245 CFM Air Purifier with Humidifying Function, Plasmacluster Air Purification System, True HEPA Filter, Energy Star Qualified, Library Quiet Design, Front Display and Manual or Automatic Operation. Adds humidity to the air for more comfortable air quality, especially in colder weather. It also helps reduce static electricity that results from dry air. Shows Plasmacluster operation, dust monitor and humidity level. Captures 99.97 percent of particles as small as 0.3 microns from the air that passes through it, including pollen, mold, pet dander and dust. The special Antimicrobial Layer provides extra protection against viruses and allergens. Splits water molecules into positively and negatively charged ions which spread throughout the room. This system effectively refreshes the air similar to the way nature cleans the environment near waterfalls or just after a thunderstorm. Shows the level of impurities in the air passing through the filter so it's easy to see the progress as healthier, cleaner air is returned into the room. Lets the user choose among 3 fan speeds and the Quick Clean mode. Uses sensors to automatically adjust fan speed for the degree of cleaning and/or humidification required. Library Quiet operation is ideal for bedrooms and living rooms. Silent Mode is as quiet as 19 decibels, about the volume of rustling leaves. The KC-860U is among the quietest Air Purifiers with a true HEPA filter available anywhere. Energy efficient operation means it's easy on the wallet. With its advanced technologies, it is 35 percent more energy-efficient than standard models, making it ENERGY STAR qualified. So it can operate all the time, saving money while improving the quality of the air. Filters require changing only once every five years so operating costs are low. The unit looks great in any home or office. Model Number: KC-860U. Air Purification System: Plasmacluster and Fan. Plasmacluster Ion Mode: On / Off. Plasmacluster Indicator Light: Yes.
