How is the removal of dust performed on an electronic air cleaner?

The removal of dust from an electronic air cleaner is commonly achieved by washing it off. Electronic air cleaners utilize an ionization process that charges particles in the air, allowing them to be attracted to collection plates or filters. Over time, these charged plates accumulate dust and other particulates. To maintain the efficiency of the air cleaner, it is important to regularly clean these plates. Washing the filters or plates allows for the removal of accumulated dust without damaging the electronic components, ensuring that the air cleaner continues to operate effectively.

This method is preferred because it helps to retain the dust collection capacity without requiring alterations to the equipment. In contrast, other methods such as vacuuming or incineration are less effective or could potentially harm the equipment. Chemical treatments might also pose risks to materials in the electronic air cleaner and are not standard practice for cleaning these devices. Thus, washing off the dust is the most suitable and recommended method for maintaining electronic air cleaners.
