Sharp Introduces Three New Humidifying Air Purifiers for Fiscal 2007

Combines Twin Plasmacluster Ion Power (KC-C150), a First in a Home Unit*1,
Plus Newly Developed 20° Angled Outflow Duct

Quickly Eliminates Odors and Removes Allergens Such As Household Dust,
Pollen and Dust Mites

Sharp Corporation will introduce into the Japanese market three new humidifying air purifiers that powerfully remove allergens such as airborne household dust, pollen and dust mite particles as well as lingering adsorbed odors using a combination of Twin Plasmacluster Ion Power based on dual Plasmacluster Ion generators, a first in a home-use unit, and a newly developed 20° Angled Outflow Duct.

Using a combination of Twin Plasmacluster Ion Power that dramatically increases the volume of Plasmacluster Ions generated, and a 20° Angled Outflow Duct that accelerates air circulation in the room for more efficient dust extraction, the KC-C150 quickly and powerfully removes house dust and pollen at twice the speed of the predecessor model*2. These models also quickly decompose and eliminate allergens such as dust mite particles. They also feature a powerful deodorizing function that eliminates even odors clinging to curtains and walls. Plus, a full-fledged humidifying function with the industry's highest*1 humidifying capacity of 760 mL/hour (KC-C150), powerful enough for a living room up to 35 m2, creates a pleasant environment that helps keep house dust and pollen from drifting in the air. And, the adoption of a proprietary rotating filter disc humidifying mechanism doubles*3 the service life of the humidifier filter.

Dust mites and house dust are said to be the cause of 80% of allergy-related illnesses. In this light, Sharp is offering this new series of air purifiers to provide a clean indoor environment all year round thanks to full-fledged humidification, new angled outflow duct, and its proprietary Plasmacluster Ion technology, now more effective than ever.

Development Background
Conventional approaches to removing dust, pollen and dust mite particles in the home include ventilation, vacuum cleaning, and wiping with a dust cloth (at least once a week).
However, the reality is that many consumers cannot adequately put these approaches into practice for reasons that include "no time," "takes too much effort," "can't keep up the effort for long" etc. (according to Sharp research).
As a result, consumers are seeking air purifiers--the most appropriate way to deal with household dust, pollen and dust mite particles--that can keep the indoor environment clean with a minimum of effort all year round.
In addition, it is widely recognized that raising indoor humidity is effective in controlling drifting household dust and pollen as well as minimizing the drying of the mucous membranes in the nose and throat. Therefore, an increasing number of people are also seeking an air purifier equipped with a humidifying function.
Thanks to the combination of Twin Plasmacluster Ion Power and a new Angled Outflow Duct, Sharp is offering an air purifier that quickly removes household dust (suspended dust particles) and powerfully decomposes and inactivates floating dust mite particles, a major cause of allergies.




Outstanding Features

1. Combination of Twin Plasmacluster Ion Power (KC-C150) and newly developed 20° Angled Outflow Duct improves air purifying power
1) Quickly extracts suspended household dust and pollen twice as fast (KC-C150) as the predecessor model. Also decomposes and eliminates allergens such as dust mite particles
The model KC-C150 is equipped with two Plasmacluster Ion generators for Twin Plasmacluster Ion Power that dramatically boosts the volume of ions generated, plus all models feature a newly developed Long and Wide 20° Angled Outflow Duct with a funnel-shaped nozzle designed using the principles of aerodynamics. This design enhances blown air efficiency and minimizes reductions in airflow velocity, plus applying the principle of providing a greater length of air contact along wall surfaces (Coanda effect) makes the blown air circulate more rapidly throughout the entire room. In addition, a Rear Panel Intake Grid on the back of the cabinet allows room air to be drawn into the unit efficiently. In combination, these features enable household dust and pollen to be extracted from the air at a rate approximately twice as fast as the predecessor model (KC-C150). And these models also powerfully decompose and eliminate allergens such as dust mite particles.




2) Powerful deodorizing of clinging odors. Also neutralizes static electricity generated under dry conditions at double*4 the speed of the predecessor model (KC-C150)
Twin Plasmacluster Ion Power creates a powerful deodorizing action for odors that cling to curtains and furniture such as couches. In addition, static electricity generated when the air is dry is neutralized at a speed double that of the predecessor model KC-51C1, reducing the tendency for household dust and pollen to adhere to clothing, furniture such as couches, etc.



2. Nine-level Dust Monitor provides a visual indication of the amount of household dust being captured (KC-C150/C100)
The Dust Monitor uses a dust sensor to monitor the room environment for airborne dust particles and provide a visual indication of how much household dust is suspended in the air. The lights on the monitor display panel change color to indicate nine levels of air cleanliness, showing at a glance the level of impurities in the room air, and confirming that the air is being adequately cleaned.



3. Full-fledged humidifying with a capacity of 760 mL/hour (KC-C150), the industry's highest. Plus, a proprietary rotating filter disc humidifying mechanism doubles the service life of the humidifier filter.
Full-fledged humidifying with a capacity of 760 mL/hour (KC-C150), the industry's highest*1, is capable of handling large living spaces up to 35 m2 in area to create a pleasantly moist indoor environment that minimizes suspended dust and pollen floating in the air. Further, the adoption of a proprietary rotating filter disc humidifying mechanism maintains humidity in the entire room while air purifying is going on. As the air is being purified, the filter disc automatically starts and stops rotating according to the humidity conditions in the room, creating a comfortable environment. This feature also helps protect the nose and throat from dryness, and even suppresses the activity of viruses.

In addition, the use of a rotating filter disc for humidifying ensures that the water is distributed uniformly over the entire filter, thus maintaining humidifying performance and extending the service life of the filter to double that of the predecessor model*3. Plus, when the humidifying feature is not in operation, the humidifying filter disc is automatically stopped in a position where it is not immersed in water, keeping it dry and ensuring that it will always be sanitary and hygienically clean when used.



4. Filter design ensures high performance over the long term. Plus simple, easy care
  • For improved dust extraction performance, these models feature a new Micron Mesh Preliminary Filter to capture dust particles larger than approximately 500 µm in size. It is designed to prevent dust particles from penetrating into the high-performance dust filter (anti-bacterial*5 HEPA filter) and keep performance losses in this filter to a minimum. Also, the surface of the Micron Mesh Preliminary Filter is coated with a fluorine-containing polymer resin, allowing adsorbed dust particles to be cleaned simply and easily.
  • The high-performance dust filter is an anti-bacterial HEPA filter capable of extracting more than 99.97% of dust particles 0.3 µm in size. It also works to minimize the activity of allergens*6 and viruses*7 such as pollen (removes 99.9%) and dust mite particles (removes 99.9%), etc.
  • The deodorizing filter is washable, and its ability to remove odors can be restored simply by regular washing using clean water. Thus, it never needs to be replaced.
  • In addition, the humidifying filter features enhanced anti-bacterial*8 and fungicidal (anti-mold)*9 capabilities, and is designed to prevent reduced humidifying performance resulting from contamination or lime deposits (hard-water scale). It is also simple and easy to remove, and the entire filter unit can be washed, ensuring that sanitary humidifying is always available.

    Motivation for Explaining the Mechanism
    Since the successful development of Plasmacluster Ions in 2000, Sharp has worked with authoritative independent organizations at the cutting edge of their fields to scientifically prove the effectiveness of these ions in suppressing various types of bacteria, viruses and allergens. However, myriad types of these harmful airborne substances exist, and testing the effectiveness of Plasmacluster Ions against all of these individually would be difficult and time-consuming. That is why Sharp has been working to elucidate the suppression mechanism, which lies at the root of their effectiveness. Thanks to the success in explaining the suppression mechanism against mite allergens, the suppression mechanisms against all sorts of harmful substances that have thus far been demonstrated have come to be understood. Through this mechanism explanation, it became clear that the effectiveness of Plasmacluster Ions against a wide range of harmful substances could be anticipated.


    Working Mechanism for Plasmacluster Ions
    It has come to be understood that the working mechanism for Plasmacluster Ions against bacteria, viruses and allergens is that positive and negative ions surround them, and OH radicals generated from the ions damage their structure by fragmenting and decomposing proteins on their surfaces.
