Breathe easier with Sharp’s exclusive Plasmacluster™ Technology, a proven air purification innovation that mimics nature to actively eliminate airborne threats in your home or workplace.

In today's environment clean air is a scarcity. Pollutants such as microbes, germs and airborne viruses dominate the environment. This increases the spread of viruses such as the flu which make us unwell.

Sharp's revolutionary Plasmacluster technology was created to help us breathe a little easier. Backed by science, it has been proven to be effective in suspending viruses and microbes that contaminate our air, leaving it cleaner and healthier.

Combined with advanced HEPA filtration, it creates a cleaner, safer indoor environment—ideal for allergy sufferers, asthmatics, families, and pet owners.

A major breakthrough in air quality

Sharp is the world's leading air purifier brand, having surpassed over 100 million units sold worldwide.

What is Plasmacluster Technology?

Plasmacluster is Sharp’s patented air purification technology that releases positive and negative ions—just like those found in forests and waterfalls—into the air. These ions bond with airborne pollutants, such as viruses, bacteria, mould spores, allergens, and odours, breaking them down and neutralising their harmful effects.

Unlike passive filters that only trap particles as air passes through, Plasmacluster actively purifies the air throughout the entire room, reaching even corners and surfaces for 360° protection.

Sharp’s Plasmacluster Air Purifiers are available in a range of models for homes, offices, and shared spaces. Whether you need a compact unit for a bedroom or a high-powered purifier for open-plan living, all Sharp models combine Plasmacluster ion technology, True HEPA filtration, and intelligent air quality sensors to deliver powerful, smart, and silent air cleaning.

Freshens the air with negative ions

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 natural environments such as a rainforest or a waterfall.

Neutralises odour-causing molecules with positive and negative ions

Plasmacluster Ion technology helps reduce the source of a wide range of unpleasant household odours including cooking, pets, rubbish and cigarette smoke

Reduces allergens and mould spores with positive and negative ions

Plasmacluster Ions are helpful in deactivating allergens caused by dust mites, as well as deactivating mould spores that can cause mildew in your home. Sharp Air Purifiers and Ion Generators help to improve the quality of the air you breathe.
