CoolAir Review 2021 – Does It Really Works or Waste?

CoolAir Review

The summer heat is unbearable and to beat it you need a quality air conditioner. The problem lies in the solution. Air conditioners are notoriously expensive and can be extremely power hungry, increasing the overall price to match a small fortune. The simple solution is to invest in something effective, but not as expensive. Speaking about effectiveness, mini coolers are considered the underdogs of the bunch and never given much importance or respect.

What if we told you we have something that will change the mini cooler industry drastically? We bring to you CoolAir review, a compact air cooler that takes 10 minutes to chill down a room consuming way less energy than a basic air conditioner.

This compact, money saving appliance is truly one of a kind and whether it is portability or effectiveness or its energy saving capabilities, CoolAir blows its competition out of the water.

Not only that but CoolAir also strives to leave a pleasant smell around the room it is being used in. Its high portability means you can easily transfer the appliance between rooms and begin cooling there. Lets start our CoolAir review to give you every details which we tested.

What is CoolAir?

CoolAir is a compact, lightweight, power-efficient air cooler that can be placed in any corner of the room with the ability to cool down a room in under 10 minutes. CoolAir is unlike any other of its kind and when compared to other mini coolers, you realize how incredibly efficient and worthy CoolAir really is. It strives to be energy efficient, also proving to be cost-effective while putting all efforts in being helpful at cooling the room, i.e. its primary function.

Possibly the best alternate to traditional air conditioners, CoolAir is actually much easier to use than generic air coolers. Where with basic coolers you need to be vigilant about the water level, CoolAir simply shuts off once the water reaches a certain level, thus making sure neither extra energy is spent, nor inefficient cooling is performed. Filling its tub with water is also pretty simple and straightforward. It takes around 300ml of water to start working.

Designed to be portable, it is incredibly lightweight and so compact that it can literally fit in any corner of your room without causing a ruckus amongst the furniture. Besides its size and abilities, it is also much more efficient than other air coolers in every way imaginable. Not only it cools the air, but also works towards purifying the air and even humidifying it. Gone are the days where you pay top dollar to beat the heat. The new wave of air coolers are here! Starting with CoolAir.

How Does CoolAir Work?

How Does CoolAir Work?

Most of the evaporative coolers in the market are large appliances that look like portable AC units instead of mini coolers. These appliances are neither energy-efficient nor cost-effective. CoolAir on the other hand is a compact appliance ideally placed on top of a desk or the corner of a room.

The buttons on the top panel are easy to understand and make use of. You can easily adjust the speed and temperature from said buttons with ease. You also get the ability to change the colour of the reservoir to match your décor perhaps.

This evaporating cooler boasts a 750ml water tank. While reviewing CoolAir we found that its little difficult to remove at first, but once used to it, it is child’s play. The water in this tank is absorbed inside the cartridge, spreading over the surface of the cooling system. As the fan behind it blows hot air over the water, it evaporates, cooling the air and adding moisture to it. This process can last up to 3-5 hours and can provide cooling until then. After that, the water tank needs to be refilled.

Once the cartridge has absorbed ample water, the appliance starts operating at maximum capacity. The cooling depends on a variety of factors though, including ambient temperature, humidity, and even the temperature of the water in the tank (use ice for an actual cooling experience). Coolers are best used in hot, dry climates. We suggest keeping close to the appliance to feel its effects. If you are too far away, you might not feel its maximum benefits. The 3-speed fan setting helps to change the speed according to the temperature outside.

CoolAir not only cools but also filters and humidifies. The filter inside the cooler is efficient at trapping pollutants and allergens with relative ease and provides you with fresh clean air.

CoolAir is one of the easiest mini coolers to use in the market. No fancy gimmick, but a simple, intuitive design coupled with quality materials.


CoolAir simply provides too much. We asked for a good mini cooler and CoolAir delivered, and they delivered more. This appliance is also an incredible air purifier as well as a humidifier, perfect for the hot and dry climate. The 8 different mood lights also create a peaceful ambiance at night.


This appliance is notoriously energy efficient. While other coolers simply keep running, CoolAir shuts off automatically once the water is low enough, saving energy by the bunch.


The mini cooler is only 17cm x 17m x 17cm, making it hilariously portable and easily carried between rooms and even kept inside your car.


There is a tonne of mini coolers in the market. Some of them priced as high as basic air conditioners. But are they worth it at the price? After reviewing CoolAir, I do not think I would suggest anyone any other appliance but Cool Air. It is simply one of the best mini coolers we have had the good fortune to test for ourselves.
