Filter box

Healthier indoor climate

The filter box is an add-on for balance ventilation that filters nitrogen (NOx) and sulphur oxide from the air. It does this by means of an activated carbon filter and an antismog filter. The ideal solution when the inlet of the ventilation system is close to a chimney, for example. Not only harmful nitrogen and sulphur particles are filtered out, but also nuisance odours.
