Just when the winter months are gone, we all start looking for every possible cooling solution suitable for our homes. The first choice is almost always air conditioners, but they are sometimes difficult to avail because of the high price range and other maintenance criteria. But if you are looking for a budget-friendly portable cooling solution for your home, air coolers might be the thing for you.
The air cooler is basically a device that cools air through the evaporation of water. This evaporative system functions primarily on the basis of heat absorption and later on using that latent heat to transform water into vapor.
It is ideal for dry weather as it can significantly drop the temperature along with maintaining a comfortable humidity level through phase transitions of liquids. Most air coolers come with portable features these days, which makes them even more attractive. After researching hundreds of air coolers – comparing performance, design, and quality – we think that Bajaj Platini PX97 36 L Room Air Cooler is the best air cooler for home use in India.

There are several essential factors that you must consider before buying any kinds of air coolers. First of all, you should not focus only on the appearance of the product but also analyze the critical features and the warranty period. Secondly, you should also consider which brand to go for as it is imperative to have access to proper customer care and servicing facilities.
Air coolers are usually very easy to deal with, but they have some specific intrinsic features which you should be aware of so that you can choose the right product for yourself. Let’s take a look at the kinds of air coolers and their functions, general features, and other essential factors to consider for a fuller, wholesome knowledge.
To know how an Air Cooler works, watch this video.
Types of Air Cooling Technology
Direct Evaporative Cooling Technology
This is visible in the basic design of air coolers. In this technology, liquid water is transformed into water vapor with the help of the heat in the outside air. In that way, dry air is replaced with humid, moist air.
The moist air needs to be released to outside regularly; otherwise, the air becomes saturated with heat and evaporation stops. This technique is mostly used in all types of household air coolers.
Indirect Evaporative Cooling Technology
This technology uses direct evaporative cooling along with a heat exchanger to transfer the cool energy derived from the machine to air. The cooled moist air from the direct evaporative cooling process is never met with the conditioned supply air through direct contact.
The moist air stream is released in two ways. It can be emitted outside directly, or it can be used to cool other external devices such as solar cells. This kind of technology is used in bigger, industrial air coolers.
Types of Domestic Air Coolers
Desert Air Cooler
This kind of air cooler is suitable for medium or large-sized rooms or big office spaces. It can also be used outside. It uses evaporative technology to remove excess heat from the air by using them to transform the water into the tank into water bubbles. The capacity is usually more than 30 litres.
Personal/ Tower Air Cooler
This kind of cooler is ideal for small indoor setups only. It mostly uses blower technology to give direct cooling. The capacity of this kind of cooler is usually under 30 litres. They can also be of slightly bigger sizes and can have the appearance of a tower, which is aesthetically and spatially more compact.
Window Based Air Cooler
This sort of air cooler can be installed in the window, and thus it requires no floor space. The functionality is almost similar to the other ones.
8 Things to consider before buying Air Coolers
Air Cooler Capacity Calculation
This is the first fundamental thing to keep in mind before choosing an air cooler model, as the cooling coverage area is primarily determined by the capacity and air tossing ability of the unit. The satisfactory performance of the unit depends on how big a room it is being used for.
A 12-liter capacity based air cooler can cool up to 100 sqft area at most. Naturally, the bigger space is, the more capacity strength the air cooler unit needs or else the water tank would be empty even before you feel the chill.
Another thing to remember is that not every air cooler can function in an exterior space. For example, the Crompton Ozone 75-Litre Desert Air Cooler model is suitable for a big interior space as well as for outside area because of its huge capacity and effective cooling methods.
Floor Space and Room Properties
Air coolers are small in size and mostly have a tall tower-like structure, which makes it really compact and suitable for urban living spaces. They do not acquire much of floor space. But, you need to allot a well-calculated position to the unit from where the unit can equally distribute the cooling. The optimum level of temperature moderation is only possible if the machine is not blocked by any other furniture etc.
Another crucial factor is always maintaining a cross-ventilation for the room where the air cooler is functioning. Otherwise, the surrounding air would become saturated, and the cooler would not work effectively after a point.
Most air coolers, suitable for a medium-sized room, come at an affordable price range. You do not need to spend away from your future savings in order to be comfortably chilled during summertime if you opt for an air cooler. Practically, air coolers are way more cost-effective than air conditioning units, as they come at a 1/3rd price of any well-featured air conditioning unit.
If you do not want to buy more than one air cooler based on different space requirements and decide to go for a single larger model, it would naturally uplift the price to an extent. Models that come with features like dust-protection or purification other than basic cooling can cost a tad bit more than the regular ones.
You need to look out for the following things as well:
- Inverter Compatibility: As air coolers do not require much energy consumption, most of them are compatible with inverters. Try to look for a model that is thoroughly compatible with inverters or else you would be melting away during power-cuts.
- User-friendly Interface and Instruction Manual: The model must have a proper usage manual for secure handling. The interface should contain proper knobs and switches for simple operations.
- Water Level Indicator: If you are bothered about the task of checking the water level repeatedly, try to go for a model with a visible water level indicator. In that way, you would know in a moment if and when the unit requires refilling the tank, without any hustle.
- Warranty: Do not finalize a model before going through the warranty terms carefully. Proper customer service and post-purchase assistance are a few more important things to consider.
- Design of Louvers: In some models, you would find louvers that can be adjusted horizontally upwards or downwards according to your needs. But in others, they are fixed. Try to figure out which one you would prefer!
Advantages and Disadvantages of Air cooler
Just like every other electronic device, air coolers have their perks and drawbacks. Take a quick look at the following points for better knowledge.
- It is way more cost-effective than a centrally air-conditioned system. The estimated operating cost is about 1/8th of the refrigerated air conditioning unit.
- The main mechanical parts are the fan and the pump, which do not require a sudden surge of power, thus making it auto-immune to power-falterings.
- The primary working fluid is water, which is easily accessible and non-toxic.
- It is really very easy to operate and does not require any professional installation almost always.
- The Cooler continuously maintains a flow of fresh air into the room and thus alters the ‘age of the air’.
- It increases humidity that balances out the dryness in the arid areas.
- Even without an added purifying filter, the inbuilt cooling pad itself acts as a protective cover, preventing impure elements and dust.
- Air coolers can not alter the temperature of the surroundings as much as any refrigerated air conditioning units. The performance can not match up to the level of an AC unit in most cases.
- Humid conditions may decrease the cooling capacity as the main functional process of evaporation is hampered.
- High humid areas can cause water condensation, which can then lead to damage.
- It requires a substantial amount of water refilling. If there is a high level of minerals present in the water, the cooling pad can be obstructed. It can cause possible safety hazards.
- During wintertime, evaporative air coolers might need to be drained of water as otherwise, it can cause freeze-damage.
- There are a few hazardous conditions of health presented in air coolers. Firstly, the water storage tank can be a breeding nest of mosquitos, thus giving way to fatal diseases. If the unit is not maintained correctly, it can provide access to mold and bacteria into the interior spaces. Lastly, The usual wood-wool padding is highly inflammable and always needs careful attendance.
Which is the Best Air Cooler Brand in India?
There is not usually a definite answer to this ever-asked question. The best air cooler for home is the one that fulfills your specific needs. Considering all the factors mentioned in the buying guide and the detailed reviews, you can pick out the best one for yourself. If you are looking for a multi-usage air cooler at an effective price, Symphony Ice Cube 27 Litre Air Cooler (White-Blue) could be your chosen one. If you are willing to spend quite a few bucks for a more insured, bigger air cooler, then you must go for Crompton Ozone 75-Litre Desert Air Cooler (White/Grey). But if you are not willing to experiment much when it comes to an electronic device, you can easily choose the most preferred one that is Bajaj Platini PX97 Torque 36 Ltrs Room Air Cooler (White).
How is an air cooler better than air conditioners?
Air coolers are in every way different than air conditioning units. Where the regular air conditioners require wall-mounting or window installations, most room air coolers are small in size and are more energy-efficient, environment-friendly and low-budget. Though air coolers and portable air conditioning units are very similar in appearance, they function on two completely different mechanisms. Air conditioners function through a vapor-compressor or refrigeration technique, and air coolers work based on evaporation of water bubbles.
The working fluid in air coolers is plain water, and air coolers do not need any toxic refrigerants like ammonia or CFCs as used in AC units, thus making them non-hazardous for the environment. The basic mechanical parts of an air cooler are the fan motors and the water pump, both of which are easy to replace at a very low cost. The airflow in the air cooler is very frequent and voluminous, and it constantly enables fresh air to pass through the interior.
Another factor that makes air coolers more credible than air conditioners is the cooling pad technology, which can remove various contaminants from the air, including the urban Ozone caused by increasing pollution. Air conditioners might not be suitable in dry areas for this factor, as the refrigeration based mechanism can not keep the evaporative system wet enough and therefore become unable to wash away the impurities of the air through proper condensation.
Most air coolers come at a 1/3rd budget of a regular air conditioning unit, and they spare just around 1/10th energy as consumed by the AC units, thus making them more customer-friendly. Tower fans can be a good alternative to Air Conditioners too.

FAQ about Air Coolers
There is no definite scientific proof that air coolers cause asthma. It is usually quite friendly and does not tick off any kinds of diseases; rather, it prevents various allergy-related disorders. But, due to the increased level of humidity, it might cause distress to asthmatic people if not taken care of properly.
It depends on the model. You can put ice cubes in the water chamber directly if there is no separate chamber. In cases of different chamber facilities, the chance of enhanced cooling is elevated.
Again, it depends on the operating system of the cooler. It does not alter temperature as rapidly as an AC unit. Instead, it creates a chilling effect on the surroundings.
Most air coolers can function on 220-230 volts power sources. Usually, they spare about 100-140 watts, in cases of any personal or small desert air cooler. But the bigger ones might require around 200 watts power supply for uninterrupted operation.
There are several factors to remember before choosing the best air cooler for home in India. Keeping the size of the room in your mind, considering the amount of water you can spare and of course, the technicalities and features you should choose your air cooler. In our opinion, Bajaj Platini PX97 36 L Room Air Cooler is the best air cooler for Indian households.
