Best Air Cooler in India Under 10000
A budget of ₹10,000 (±2000) is enough to purchase a decent air cooler for your home. While there are some expensive air coolers available for as much as twenty thousand rupees and above, they really don’t offer that much of value. And if you have a budget of rupees 20,000+, then why not purchase a 1.5 ton window AC for ₹20,000 to ₹25000 instead?
Further, if you check the customer reviews on these expensive air coolers, you will find that those who purchased these air coolers were not very happy with their purchase. We have therefore limited our search to air coolers under ₹10000 (±2000) .
How Do We Rate Air Coolers?
When compiling the list of best air coolers in 2021, we have used the following criteria in the order of importance:
- Air Delivery & Cooling Pad Efficiency: When it comes to air coolers, the most important factor of selection has to be its ability to cool the hot air effectively and the power with with it throws the air towards the room. For this reason, we have ranked high, the models with powerful air throw/air delivery and with large cooling pads.
- Safety/Durability Features: Because air coolers work for extended hours during summers, and also when we are asleep, its important that they are equipped with safety features. For this reason, we have given preference to models that come with thermal overload protection, low water level alarm, and voltage fluctuation protection.
- Customer Reviews: We consider problems reported by consumers very seriously. They tell you the real life experiences and it helps immensely to get the real picture about the quality, features, and durability of an appliance.
- Convenience Features: We consider the availability of convenience features that don’t effect the cooling performance but do help in making our life easier. We have given preference to air cooler models that come with remote control, auto fill, auto drain, and easy clean features.
- Service Quality: We consider the ability of manufacturer to provide good after sales service over a long period of time and in every part of the country.
Given these criteria, what are the Top 10 Best Air Coolers in India? Let’s take a look.

Best Air Coolers in India 2021– Buying Guide
Air cooler looks like a pretty basic home appliance but there are several things you should keep in mind when purchasing one for your home. Lets now look at the important things to know when selecting an air cooler for your room.
| Pro Tip: Never use an air cooler with doors and windows closed. On the contrary, place the cooler near a window or a door and also keep a few other windows open for cross ventilation. |
Air Throw / Air Delivery
This is the most important factor that will directly affect the cooling in your room. If you purchase an under powered air cooler then it will not cool your room effectively. Air won’t even reach the entire room and cooling would be low.
At the same time if you purchase an air cooler that is more powerful than required, then it will only create more noise and consume more electricity.
So, how to find out the ideal capacity of room cooler required for your room? The answer is check its air delivery rate and also calculate the air delivery rate required for cooling your room. Here is how we do it:-
Lets first calculate the air delivery or air displacement rate required for your room.
If your room is of size 18 ft (length), 15 ft (width), and 10 feet (height); then the air delivery required to cool your room would be:
Because most air coolers provide air delivery rate in cubic meter per hour (m3/hr), so lets convert CFM to cubic meter per hour. To do that, we will multiply the air delivery rate calculated above by 1.7.
1350 x 1.7 = 2295 m3/hr (approx.)
Therefore the minimum air delivery rate required to cool a room of 270 sq ft. (18 ft x 15 ft.) is 2295 m3/hr.
However, please note that the air delivery rate mentioned in air coolers if with fan in top speed. Therefore, its best to buy an air cooler with two times the minimum air delivery rate (in most cases). So that you can run it at top speed when needed and then operate at medium fan speed. Also, the air coolers with big fans usually come with large windows / cooling pad area, which directly affects the cooling capacity of air cooler.
Based on this, here are the recommendation for Ideal air delivery rate for rooms of various sizes:-
| Room Size in Sq. Ft. | Minimum Air Delivery | Ideal Air Delivery |
| 80 sq ft * | 680 m3/hr | 1500 m3/hr |
| 100 sq ft * | 850 m3/hr | 1700 m3/hr |
| 150 sq ft * | 1300 m3/hr | 2700 m3/hr |
| 200 sq ft * | 1700 m3/hr | 3000 m3/hr |
| 250 sq ft * | 2125 m3/hr | 3500 m3/hr |
| 300 sq ft * | 2550 m3/hr | 4200 m3/hr |
*In the calculation above, we have assumed the height of room as 10 feet.
Water Tank Capacity
The water tank capacity is another aspect that should be considered seriously. Personal coolers and some room coolers have very low water tank capacity and they usually need to be refilled in every 4 to 6 hours. This is a big inconvenience and can even result in water pump malfunction in case it keeps running dry in the night.
Therefore we recommend a minimum water tank capacity of 40 litre for room coolers.
Type of Cooling Pads
Cooling pads play an important part in cooling a room. They absorb water and allow air to flow through them to cool it.
Air coolers use two types of cooling pads – Aspen pads or Honeycomb pads. Aspen pads are made of wood shavings and honeycomb pads are made of cellulose material. Both type of cooling pads are good at cooling the air. However, the aspen pads would need to be changed much frequently than the honeycomb pads.
If you have a choice, then choose the air cooler with honeycomb cooling pads. They are comparatively more efficient, need little or no maintenance, keep water tank clean, and above all they have much longer life.
Humidity Control
Usually air coolers are recommended for cooling in areas that experience hot and dry weather. However, if you stay in humid areas, then you must make sure to buy an air cooler with humidity control feature.
Humidity control function in an air cooler works by controlling the functioning of water pump in a way that the humidity in the room never reaches uncomfortable level.
Inverter Compatible
If you stay in an area that experiences frequent power cuts in summers, then you must consider purchasing an inverter compatible air cooler. Such air coolers consume up to 50 per cent less power than a standard air cooler and can even work on inverters.
Safety Features
The most common reason of break down in an air cooler is dry running of water motor or overload or heating up of fan motor. To avoid this from happening, consider purchasing air coolers that come with protection against dry run and thermal overload.
Brand and Service Quality
When shopping online, you come across several brands that have no proven record of providing high quality product or services. You must avoid purchasing these cheap brands and stick to air coolers from trusted brands like Bajaj, Symphony, Crompton, Havells, Usha, and similar ones.

Air Delivery can be calculated in cubic feet/ min or cubic metres / hour. Most brands usually provide this metric in m3/hr.
How does humidity control work?
Humidity control works by automatically switching off and on the water pump according to humidity level in the room. When humidity in the room drops and temperature rises, the water pump gets started and when the humidity increases beyond a limit, the water pump gets switched off. This cycle keeps repeating, maintaining a comfortable level of humidity in the room. This is a must have feature in air coolers if you live near coastal areas.

That’s an excellent review covering technical aspects and price.
But I am surprised that a popular brand like Kenstar is not featured anywhere in the article. Is there any special reason? or it didn’t meet your criteria.
Anyhow.. I appreciate your efforts
We found kenstar air coolers to be costly compared to competition for no obvious reason.
I am impressed by the amount of good and clear content of suggestions and their details are given. Its really going to be provide a lot a value to the customer who want to know about the product more.
Appreciate your work thanks.
Thanks for the appreciation. Such feedbacks keep us motivated.
Can you please explain why the Cubic feet is divided by to and how the conversion factor 1.7 arrived at. Further are Voltas air coolers OK as a product.
Cubic feet is divided by 2 because we want air in the room to be exchanged twice per hour. Because 1 cfm = 1.69901082 cubic m/hr. So we use conversion factor 1.7 (rounded figure) for the convenience of readers.
Yes, voltas is a good company but we did not get a chance to review their air coolers. But I have personally used their room heater (Oil radiator type). I bought it in the year 2005 but when it developed a defect, the company did not service it. Their service center staff was surprized to know that Voltas ever manyfactured a room heater. Finally after following up with several people at Voltas, I had to get it fixed at local technician shop. It only needed a thermostat change.
Lesson learned – Never purchase a newly launched product line, even if its coming from a reputed brand.
Blue Star is also good which is not mentioned
Yes, Bluestar is a good company but its relatively new in air coolers (started selling coolers in year 2016). We have restricted our selection to well established air cooler companies. We may add some of their air coolers in this list next year. Thanks for the suggestion.
