Tests conducted in laboratory conditions using various Plasmacluster Ion densities of up to 50,000 ions/cubic centimetres.

As a result PCI technology has been applied in many industries and in collaboration with other companies Sharp has expanded the Plasmacluster Ion technology to the following industries:




Since the introduction in October 2000 of the first air purifiers equipped with Plasmacluster Ion technology, Sharp’s proprietary air purification technology, total sales of products equipped with this technology reached 60 million units worldwide at the end of December 2015. 

This includes installation of PCI into a lot of Sharp products including Air Purifiers, Humidifiers, Refrigerators, Washing Machines, Vacuums, Air Conditioners, LED Lighting, Ceramic fan heaters, Dehumidifiers and Copiers.
