Charged-media non-ionising filters
Illustrated Guide to Ventilation (BG 2/2009), compiled by Kevin Pennycook and published by BSRIA in 2009, states: ‘Charged-media non-ionising filters include filter media in the form of mats between plates that generate an electrostatic field. The strong electrostatic field generated through the dielectric material of the filter polarises the dust particles which are then attracted to the mat. In a charged-media ionising filter the particles are initially charged and then collected on a charged-media filter.’
