IS THIS PURIFIER REALLY WORKING IS IT a hepa or carbon filter?

Most particles in the air are neutral in charge. Meaning they have the same amount of negatively charged electrons, and positively charged protons. A common type of air purifier uses what is called corona discharge air purifier. These type of air purifier create molecules called ions. When particles pass through these air purifiers electric current makes these particle either positively charged or negatively charged. Once these "ionized" particles from the air makes contact with objects that are opposite of thier charged, they stick to them instead of lingering in the air, or they may clump with other particle untill they are too heavy and fall to the ground. Filter types air purifier are not so good since they require periodic filter replacement. These type of air purifier are usually part of the air conditioning system. The purifier picture I see are the ones i just mentioned, and they are not filter types.
