Electrostatic filters use an electrostatic charge to attract pollutants and trap them on collector plates. These filters are ideal for people who care not about changing the HEPA filter, but if the collection plates are not cleaned regularly, they quickly lose their effectiveness.

Responsible media filters provide an electrostatic charge pollutants before they gathered in a traditional filter. Charged filter media are generally very effective, but as an electrostatic filter, they quickly lose efficiency and can be frequent and costly filter changes required.
