Method for preventing microbial growth in an electronic air cleaner

摘要

A method is provided for preventing microbial growth on the collector plates (42) of an electronic air cleaner (10) by directing germicidal light, advantageously ultraviolet light, upon the surface of the collector plates (42) and the particulate material deposited thereon. At least one germicidal lamp (50) is disposed to irradiate ultraviolet light upon the collector plates (42) to destroy microbes that might be growing on the particulate material collected on the plates (42).
