Air Purifiers


Humidity levels can make the difference with the air quality you breathe. Sharp's triple action Air Purifier with Humidifier monitors the levels of humidity, dust and odour with a sensor function in a room size of up to 38m². Maintaining 60% relative humidity is ideal for your home and ensures low probability of microorganism growth. The KCA50JW will automatically deliver the right humidity level based on your rooms temperature. While the humdifier ensures the room humidity level is at a comfortable environment, the Air Purification system cleans the air of any airborne substances. This is carried out in two ways, through the HEPA and deodorising filtration system capturing 99.97% of dust particles and using Sharp's patent Plasmacluster Ion technology which helps to deactivate airborne viruses, mould spores, adhering odours and static electricity. Providing clean and breathable air in your home.

Plasmacluster Ion Technology

Reduces allergens, mould spores and viruses, neutralising odours and refreshing the air

Plasmacluster Ion Technology

Plasmacluster Ion Technology

Sharp's patent Plasmacluster Ion technology releases positive and negative ions in the air to reduce airborne substances such as bacteria, mould spores, eliminate odours and refresh the air.

Plasmacluster Ion Technology

How it works

The ions for hydroxide (OH) radicals are highly oxidising when they adhere to the surfaces of airborne microbes like suspended allergens, bacteria, mould and viruses. They remove hydrogen from the surface protiens, breaking them down. The hyroxide (OH) radicals combine with hydrogen (H) to form water (H2O) which returns to the air.

How it works

Advantages of Plasmacluster

Positive and Negative Ions : Deactivates airborne allergens, bacteria, mould spores and viruses.
Positive and Negative Ions : Reduces unpleasant odours at molecule level.
Negative Ions : Refreshes the air by replenishing it with negative ions.

Advantages of Plasmacluster

Effectiveness Proven Worldwide

The effectiveness of Plasmacluster Ions has been proven worldwide at 24 Institutes. Tests are conducted in laboratory conditions using various Plasmacluster Ion densities of up to 50,000 ions/cm3

Maintain the humidity in your home

The recommended humidity level in your home is between 40-60%. If the humidity is above or below the recommended level viruses, bacteria, mould and dust mites are able to easily breed and grow. When the room becomes dry the sensor detects a change in the temperature and humidity level. The humidifying filter will start to rotate, picking up water from the tank and release moisture into the air. When the humidity reaches the desired level the filter is removed from the water and dried by the airflow to prevent mould growth.

Sensor Smart

Sensor Smart

Relax and enjoy breathable fresh air. The built in dust, odour, temperature and humidity sensors will do all the hard work for you. When the sensor recognises a change in the air, the Clean Sign will change colour from green to yellow or red dependng on the serverity of the change. When dust or other airborne particles are detected, the air purifier will increase the fan speed to capture and reduce any airborne substances. When humidity is detected below 40% moisture will be added to the air until the ideal level of humidity between 40-60% is reached.

Efficient and Powerful

Efficient and Powerful

The long collection nozzle based on aerodynamics provides a faster and more efficient air flow. In addition, the Plasmacluster dispersion directs airflow backwards at a 20-degree angle as well as forwards for rapid air purification. This delivers up to 1.5 times higher density of Plasmacluster ions when dispersed into a room for 60 minutes enabling quick removal. The aerodynamic structure quickly collects dust and other particles from low parts of the room.

Allergen Removal

The HEPA filter helps to remove common household allergens such as dust, pollen, pet dander and smoke from the air. The Sharp HEPA filter captures 99.97% of these particles as small as 0.3 microns. The deodoriser pre-filter is to prevent larger dust and dirt particles reaching the HEPA filter and capture any odours drawn through the filter system.

Passive and Active Air Purification

Passive and Active Air Purification

By using both passive and active purification methods, the air is being filtered more effectively and efficiently. The Passive method is based on the HEPA, deodoriser and pre-filter filtration systems. Air is drawn into the system for the filters to capture substances from the air. The Active method cleanses the air by releasing positive and negative ions throughout the room reducing and deactivating airborne substances using Sharp's patent Plasmacluster Ion technology.

Seal of Approval

Seal of Approval

Plasmacluster Air Purifiers are certified from the British Allergy Foundation. The Seal of Approval is for products which restrict/reduce/remove allergens from the environment of the allergy sufferer and for products which have significantly reduced allergen content. When considering which Air Purifier is the most suitable, you will need to consider the room size to ensure the Air Purifier is powerful enough for the room. Assessment carried out by Allergy UK indicate that an individual's exposure can be reduced but this does not mean that an individual's allergic symptoms will necessarily diminish. Allergy UK's opinion applies only to the products and allergens stated. Products should be used only for their intended purpose and strictly in accordance with the manufacturers instructions at all times. The company statements and suggested selling prices are provided by, and are the opinion of only the Manufacturer.

Sharp Air Purifiers

Asthma and allergy sufferers understand the importance of clean air. Animal dander, pollen and many other airborne contaminants cause and exacerbate allergies, particularly in the home. With more of our time spent indoors, reducing these substances from the air around us is important because they can impact upon our wellbeing. Sharp’s Air Purifiers use Plasmacluster technology to help inactivate harmful airborne substances and make our living environment cleaner and healthier.
