Using negative ions, Sharp Air Purifiers and Ion Generators help to clean and refresh the air. Sharp's range of Air Purifiers and Ion Generators release negative ions creating a "feel good" atmosphere similar to naturally occurring environments like a rainforest or near a waterfall. Plasmacluster Ions break down and remove projecting spike-shaped proteins of suspended viruses such as influenza, reducing their effects. The air we breathe is a basic human necessity, playing a vital role in our health and general well-being. However, in today's environment, unpolluted, fresh, clean air is scarce, as pollutants such as microbes, germs, and airborne viruses dominate, increasing the spread of flu and other viruses that make us feel ill and unwell. Sharp's revolutionary Plasmacluster technology has been proven to be effective against suspending viruses and microbes that contaminate our air, leaving the air cleaner and healthier.
