Provox Micron HME is not only an HME, Provox Micron HME
is also equipped with a layer of electrostatic filtration material. The
filter consists of synthetic fibres which, during the manufacturing
process, generate electrical charges on the fibre surface. The result
is a highly stable, coarse fibred electrostatic filter media with high
efficiency against sub-micron particles (see Technical data) and low
air flow resistance.
