How to select an air cooler?
In this article, we are going to discuss about How to select an air cooler? With increasing temperatures, staying cool and comfortable has become essential. While air conditioners are a popular choice, air coolers are a cost-effective and energy-efficient alternative. Choosing the right air cooler requires an understanding of several factors, including cooling capacity, size, and features.
How to select an air cooler?
This article will guide you through the important aspects to consider when selecting an air cooler for your home or office.
1. Types of Air Coolers
Air coolers come in different types, each designed for specific needs and spaces. The three main types include:
- Desert Coolers: Ideal for large spaces and regions with dry climates. These coolers use large water tanks and powerful fans to provide effective cooling.
- Personal Coolers: Suitable for small rooms and personal use, these coolers are compact, portable, and use less energy.
- Tower Coolers: Slim and stylish, tower coolers are designed for modern interiors. They are effective for small to medium-sized rooms.
- Window Coolers: Installed in windows like air conditioners, these are great for cooling a specific room efficiently.
Choosing the right type depends on your space requirements and climate conditions.
2. Cooling Capacity and Room Size
The effectiveness of an air cooler depends on the size of the room it needs to cool. The cooling capacity is determined by air delivery (CFM – cubic feet per minute) and the water tank capacity.
A general guideline:
- Up to 150 sq. ft. – Personal coolers (10-30 liters tank capacity)
- 150-300 sq. ft. – Tower coolers (20-50 liters tank capacity)
- 300-600 sq. ft. – Desert coolers (50-100 liters tank capacity)
- Above 600 sq. ft. – Multiple or industrial coolers
To calculate the ideal CFM, use the formula:
For example, a 200 sq. ft. room with a ceiling height of 10 feet requires at least 1000 CFM air delivery.

3. Climate Considerations
Climate plays a crucial role in the performance of an air cooler. If you live in a dry and hot region, desert coolers work best due to their high cooling efficiency. However, if you live in a humid area, personal or tower coolers with humidity control and anti-bacterial features are more suitable. Evaporative cooling works best in dry areas but is less effective in high-humidity zones.
4. Water Tank Capacity and Refilling Options
Water is essential for air coolers to function. The larger the tank, the longer the cooler will run without refilling. If you live in an area with frequent water shortages, go for a model with a larger tank or an auto-fill feature that connects to a direct water source. Some advanced models also have water level indicators to alert you when refilling is needed.
5. Cooling Pads: Honeycomb vs. Aspen
Cooling pads are responsible for absorbing water and facilitating evaporation. The two most common types are:
- Honeycomb Pads: Made of cellulose, they are durable, efficient, and require less maintenance.
- Aspen (Wood Wool) Pads: Made of synthetic fiber, they are more affordable but require frequent replacement.
For better cooling efficiency, opt for air coolers with thicker honeycomb pads, as they retain water longer and improve cooling performance.
6. Power Consumption and Energy Efficiency
While air coolers consume significantly less electricity than air conditioners, choosing an energy-efficient model helps save on electricity bills. Look for models with inverter compatibility to reduce power consumption. A cooler with an energy-efficient motor and adjustable fan speed can further enhance savings.
7. Fan Type and Air Throw Distance
The type of fan or blower in the air cooler impacts air circulation. Generally:
- Blowers: Used in personal and tower coolers, they provide strong and directed airflow.
- Fans: Found in desert coolers, they deliver high air throw, suitable for large areas.
Air throw distance should be considered to ensure effective cooling. A cooler with adjustable louvres and oscillation features ensures even air distribution in the room.

8. Portability and Mobility
If you plan to move your cooler around the house, choose a lightweight model with castor wheels. Some models come with lockable wheels for added stability. Personal and tower coolers are more portable than desert coolers due to their compact size.

9. Noise Levels
Some air coolers can be noisy, which may disturb sleep or work. If noise is a concern, look for models with silent operation or low-noise motors. Generally, blowers produce more noise than fan-based coolers.
10. Advanced Features to Look For
Modern air coolers come with several advanced features that enhance convenience and performance:
- Remote Control: Allows easy operation without getting up.
- Timer Function: Helps save electricity by turning off the cooler after a set duration.
- Ice Chamber: Some coolers have a dedicated ice compartment to improve cooling performance.
- Dust and Mosquito Filters: Prevent insects and dust particles from entering the water tank and airflow.
- Smart Coolers with IoT: Some advanced models can be controlled via a smartphone app.
11. Budget and Brand Selection
Setting a budget helps narrow down options. Air cooler prices vary based on size, features, and brand reputation. Reputed brands like Symphony, Bajaj, Crompton, Kenstar, and Havells offer reliable performance and better after-sales service. Always compare models and read customer reviews before making a decision.
12. Maintenance and Durability
Regular maintenance ensures longevity and efficient performance. Consider coolers with removable cooling pads for easy cleaning. Models with anti-bacterial and anti-scale features prevent water contamination and scale buildup. Opt for rust-free plastic bodies over metal ones for durability.
Conclusion
Selecting the right air cooler depends on multiple factors, including room size, climate conditions, water tank capacity, cooling pad quality, and additional features. By carefully assessing your needs and comparing different models, you can find the perfect air cooler that keeps you comfortable without consuming too much power or requiring frequent maintenance. Investing in a high-quality air cooler ensures better performance, durability, and cost savings in the long run. So, make an informed choice and enjoy cool, fresh air throughout the summer season! So, Now I hope you have understood about How to select an air cooler.
