Having initially posted about this machine I bought, I see a lot of people searching for information about Sharp’s Ion plasmacluster and thought it would be useful to add some more information about this.

Original Post
The original post I did can be found here at shibuya246.com

According to the pamphlet, Plasmacluster technology emits positive and negative ions into the air, and thereby deactivates impurities. They are designed to combat dust, allergens, pollen and other air borne particles such as tobacco smoke, cold viruses etc.

My experience
I bought the machine because hearing that influenza was going to be widespread this year, I really wanted to make sure I did not catch it and so far I have not had a cold. I have used the machine non-stop since I bought it and found it easy to use, fairly quiet and of great value.

The machine I bought covers about a 6-8 tatami mat area. Outside of Japan I am not sure what size that translates to, but it is an average size Japanese room and probably an average size western hotel room. The space of 1 tatami mat was meant to be the space required for one person to sleep lying down. Without digressing too much here is a link to Wikipedia talking about Tatami

Sharp installing units in own offices
Recently Sharp announced that they would be installing 10,000 of their industrial plasmacluster machines in their Sharp offices and factories.

The above articles discuss the larger industrial units where Sharp says:

Plasmacluster Ion generators use Sharp’s proprietary Plasmacluster Ion technology to decompose and deactivate harmful airborne substances such as mold fungus, viruses, and allergens. These generators are designed to thoroughly deactivate harmful airborne substances in large areas, such as offices and conference rooms.

Although the technology for the smaller units is the same, just they dont cover as large an area.

Technology Explanation
Here is an easy to understand article about the technology with some pictures to aid the explanation:

Sharp announce Bird Flu tests
In a conference focussed on plasma cluster technology,the ability to handle “bird flu” was discussed.

This machine is hot and was just released in Japan last month.

I recently purchased a Plasmacluster Ion machine from Sharp. According to the maker the machine “emits positive and negative ions into the air, thus deactivating impurities.”  This is different to a humidifier which just releases steam into the air. Sharp have a number of patents for the technology this machine is based on. They have also released hybrid machines that act as plasmacluster and humidifiers, but I was told by staff at BicCamera that the machine IG-A100 Plasmacluster was the full model whilst the hybrid machines were more like an introductory model. The IG-A100 machine gives out 25,000 Ion clusters per cm cubed. It cleans the room from dust mites, virus particles and mold spores. This is different to conventional air filters or air purification machines.

According to the Sharp website the machine “Plasmacluster Technology splits water molecules into positively and negatively charged ions, which spread throughout the room, surrounding airborne particles. This system effectively treats the air the way nature cleans the environment near waterfalls or just after a thunderstorm to help keep the air healthier and cleaner smelling.”

Anyway, the result is a very pleasant environment which smells fresh and clean. Here is a picture of my machine in my apartment.

and some links to Sharp’s site talking about the technology




Above is Sharp’s logo for the Plasmacluster Ion product range. They use this on their hybrid machines also, but be sure to check the Ion count the machine is putting out. that seems to be the key to the effectiveness of the machine.

I did an update to this post that can be found here
