As the weather gets hotter in summer, finding good ways to stay cool becomes really important. Usually, we use air conditioners and fans to stay comfortable when it’s hot outside. But now, there’s something new called evaporative air coolers. These coolers are designed to cool us down well and they’re also better for the environment. But can they really take the place of our reliable air conditioners and fans that have been keeping us comfortable for a long time?

What is an Air Cooler?

Evaporative air coolers, sometimes called swamp coolers, work in a simple way: by using evaporation. They pull in warm air through wet cooling pads, and as the air goes through the wet pads, it becomes cooler. This cooled air is then sent into the room, making the place feel nice and comfortable. This cooling method is natural, doesn’t use a lot of energy, and is good for the environment.

The Evolution of Evaporative Cooler

Keeping cool during hot summers has always been a priority for humans. From ancient times to today’s technology, the journey to stay cool has brought us to the innovative world of evaporative air coolers, also known as swamp coolers.

The development of evaporative air coolers has been a journey from ancient ingenuity to modern innovation. It all began with the ancient Egyptians using wet cloths to cool their homes through evaporation. In the early 20th century, commercial evaporative coolers appeared, offering cooling relief in dry areas. As time went on, residential evaporative coolers gained popularity in hot regions, using water-evaporation to create comfortable indoor spaces. With the 21st century came technological improvements, making these coolers more efficient and eco-friendly. Today, evaporative air coolers are recognized for their sustainable cooling solutions, especially in water-scarce environments.

From ancient wisdom to modern convenience, the history of evaporative air coolers showcases human creativity and our pursuit of comfort. These coolers connect the past and present, offering effective and eco-friendly cooling in a constantly changing world.

Different Types of Evaporative Air Coolers

When we’re trying to stay cool on hot days, evaporative air coolers come to the rescue. These coolers have different types, each made for different situations and places. Now, let’s explore the different kinds of evaporative air coolers out there:

  1. Portable Evaporative Cooler

Portable coolers are all about flexibility. They’re equipped with wheels or handles, making it easy to move them around your home. Whether you’re in the living room, bedroom, or kitchen, you can enjoy cool comfort wherever you need it.

  1. Solar Swamp Cooler

Solar evaporative air coolers offer a win-win solution. By harnessing solar power, they provide energy-efficient cooling that’s gentle on your wallet and the environment. Enjoy cooler indoor spaces without the guilt of excessive energy consumption.

  1. Window Air Cooler

Window coolers bring the outdoors in. These coolers are installed in windows to draw in fresh, cool air from outside. They’re perfect for maintaining good indoor airflow while keeping your space comfortably cool.

  1. Wall-Mounted Eco Air Cooler

For those looking to save floor space, wall-mounted coolers are the answer. These coolers can be installed on the wall, providing effective cooling without taking up precious room on the ground.

  1. Commercial Water Air Cooler

Commercial coolers are designed for bigger spaces like offices, shops, and restaurants. With their higher cooling capacities and larger water reservoirs, they’re well-equipped to keep larger areas comfortably cool.

  1. Compressor Evaporative Air Cooler

VEAC™ stands for Vankool Evaporative Air Conditioner,which is the world’s 1st commercially used Eco-friendly air conditioning system with proprietary technology.Two cooling systems are included in VEAC ™. The first one is an evaporative cooling system which is using water evaporation to cool the air. The second system is an air conditioning system which is using compressor technology.VEAC™ employs an innovative system integrating an evaporative cooling process and combining it with a refrigeration cycle to achieve optimal cooling performance at approximately 25℃.

Can Evaporative Air Coolers Replace Air Conditioning and Fans?

In the quest for more efficient and cost-effective cooling solutions, evaporative air coolers have emerged as a popular choice. But can these coolers truly replace traditional air conditioning systems and fans? Let’s delve into the benefits and limitations of them to better understand their potential.

In conclusion, evaporative air coolers can be a fantastic alternative to air conditioning and fans in the right conditions. If you live in a dry climate and are looking for an energy-efficient and eco-friendly cooling option, they might just be the perfect fit. However, in humid regions or larger spaces, they might not be as effective. As with any cooling solution, it’s essential to consider your specific needs and local climate before making a decision.

How to choose the best air cooler?

Evaporative coolers, are a popular choice for beating the heat while being energy-efficient and environmentally friendly. But with a variety of options on the market, how do you choose the best air cooler for your needs? Let’s break it down step by step.

1. Understand How Air Coolers Work

Before diving into the buying process, it’s essential to understand how air coolers function. Unlike traditional air conditioners, air coolers use a natural process of water evaporation to cool the air. Warm air is drawn through water-saturated cooling pads, where it’s cooled and humidified before being circulated into your living space. This process cools the air and adds moisture, creating a comfortable environment, especially in dry climates.

2. Consider Your Cooling Needs

Consider the size of the area you want to cool. Air coolers are most effective in smaller to medium-sized spaces. If you need to cool a larger room or multiple rooms, you might require multiple coolers or consider other cooling options.

3. Check the Air Cooler’s Cooling Capacity

Look for the swamp cooler’s cooling capacity, often measured in CFM (Cubic Feet per Minute). This value tells you how much air the cooler can move and cool in a minute. Higher CFM values are suitable for larger areas.

4. Evaluate Water Tank Capacity

The water tank size determines how long the cooler can operate before needing a refill. Consider your usage patterns and how often you’re willing to refill the tank. Larger tanks require less frequent refilling.

5. Look at Portability and Mobility

If you plan to move the desert cooler between rooms or use it outdoors, consider its portability. Some models come with wheels for easy movement, while others are designed to be stationary.

6. Consider Noise Levels

Air coolers typically produce less noise compared to traditional air conditioners, but noise levels can still vary. If quiet operation is important to you, check the decibel (dB) rating of the cooler.

7. Review Additional Features

Modern air coolers often come with additional features like remote controls, timers, adjustable fan speeds, and air purification. Determine which features are essential for your comfort.

8. Energy Efficiency Matters

One of the significant advantages of air coolers is their energy efficiency. Check the energy consumption and look for models with an Energy Star rating, which signifies energy-efficient appliances.


Choosing the best air cooler involves assessing your cooling needs, understanding how they work, and considering factors like cooling capacity, water tank size, portability, noise levels, additional features, energy efficiency, and your budget. Reading reviews and comparing brands can also help you make an informed decision. With the right air cooler, you can stay cool and comfortable during the hottest months while saving on energy costs and reducing your environmental impact.
