Abstract
An electronic air filter assembly includes filter media disposed on opposite sides of an electrified charging screen. The filter media and charging screen are held between outer screens. The outer screens are held together in an assembled condition by pressure-sensitive securements and can be pulled apart to disassemble the filter assembly by applying an outer screen-separating force sufficient to overcome the holding force of the securements.
