19. An aseptic and odorless nitric oxide generator according to the present invention removes harmful materials such as ozone (O3), nitrogen dioxide (NO2) and the like, which are generated during discharge from a high-voltage discharge unit, by contacting the same with respective catalysts at a catalytic reaction unit, reduces noise, which is generated in a discharging process, by using a sound-absorbing material provided inside a vent pipe, and receives measured data from respective sensors provided inside the vent pipe so as to allow a control unit to execute and automatically operate a feedback control, thereby supplying and circulating indoors the air containing aseptic and odorless high-quality nitric oxide, and thus is very appropriate for the nitric oxide absorption of a person residing indoors through the mouth, the skin and a breathing process.
