Air conditioner incorporating
Plasmacluster Ion technology
19 Sharp Annual Report 2008
Creating high-value-added products made with
environment- and health-related technology
Plasmacluster Ion Technology
Plasmacluster Ion technology is a unique technology
equipped in Sharp air purifiers, air conditioners and
other products that purifies the air by removing
airborne mold, viruses and allergens (mite feces and
bodies). The technology is being increasingly
employed in other areas as well, and has now been
used in the products of over 20 different companies,
including shower-toilets and car air conditioners. The
total shipment volume of Plasmacluster Ion generating
units, incorporated in products made by Sharp as well
as those of other companies, amounted to 18 million
worldwide at the end of March 2008. Going forward,
Sharp will expand the range of products featuring this
technology based on the concept of “fill every space
with Plasmacluster Ions.” We also aim to expand
application to medical facilities and public
transportation.
Superheated Steam Oven
Sharp’s superheated steam oven HEALSIO is the first
oven for home use to cook food using superheated
steam technology. The health benefits gained from

■ Efficacy of Plasmacluster Ions Proven in Japan and
Overseas (As of July 2008)
• Test Method: Mite allergens are dispersed into the air of a 1m3chamber and
Plasmacluster Ions are released into the space from a Plasmacluster Ion
generating unit, and the behavior of the allergens measured.
• Eradication Method: Plasmacluster Ions are released into the air.
• Testing & Verification Organization: Graduate School of Advanced
Sciences of Matter, Hiroshima University
Positive and negative ions
cluster on the surface of
airborne mite allergens
A chemical reaction occurs on the
surface, and the ions are
transformed into hydroxyl OH
radicals (powerfully active substance)
The OH radicals remove
hydrogen atoms from the mite
allergen, destroy the protein
and turn into water vapor
The OH radicals sever the
protein on the surface
