Choosing the right Air Cooler for your needs!

Mar 15, 2023

As the mercury soars and the sweltering summer heat sets in, we all crave the refreshing coolness of air coolers to beat the heat. Air coolers have become increasingly popular in recent years due to their cost-effectiveness and eco-friendly features. They are also energy-efficient and can be portable. Air coolers help maintain optimal moisture levels in the air, which can prevent colds and allergies, creating a healthy and comfortable indoor environment.

However, choosing the perfect cooler for your home or workplace can be a daunting task, given the wide range of options available in the market, each with its unique benefits. In this blog, we aim to guide you through selecting the ideal air cooler for your needs, considering important factors such as cooling capacity, energy efficiency, portability, noise level, and pricing. Our goal is to help you make an informed decision and find the perfect air cooler to keep you comfortable during the scorching summer months. Let’s take a look at the functioning and features of all types of air coolers to understand them better.

The Functioning of Air Coolers

Air coolers use water and a pump to keep cooling pads damp, cooling the air as it passes through. This effective mechanism relies on the water capacity, pump, and cooling pads. This simple but efficient process is environmentally friendly, energy-efficient, and easy to maintain, making it a popular cooling solution for homes and businesses in hot, dry climates.

Key Factors to Consider

When purchasing an air cooler, several key factors need to be considered to ensure that you select the perfect one for your needs.

1)     Room size:

When it comes to air coolers, the size of the room is a critical factor that directly impacts the type of cooler you choose. For larger rooms, coolers with larger capacity and stronger airflow work best, while smaller coolers are ideal for compact spaces and rooms. For instance, Desert Coolers are particularly popular choices for larger living rooms or drawing rooms due to their superior cooling capabilities. With Bajaj’s range of coolers with Anti- Bacterial Hexacool Technology, you get an additional feature of cool air that is also clean and healthy for all types of spaces.

2)    Airflow:

To ensure that an air cooler provides optimum cooling, it is crucial to have the right airflow for the size of the room. Airflow is typically measured in CFM (cubic feet per minute) and indicates the amount of air circulated within the room per minute. Calculating the CFM can assist you in selecting the appropriate air cooler for your space. To calculate the CFM required, divide the cubic feet of the room by two. Therefore, understanding the airflow and CFM is crucial for selecting an air cooler that can provide efficient cooling to your room.

 3)    Water Capacity:

Since air coolers operate using water and airflow, the water capacity of the cooler is a crucial factor in determining its run time. Air coolers with larger water capacities will run for extended periods without requiring frequent refills, making them a suitable option for areas with limited water availability. Therefore, choosing a cooler with an appropriate water capacity is essential for uninterrupted and hassle-free cooling.

4)   Warranty:

As pump failures are a common cause of cooler breakdowns, a pump warranty is essential when choosing an air cooler. The pump is a critical component of air coolers, and its quality and compatibility with hard water should be checked while buying. Bajaj's DuraMarine™️️ Pump has moisture protection, a two-year warranty, and higher-grade insulation for longer life and efficient performance. Pump failure is a common issue, but the DuraMarine™️️ Pump ensures smooth summers without any hassle.

To choose the perfect air cooler, you need to consider several factors, such as energy efficiency, size, cooling capacity, and features that cater to your specific requirements. With numerous options available, selecting the right one can be a daunting task. However, once you have a clear understanding of your priorities, the process becomes easier. Let’s research each type of air cooler and their pros and cons that can help you make an informed decision and stay cool all season long.

Pros and Cons of the 4 types of Air Coolers

To stay cool and comfortable during summer, air coolers are a popular option. However, there are 4 types of air coolers, each with specific functions and catering to different needs. To ensure a hassle-free experience, it is crucial to consider the benefits of each type and select one that fits your requirements. The types include portable, evaporative, ducted, and personal coolers.



  1. Desert Air Coolers are perfect for hot and dry climates with their energy efficiency and large water capacities.
  2. They are ideal for bigger rooms and open spaces with their powerful air throw.


  1. Due to their size, desert coolers are not ideal for portability.
  2. While easy to maintain, desert coolers require frequent cleaning to prevent cooling pads from dirt and bacteria.

Though Bajaj offers a range of desert coolers of capacities from 43 to 95 litres with castor wheels for mobility, enabling you to choose the perfect cooler for your space. With the uninterrupted operation, these coolers provide efficient cooling for longer periods.



  1. Personal air coolers are perfect for cooling small spaces and are most effective when you are close to them. They are also portable due to their small size.
  2. Not only do they consume less energy than desert coolers, but they also take up less space and are lightweight.


  1. Since personal coolers are for small spaces, using these in larger or open spaces might lead to lower efficiency hence room size is a key factor when choosing a personal cooler.
  2. Personal coolers can increase room humidity, which might not be suitable for humid climate areas.

These coolers come in various water capacities and boast powerful air throws. Bajaj personal coolers, for instance, have a capacity range of 23 to 36 litres and offer swing options and air throws of up to 25-30 feet.



  1. A tower air cooler fits in smaller spaces and has a sleek design.
  2. These air coolers throw the air at a higher level and are optimum for placement where one needs spot cooling.


  1. Since their air throw is at a higher level, therefore the cool air might be unevenly distributed.
  2. Tower coolers, just like desert coolers, require regular maintenance to avoid any issues.

Typhoon blower technology is available in Bajaj’s range of tower coolers that allow better air circulation. Bajaj Tower Coolers have water capacity options ranging from as low as 12 to 50 litres with a powerful air throw of 30 feet.



  1. Window coolers are specially designed to fit into windows, making them the perfect space-saving solution for cooling small bedrooms or office spaces.
  2. By pulling in fresh air from the outside and circulating it indoors after cooling it with water, these coolers provide efficient and effective cooling. Their unique design also makes them an excellent choice for apartments where space is limited.


  1. Window coolers are noisier when the compressor switches on or off.
  2. Once installed, they block window space and also cannot be moved around.

One of the best options in this category is the Bajaj Window cooler. It offers a 54 litres water tank capacity and a powerful air throw of 80 feet, catering perfectly to the needs of smaller spaces and providing practical and efficient cooling.

We hope that this guide has provided you with the necessary information to help you make an informed decision about the ideal air cooler for your needs. By selecting the right air cooler, you can stay cool and comfortable throughout the summer months.
