Top 10 Air Coolers in 2019 – Reviews and buyers guide
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.
How do air coolers function? Imagine being hit by the burning sun at noon to the point where you have to pour water on your skin. There is a cooling effect that comes to your body. Now the air coolers work on the same principle. The process of evaporative cooling.
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. 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.
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 maintanance cost and operational cost is making it ideal to fir low 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.
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.
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 Asthama 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 too 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
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
- Portability – 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.
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.

Frequently Asked Questions
1. Are Air Coolers Good For Health?
Yes. Air coolers do not have negative side effects on your health. If anything they make the air you breath fresher, cleaner, and more importantly moist. When the air is too humid, then the irritation that it causes on your nose is a question of discomfort and not health. We can comfortably say air coolers are safe for our homes.
2. Are Air Coolers Effective?
Yes. Only this depends on the level of humidity and the cross ventilation situation in your room. When humidity is high, then the effects of an air cooler are not felt. But when humidity is low air cooler comes to your safety by moistening the air you breathe in. A good balance with ventilation by opening the windows in your room will greatly boost the performance of an air cooler.
3. How Much Electricity Does An Air Cooler Use?
Air Coolers are one of the most energy conservative appliances at home. Even the premium large units hardly consume more than 200 watts of power. Acquisition and running costs of air coolers are considerably cheap.

Regular and thorough cleaning will surely help. Involve soap detergents and baking soda before heavily scrubbing the cooler parts. Rinse it more than once and finally spray a sanitizing agent.
5. Does Ice Help Evaporative Coolers?
In my own opinion adding ice would slow rather than hasten the cooling process in the room. This is because ice would lower the temperature, and for effective cooling to occur, water has to absorb heat from the air flow and then evaporate to the outside as moist air. Ice slows the evaporative process by lowering the temperatures inside.
6. Can We Use Air Cooler Without Water?
That’s a big No. All air coolers are naturally designed to use water. Essential especially for the evaporative cooling process. It is always advisable to check the water level in the water tank before starting to use the cooler.
7. Does Putting A Wet Towel Over A Fan Make It Cooler?
You can dip a towel in water and squeeze it to a point where it stops trickling water. When the wet dry towel cloth is used to cover the opening to the fan the air coming out feels colder.
8. Do Evaporative Coolers Cause Mold?
This group of the potentially hazardous fungus are common in damp places where water and air are stagnant. If such situations creeped into our homes the risk would majorly involve respiratory complications. One has to conduct routine checks and adopt a sound maintenance policy to keep away the molds from their air coolers.
Having discussed the different models and how they function, it is evident that air coolers are an integral part of our lives if we care about fresh air.
