This item includes the following crucial functions that are behind the term 4-in-1 used to describe it:

  • Ionizer: What you have here is Sharp’s exclusive patented Plasmacluster Ion Technology. So positive and negative ions are dispersed into the air. They attach to the pollutant and clean the air.
  • Mechanical air purifier: It comes with a multiple filtration system that includes a washable micro-screen pre-filter that traps dust and other large airborne particles. The True HEPA filter then removes 99.97% of the remaining particles from 0.3 microns and larger.
  • Deodorizer: There is an activated carbon deodorizing filter that helps remove most odors.
  • Humidifier: You also have an option to chose the model with or without a humidifier. So this implies a water tank for the built-in humidifier, it is easy to use and you remove it easily to refill. From what they write you can use ordinary tap water for such a purpose. You have an indicator light that blinks on the control panel when the tank is low.

All in all, this KC-860U removes pollutants and common allergens such as pollen, dust, pet dander and smoke. It also reduces germs, bacteria, viruses, odors, mold, and fungus.
