The Sharp KC-850U 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 of this medium-sized room
humidifying air purifier 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 medium room air purifier with humidifier 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.
