Tiny in size but not in might aptly describes the little dynamo at the centre of Plasmacluster Ion technology. Our Sharp air purifier review will now highlight the enhanced high concentration Plasmacluster Ion generator. Whilst it measures only 57mm by 28.5mm by 15.5mm, this generator is responsible for the reactive agents, without which the air purifier is worthless.

Overview of Plasmacluster Ion Technology

By the application of positive and negative voltages to discharge electrodes in the Plasmacluster Ion generator, plasma is formed. After solid, liquid and gas, the three commonly known states of matter, there is a fourth, plasma. Existing in a partially ionized gaseous form, plasma is a mixture of atoms, molecules and free electrons that are not bound to either. The decomposition of water molecules that exist naturally in plasma result in positive ions (hydrogen) and negative ions (oxygen). Distinct and stable Plasmacluster Ions are created when atmospheric water molecules form clusters around the hydrogen and oxygen ions. Ultra reactive and extremely unstable hydroxyl radicals are created as soon as Plasmacluster Ions come into contact with any pathogens. This characteristic causes the hydroxyl radical to combine with hydrogen atoms on the surface membrane of the pathogen. Incredibly, the product is a deactivated pathogen and a harmless by-product, water. Simply perfect! But is it fact or fiction?

Plasmacluster Ion – Science Fiction or Scientific Fact?

A genuine Sharp air purifier review has to resolve the most basic doubt – are Plasmacluster Ions fiction or scientific fact? As with many other products emerging from the field of nanotechnology, Plasmacluster Ions are invisible to the naked eye. Compounding the issue, the individuals who use air purifiers have no means to validate the claims. Obvious alternative authentication means would be to rely on tests results of Plasmacluster Ion experiments. This is done in 2 ways, in the laboratory (efficacy test) and in the real world (efficiency test).

Sharp, consistent with its long track record of achievements, scores again in having anticipated these valid concerns. Developed almost into an art by Sharp is the concept of academic marketing. Working in conjunction with reputable academic institutions, Sharp subjects its claims regarding Plasmacluster Ions to the scrutiny of reputable scientists. Scientific data produced by academia becomes the basis for introducing new products by Sharp. Two separate approaches to effectiveness, efficacy and efficiency, is being pursued by Sharp. The years between 2000 and July 2009 has seen Sharp focusing on efficacy testing. Moving to center-stage currently is efficiency testing, typically conducted on the premises of business end users of Plasmacluster Ion technology.

Plasmacluster Ion – Authentication at Cellular Level

Digging deeper for this Sharp air purifier review, we discovered that Sharp is doing its utmost in efficacy and efficiency testing so as to be outstanding in the industry. On 17 November 2004, Sharp announced the results of studies by Professor Gerhard Artmann of the Department of Cell Biophysics and Bioengineering, University of Applied Sciences, Germany. Through the use of an electron microscope, Professor Artmann (a cellular engineering expert) verified that Plasmacluster Ions damaged more than 60 proteins on the surface cell membranes of pathogens leading to inactivation of both viruses and bacteria.

That the pathogenic cell DNA is unaffected by Plasmacluster Ions which do not puncture the cell membrane is of great importance. Unlike other competing air purifiers which rely on DNA destruction to be effective, an advantage is claimed here by Plasmacluster Ions technology. The danger to users of other air purification technologies being exposed to cancer from DNA damage was implied.

Plasmacluster Ion – Efficacy Tests

This current Sharp air purifier review puts together some of the efficacy tests on pathogens performed by Sharp together with many organizations. Conducted over the years from September 2000 to July 2009, the tests have proven that Plasmacluster Ions are effective in removing 28 kinds of harmful airborne microorganisms. Of the virulent microorganisms, the most important ones are MRSA (notorious for causing mortifying infections in hospitalized patients), the terrifying SARS virus, the potentially deadly H5N1 avian flu virus and a variant of the H1N1 virus that surfaced in Mexico in 2009.

The polio virus and the coxsackie virus which causes the common cold are also destroyed by Plasmacluster Ions. Also annihilated are candida, pseudomonas, serrata bacterium, sarcina, escherichia coli, bacillus subtilis, micrococcus, enterococcus, white staphylococcus and staphylococcus. A whole range of fungi (alternaria, aspergillus, cladosporium, mucor, penicillium, stachybotrys) are also effectively destroyed together with pollen, mites and other allergens.

Many organizations, counting among them some prestigious names, worked with Sharp; including:

- Retroscreen Virology, Ltd., London, UK

- Harvard School of Public Health, USA

- University of Lübeck, Germany

- Asthma Society of Canada

- Seoul University, Korea

- CT&T, Aachen University of Applied Science, Germany

- Shanghai Municipal Center for Disease Control and Prevention, China

- Kitasato Institute, Medical Center Hospital, Japan

- Kitasato Research Center of Environmental Sciences, Japan

- Ishikawa Health Service Association, Japan

- Graduate School of Advanced Sciences of Matter, Hiroshima University, Japan

The last reported efficacy test was reported on 27 July 2009 involving the Osaka City University Medical School validating the inhibitory power of Plasmacluster Ions on allergic reactions caused by mite allergens or mite dust (mite feces and dead mites).

Wrapping up our Sharp air purifier review in relation to efficacy testing, we would highlight that a key factor is that they were conducted by organizations which have attained GLP (Good Laboratory Practices) status, an OECD guideline that attests the reliability of tests results produced. GLP status is renewable on a 3-year basis. A critical piece of information yet it is often disregarded by the critics of air purification technologies and academic marketing. Curiously, the fact that test data generated by a GLP laboratory can be readily peer reviewed by fellow scientists is also disregarded. As we know, the scientific peer review is the missing final jigsaw piece in the puzzle of all air purification technologies, Plasmacluster Ion technology included!
