Our Recommendation For You

If it is for single person or small room usage, then room or tower air coolers are the right choice. For medium sized rooms, tower air coolers can be helpful. However, for larger areas or if the locality has harsh summer temperatures, then desert air coolers are the right choice.

Factor 2. What capacity should you choose?

Every air cooler is capable of cooling a certain area which usually depends on the water tank capacity. While purchasing an air cooler you have to check out whether the capacity is suitable for your room or not. For instance, an air cooler with larger capacity will be adequate enough for cooling larger rooms and vice-versa. So, you have to choose the capacity based on the room size.

Our Recommendation For You

Before purchasing, make sure to consider the capacity for optimal performance. Generally, smaller capacity is suitable for smaller rooms and larger capacity is suitable for larger rooms. Larger capacity also means that you don’t have to refill the air cooler frequently.

Factor 3. Types of cooling pads

Cooling pads have a direct impact on the cooling efficiency of an air cooler. Once they get wet due to water dispersal, they absorb the heat from passing air and cool it. For better outflow of cool air, you should prefer a thicker cooling pad. Two types of cooling pads are used – honeycomb and wood wool.

Honeycomb vs Aspen

2 – 3 Years




Does not smell much

Water Retention



Rs. 400 – 1000/pc

Our Recommendation For You

Honeycomb cooling pads are durable, efficient, and need less maintenance. However, they are expensive. Wood wool cooling pads are less efficient and require high maintenance. But they are affordable. You have to choose based on your preferences.

Factor 4. Other Features which you should consider

Now let’s have a look at the different features that help you understand the durability and quality of an air cooler.

1. Ice chamber

Some of the air coolers come with an ice tray facility where you can place ice cubes. When you turn on the cooler, the ice cubes in the chamber will quickly cool the water and result in instant cooling of the room.

3. Dust filter

This feature is particularly helpful for people who have respiratory allergies. The dust filter will trap the dust and other pollutants and prevent them from entering into the room.

4. Low Noise

Most of the coolers generate noise while working. But some produce a lot while some generate very less noise. Noise levels are usually represented in terms of decibels. Anything above 50 decibels is considered noisy. Higher the decibels, louder will be noise. So, check out the specifications before making the purchase.

5. Portability

If you plan to use the air cooler in different rooms, then choose a model with castor wheels. They help you move the cooler easily from one place to another. Castor wheels come with different types. Few come up with plastic which lasts in the long run as they lose efficiency. Cooler with a heavy duty castor is the best option. These are made up of thick rubber and strong metal material that suits best for the long run and makes it easy for you as you can push across the rooms more often.

6. Inverter Compatible

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% less power. If there is a constant power cut at your home then this is the best option.

7. Anti-mosquito feature

This special feature is available in Orient air coolers. They use a special repellent solution that prevents mosquitoes from breeding in the water. So, you don’t have to clean the water tank regularly.
