What internal voltage is typically measured in an electronic air cleaner?

In an electronic air cleaner, the internal voltage that is typically measured is around 5000 volts. This high voltage is essential for the operation of the electrostatic precipitator technology used in these devices. The high voltage generates a corona discharge, which ionizes particles in the air that pass through the cleaner. This ionization causes the particles to become charged, allowing them to be collected on oppositely charged plates within the unit, effectively removing pollutants and particulates from the air.

While other voltage levels, such as 120V or 240V, are common in household electrical systems, these do not represent the specific operating condition of an electronic air cleaner. The much higher voltages of 10000V and 5000V are more aligned with the requirements for creating effective ionization, but 5000V is sufficient for many models and is typically the standard found in most electronic air cleaners. The choice of 5000V reflects a balance between efficiency and safety in the design of these air filtration devices.
