Filter coal-based ISO COARSE 75%
Carbon pre-filters can be used interchangeably with standard ISO COARSE 75% filters. They are fitted to the supply air duct and, like the ISO COARSE 75% pre-filter, trap large particles – dust, leaves, insects, animal hair, sand and larger contaminants (10–20 μm). A distinctive feature of carbon fibre filters is their ability to reduce unpleasant odours originating from polluted air outside the building. They are particularly recommended for users living in the vicinity of houses or buildings heated with solid fuels.
