What is an Air Cooler?
An air cooler, or evaporative cooler, is a device used to cool the air by evaporating water into vapour form and dissipating into the atmosphere.
Air coolers differ from air conditioners by using only natural methods of evaporation to bring down temperature.
Rather than employing refrigerants or compressors to do their work, these coolers rely on natural evaporation processes instead.
Energy-efficient and eco-friendly air conditioners are great solutions for dry climates. But how exactly do they operate?
How Does an Air Cooler Work?
Air coolers work by drawing warm air from their surroundings and passing it over water-soaked cooling pads for cooling.
As air moves through these pads, water evaporates to help cool it further and further dissipate heat from the environment.
Air is then distributed throughout the room as a refreshing breeze.
Imagine standing near a waterfall on a hot day: simple, natural, and effective.
Types of Air Coolers

Not all air coolers are created equal. Depending on your needs and personal preference, there are various kinds of air coolers to meet them.
Here’s a breakdown of some of the more frequently occurring ones:
1. Personal Air Coolers:
These compact, lightweight coolers are specifically designed to meet your personal cooling needs.
These fans are perfect for cooling small spaces like your desk, bedside table or car.
Personal air coolers are portable, easy-to-use solutions designed specifically to provide spot cooling.
2. Desert Air Coolers:
If you live in an area with extreme heat, a desert air cooler is your best bet. These coolers are designed to handle large spaces and high temperatures.
They come with large water tanks (usually 30-50 liters) and powerful fans to provide maximum cooling. However, they’re bulkier and less portable than other types.
3. Tower Air Coolers:
Tower coolers are elegant, modern solutions perfect for medium-sized rooms.
Modern homes often prefer tall, space-saving couches that take up minimal floor area. Modern sofa beds can make an excellent addition to modern interior design schemes.
Tower coolers feature advanced features like remote controls, timers, and air purification filters for added convenience.
4. Window Air Coolers:
These air conditioners can be found inside windows.
Air coolers can provide an efficient cooling solution without taking up floor space, while being an attractive semi-permanent addition.
Window air coolers are efficient at quickly cooling a room, though they’re less portable than other forms.
Key Factors to Consider When Buying an Air Cooler
Choosing an air cooler can be daunting, but these criteria will help narrow your options down.
Let’s break it down step by step:

1. Room Size and Cooling Capacity:
Size matters when it comes to room design.
An average personal cooler won’t provide adequate cooling in a large living room, while a desert cooler might be too much of an overkill in a small bedroom.
Check your cooler coverage area, typically measured in square feet. For instance:
- Small rooms (up to 150 sq. ft.): To keep them cool and fresh, personal or compact coolers may be best.
- Medium rooms (150-300 sq ft.): Tower or medium-sized coolers should be considered.
- Large rooms (300+ sq. ft.): Desert or window coolers may provide optimal cooling solutions.
2. Water Tank Capacity:
The water tank capacity determines how long the cooler can run without needing a refill.
Smaller coolers have tanks ranging from 10-20 liters, while larger ones can hold up to 50 liters.
If you don’t want to refill the tank frequently, go for a cooler with a larger capacity.
3. Air Throw and Fan Speed:
Air throw refers to how far the cooler can blow cool air. A longer air throw is better for larger rooms, as it ensures even cooling.
Additionally, look for coolers with adjustable fan speeds. This allows you to control the cooling intensity based on your needs.
4. Cooling Pads and Material:
Cooling pads are the heart of an air cooler. They absorb water and help in the evaporation process. There are two main types of cooling pads:
- Aspen Pads: Made from wood shavings, these are cheaper but less efficient and need frequent replacement.
- Honeycomb Pads: These are more durable, provide better cooling, and are easier to clean. They’re a bit more expensive but worth the investment.
5. Portability and Mobility:
If you plan to move the cooler from one room to another, portability is key. Look for coolers with wheels and a lightweight design. Some models even come with handles for easy carrying.
6. Energy Efficiency:
Air coolers are already more energy-efficient than air conditioners, but some models are better than others. Check the power consumption (measured in watts) to ensure you’re not running up your electricity bill.
7. Noise Levels:
Some air coolers can be noisy, which might be a dealbreaker if you’re using them in a bedroom or office. Look for models with low decibel levels (around 50-60 dB) for quiet operation.
8. Additional Features:

Modern air coolers come with a range of extra features that enhance convenience and performance. Here are a few to look out for:
- Ice Chamber: Adding ice to the water tank can boost cooling performance, especially on extremely hot days.
- Remote Control: Adjust settings without getting up perfect for lazy days.
- Timer Function: Set the cooler to turn off automatically after a certain time. It’s a great way to save energy.
- Air Purification: Some coolers come with built-in air filters to remove dust and allergens, making the air cleaner and healthier.
Air Cooler vs Air Conditioner: Which is Better?

Both air coolers and air conditioners have their pros and cons. Here’s a quick comparison to help you decide:
Feature | Air Cooler | Air Conditioner |
---|---|---|
Cooling Mechanism | Evaporative cooling | Refrigerant-based cooling |
Energy Efficiency | Highly energy-efficient | Consumes more power |
Climate Suitability | Best for dry climate | Works in all climates |
Cost | Affordable | Expensive |
Portability | Portable | Fixed installation |
Maintenance | Easy to maintain | Requires professional maintenance |
If you’re on a budget, live in a dry climate, and want an eco-friendly option, an air cooler is the way to go. However, if you need powerful cooling in a humid area and don’t mind the higher cost, an air conditioner might be better.
Top Tips for Maintaining Your Air Cooler
To keep your air cooler running smoothly and extend its lifespan, follow these maintenance tips:
- Clean the Cooling Pads Regularly: Dust and dirt can clog the pads, reducing their efficiency. Clean them every 2-3 weeks.
- Change the Water Daily: Stagnant water can lead to bacteria buildup. Always use fresh water and empty the tank when not in use.
- Drain and Dry the Tank: If you’re not using the cooler for an extended period, drain the water and let the tank dry to prevent mold.
- Check for Leaks or Unusual Noises: Regular inspections can help you catch and fix issues early.
Conclusion
Choosing the best air cooler doesn’t have to be complicated.
Consider your room size, cooling needs, and budget, and don’t forget to check for additional features that make life easier.
Whether you’re looking for a portable personal cooler or a powerful desert cooler, there’s an option out there for everyone.
With the right air cooler, you can beat the heat and enjoy a comfortable summer.
FAQs
Air coolers are less effective in humid areas because they rely on evaporation. However, adding ice to the water tank can help improve cooling.
