Abstract
An electric polarizing air filter has a charged screen of high resistivity to suppress avalanche discharge and permit use of a higher polarizing voltage.
Claims2
An electronic air filter of the charged media type comprising at least an outer screen and at least one charged screen adjacent said outer screen, said screens having dielectric trapping media positioned there between, said charged screen being made of a material that exhibits high resistivity sufficient to suppress avalanche discharge between said screens.
