At the center of the CB-19SL is Cool Boss Honeycool™ evaporative media, engineered to improve cooling performance while helping reduce water usage compared to standard cooling pads. As hot air passes through the water-saturated media, evaporation naturally lowers the air temperature before the cooler pushes that fresher air into your space.

The CB-19SL is ideal for dry environments with humidity levels of 60% or less, where evaporative cooling can perform at its best. With no compressor and no Freon, this personal swamp cooler offers a cleaner, lower-maintenance alternative to traditional AC for garages, workshops, patios, and home work areas.
