Claim 2:
3. The system of claim 1, wherein the second preprocessing member comprises a first high-voltage discharge member, an adsorption member and a second high-voltage discharge member inside a housing, so that the polluted air containing harmful materials is ionized with a covalent bond of a harmful material molecule dissociated in a process of high-voltage discharge and is then adsorbed onto an adsorption material loaded on a carrier of the adsorption member so as to purify the polluted air, and then to sterilize bacteria and variant viruses in air, which are introduced, with free radicals including superoxide anion (O2-), hydroxyl radical (OH-radical), nitrogen monoxide (NO), singlet oxygen (102), in which an oxygen ion (O) generated by dissociating a covalent bond of nitrogen (N2), oxygen (O2) and a water molecule (H2O) of water vapor, which are constituent materials of purified air, is bonded with oxygen in an unstable form.
