1. A multi-function air purifying and sterilizing system for sterilizing air comprising:
a casing having an air inlet at one end of the casing and an air outlet at the other end of the casing with an air stream direction from the inlet to the outlet,
electrostatic members each of which having at least one opening, the opening comprising at least one spiked surface which extends substantially perpendicular or substantially parallel to the air stream direction, said at least one spiked surface inducing corona discharge and/or cold plasma when high voltage is applied, said corona discharge and/or said cold plasma producing ozone molecules,
at least one energy source for producing rays, said at least one energy source is inter-displaced within said electrostatic members to have the produced rays in proximity to said electrostatic members for:
(a) maximizing said at least one energy source efficiency in demolishing said particulate matter and/or said biological contaminants depositing on said electrostatic members,
and/or
(b) converting said ozone molecules to hydroxyl radicals, said hydroxyl radicals disinfecting and inhibiting said biological contaminants and/or odors, and/or gases in said air stream and/or in a confined space,
wherein some electrostatic members operating at a first voltage are collecting members, while other electrostatic members comprised of at least one spiked surface operating at a second voltage are repelling members, said at least one spiked surface inducing corona discharge and/or cold plasma when high voltage is applied, said corona discharge and/or cold plasma producing ozone convertible to an hydroxyl radical via UV light or ultraviolet light or X-rays or Gamma-rays, or Alpha-rays,
said hydroxyl radical disinfects and inhibits biological contaminants,
thereby, said multi-function air purifying and sterilizing system either filtering and sterilizing the air via said electrostatic members and/or producing ozone molecules convertible to hydroxyl radicals for disinfecting and inhibiting said biological contaminants and/or odors, and/or gases in said air stream and/or in said confined space; and
wherein said electrostatic members are comprised of a series of electrostatic members, wherein said series of electrostatic members is configured to extend parallel to the direction of the air stream, each of said electrostatic members having at least one opening to allow at least one ultraviolet lamp to be disposed therethrough.
