Buying Guide for Air Coolers in India

Published 25 April 2023

Air coolers have become an essential appliance in India, thanks to the country’s predominantly hot and arid climate, when temperatures can easily reach 40 degrees Celsius.

In this practical guide from the HNK team, you’ll learn what air coolers are, what to consider when buying an air cooler, and tips to using your cooler efficiently.

Understanding Air Coolers

Before we dive into the intricacies of buying an air cooler, let’s understand what it is.

An air cooler is an electrical appliance that cools air through the process of evaporation. It draws hot air into the unit, passes it over water-soaked cooling pads, which leads to evaporation, and then blows out the cooled air into the room.

Air coolers are eco-friendly and consume less power compared to air conditioners, making them a popular choice in India where power consumption is a concern for many households.

Types of Air Coolers

There are three primary types of air coolers:

Personal Coolers

Compact and perfect for small rooms, personal coolers use blower technology to deliver air and are designed for spot cooling. Their water tank capacity is generally around 20-30 litres.

Desert Coolers

Ideal for large rooms or outdoor areas, desert coolers use fan technology to distribute cool air. They are known for their superior cooling performance and can hold between 31 to 60 litres of water.

Tower Coolers

These sleek, tall coolers fit comfortably into tight spaces and are suitable for medium-sized rooms. Tower coolers offer a balance between personal and desert coolers, usually boasting a water tank capacity of 20-40 litres.

What to Consider When Buying an Air Cooler

To ensure that you make an informed purchase, consider the following factors:

Cooling Capacity

This is determined by the size of the cooler and its airflow, often measured in CFM (Cubic Feet per Minute). As a rule of thumb, for every 2 cubic feet of space, you’ll need at least 1 CFM of air. So, calculate the CFM required for your room before deciding on the cooler size.

Water Tank Capacity

The larger the water tank, the longer the cooler will operate without needing a refill. Depending on your needs and the size of the space you want to cool, choose a cooler with the right tank capacity.

Cooling Pads

Cooling pads have a direct impact on the cooling efficiency. They come in two types: honeycomb and wood wool. Honeycomb pads, though slightly pricier, are more durable and efficient than wood wool pads.

Power Consumption

While air coolers are generally energy-efficient, their power consumption varies based on their size and type. Typically, air coolers should consume between 160 to 220 watts.

Noise Level

Some air coolers can be quite noisy, which can be disturbing, especially during night time. So, look for a cooler with low noise levels.

Additional Features

Look for features such as remote control, empty tank alarm, humidity control, and castor wheels for easy mobility. These features can add convenience to your experience.

Price and Brand

The price of the cooler will depend on its size, features, brand, and type. You can expect to pay anywhere between INR 5,000 to INR 15,000. Make sure to compare prices and features of different models to find one that offers value for money.

Buying from a reputable brand can ensure quality and good customer service.

Popular Air Cooler Brands in India

Some of the well-known air cooler brands in India include Symphony, Bajaj, Crompton, and Orient Electric.

Tips for Using Your Air Cooler Efficiently

Proper maintenance can prolong the life of your air cooler and keep it running efficiently. Here are some tips:

Regular Cleaning

Clean your cooler at least once every two weeks to prevent the build-up of dust and mould. Use a mild detergent and a soft brush to clean the water tank and cooling pads.

Cooling Pad Replacement

The cooling pads should be replaced when they’re damaged or heavily soiled. If not replaced in time, they can negatively affect the cooling efficiency.

Water Tank Cleaning

To prevent the growth of algae and bacteria, the water tank should be cleaned regularly. Make sure to drain and dry the tank if the cooler will not be used for an extended period.


During winters or when not in use, clean the cooler, dry it thoroughly, and cover it before storing it away. This will protect it from dust and prolong its life.


Ideally, place your cooler in a spot where there’s a free flow of air. Placing it near a window can be beneficial.


For optimal cooling, keep a door or window slightly open to allow fresh air to enter. This helps maintain air circulation and prevents humidity build-up.

Ice Tray

Adding ice to the cooler’s ice tray (if it comes with one) can enhance the cooling effect.

Humidity Control

If your cooler has a humidity control feature, adjust it according to the room’s humidity levels to achieve the best cooling effect.
