In highly industrialized countries experiencing important atmospheric pollution issues, ensuring a healthy environment has become a necessary requirement, also for the prevention of dangerous illnesses. FCP electrostatic filters have been conceived and developed for residential sector applications, both as an integration for more complex systems, and as a stand-alone solution for air exchange and renewal systems. Electrostatic filters are installed and removed by simply sliding them across the equipment filter holder frame. The built-in electronic power input circuit is equipped with LEDs to notify the user that the filter is working correctly. A range of electrostatic filters for residential applications, customized based on the different sizing and air load needs, is also available.
