Thus, if the air in your area tends to be dry, under the 60% level, you will actually fix two separate issues at the same time.

Cooling Speed and Efficiency

As warm air is drawn into it, the cooler filters it through the wet honeycomb media it features. This causes for the heat to be absorbed, naturally cooling and humidifying the air. As this process is over, the powerful fan tends to push the air out, efficiently cooling the surrounding area. No compressor is required for the process, which means that an environmentally-friendly and energy efficient option to keep cool is provided.

Operational Efficiency

As it presents a natural method to cool the air, the CL30XC is one of the most inexpensive to operate options to go for.

Using the simple yet efficient process of endothermic reaction, the SF-608R makes for a nifty solution to cool down when the temperature rises uncontrollably. It might be limited when it comes to the area coverage it provides, but seeing how this is a feature-rich cooler that comes at a cheap price, you cannot expect it to excel from all points of view.

Endothermic Reaction Explained

The SPT cooler is so effective at its job due to the technology it employs, more precisely the endothermic reaction. What happens is that the hot air indoors is passed through a water-saturated wick which absorbs it consuming all the heat and reducing the temperature of the air before dispersing it back into the room.

Antibacterial Water Tank

Your health is most definitely one of your top priorities, and the SPT puts an accent on keeping you safe from this perspective as it features an antibacterial water tank. The sterile environment in which the water sits ensures it will be free of germs, thus, what is released back into the room being clean air that is 100% free of harmful contaminants.

Boasting an uncomplicated operation, a high efficiency in terms of air cooling, and a low asking price, the SF-608R makes for a great companion during torrid summer days. There are few complaints we have regarding its quality, reason why we strongly recommend you take a bigger interest into this product as it is indeed worth your hard-earned money.


Although the performance provided by the evaporative cooler greatly depends on certain circumstantial aspects, like room size and relative humidity, by testing these household devices under normal operational conditions, we were able to figure out how to properly rank them. As the list of reasons why a water evaporation cooler is a must-have for people who live in hot and dry areas is absurdly long, we will only remind you of the two most important aspects which make it a desirable purchase – the low energy consumption and the fact that it helps raise indoor humidity. If your main interest when browsing for a cooler of your own is for it to cover as wide of an area as possible, the Honeywell CO60PM provides an 850 square foot area coverage that is sure to do the trick. On the other hand, if energy efficiency and low operational costs are your main interest points, then the SPT SF-608R is the one you will likely prefer as it draws only 60 watts to run. however, if you plan on using the cooler in the office, study, or bedroom, for example, and you are more interested in it to be quiet than anything else, the Hessaire MC37A will steal your heart with its 59 decibels output when set on the highest fan setting.
