The Sharp Plasmacluster Ion Air Purifier with True HEPA Filtration and Humidification offers a unique combination of air treatment technologies and a one-touch automatic air quality control system to make you and your family more comfortable all year round. 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 will also indicate when filters should be cleaned. The KC-850U helps remove pollutants and common allergens such as pollen, dust, pet dander, and smoke with an ultra quiet fan that draws air through a three-stage filter system including a permanent micro-mesh pre-filter, washable activated carbon filter, and a long-life True HEPA filter, which captures 99.97% of particles as small as 0.3 microns from the air that passes through it. The KC-850U also reduces germs, bacteria, viruses, odors, mold, and fungus by using patented Plasmacluster Ion Technology, which disperses positively and negatively charged ions throughout the room to safely break down microorganisms and odors (even those trapped in fabric, carpeting, and drapery!). 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. In addition to auto mode, there are 3 manual fan speeds. The unit has LibraryQuiet™ operation (as quiet as 17 decibels, or the sound of rustling leaves) and is ENERGY STAR® rated, so you can run the unit continuously while saving money and energy.



Sharp’s exclusive patented Plasmacluster® ion technology eliminates microscopic pollutants that traditional filters cannot trap, by replicating nature’s own cleaning process of producing positive and negative ions from water vapor in the air. These ions refresh the air without any harmful chemicals or perfumes.


True HEPA filtration is ideal for removing common household allergens such as dust, pollen, pet dander, and smoke from the air. With True HEPA filtration, which removes 99.97% of airborne pollutants as small as 0.3 microns, including dust, pollen, pet dander, and smoke particles, more particles can be captured when compared to a HEPA-type filter.


Built-in temperature, dust, and humidity sensors monitor your air quality and automatically clean and humidify as needed, so you can sit back and enjoy healthier, fresher air!


Humidifiers can help relieve sinus issues, dry throat, dry eyes, and chapped lips. They can also help relieve dry skin caused by psoriasis, thyroid disorders, topical medications, and cosmetics. Heaters used in wintertime can also lower the humidity level in the air, so having a humidifier is helpful.
