Abstract:
An air filter arrangement is provided for filtration of particles in an airflow having an airflow direction. The air filter arrangement includes an electrostatically charged filter, a first ionization device, and a second ionization device. The first ionization device is arranged upstream of the electrostatically charged filter and the second ionization device is arranged downstream of the electrostatically charged filter. An air filtering apparatus is also described.
