What is the approximate secondary voltage range of an electronic air cleaner?

• A. 120 - 240 volts
• B. 600 - 1,000 volts
• C. 2,000 - 5,000 volts
• D. 9,000 - 12,000 volts

Answer: (D)

The secondary voltage range of an electronic air cleaner typically operates at a high voltage to effectively ionize particles in the air. The range of 9,000 to 12,000 volts is consistent with the operational requirements of these devices, which need sufficient voltage to generate an electric field that attracts and captures airborne particles, including dust, smoke, and allergens. In electronic air cleaners, the high voltages applied create a corona discharge that ionizes particles, allowing them to be drawn to and collected on oppositely charged plates. This high-voltage range ensures optimal performance and efficiency in purifying the air, making the selected answer the most suitable choice based on the operational characteristics of these systems.
