket-friendly investments in comparison to their expensive alternatives, like ACs.
  3. Unlike air conditioners, which use harmful chlorofluorocarbons (CFC), air coolers use the natural process of evaporative cooling, which produces no carbon emissions, making them an environmentally friendly alternative.
  4. On average, an air cooler uses up to ten times less energy than a conventional air conditioning unit, promising a substantial reduction in your monthly electricity bills.
  5. Air coolers, unlike air conditioners, do not demand professional installation and operate as fixed units. Furthermore, air coolers are easily portable, which means they can be moved from one room to another with ease.
