Top 12 Air Coolers – Reviews and buyers guide

People used to go for a split air conditioner or window air conditioners but since they are expensive most of us are now opting for air coolers instead. Air Coolers are becoming a standard to homes in areas that experience a mixture of hot air and low humidity. They are mainly used in dry places to curb scorching temperatures. Fast world cities too, where most of us reside, have the urban heat island effect that raises their temperatures. An urban home is by default hotter than a rural counterpart.

The two main components of an air cooler are the fan and wet pads. Both work in a collaborative move to lower the temperatures of the surrounding. While the fan sips in warm air and drives it to the wet pads to be moistened, the former acts as a surface where cold air evaporates into the atmosphere. The evaporative cooling process significantly decreases the air temperature by 20°.

What are the benefits of using an Air Cooler?

Production of Moisture

Water is one of the necessary ingredients for the functioning of an air cooler. Evaporative cooling releases a humidifying effect in the air. Hence many air coolers have humidity control. This is very important for the comfort of the occupants of a particular room. Air conditioners, on the other hand, suction in humid air causing the people around to have a difficulty breathing.

Cost Efficiency

Compared to the air conditioners, the air coolers are way cheaper both in the initial and operational costs. This is because the equipment itself is more affordable and evaporation takes up less energy. It cuts the power consumed by AC units by about 80%.

No Installation Required

The Air Coolers do not require any particular installation. You need to buy it, and you are ready to use it. Also, low maintenance cost and operational cost is making it ideal to low fir budget. Easy maintenance is an attractive feature for a home appliance. For the air coolers, the only action required is to refill the water tank. Which is more of a labor thing than it is cost.

Environmental Friendly

As mentioned earlier, water is almost the whole idea behind the working of an air cooler. The result is always low temperatures and high humidity. There are no harmful gas emissions to the atmosphere. Something that has been a big menace to the ozone layer. It also integrates a filter that eliminates contaminated air. Your home is safe with an evaporative cooling device.

To ensure maximum functioning of an air cooling machine, it is important to keep the windows open for cross ventilation. Air conditioners, on the other hand, work best in closed rooms. Which is considered less safe.

Health Benefits

There is a filter for dust and insects on air cooling models. This helps in preventing any sort of illness from the two factors. It also helps with  Asthma and water being the main ingredient means no emission of harmful gases. Like the ChloroFluoroCarbons(CFCs) which is the among the leading players depleting the ozone layer.

Even if you have not used it before you are still good to go. However, the devices have a limitation in places where humidity is high.

What are the shortcomings of using Air Coolers?

  • Since water is one of the functional needs of an air cooler, areas that experience shortage of the resource might not serve it right. If the water in your residence is limited, then the device might run dry for long hours. This comes as a barrier to the comfort that you would rather enjoy under minor electricity charges.
  • The noise that comes out of a working air cooler can be so disgusting and might interrupt other activities going in your home. The motor combined together with the fan can produce unnecessary noise that can make it hard for you to focus on your projects.
  • We cannot emphasize more on how important it is to check the humidity levels in your climate zone. Evaporative coolers humidify the air to cause the cooling effect. The success of this process entirely depends on the level of humidity out there. When it’s low, effective cooling occurs. The reverse is true.
  • Regular maintenance is required for the operations of an air cooler. You have to keep adding water to the tank on a daily basis. Which is so undesirable considering the multiple other chores we have at our homes.

Air Coolers or Air Conditioners?

Sometimes it might seem difficult to decide whether to buy an air cooler or an AC unit. But the difference between them is quite evident. An air conditioner, being more advanced, is obviously more expensive although that shows in its handy features. While it can provide both heat and cold in your room the air cooler can only be used to cool. This makes an air conditioner suitable for all weather.

Other distinguishing factors reflect on installation and maintenance part. The air cooler does not require any installation and can be used by any armature. Contrarily, the air conditioners require professional installation which to comes with cost implications. On the flip side, they don’t require any type of maintenance, unlike the air coolers where you have to keep adding water.

Of course, the air coolers are more convenient when it comes to portability and fresh air emitted. Air conditioners are immobile making them usable only indoors and emits poisonous gases.

What is the right size of an Air Cooler for your room?

Finding the right size of a cooler for your room is very important because of two main reasons. When you pick an undersized piece, it won’t sufficiently cool the entire room when the temperatures are high. On the other hand, if the unit is oversized them, it can cause discomfort with the massive cooling effect. The dimensions of the room play a key role in determining the size of a cooler.

You need to buy the air cooler according to the size of your room. It is calculated by considering the CFM (Unit used to measure the airflow)  i.e Cubic feet per minute.  Higher the CFM means more is the Airflow. Below a simple formula for calculating CFM is given

CFM = Area of the room * Height of the room/2


Instead of the rough hassle having to calculate your room area and matching it with the right air cooler. There is a shortcut to save those who hated Math back in the days. At the product description pages, they always display the area that a particular cooler can cover, together with its capacity. You only have to do a rough estimation of what area you have and see what fits. This is available in most online stores.

What are the various types of Air Coolers?

Personal/Room Air Cooler

This type of air cooler is applicable to rooms ranging from small to medium size. It is comparatively cheap and uses blowers for air circulation. One special feature about the blowers is that circulates air on a particular area as opposed to the whole room.

The capacity of the water tank is somewhere between 20-30 liters. Mostly appropriate to situations where one is looking for their individual cooling needs in their rooms.

Desert Air Cooler

Unlike the personal counterpart, this type is more advanced and delivers better results. For instance, the desert air cooler employs huge fans that circulate the air for effective cooling. It is important to realize that this comes with a consequence of bigger electricity bills.

They are mostly used in medium-sized homes and those that are large. The fans circulate air on the entire room to bring the cooling effect in every corner, something that is not possible with a blower. The water tank capacity is relatively large, between 30-60 liters. When you consider the cost, this type is more expensive than the room air cooler.

Tower Air Cooler

One major advantage about Tower air coolers is that their models are so quiet. Additionally, they are super light and portable. How they function is by distributing cold air vertically. This type of coolers removes heat from hot air by passing it through water in the cooling pads. The result is cold, clean air.

The industrial applications of Tower coolers include processing of cooled water for manufacturing, electric power generation, and air conditioning.

Buyers Guide For Air Coolers

With the rapidly advancing technology and the number of brands skyrocketing in the field, people always get confused on what Air Cooler to buy. In most cases, one would prefer an air conditioner but portability, efficiency, cost-effectiveness and other aforementioned benefits of a cooler makes it outstanding in its version. For a deeper understanding, let us look at the different features that you should watch for when buying an air cooler.

Control Panel

This includes a remote control that’s used for switching in between the modes and the timer where usually you can preset the time when your air cooler goes to sleep. Very important if you don’t need your device running all night.

Right Size

This is one of the very important things to consider as for any air cooler to work efficiently, one needs to know the size of the room. You need to buy the air cooler according to the size of your room. It is calculated by considering the CFM (Unit used to measure the airflow)  i.e Cubic feet per minute.  Higher the CFM means more is the Airflow. Below a simple formula for calculating CFM is given
CFM = Area of the room * Height of the room/2


Air coolers are highly portable. Because of its small and compact size, you can take the air cooler in any room and target that. The added benefit is that you can use it with doors and windows open unlike ACs

Water Tank

As the name suggests, this is the water storage for the cooler. The two functions; water level indicator and water level controller work hand in hand for a smooth flow. You read the water level in the tank from the indicator while the controller automates the process in which water flows in. It is so convenient and flexible to operate.

Cooling Pads

This is the most important part of an air cooler. There are two types; Aspen and Honeycomb cooling pads. As much as the design of the device determines the working of the cooling pads, the level of humidity in the air is equally important. For maximum efficiency, the thickness of the pads should need to be 90mm or more.

Speed Function

This lets you adjust to control the speed of the cooler. Helpful for a temperature rise when it gets a little bit cold.

Hose Connector

This part connects directly to the cooler and provides a constant supply of water. So you don’t have to keep refilling it.

Ice Gel Packs

To help further enhance the cooling effect, some models include ice compartments. During the extremely hot days, you can add more ice to catalyze the cooling process. This, however, can only work where there is low humidity. No amount of ice would bring a cooling effect when the level of humidity is high.

In Built Castors

for the mobility of the air cooler from one corner to another. Anytime you want.

Fan or Blower

If you have a smaller space to cool go for a blower type air cooler as they dispense air in a particular direction. Hence, it will be effective in cooling the particular space you wish to cool. On the other hand, a fan type air cooler is a good option for larger air coolers as it will spread the cool air in every corner.

Inverter Compatibility

Going for an air cooler that is compatible with an inverter is a good option. This enables you to connect the cooler to your inverter so that it can work in the summers without electricity. Hence, you get continuous cooling even during power cuts and it also saves power consumption.

Remote Control

You can check if the cooler you buy comes with a remote control or not. Having a remote control is an added benefit as it allows you to easily operate the air cooler without having to get off the bed. It allows you to conveniently change the fan speed to increase or decrease cooling.

To help you distinguish between the different brands and advantages attached to each of them, we have compiled a list for you. Some of them are expensive while some are cheap, depending on your budget. We carefully analyzed various brands to come up with a top 10 list of best air coolers you need in 2019.
