Think air coolers don’t work in humidity? There’s some truth to that. Air coolers rely on water evaporation to bring down the temperature, and when the air is already loaded with moisture, evaporation slows considerably. That means you may not get the cooling you expect, and running the water pump continuously can make the room feel damp or sticky.
But that doesn’t automatically make every air cooler a bad buy during humid weather. Factors such as ventilation, cooler type, airflow and how you use the unit can make a difference. For homes with good cross-ventilation, an air cooler can still provide a useful breeze and some relief, particularly when humidity is not at its peak.
If you’re looking for one during the monsoon, we’ve rounded up air coolers currently available on sale, along with the features and specifications worth checking before you buy.
How to use an air cooler the right way during monsoon?
During the monsoon, an air cooler can sometimes make a room feel more humid instead of cooler. The key is to use it differently from how you would during hot, dry weather.
Keep the room well ventilated: Open a window or door slightly so humid air can escape. A cooler works best when there is proper cross-ventilation.
Use less water in humid weather: You don’t always need to keep the water pump running continuously. Try using the fan mode when humidity is already high.
Avoid using the cooler in a closed room: A closed room traps the moisture added by the cooler, making the air feel sticky and uncomfortable.
Turn off the water pump when it feels too humid: If the room starts feeling damp, switch off the cooling function and use the cooler only as a fan.
Clean the cooling pads regularly: Monsoon moisture can encourage mould, algae and unpleasant odours. Clean and dry the pads regularly.
Don’t place it directly against a wall: Leave some space around the cooler so air can circulate properly and moisture doesn’t accumulate around the unit.
Use it when humidity is relatively lower: If the weather is particularly humid or rainy, an air cooler may offer little cooling. On such days, a fan or dehumidifying AC can be more effective.
Simple rule: During monsoon, don’t treat an air cooler like an AC. Use the water pump only when evaporation can actually happen, and rely on ventilation to prevent excess moisture from building up.
Top 5 air coolers on Amazon Great Freedom Sale
The WELTHERM WX-SWIFT is a compact tower air cooler with a 6-litre water tank, honeycomb cooling pads and 500 CFM airflow. It offers three cooling modes, three fan speeds, oscillation and a 24-hour timer. A remote, touch controls, LED display and ice chamber add convenience for bedrooms, small rooms and offices.
Is this air cooler efficient in monsoon?
It can provide airflow, but evaporative cooling becomes less effective during humid monsoon weather, so use this without water.
The V-Guard Arido T50 H is a large 50-litre tower air cooler designed for powerful airflow and wider room coverage. It delivers up to 1,406 m³/h of air with a 9.14-metre throw distance.
Its 4D air circulation, dust and mosquito filter, castor wheels and low power consumption make it suitable for larger rooms.
Is this air cooler efficient in monsoon?
It can provide strong airflow, but high humidity reduces evaporative cooling, making it less effective during wet monsoon conditions. If used without water pump, it will be effective.
The Symphony Diet 12T is a compact tower air cooler designed for small rooms up to 12 sq. m. It features a 12-litre tank, honeycomb cooling pad, powerful blower and automatic louver movement for wider air distribution. Its slim design and energy-efficient operation make it suitable for bedrooms and other compact spaces.
Is this air cooler efficient in monsoon?
It can provide airflow during monsoon, but its evaporative cooling will be limited when humidity levels are high.
The BHABURLY GLX 35L is a portable air cooler with a 35-litre tank, honeycomb cooling pads and 2,000 CFM airflow. It features auto swing, three speed settings and an ice chamber for additional cooling. Its 105W motor and low power consumption make it suitable for rooms up to 235 sq. ft.
How to use this air cooler in monsoon?
Use it with windows open, limit water-pump use, and switch to fan mode when humidity is high to prevent excess moisture.
The Crompton Ozone Neo is a high-capacity desert air cooler designed for rooms up to 260 sq. ft. It features high-density honeycomb pads, 4-way air deflection and auto swing for wider airflow. Its 95-litre tank supports longer cooling, while the Everlast pump is designed to handle hard-water conditions.
How to use this air cooler in monsoon?
Use it with windows open, avoid excessive water, and run fan-only mode when humidity is already high.
Is a personal cooler better than a desert cooler in humid weather?
A personal cooler is generally not necessarily better than a desert cooler in humid weather. Both are evaporative coolers, so their cooling effectiveness drops as humidity rises because less water can evaporate. In a humid monsoon climate, a personal cooler may be more practical for a small, well-ventilated room because it moves less air and is easier to manage.
However, it will not solve the underlying humidity problem. If humidity is already high, using the cooler’s fan-only mode or an AC with dehumidification can be more effective.
Is it safe to use an air cooler when it is raining?
Yes, it is generally safe to use an air cooler while it is raining if the cooler is kept indoors and used correctly. The bigger concern is not the rain itself but water coming into contact with electrical components. Keep the cooler away from open windows where rain can splash onto it, check that the power cord and plug are dry, and avoid using the unit if there is any leakage or damaged wiring.
During heavy rain, humidity is usually high, so the cooler may also provide little cooling while adding more moisture to the room. In such conditions, using its fan-only mode and keeping some ventilation may be more comfortable.
