portable evaporative coolersAs the summer months progress and the heat begins to feel relentless, you may begin looking for some cool relief. Whether you are outside and blasting the A/C isn’t an option, or you are simply looking for a cost-effective and eco-friendly way to stay cool, portable evaporative coolers are the answer. And, although they are an affordable and sustainable alternative to air conditioning, when it comes to selecting the right portable evaporative cooler for your needs, size matters. Below, we will take a look at essential factors that you should consider when choosing the right size portable evaporative cooler for your space.

Understanding Portable Evaporative Coolers

Before choosing the perfect size portable evaporative cooler, it is important to understand how portable evaporative coolers work. Also known as swamp coolers, they draw warm air in and it passes over water-moistened pads, causing the water to evaporate and cooling the air in the process. The cooled air is then circulated back into the room, reducing the ambient temperature.

Assess Your Cooling Needs

Choose a portable evaporative cooler that’s the right size for your space and climate. Larger spaces or high humidity levels require more cooling power.

Calculate the Cooling Area

To determine the appropriate size of a portable evaporative cooler, calculate the cooling area by multiplying the length and width of the room you intend to cool. Then, match the cooling capacity to the size of the space you need to cool.

Consider the Climate

Evaporative coolers work best in hot, dry climates and may be less effective in humid climates. Some models offer adjustable fan speeds and dehumidification modes for cooling in humid conditions.

Air Exchange Rate

A portable evaporative cooler’s CFM (Cubic Feet per Minute) rating indicates how much air it can move in a minute. A higher CFM means more air circulation and faster cooling. Choose a cooler with a CFM rating that matches the size of your room for efficient cooling.

Choose the right portable evaporative cooler size for your cooling needs by assessing your space, climate, and other factors. Stay cool and comfortable all year long with an eco-friendly and energy-efficient portable evaporative cooler!
