Is air purifier good for health, and why?
Is an air purifier good for health? Do I need an air purifier since I clean my house every day? These questions have been asking by many of us for a long time.
Air pollution level is increasingly high as the cost of heavy industrial revolution. Do you think that solely staying home could protect you and your family from exposure to these harmful gases and pollutants? You might be wrong.

According to the Environmental Protection Agency (EPA), there are 2-5 times higher chemical pollutants in indoor air than those found in outdoor air!
Your home is your heaven, but pollutants and harmful gases will still seep into your house and cause respiratory illnesses and allergic reactions.
That's why you might need an air purifier, but the RIGHT one.
All You Need to Know About Air Purifier
Be it in any shape and design; an air purifier is an indoor device that absorbs and filters harmful particles from its surrounding.
An air purifier is primarily used to purify the surrounding air and improve air quality. This can limit the spread of harmful particles and allergens to prevent respiratory diseases or allergy problems in humans. The device is widely used in homes, offices, learning centers, and hospitals.
Common Indoor Pollution Problems
Hidden in your house could remain a wide variety of invisible contaminants. Be it allergens, haze, bacteria, and viruses, as well as odors and dust that are invading from outdoor.
Common indoor problems are often relating to air and odor pollution:
Plant-based allergens such as pollen will cause allergic reactions. Other allergens such as house dust, mold, and dust mites are common problems in almost every household.
Odors normally come from pets, cigarettes, and food.
Contaminants and germs such as bacteria and viruses will cling to people and carry them home from outside. Also, a sick family member who sneezed or coughed will cause the germs to spread inside the home environment.
Many volatile organic compounds (VOCs) are human-made chemicals used and produced for the manufacture of pharmaceuticals, paints, and refrigerants.
VOCs include various chemicals, some of which may have short- and long-term adverse health effects.
Especially the air in a closet, many clothes that are kept in that small, closed place could cause an unpleasant odor to linger around the room.
Air purifier is good for health if chosen RIGHTLY
The main point here is that the air purifier should be chosen RIGHTLY if your utmost purpose is to purchase it for you and your family's good health.
- Plasmacluster technology  - Plasmacluster ion generator discharge and emits the same positive and negative ions that occur in nature. Plasmacluster technology is Sharp’s original air purifying technology that removes airborne mold and viruses.
- HEPA filter is the 'king'
HEPA filter-based air purifiers produce no harmful by-products. They can effectively remove allergy-causing and toxic substances from the air, leaving only fresh air behind.
You often came across the word 'HEPA,' but what is HEPA? It stands for 'High-Efficiency Particulate Air (filter).
- Strong suction and Coanda airflow
Powerful air suction and unique airflow quickly and efficiently collect dust and other particles.
Scientifically Proven Benefits of Purifier
Based on Marilia Coutinho, a Brazilian researcher, there are enormous scientific research that have proved the effectiveness of air purifiers.
Let the Science Talk
- Reduced morbidity and mortality
Based on the study of W.J. Fisk, reduced morbidity and mortality due to reduced exposure to harmful particles from outdoor air is the largest potential benefits of indoor particle filtration.
- Improved endothelial function
Another recent study concluded that air filters had reduced indoor fine particle concentrations by 60%.
This study compared the health effects with or without HEPA purifiers. As a result, they concluded that air filtration was correlated with improved endothelial function* and decreased inflammatory biomarkers concentrations.
*Endothelium- a thin layer of single flat cells that line the interior surface of blood and lymphatic vessels
- Improvement in lung function
The First Nation's encouraging finding suggested reducing indoor fine particulate matters (PM2.5) with an air filter may improve lung function.
Summary: Are air purifiers good for your health?
In Short, the answer is a 'Yes' if you have chosen the right purifier. One thing we can confirm is air purifiers can reduce the levels of indoor PM2.5 with a wide range of health improvements.
Sharp’s Plasmacluster Ion Technology has been proven by test data worldwide to provide pure, healthy, safe air for homes and various industries. Sharp’s patented Plasmacluster air purifying technology removes airborne mold and viruses by generating positive and negative ions.

High-density Plasmacluster Ions Air Purifier
Exclusive air purifying technology from SHARP
- With Sharp’s proprietary Plasmacluster ion (PCI) technology, positive and negative ions are discharged when the air purifier is switched on. These ions deactivate airborne contaminants by attaching to them while extracting a hydrogen compound to break down the protein membrane, resulting in water molecules, which are returned to the air.
- Plasmacluster Technology emits more positive and negative ions in a room than even those found in a forest. It is proven to be safe and highly effective, no matter how high the ions' density is.
- Plasmacluster is thus increasingly finding applications in various areas of activity, such as in businesses, in addition to household use.
High Density 7000, 25000 & 50000 (NEXT)+ 
Different ion density provides different level of benefits. Plasmacluster air purifier with ion density 7000 can purify the air, remove odors, and reduce static electricity.
Meanwhile, Plasmacluster air purifier with ion density 25000 can do a lot more than purifiers with ion density 7000. The functions include but are not limited to air purifying, odors removal, and static electricity reduction. Also, it is capable of suppressing the adhering viruses, mold fungus, and pollens. Strong odors like tobacco can be removed as well. This kind of air purifiers tends to have a 5x elimination speed compared to those with ion density 7000, thus making skin-beautifying effective.
High-Density NEXT purifiers are way more powerful. It produces ion density 50,000. Other than the listed effects above, these purifiers can create a less stressful environment that is easier to maintain the ions' concentration. Pet owners are advised to have a purifier with High-Density NEXT in home since they can suppress bacteria that cause pet skin disease. Removal of odor-causing bacteria and adhering excrement odor are also what High-Density NEXT purifiers are capable of. In conclusion, these purifiers have more purification ability compared to Plasmacluster air purifiers with ion density 7000.
* Note: Above data are verified under the test condition. The effects may differ depending on the actual usage/environment.
* The number in this technology mark indicates an approximate number of ions supplied into air of 1 cm3, which is measured around the centre of the applicable room floor area (at 1.2 m height above the floor) when the product is placed close to a wall at the MED mode setting.
