Abstract
The filter device for air purification has an electrification grid supplied with a high voltage of negative polarity and arranged on a plane transverse to an air flow for negatively charging particles present in the air. A partition is arranged at an angle in front of the electrification grid so as to convey the stream of air toward a narrower region. A negatively charged deflector plate and a positively charged collector plate, which face one another at a short distance, delimit a respective narrower region for respectively repelling and attracting the negatively charged particles. A germicidal lamp is arranged at an opening of the deflector plate and illuminates the collector plate substantially along its entire length in a direction which is transverse to the air flow.

Filter device for air purification, comprising:
- an electrification grid supplied with a high voltage of negative polarity and arranged on a plane transverse to an air flow, for negatively charging the particles present in said air by electron bombardment;
- a partition arranged at an angle in front of said electrification grid so as to convey the stream of air toward at least one narrower region;
- a negatively charged deflector plate and a positively charged collector plate which face one another at a short distance so as to delimit said respective narrower region for respectively repelling and attracting said negatively charged particles;
- a germicidal lamp arranged at an opening of said deflector plate for illuminating said collector plate substantially along its entire length in a direction which is transverse to the air flow.
