Buying Guide for the Best Air Cooler

Air Cooler 2

Air coolers are very popular nowadays because they are both budget and environmentally friendly. There are many features in air coolers nowadays, which makes them suitable for the places that experience dry summers. When we consider buying one, it becomes challenging sometimes, due to many options which the market offers. So we are here to help you out by providing you with every single detail one should know before buying an air cooler.

Working of Air Coolers

Air coolers use the technology of evaporative cooling. They work on a simple cooling process, which is as effective as modern air-conditioning technologies. In air coolers, they pull fresh air from behind and drives it through wet cooling pads. Evaporation of water takes place in these cooling pads, which brings down the temperature of the air. That cool air is then blown out from the cooler.

Types of Air Coolers

There are two types of air coolers in the market; one is a desert air cooler and the other one personal air cooler. Both of these are used in different climatic conditions.

  • Desert air coolers: Desert air coolers are mostly preferred in dry climatic conditions. These types of coolers are mostly larger than personal air coolers and are suitable for cooling large rooms. This cooler uses large water tanks and huge fans for delivering cool air to every corner of the room. Desert air coolers can be used outside without any issues, like in the backyard or terrace.
  • Personal air coolers: Personal air coolers are mostly preferred in humid climatic conditions. These are suitable for small and specific areas in a room. These coolers are quieter than desert air coolers and consume less energy. Personal coolers have smaller water tanks as compared to desert coolers but can provide cooling for hours.

Water Tank Capacity

Air coolers use the evaporative cooling method in which water is converted into vapor. This vapor reduces the temperature of the air and then is blown out by the blower or fan. It’s always important to choose an air cooler which has larger water tanks. When the water tank is larger in size, it offers cooling for a longer period of time, which proves to be beneficial. Most of the time, a larger room always requires an air cooler with a larger water tank, so a large tank is a must. Whether it is a desert or personal air cooler, both types of coolers come in a variety of tank sizes. The tank size of personal air coolers ranges from 20 to 30 liters, while the tank size in desert coolers ranges from 31 to 50 liters.


It’s always important to buy an air cooler which fits the size of your room. The airflow of an air cooler is measured in terms of CFM, i.e., cubic feet per minute. The CFM helps in denoting the amount of air cycled into your room per minute. By calculating the CFM required for your room, you can choose the right cooler for yourself. The CFM can be calculated by dividing the cubic feet of your room by two. Suppose your room is 400 sq feet in size, and the height of the ceiling from the ground is 10 feet. Then the CFM of your room will be 2000 (400 sq ft X 10 ft/2).

The airflow of an air cooler varies if it uses a blower or a fan. Fans create airflow with low pressure, but in large volumes, these are mostly used in big air coolers. Blowers, on the other hand, creates high-pressure airflow with high volumes; that’s why they are used in small models. An air cooler that has multiple speed settings is always the right choice to make when you are considering buying one. This system of speed controlling enables us to control the temperature of the room. Most of the air coolers nowadays come in at least a three-speed regulator. You can also opt for air coolers, which feature a swing system; this enables cool air to flow in all directions.

Cooling Pads

Cooling pads have a very important role to play in an air cooler. Cooling pads absorb the water, and when air passes through them, it helps in cooling them. The thicker the cooling pad is, the better will be its cooling. Cooling pads are generally made up of two materials, aspen, and cellulose. Wood shavings and synthetic fibers are used to make aspen pads. Aspen pads are cheaper but need high maintenance, and they have a shorter life. Now when talking about cellulose cooling pads, they have a unique design that looks like a honeycomb. These pads are thicker in comparison to aspen pads and need low maintenance. These pads cost a little extra but are worth the money, as these are more efficient and have a longer life.

In-Built Inverter

Air coolers already take low energy to operate. Nowadays, manufacturers have introduced air coolers, which works even on inverters. This feature enables standard air coolers to work even on 50 percent less power than before. You can notice the difference in the electricity bill. These coolers are ideal for those households which face constant power cuts.

Remote Function

Now the last but not the least feature which one should look for in today’s coolers are remote control functionality. This feature enables us to control the cooler fully without bearing the hassle of operating it manually.

Frequently Asked Questions 

Air Cooler 3

1) What are the primary differences between an air cooler and a conditioner?

The air conditioner actually uses some sort of chemical cooling refrigerant in order to absorb the condensed hot air while cooling it in the process. In the case of an air conditioner, the hot air must be expelled outside the house. Generally, the price of air conditioners increases drastically, the more efficient it becomes while consuming less electricity.

Air coolers, on the other hand, uses the natural water evaporation process in order to expel the cool air coming out of it. With the presence of liquid water in the air, it raises the humidity while providing a cooling sensation. The cost of maintaining and keeping an air cooler is significantly lesser as compared to that of an air conditioner.

2) What are the benefits of using Symphony air coolers?

One of the biggest advantages of having the Symphony air cooler is that it always uses some of the most budget-friendly cooling options. This, in turn, can bring down the overall cost of the cooler while making it affordable for the purchase. Further including, symphony air coolers use very little electricity while operating.
