Attorney, Agent or Firm:
An air-purifying apparatus comprising: a main body having an intake portion and an outlet portion; a blower disposed in the main body and adapted to induce the ambient air through the intake portion and to forward the air to the outlet portion; and a high-voltage generating means mounted in the main body; wherein the intake portion includes a intake grille, first and second net-shaped electrode plates disposed along the inner side of the intake grille and opposing each other with a large potential difference developed therebetween by the high-voltage generating means, the first net-shaped electrode plate being remoter from the intake grille than the second net-shaped electrode plate, and an air-permeable filter made of a dielectric material disposed between the first and second electrode plates, and wherein at least the intake grille and the second net-shaped electrode plate being detachable from the main body. |
