Portable Evaporative Coolers Review

Why Buy a Portable Evaporative Cooler?

Evaporative air coolers, also known as swamp coolers, differ from air conditioners in that they use water to cool air. Most effective in dry climates, evaporative coolers make your indoor space pleasant by circulating cool, humid air. They cost significantly less to install and operate than central air systems, although they produce much less cooling power. Portable evaporative coolers come in a range of sizes to fit a variety of spaces. They re lightweight and require only water and electricity to function, which means you can put them to use in your home or office with ease. We ve rounded up a list of some of the top products on the market, which include cooling units from manufacturers like Honeywell, Luma Comfort and Sunpentown.

Portable Evaporative Coolers: What to Look For

Buying the best portable evaporative cooler at the right price requires a fair amount of research to ensure you get the unit most suitable for your needs. If you choose a cooler that s too small for the intended area, it could be ineffective at lowering the ambient temperature. Likewise, it s possible to buy a portable swamp cooler that s too big and powerful. To help you find the ideal unit, we came up with a list of the most important factors to consider when choosing a portable evaporative cooler:

Aesthetic Design
Placing a portable evaporative cooler into your living space or office doesn t mean that you have to sacrifice appearance for comfort. Most portable coolers on the market are manufactured with aesthetics in mind. This means you don t necessarily have to share your space with an unsightly device that will look curiously out of place. To match a greater variety of living spaces and workplaces, some portable swamp cooler manufacturers make models of different colors   the most common being black, silver and white.

Weight & Portability
Since portable swamp coolers are intended to cool single rooms at a time, you may need to purchase a unit that s light enough for you to move around from room to room. More sizeable units are available to cool larger areas, but these can be much heavier and harder to move than their lightweight cousins. The best designed of the heavyweight units have caster wheels that make repositioning easier. If you plan on transporting your portable air cooler between your home and office, be sure its measurements are small enough to fit safely into the trunk or backseat of your car.

Size & Effectiveness
When it comes to portable evaporative coolers, bigger isn t necessarily better. At the same time, choosing a unit that s not big enough can leave you underpowered and overheated. The ability for evaporative coolers to efficiently cool their environment is rated in CFMs, or cubic feet per minute. All portable swamp coolers have CFM ratings, which makes it easy for you to figure out if a unit will be powerful enough to cool a given area. To calculate your ideal CFM range, first determine how many cubic feet you need to cool. This is done by multiplying an area s square footage by the ceiling height. For example, a 250-square foot room with 8-foot ceilings has a cubic area of 2000 feet (250 x 8 = 2000). To arrive at your ideal CFM, simply divide the cubic area in half (2000 / 2 = 1000). This means you will require a portable evaporative cooler with a CFM rating of 1000.

Bonus Features
The best portable swamp coolers aren t just lightweight and easily moveable, but they also come with extra features that could make them a more suitable and convenient choice. Some models come with timers, remote controls and automatic thermostats that will turn the unit on or off depending on the temperature of the room. Others include oscillators for more even air distribution, alarms that notify you if the unit is running low on water, and adjustable speeds of operation for gradual or rapid cooling. Some portable evaporative coolers also double as ionizers that remove pollutant particles from the air.

Evaporative cooling technology is most efficient in hot, dry environments and is not effective at lowering temperatures in areas that experience high levels of humidity. Since they require no compressors to operate, power consumption is significantly lower than a central air conditioner. On average, evaporative coolers can make the ambient temperature anywhere from 20 to 30 degrees cooler than outside air. Bear these facts in mind before you buy to ensure you choose the cooling technology that will best suit your needs.
