As days keep getting hotter and hotter it becomes increasingly difficult to tolerate the heat. Air conditioners being too expensive, air coolers are the way ahead.

To find the best air cooler we shortlisted all the products on the market and then selected the ones that offered the most features and the one which had the highest customer ratings. 

​Best air cooler in India (Medium sized room)

Symphony Hicool i 31 Litre Air Cooler with Remote Control

The Symphony Hicool Air cooler looks more like a cutesy robot that's sent to protect you from the harsh heat than an air cooler. The Hicool with its large 31-litre capacity means you won't have to refill it multiple times and the bundled remote control gives you all the convenience. Its 31-litre capacity and 37 feet air throw distance means it's great for medium sized rooms of around 175 sq. feet.  

​Best air cooler in India (Small sized room)

The Symphony Diet 22i contrary to what the name suggests is still a powerful air cooler that's designed for smaller rooms. The Diet 22i with its 22 litre capacity and nearly 30 feet air throw distance makes it more suited for smaller rooms of around 150 sq. feet.

Most found the air cooler very easy to use, especially due to the remote and the wheels which make it easy to move from one room to another.

Some complaints from customers were that the machine lacked upward and downward air flow control, lack of humidity control and loud operating sound. But these are expected given the price and working technology of the air cooler.

​Air cooler vs air conditioner

This is the first question you will have when you want to purchase an air cooler. Will the air cooler be as good as an air conditioner? Do I need to mount it? Will I have to pay more for its maintenance?

The main differences between an air cooler and an air conditioner is the working, where the air cooler works by the evaporation principle evaporating the water using the hot surrounding air. An air conditioner works on the refrigeration principle where it takes in hot air and introduces it to refrigerants which absorb the heat to give your cold air. This makes the air conditioner better for all types of regions while air coolers work well in only hot and dry regions and will not work properly in humid areas.

Unlike air conditioners, air cooler needs fresh air to work hence you need to keep your windows open for the proper functioning of your air cooler. This is actually helpful as you get fresh air rather than recirculated air from your room.

Given the complexities in an air conditioner, it is much more expensive than an air cooler. While most air coolers are around Rs.8,000 in price, air conditioners can start at around Rs.20,000.  Also with so much technology, it needs to be mounted to a fixed position. An air cooler meanwhile is portable and can be moved around anywhere including outdoors where it works perfectly.

Another merit to the air cooler is it is basically a plug and play device and needs no stabilizers or installation and even works on inverters. Air conditioners meanwhile need installation and stabilizers to run.

Coming to running costs, the air cooler doesn't hurt your wallet as much as an air conditioner as it consumes much less electricity. But there is one inconvenience as you have to fill an air cooler with water regularly which may annoy certain people. Also air coolers are much noisier the air conditioners in their daily working.
