Sharp's KC-850U Air Purifier / Humidifier adds humidity to the air for improved air quality and maximum comfort, especially in colder weather. It also helps reduce static electricity that results from dry air.

Bacteria, germs, mold spores, pollen, pet dander, smoke, dust and odors can make breathing harder, especially for asthma and allergy sufferers. The Sharp KC-850U air purifier / humidifier help remove these irritants with an ultra quiet fan that draws air through a three-stage filter system. Plus, their revolutionary Plasmacluster Ion Technology actively treats the air to make it healthier and cleaner smelling. For an even more comfortable environment, sensors constantly monitor the air quality in your room, adjusting the fan for air purity while providing the optimum humidity level. This combination of features is a smart way to choose cleaner, healthier, more breathable air.

The Science Behind Plasmacluster™ Technology

Exclusive to Sharp, Plasmacluster technology causes positively and negatively charged ions to be released into the air. These ions are unstable and are immediately surrounded by water molecules. The resulting clusters, which are called Plasmaclusters, spread throughout the room attaching to airborne particles and molecules. Plasmacluster air purifiers help in the elimination of pet odors, cigarette smoke and kitchen smells. This system effectively treats the air the way nature cleans the environment near waterfalls or just after a thunderstorm to help keep the air healthier and cleaner smelling.

Plasmacluster Ions Effectively Clean Every Corner in the Room

Plasmacluster® ions disperse throughout the room, actively attacking germs, bacteria, viruses, mold, and fungus, reaching more than conventional filter-based systems can! Traditional systems rely on air passing through the filter, but ions can spread to every corner of the room to actively clean. Plasmacluster ions destroy odors at the molecular level, even removing embedded odors in carpeting, drapery, and furniture.

  • Odor Reduction
    Plasmacluster ions can reduce odors - even those that are embedded in carpets, drapery, and furniture, such as cigarette smoke, cooking smells, pets, and perspiration.
  • Mold Reduction
    Mold spores are present in both indoor and outdoor air. Reducing the mold level in a home minimizes its affect on allergies and improves general health. Plasmacluster ions can dramatically reduce mold growth over time.
  • Reduce Static Electricity
    Plasmacluster® ions also reduce static electricity present in the room, so that small airborne particles such as dust, pollen, pet dander, and smoke do not cling to furniture and walls, and instead stay in the air, so that the airflow from the air purifier captures the pollutants in the filtration system.
  • Proven Safe & Effective
    Plasmacluster ions are proven to significantly reduce bacteria viruses, mold and fungus. It is so effective that it is now used by leading automotive companies to freshen the air inside cars, and in refrigerators to maintain freshness of food & kill mold.
  • Independent Laboratory Testing
    Sharp air purifiers are tested by independent laboratories to verify the air cleaning capability of the filtration system. Each model has its own CADR rating, which indicates the smoke, dust, and pollen removal rate when the air in the room is changed 5 times per hour.

The Science behind Plasmacluster Ion Technology

Plasmacluster Technology has been acclaimed by academic societies throughout the world for its advanced quality and has received many awards, including the Takagi Award from the Society of Non-Traditional Technology.

True HEPA Filtration in the Sharp KC850U Filters out Dust, Pollen & Smoke

  • Allergen Capture
    True HEPA filtration is ideal for removing common household allergens such as dust, pollen, pet dander, and smoke from the air.
  • Microns less than .03 Do Matter!
    Pet allergens and tobacco smoke particles are typically smaller than 1 micron(mic). 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.
  • True HEPA Filter with Ultra Long Filter Life
    Captures 99.97% of particles as small as 0.3 microns that pass through it, including pollen, mold, pet dander and dust. The special Antimicrobial Layer provides extra protection against viruses and allergens. Filters require changing only once every five years so operating costs are low.
  • Micro-mesh Pre-Filters
    Micro-mesh permanent pre-filters capture large airborne particles, including dust, pollen, hair, and pet dander, so it helps extend the life of the True HEPA & Carbon filters. It can be cleaned periodically by vacuuming or hand-washing.

The Sharp KC850U Includes a Built-in Humidifier

  • Relieve Dry Air Symptoms
    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.
  • The Ideal Humidity Level
    You may not know that keeping a steady humidity level between 40% - 60% in your home is ideal. When your humidity is too low, or too high, you may unintentionally encourage bacteria, virus, mold, and dust mite growth! Sharp air purifiers automatically deliver the right humidity level based on your room's temperature, so you never have to worry about setting it or turning it off!
  • Convenient Humidifying System
    The water tank for the built-in humidifier is easily removed from the side of the unit and can be filled at the sink with tap water. The rotating wick draws moisture from the water reservoir and releases it evenly into the airflow.
  • Antimicrobial Humidification
    When the humidifying function is not in use, the wick remains stationary and is suspended above the water level, allowing for the airflow to thoroughly dry the wick; thus preventing growth of mold and bacteria.
  • Water Supply Indicator Light
    When the water tank is low, an indicator light blinks on the control panel on top of the purifier.
  • Clean Humidification - No Residue
    Superfine mist leaves floors dry and surfaces residue-free.

The Sharp KC850U Air Purifier Automatically Detects, Displays and Responds

  • Built-In Sensors Monitor Your Air
    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!
  • Color Display Gives you a Reading of Your Air Quality
    It can be difficult to see what's in your air, since many airborne particles are not visible to the human eye. The color display on Sharp air purifiers help you "see" what's in the air -- by automatically sensing & reporting your air quality level, as well as the ambient humidity level!
  • Smart Controls Adjust Operation As Needed
    Based on air quality & humidity readings, the air purifier will automatically adjust operation as needed. When dust or other airborne pollutants are detected, the air purifier will change from low fan speed to high fan speed, to create a powerful air current throughout the room that will capture & kill pollutants. When low humidity (below 40% relative humidity) is detected, the air purifier will automatically add moisture to the air, to maintain an ideal range of humidity, between 40-60% relative humidity.
  • Library Quiet Operation
    Sharp Library Quiet™ air purifiers blend in with your everyday life and allow for a peaceful night's sleep.
  • Built with Energy Conservation in Mind
    Sharp True HEPA air purifiers are Energy Star rated, & highly efficient, so you don't have to worry about leaving the air purifier on all the time.
