Abstract: A negative ionization cell for negatively ionizing fine, ultrafine or nanoparticles present in an air flow defined by fumes, vehicle exhaust gases or indoor environments is disclosed. The cell has a body defining an ionizing part having first and second portions which are elongated, preferably plate-like, and facing each other. The first portion has a negative voltage to generate a potential difference with the second portion. The first and second portions also define a passage for the air flow and the first portion supports a plurality of elongated and sharp-pointed bodies projecting into the passage for the air flow and orthogonally to the air flow. The elongated and sharp-pointed bodies generate an electron flow, directed toward the second portion due to the potential difference and intercept the solid particles in the air flow to negatively charge them. An air purifier including the negative ionization cell is also disclosed.
