What type of particles are carried through the charged-media air cleaner and attracted to the filter media?

The correct concept relates to the type of particles that interact with charged media in an air cleaner. In such systems, particles become charged—either positively or negatively—after being exposed to the electric field created by the charged media. This charge attracts the particles to the oppositely charged filter media.

In a charged-media air cleaner, the function relies on the principle of electrostatic attraction, where charged particles are effectively captured by the grounded or differently charged surfaces of the filter.

Neutral particles do not possess any net charge and therefore would not respond to the electrostatic field created by the charged filter media. Similarly, the concepts of polarized and non-polarized particles aren't directly relevant to this mechanism in the context of an air cleaner, as it is primarily the presence of a charge that governs the attraction to the filter media.

Thus, it is the charged particles that are crucial to the operation of a charged-media air cleaner, making that the correct answer.
