The C2 Climate Control (2007) employs a patented, energy-efficient thermal technology to deliver both heating and cooling from a single, compact unit. Consuming just 1.5 amps of AC current, the C2 uses approximately 90% less energy than a typical space heater. At the optimal distance of 18" from the user, this portable unit can increase air temperature by 32 degrees and decrease it by seven. Control the fan speed with a slide of the finger on the touchpad and change the direction of the airflow simply by adjusting the roller ball on top of the unit. The C2 not only improves your comfort level, it filters the air around you by intercepting particles of dust, pollen and dander as small as five microns. And, because the C2 is not a space heater, it doesn’t contain any exposed heating coils, chemicals or harmful emissions. No filling with water or recharging is necessary, and the filter is removable for cleaning. The unit will shut itself off after four hours, as an added energy saver. UL listed and plugs into a standard 110v AC. The C2 Climate Control is a fully licensed product of Herman Miller®, Inc.
