• Continuous maintenance. To use the air cooler you need to fill the water in the air cooler water tank. It is continuous work, you need to fill before every night. Many people find it very much annoying. Apart from that if you live in water drought places the problem will be much worse.

Air cooler size calculation

Make sure the air cooler is sufficient for your room size. As we have mentioned earlier personal air cooler is good for small to mid size room and desert air cooler is best for large room size. Apart from that you can check the product description of the air cooler. Look for the 'Area covered' or ‘Cooling area’ specification in the model description. Area covered should be equal or more than your room size. For your reference we are attaching the screen shot of the Flipkart product description page.

There is another way to decide the same based on Air delivery or Air displacement (CFM). CFM denotes the total air in the room that's get changes in for every 2 minutes. But it usually mentioned based on hours making it more complex. While making purchase you can check the CFM as well. The formula for CFM is

CFM in hours = (room surface area in square feets * room height * 0.84)

For example, for 200 square feet home of height 8 feet, the required CFM is 200 * 8 * 0.84 = 1344.

Air coolers for high humid areas

By definition air coolers in high humid areas do not work well. If you still have air cooler in your home, try adding ice water to water tank, or put ice cubes in Ice cubes tray. Nowadays many brands saying they have “humidity control” feature. But based on our research we have not found any evidence saying how this “humid control” feature works and how effective it is. If you do know anything about it, please do send us the information. For example Symphony Hicool is such well known air cooler.

Air cooler features

There are so many terms on knowing air cooler add on features. Here is short summary on the commonly used terminology.

Ice cube tray

You can keep the ice cubes in the top tray of air cooler. Slowly when ice melts, the ice water gets added to the water tank.

Air cooler compatible with inverter

Many people mention this as saying that air cooler consumes very less powers so it even can run on the inverter. Air coolers consume very less electricity like 120 watts to 180 watts. Say you have lights and fan which consume 200 watts then buying 600 VA inverter is sufficient. Buying 900 VA inverter is more than enough.

Remote control feature

Just like AC, you can change or alter air cooler functionality using remote control.

Variable speed control knob

You can alter fan speed using this button, you can alter to low speed or high speed.

Water level indicator

As name suggest the water level indicator tells you whether water tank is filled or not. It is very helpful while filling the water. The indicator made of manually.

Tower air coolers

Make sure air cooler matches the aesthetics of your room. Tower air coolers are the latest buzz with new design trend in the market. Tower air coolers not only offer the new design but also save lot of floor space.

Multi-functional wheels

Empty tank alarm

When the water level is dropped below the required level, you can hear alarm indicating the lower water level. This feature is available in high end air coolers. This is very helpful, as running the air cooler without water may damage the air cooler motor. This feature is usually available in high end air coolers only.

Air cooler without water

This is the recent in buzz in air cooler industry. If a air cooler can run without water, then there is no need of extra water motor and large water tank, so making it very economical. Apart from that, if you are living in water scared place it can be great feature. This can be achieved by pushing air from large area to small exit, just like blowing from your mouth. Because of this change of pressure you can get cool air. But the effectiveness of cooling is very limited. There are very few models available online in India. They technology needs to be improved a lot to be well accepted as mainstream usage.

Air cooler usage guidelines

• In the beginning of summer, before you start using the cooler it is better to clean it off the cooler very well.
• The windows of the room or door should be open to make the air cooler functioning correctly. If you close all the doors and windows then humidity in the air increases and air cooler stop functioning.
• Cover the air cooler if you are not using it.
