Chillmax Air Tower Plus is the free-standing, oscillating personal cooling tower that turns cold water, via a special hydro-chill technology filter, into cooler, humidified air. And, this new and improved model also features an adjustable grill for targeted cooling and a new 'honeycomb' design filter that transfers all that cool air where you need it more effectively. From the bedside to the office, Chillmax Air Tower Plus helps to keep your personal space nice and cool. With an oscillating feature to spread the cool air around, and three speed settings controlled by the easy-to-use control panel, and using no chemicals or toxic coolants, it filters the hot, dry air in your room to emit cooler, moist air. Simply fill with water, turn it on to one of the three speed settings, and enjoy!
