Sharp Air Purifiers Compared FPK50UW vs. FPF60UW vs. KC850U vs. KC-860U

What is Plamacluster technology

Sharp's revolutionary Plasmacluster technology has been proven to be effective against suspending viruses and microbes that contaminate our air, leaving air cleaner and healthier.

Plasmacluster Technology – this technology is one kind of ionizer, which can further reduce the number of pollutants. It can be switched on/off. With this technology device can emit both positive and negative ions into the air, to form hydroxyls that decompose the protein and suppress the activity of the viruses. This technology can even remove static electricity.

What is the True-HEPA filter

HEPA is an acronym that stands for High-Efficiency Particulate Air. This is a pleated filter that traps airborne particles as they pass through an air purifier. A true HEPA filter removes 99.97% of all particles that are 0.3 microns in size or larger. This is known as the HEPA standard. Although, in marketing see HEPA as a term to mean in general a high-efficiency filter.

Let’s start with what it means to be a true HEPA filter, how filters are measured, and the purpose or use.

The purpose of the HEPA filter is to remove both large and small particles from the air. The lightweight of the small particles allows them to suspend in the air for long periods of time. This is what you breathe into your lungs.  The smaller particles cause the most problems to your respiratory system as well as allergic reactions.

The larger and heavier dust type particles will settle to the ground much more quickly. They are harmless to your system.  Some of the larger particles include pet hair and some pet dander.  Although to get rid of all pet dander you need to remove the small airborne particles as well.

Each purifier also has a washable pre-filter that traps bigger particles.

What is an activated carbon filter

Activated carbon has special properties that allow it to remove volatile organic compounds (VOCs), odors, and other gaseous pollutants from the air. 

Carbon air filters are the filters most commonly used to remove gases. They are designed to filter gases through a bed of activated carbon (also called activated charcoal) and are usually used to combat volatile organic compounds (VOCs) released from common household products. They are also often used to remove odors from the air, such as the smell of tobacco smoke. They cannot remove fine particles like mold, dust, or pollen from the air.
