Patent abstract
The air clarifying apparatus includes a negative ion generator and an indoor air circulator. It further includes an ozone generator having a capability of maintaining the average concentration value of ozone in an indoor atmosphere at 0.02 to 0.05 ppm, while the average concentration value of negative ions in the vicinity of the blowout port of the negative ion generator is maintained at 200,000 to 1,000,000 pieces/cc. With this configuration, the negative ions coexist with ozone having a low concentration.
