A Remarkable Air
Purifying Mechanism

Sharp's revolutionary Plasmacluster technology has been proven to be effective against suspending viruses and microbes that contaminate our air, leaving air cleaner and healthier.

Plasmacluster technology generates and emits the same positive and negative ions that occur in nature. After purifying the air, the ions turn to water and return to the air.

Sharp is constantly developing new ways that Plasmacluster can bring benefits to society.


How it works


Plasmacluster Ions are similar to positive and negative ions found in nature. The ions are surrounded by water molecules and are released into the air.


The ions from hydroxide (OH) radicals are highly oxidising when they adhere to the surfaces of airborne microbes, such as suspended allergens, bacteria, mould and viruses. They remove hydrogen from the surface proteins, breaking them down.


The hydroxide (OH) radicals combine with hydrogen(H) to form water (H20) which is returned to the air.


Providing you with fresh air and a healthy environment

Positive and negative ions make air clean
and life comfortable.

Purifies air

Eliminates airborne mold and suppresses activity of adhering viruses, bacteria and allergens.

Eliminates odors

Breaks down and eliminates adhering odors from tobacco smoke, cooking smell and pet odors.

Reduces Static Electricity

Plasmacluster ions reduce static electricity, preventing pollen and airborne dust from clinging to curtains, clothing and other surfaces.

Beautifies skin

Water molecules produced by PCI adhere to the surface of the skin, forming a coating which maintains moisture of the skin.

Plasmacluster on SHARP Products

With Plasmacluster technology on every Sharp product, it can bring the freshness and comfort at all times.

Sharp Air Purifiers contain a Plasmacluster Ion Generator that releases positive and negative ions into the air. The Plasmacluster Ions diuse through the room, surrounding airborne allergens, bacteria, mould and viruses, converting hydrogen molecules in their surface proteins into water.

Sharp Air Conditioners does not compromise clean air. With Sharp Plasmacluster Technology built in the Sharp Air Conditioner, positive and negative ions are discharged when the air conditioner is switch on. Plasmacluster suppresses airborne virus and bacteria, airborne and proliferating mould, unpleasant odour and allergens such as dust mites and faeces.
