Plasmacluster Day

What Is Plasmacluster Day?

November 11th is "Plasmacluster Day" in Japan. The date comes from likening the positive (+) and negative (-) ions central to Plasmacluster technology to "juichi" (eleven, read as "plus, minus"). It was established by Sharp Corporation.

A Technology Holiday That Maps Ion Function Onto Numbers

Plasmacluster is Sharp's proprietary technology that releases positive and negative ions into the air to help suppress airborne mold and viruses.

• Origin: the "positive ions" and "negative ions" at the heart of Plasmacluster technology are likened to "eleven" (read as "plus, minus")
• Purpose: to help more people understand how Plasmacluster technology works and what it does
• Expanding applications: found not only in air purifiers, but also in air conditioners, refrigerators, and in-car devices

Invisible Ions That Change the Quality of Air

Plasmacluster ions contain OH radicals surrounded by water molecules, said to act on airborne germs and odor-causing substances. Because the technology itself is invisible, understanding how it works adds real meaning to it.

Tips for Marking This Day

• Check the features of your home's air purifier or air conditioner
• Look into how Plasmacluster technology works
• Take a fresh look at your indoor air environment
• Think about seasonal air care, from humidification to ventilation

Invisible Ions Quietly Improve the Air Around You

Because this technology is invisible, understanding how it works brings a greater sense of reassurance to daily life. November 11th is a day to take a fresh look at the air quality around you.
