Air cooler is one of the best cooling solutions for places that are hot and dry. They are popular because they are economical to use and are environmental friendly. Picking the right air cooler though can be a little confusing. There are plenty of options in the market and many more features to consider. In this article, we take a brief look at all the important features one should consider while buying the best air cooler for your home:
Overview the Types of Air Coolers
There are 3 main types of evaporative air cooler:
Portable Air cooler
The advantage to the portable air coolers is their portability- most of them have wheels that enable them to be positioned throughout your home or business so that you can strategically cool any area, as you require.
Window Air cooler
If your cooling problems are localized to a particular room or area, a window air cooler is a great energy-efficient alternative to window air conditioners. These window-mounted air coolers often come ready to install and include the necessary installation hardware. Meanwhile, window air cooler can be easily installed in vertical or horizontal windows.
Industrial Air Cooler
Whether you run a hot warehouse or need to keep the workshop cool, industrial air coolers are economical and energy-efficient solutions to keeping your workplace comfortable. Industrial swamp coolers use circulation and evaporation to keep spaces cool. The dry, moving air increases the rate of evaporation from the reservoir and distributes the cool vapor evenly throughout your space.
Which Areas are Most Effective for Evaporative Air Coolers?
Evaporative cooling is among the earliest forms of weather and climate control still in use today, It is a simple, cost-effective method. Remember that breezing feeling you have on your skin after coming out of a pool? That is the simple idea of air coolers. However, depending on the climate where you live, Thus, Here a map to get the answer:
More parts of the world have been highlighted as areas where evaporative air coolers operate excellently.The world map of world for a huge green band and These areas have hot and dry climates that favor evaporative cooler. They are middle east, Central Asia, southern Europe and the West Coast of USA, Southern Africa, and Latin America.
The areas marked yellow are slightly cooler and are more prone to humidity. These areas include the United Kingdom and Western Europe where this technology works sufficiently well, but not at optimum efficiency. According to science, as global warming intensifies, these regions will develop a hotter climate that favors evaporating cooling techniques, implying that air cooler fan will be cheaper and much more efficient.
How do Evaporative Cooling Compare with Traditional Air Conditioning?
The goal of both of evaporative air cooler and traditional ACs is to cool your space. However, Evaporative cooling system are less operating cost, energy efficient, and are much more environmentally friendly than traditional air conditioning systems. Here is a small table comparing the differences between two types.
How to Choose the Best Air Cooler size?
To get the best air cooler results , make sure it is the correct size for your space. If an evaporative air cooler is too small for your area will wast energy to work extra hard to keep the space cool. The CMH (cubic meters per hour) is the amount of fresh air cycled through your environment each hour. To find the CMH, follow this formula:
For example:
Room Length: 10 meters
Room Width: 5 meters
Room Height: 3 meters
Volume of the Room: Length x Width x Height = 10 x 5 x 3 = 150 m³
Air exchange times in an hour: 20 times
Total volume of Air to be replaced in one hour: 150 cubic meters x 20 times = 3000 cubic meters per hour
According to the equation, you would need a air cooler with a CMH of at least 3000.
P.S.: Generally 20-30 air exchange times will be enough for your room.
Here some suggestions for your reference:
How to Choose a Best Air Cooler ?
More and more people choose to use evaporative coolers which could offer an eco-friendly and cost-effective to conventional AC. However, there are some things you have to know before buying a best air cooler.
Cooling pads have a direct impact on the cooling of an air cooler. They absorb water and allow air to flow through them to cool it. Thicker the cooling pad, the better the cooling.Cooling pads are generally made of aspen or cellulose material. Both have their advantages and disadvantages.
Aspen pads are made of wood shavings and synthetic fibre. They are cheaper, need high maintenance and have a shorter life.
Cellulose cooling pads are also known as honeycomb pads, mostly because they look like a honeycomb. They are thicker in comparison to aspen pads and have low maintenance and a higher life. They cost a little more but are also known to be more efficient.
Additionally, you also have to check the cooling pad quantity for each cooler. Some Air cooler fan only have single cooling pad, while some other have 3 or 4 cooling pads. It will gets better cooling performance once has more pieces of cooling pads.
Power consumption
With many evaporative air coolers comes varying energy efficiency. It is best to ask your dealer on what brand of evaporative air cooler is the most energy efficient, thus will have less negative impact on the environment.
Variable speeds and air mode
Variable speed coolers are used to control the speed of the fan. It is better if the cooler has options for regulating speed.Also some air coolers offers 3 different air mode like natural mode,normal mode and sleeping mode.
Water tank capacity
Air cooler fan make use of an evaporative cooling method. In this method, water is converted into water vapour, which reduces the temperature of the air blown by the fan or blower. It’s important to have air coolers that have large water tanks. Larger the water tank, the longer the air cooler will run. You need to select an air cooler that has a water tank that is the right size for your everyday use. A larger room would also require an air cooler with a larger tank. Both residential and commercial portable air coolers come with a wide range of water tanks sizes. Residential air coolers have tanks of 20 to 30 liters capacities while commercial air coolers capacities range from 40 to 120 liters
You can also call it at automatic water level controller. Some units have a hose connector.
This connector allows employing a standard garden hose to be attached to the unit for continuous supply of water is delivered to the unit while in use. It saves you the time and energy of manually pouring water into the reservoir.
Fan types
Evaporative air coolers can either be equipped with a centrifugal fan or an axial fan. The centrifugal fan is drum-shaped and is generally quieter but consumes more energy for cooling and costs more than the axial fan. The axial fan, on the other hand, is cheaper, uses less energy but is much noisier.
Water level indicator
Check if the portable air cooler has a water level indicator or not.
It will be more convenient for you to check the water level and know when it’s needed to add water. Anyway, it the air cooler already has a garden hose connector, such water level indicator is not necessary any more.
Castors
Check the castors that the Air cooler fan used. Some air coolers just use some simple plastic castors which could not be used for a long time, especially when you have to move the air coolers frequently. It’s better to choose the coolers with heavy duty castors which use thick rubber and strong metal materials.
Remote control
For quick access to settings, look for an Air cooler fan that comes with a remote. Remotes for air coolers will let you control the speed of the fan so you don’t have to get up over and over again to change the settings.

But let’s get real: if you don’t know how to choose an air cooler, you will not be able to make the right decision. Don’t worry! We have curated this article especially for you to pick the right air cooler for your home.
An air cooler’s ability to cool is directly impacted by its cooling pads. They absorb water while allowing air to pass through to cool it. The thicker the cooling pad, the more effective the cooling. Cooling pads of an air cooler are typically made of aspen or cellulose. Aspen pads are composed of wood shavings as well as synthetic fibres. They are less expensive, require more maintenance, and have a shorter lifespan. Cellulose cooling pads, on the other hand, are thicker than aspen cooling pads, require less maintenance, and have a longer lifespan. They resemble honeycombs; hence, they are also known as honeycomb pads. These honeycomb pads are comparatively more expensive, but their efficiency makes every penny worth it.
Air coolers automatically become more attractive options when they come with an option to regulate the speed. Variable speeds can help you control the speed of the fan inside as per your requirements. Some innovative coolers also offer three different air modes, such as normal mode, sleeping mode, and natural mode.
These days, air coolers come in energy-efficient variants. Purchasing an energy-efficient air cooler will not only have a less negative impact on the environment but will also help you save money on your monthly electricity bills.
An air cooler makes use of the evaporative cooling method to provide a cooling ambience to your room. In this method, water is converted into vapour, which lowers the temperature of the air blown by the air cooler’s fan. It is essential to have larger water tanks, as they will enable the air cooler to run for longer hours. You must determine the number of hours you might need the air cooler to run before making a purchase.
An air cooler can be fitted with either an axial fan or a centrifugal fan. The centrifugal fan is drum-shaped and usually quieter, but it uses more power for cooling and is costlier than the axial fan. The axial fan, on the other hand, is less expensive and consumes less energy, but it is a lot noisier than the centrifugal fan.
This connector allows you to attach a standard garden hose to the appliance for a continuous water supply while the unit is in use. This will save you time and energy by not requiring you to manually pour water into the water tank.
Find an air cooler that comes with a remote for easy access to settings. Air cooler remotes let you regulate the fan’s speed without having to physically move from your seat or bed to alter the settings.
Some air coolers simply use simple plastic castors that cannot be used for an extended period, particularly if the air coolers are to be moved quite often. Selecting coolers with heavy-duty castors made of thick rubber and sturdy metal materials is preferable.
In your quest to find the answer to your question, “How to select an air cooler for home?”- you must learn more about the types of air coolers and then pick the one that best fits your requirements.

When trying to find the answer to your question, “How to buy an air cooler?” you must remember to first look for certain features and specifications. These are listed below:
The fan and its blade profile are essential parts of an air cooler. It makes a big difference because a “nice-looking” cooler might not even perform well if it is unable to throw good air. The profile of fan blades achieves longer air throw, which means that coolers with high-angled fan blades are capable of delivering cool air to longer distances, leading to a greater area being cooled.
A small cooler in a larger space might not deliver sufficient cooling, whereas a large cooler in a small space may produce excessive humidity. There is a simple, standard formula for determining the proper size of an air cooler for your room based on the airflow required for the available room size. The airflow of a cooler is measured in cubic feet per minute (CFM), which refers to the air volume that the fan can blow per minute. The greater the CFM, the greater the area covered by the air cooler. You can use the formula:
CFM of Airflow = Room size (sq. ft.) * ceiling height / 2
A good cooling pad can contribute significantly to keeping your space cold for an extended period. As previously stated, there are two types of cooling pads that can be installed in an air cooler: aspen pads and honeycomb pads.
Today’s air coolers include an anti-mosquito breeding feature, which is highly useful for avoiding mosquito breeding within the cooler.
If you want your air cooler to deliver quick and amplified cooling, purchase a model that features an ice chamber. You can place ice cubes in the chamber to speedily cool the water, leading to quicker room cooling.
If you reside in a region with frequent power failures, you must choose an inverter-compatible air cooler to experience continuous cooling.
A dust filter in an air cooler removes contaminants such as dust from the air that is drawn in from the outside.
Air coolers are available in a wide range of shapes, sizes, and appealing designs, allowing you to select one that will blend in flawlessly with your home decor.
If you wish to access the settings as well as other functions of your air coolers without getting out of bed, a remote control will come in handy. You may additionally select smart coolers that are IoT-enabled, work on Wi-Fi, and may be controlled with voice through the use of voice assistants.
Since air coolers have various tank capacities, you must select the cooler with the appropriate tank capacity for your room size. The fundamental principle here is that a large water tank will provide cooling for extended periods, and vice versa. In addition, an air cooler with an auto-fill function will run all night without needing to be manually refilled.
Here are a few of the many benefits of using air coolers in your space:
Unlike ACs that circulate the same air into the room, air coolers circulate fresh air by drawing hot air from the outdoors and cooling it down. Furthermore, the circulated air is filtered, moist, and easy to breathe.
Air coolers are pocket-friendly investments in comparison to their expensive alternatives, like ACs.
Unlike air conditioners, which use harmful chlorofluorocarbons (CFC), air coolers use the natural process of evaporative cooling, which produces no carbon emissions, making them an environmentally friendly alternative.
On average, an air cooler uses up to ten times less energy than a conventional air conditioning unit, promising a substantial reduction in your monthly electricity bills.
Air coolers, unlike air conditioners, do not demand professional installation and operate as fixed units. Furthermore, air coolers are easily portable, which means they can be moved from one room to another with ease.
