Abstract
An air cleaning apparatus includes a fan assembly configured to induce a vortex extending in front of the air cleaning apparatus for extracting air from a targeted region to remove and inactivate airborne pathogens (e.g., viruses) in the air. The air cleaning apparatus includes a reactor core configured to inactivate airborne pathogens via contact with anatase coated plates activated by UVC light. The air cleaning apparatus includes a filter assembly for removing reactive oxygen species in the decontaminated air.
Claims10
A method for disinfecting an airstream containing microorganisms by electrostatic precipitation by passing the airstream through the space between at least one grounded collection plate having at least one electrode spaced apart therefrom connected to a source of electric potential, wherein the method comprises:
- extracting the airstream from a targeted area by creating a vortex of negative pressure above the targeted area;
- contacting the airstream with a photocatalyst having a predetermined band gap energy coated on the surface of each grounded collection plate and illuminated with photons having a wavelength corresponding to the band gap energy of the photocatalyst, so that at least a portion of the microorganisms that collect on the grounded collection plate are destroyed by photocatalytic oxidation.
An air cleaning apparatus comprising:
- a housing;
- a fan configured to extract an airstream from a targeted area and into the housing;
- and
- an electrostatic precipitator positioned upstream of the fan and configured to filter particulates greater than 10 microns in size;
- wherein the electrostatic precipitator includes at least one plate coated photocatalytic titanium dioxide nanoparticles.
