Sharp PlasmaCluster review: Is this air purifier technology a gimmick?

In this review, we will look at the pros and cons of the Sharp Plasmacluster line of air purifiers. More importantly, we’ll look at the technology it includes and its value relative to the other technologies available. In the attached video you will see me disassemble and enter the Sharp Plasmacluster FPN60CX Air Purifier.

Sharp makes a lot of this “new technology”. Invented by Sharp Corporation in 2000, Plasmacluster technology (and the name) is Sharp’s “claim to fame.” However, it lives on a line between air purifier science and marketing. It is important to know that plasmacluster technology is only one of 4 technologies within the Sharp Air Purifier that we tested. I’d also like to point out that there are a number of similar air purifiers that use almost identical technology, so it’s nothing exclusive. Sharp claims that Plasmacluster technology can inactivate germs and other pathogens and they have conducted 28 experiments across various scientific organizations around the world. However, there have been no recent scientific peer reviews on this yet.

Enthusiasm for Sharp Plasmacluster stems largely from Japan, where an aversion to germs and viruses has made Sharp air purifiers popular. (Designed in Japan, made in China).

What is a plasmacluster?

A Plasmacluster ion generator splits water molecules (already in indoor air) into their natural components of hydrogen and oxygen (remember water is H2O). Thousands of these positive and negative ions are released in this process. These ions are very unstable and do not last long. They can remove nicotine and other unpleasant odors from the air and kill some mold spores and viruses. Many air purifiers use negative ions in the same way, but the positive ion part is more exclusive.

    Here is a more scientific explanation:

A plasmaluster is a group of partially ionized gas-like electrons (have I lost you in scientific terms yet?) that are free and not bound to an atom. These plasma pools contain water molecules that disintegrate into both positive hydrogen ions and negative oxygen ions. Water molecules naturally found in room air form clusters around hydrogen ions and oxygen ions; this creates the stable Plasmacluster ions. When they hit pathogens (germs, viruses) they lead to the instantaneous formation of the highly unstable/reactive hydroxyl radical. Such mercurial composition causes hydroxyl radicals to rapidly interact with hydrogen atoms on the surface membranes of pathogens. And the result; inactivated pathogens and a harmless by-product, water.

HEPA and Plasma cluster

Of course, Plasmacluster is just one of the technologies in the air purifier. It also has HEPA (which is too expensive by the way) and carbon for gas removal. So is the Plasmacluster up there with the “must have” and is it better than using negative ions and ultraviolet light to kill germs and viruses? That debate is still ongoing and has not been tested. Below I list some of the technical information about the Sharp FPN60CX


1 – 4 stages: Prefilter, Carbon, Hepa, Ion (PLasmacluster)
2 – Hepa for allergies
3 – Covers 330 square feet
4 – It has excellent light functions: you can sleep without lights on


1 – Expensive filters
2 – Expensive cost
3 – No Germ, Virus Tech (EX; UV)
4 – 1 year warranty
5 – On high the unit is noisy

Sharp FPN60CX Air Purifier
Retail Price: $379
Purification technologies: 4
Square Feet: 330 SQ. Foot.
Filter replacement costs: $180 (HEPA and carbon)
Annual costs: $180-$200
Decibel level: low/high 14/54

Other models:


It’s a good air purifier, and you should be able to get your money’s worth out of the sharp plasmacluster. Replacement filters are too expensive (let’s make it too expensive), and I’d look for better prices online for replacements. However, it will do a good job with pollen and dust.
