Factors to consider when buying a air cooler for large room

• Air Delivery Rate (CFM): Choose a cooler with a high cubic feet per minute (CFM) rating to ensure effective airflow in larger spaces.
• Tank Capacity: A larger water tank means longer cooling hours without frequent refilling, ideal for big rooms.
• Cooling Pads: Honeycomb cooling pads are more efficient and durable than traditional ones, offering better cooling.
• Portability and Design: Ensure the cooler has castor wheels for easy movement and a compact design to fit your space.
• Power Consumption: Opt for energy-efficient models to keep electricity bills low while maintaining powerful performance.

What features should I look for in an air cooler for large rooms?

Look for high air delivery (CFM), a large water tank, multiple speed settings, and oscillation. Cooling pads, remote control, and portability also add convenience. These features ensure efficient cooling and better air distribution in spacious areas.

Are air coolers effective in humid climates?

Air coolers work best in dry climates as they use evaporation to cool air. In humid conditions, their efficiency drops because the air already holds moisture, making evaporation less effective. For humid regions, air conditioners may perform better.

How energy-efficient are air coolers compared to air conditioners?

Air coolers consume significantly less electricity than air conditioners, making them a budget-friendly choice for regular use. They use only water and electricity, without refrigerants, which also makes them more eco-friendly and easier on monthly energy bills.
