What is the maximum internal voltage that electronic air cleaners can operate with?

Electronic air cleaners often require high voltage to operate effectively, primarily for the purpose of ionizing particles within the air that pass through their systems. The process of ionization is achieved when air passes through an electrical field, which requires a significant voltage.

The correct answer, 5000 volts, reflects the operational capabilities of these devices. At this voltage level, electronic air cleaners can create a strong enough electric field to capture and eliminate particles like dust, pollen, and smoke from the air, improving indoor air quality. This high voltage is necessary to overcome the resistance of the air and ensure the effective ionization of particles, making it a critical component of their functionality.

Lower voltage options—such as 120, 240, or 500 volts—would not provide sufficient energy for the ionization process necessary in electronic air cleaning systems. Therefore, they are not suitable operational voltages for electronic air cleaners.
