Ductless heating and air conditioning systems provide optimal comfort along with the reduced energy consumption that comes with zoned temperature control. The new XE ductless system features nanoe™ X — a built-in air and surface purification technology that provides a comfortable environment for occupants by reducing pollutants and odors. nanoe™ X penetrates deep into the fibers of carpets and furniture to inhibit pollutants and odors. The multi-step purification system, nanoe™ X and filter, requires minimal maintenance (only the filter). Since the nanoe™ X device is made from rugged titanium, no maintenance is required. Featuring whisper-quiet heating and cooling and advanced built-in air and surface purification technology, the new XE series sets a new standard for a comfortable indoor environment.
