Technology Used

There is various type of Filterless Air Purifiers named after the technologies they each employ to clean the air. These are ionization, Electrostatic precipitator, Photocatalytic oxidation, Thermodynamic sterilization, Ultraviolet light, and Ozone generator.

Air ionizers work by creating an electrical static field that primarily charges the airborne particles. These charged particles drop and attach themselves to the nearest surface. This could be on the walls, seats, floor, tables’ carpets, or even beds. Once they embed on any surface, you are required to do vacuuming of the house to clean the fallen particles.

Electrostatic Precipitators works the same way as Ionizer. However, they have an added collector plate. With its high voltage electrostatic field, it removes airborne particles. The collector plate, in turn, attracts the heavier electrostatic charged ions particles that fall off.

Photocatalytic oxidation is a technology developed by NASA. The technology employs photocatalysis combination reaction of broad-spectrum UV light and titanium dioxide to eliminate harmful pathogens in the air.

UV Air Purifier emits a broad wavelength of electromagnetic UV radiation to disinfect bacteria, viral viruses, and other pathogens from reproducing.

Thermodynamic sterilization is a technology that sterilizes 99.9% of bacteria, viruses, and other microorganisms through high temperatures over 400°F.
