A fan merely blows room air, but does nothing to actually cool the air around you. Air conditioners are designed to cool entire rooms, but aren't always effective in high sunload or insufficiently vented areas. The Kool Zone has a unique, patented, high efficiency water absorbing wick that is treated to prevent mold growth. During operation, sediments from tap water build up on the wick and gradually reduce its efficiency over time. We encourage you to add a replacement wick to your order when you check out.
