The producers recommend that filters be changes at least once or twice a year, at the beginning and end of the heating season. The interval also depends on the location and the intensity of ventilation.
Old and dirty filters lead to a pressure drop in the ventilation system and, as a result, the volume of fresh air inflow decreases, which worsens the indoor climate.
An old, dirty filter can contribute to the spread of mould in the ventilation system. (especially in humid climates), which can be a health hazard.
The new filter has the best air permeability levels and, as a result, savings can be made in electricity costs for the fan unit.
STORAGE AND DISPOSAL:
For long-term storage, keep in a dry place. Used filters can be disposed of with regular household waste.
