What Tips can I follow to find the Right Size Cooler for home? 

The tips you can follow to find the right size of cooler for your home are:

  • Measure your room size: Check the length and width of your room, then multiply the two results to get the square footage.
  • Consider CFM: CFM in a cooler indicates how much the cooler can circulate per minute.
  • Select the Cooler Type: Desert coolers are a much better choice for large rooms and hotter climates.
  • Tank capacity: Check the tank capacity, as a cooler with a larger tank capacity means fewer frequent refills.
  • Consider other factors: Check out the room features such as high ceilings, sunlight, and your budget.
