The Sharp Plasmacluster Ion Air Purifier with True HEPA Filtration and Humidification combines air purification and humidification to increase your family’s comfort. The automatic air quality control system uses sensors to constantly monitor the air quality in your room, adjusting for air purity and optimum humidity level, and also indicates when filters should be cleaned. This air purifier helps remove pollutants and common allergies such as pollen, dust, pet dander, and smoke. An ultra-quiet fan draws air through a three-stage filter system including a permanent micro-mesh pre-filter, washable activated carbon filter, and long-life True HEPA filter. The Plasmacluster Ion Technology disperses positively and negatively charged ions throughout the room to safely break down microorganisms and odors, even when they’re trapped in fabric, carpeting, and drapery.


The Sharp KC-850U Plasmacluster Ion Air Purifier reduces germs, bacteria, viruses, odors, mold, and fungus. Thus it is an ideal solution for allergy sufferers, asthmatics, pet owners, and smokers, and when used in humidify mode, can help relieve congestion, cough, and dry and swollen nasal passages. It is best used in a bedroom, living room, study, or exercise room. It has 3 manual fan speeds and LibraryQuiet operation (17 decibels, which is equivalent to the sound of rustling leaves). This quiet, Energy Star certified air purifier can be run continuously while saving money and energy.
