Although the ionic air purifier removes harmful particles from the air, it is easy for them to be returned to the air. This is because the particles are on the floor and other surfaces of the room. Regular activity in the room can easily stir the particles back up. As a result, the harmful particles are put back into the air. Some ionic air purifiers, however, have special electrostatic precipitators. Electronic precipitators trap particles on charged metal plates. These plates need to be cleaned regularly, however, in order to be effective.
